WIMPs versus WIZs, Weakly Interacting Zombies

March 27, 2023

WIMPs are Weakly Interacting Massive Particles, the hope of particle physicists. WIMPs have not been observed yet (in 2023). Particle physicists hope that some sort of WIMPs, as yet unknown, are what Dark Matter is made of. But maybe Dark Matter is made of WIZs, Weakly Interacting Zombies. (as SQPR holds: in SQPR, large scale quantum collapse leaves a mass-energy residue… Those weakly interacting zombies…)  

Dark Matter has been a riddle for a century (a Swiss from Caltech, Zwicky suggested it first). That there is something cosmically flouting the laws of known physics is blatant, and for all to see (if one has a telescope). Two-thirds of spiral galaxies are barred, including our own giant Milky Way. The bar moves rigidly, obviously, and this is an obvious contradiction with having a lot of mass at the center [1]. Either gravity fails (as MOND has it) or there is a lot of mystery mass  (Dark Matter) away from the center.

I had the pleasure over the weekend to talk with David Schlegel from LBL, one of the most cited US physicists. He studies dark energy, dark matter, and fundamental physics.

Here are some key points of our exchange which I think are the most important:

  1. David firmly believes in WIMPs. He believes not all the “phase space” has been studied and the particle accelerators will find WIMPs in areas not yet surveyed… “within a decade”. 
  2. David agrees that Dark Matter (DM) can’t be explained by neutrinos, because neutrinos don’t stay in place.  
  3. David does not believe MOND (MOdified Newton Dynamics is a potential explanation for DM “anymore”. Not in the “last ten years”. So I asked him if it was because of the Bullet Cluster and similar situations, and he said yes. Too many of these. I told him I NEVER believed in MOND, because it looked too ad hoc. David retorted that everything is ad hoc (in science)… So he got on the receiving end of an ad hoc versus logical-principled approach to science. I gave the example of Kepler (ad hoc) versus Newton… In truth, though, even Kepler was not ad hoc, in the sense that he made a deliberate “war on Mars” (which had been launched by Kepler’s mentor Tycho).
  4. I pointed out the philosophical difficulty of having as we have in the Big Bang model now TWO inflation mechanisms, one observational (Dark Energy, demonstrated first at Berkeley LBL cosmology and astrophysics group), the other a theoretical necessity to make the Big Bang theory work. That made him smile nervously. He said that after all they are perhaps the same (Wait! What? That’s what SQPR holds). David also said that it would all be figured out in detail within ten years: traces of cosmic inflation should be found… or then, well, inflation would be disproven.

For once I was polite and guarded, in part because I had filled my weekly quota for new enemies earlier that day. I didn’t insist on Big Bang Trouble,

that those early enormous galaxies with old red giant stars contradicted LCDM… I didn’t point out that, without cosmic inflation, the Big Bang model doesn’t work. I didn’t point out that finding a WIMP candidate is only part of the story, and not the most important part… Most crucially, one needs to explain why the Dark Matter is where it is. SQPR, which is a geometric mass-energy theory, does this effortlessly.

All this tells me that core official, ultra expert cosmology is putting all its hope in WIMPS, and keeps on being ultra-confident of the Big Bang religion.

Never mind that the most recent space telescope is apparently verifying a stunning prediction of SQPR, namely huge very old galaxies (and they should be poor in Dark Matter).

Cosmology? One more dimension in which the next decade is going to be fascinating…

[1] centrifugal acceleration is ~ vv/d (v being the speed of the orbiting object, d its distance to center of the rotation) gravity is ~ 1/dd. Equating both, we get: vv = 1/d, or v is the square root of the inverse of the distance. So v should diminish as one gets away from the center…. But the bar is rigid… and that means that the speed v is proportional to the distance d. So the discrepancy is d^3/2!

Big Bang Big Trouble: More Galaxies Than Available Gas? Quantum Way Out: SQPR!

March 14, 2023

Distant galaxies seem to be far more massive than expected by today’s Bigbangers (sneakily pejorative neologism!). To the point of impossibility! The James Webb Space Telescope (JWST) spotted galaxies with masses up to 100 billion times that of the sun that must have formed faster than current models can explain (by comparison our giant Milky Way is 15 times more massive, 1.5 trillion solar masses).

By studying a small patch of sky, with the JWST, Swede physicist Ivo Labbé at Swinburne University of Technology in Australia and colleagues measured the distances to six massive galaxies using their cosmic redshift. Ivo Labbé’s galaxies are (now) all around 30 billion light years away. According to the Lambda Cold Dark Matter Big Bang model, those galaxies formed within 700 million years of the big bang, so 13 billion years ago.

Objects further from our Milky Way galaxy group  move away from us ever more quickly, the further they are from the expansion of the universe. Said expansion was discovered by a number of astronomers more than a century ago, including the famous Edwin Hubble, a greedy lawyer turned astronomer and according to some, an expert plagiarist, who used the world’s most powerful telescope (at the time)… besides earlier discoveries from several European astronomers (Reynolds, Lemaitre, etc.)

Distant galaxies appear redder than nearby galactic clusters because the light waves coming from them are literally stretched by cosmic expansion [1]… (This cosmic shift shows that each photon of light is nonlocal, by the way. If, as Einstein suggested in 1905 a photon was just a point, it would not stretch, hey.)  

“I would have guessed that galaxies like this would not exist this early in the universe,” says Pieter van Dokkum at Yale University (Connecticut), part of the research team. That is because the galaxies all had masses at least 10 billion times the mass of the sun, with one weighing in at 100 billion solar masses. From LCDM models of galactic evolution, we would expect galaxies as young as these to be relatively low-mass, without many stars at all, and then they would grow over time until they became more like our own Milky Way galaxy, which a mass of about a trillion solar masses.

Indeed in the Big Bang LCDM model, galaxies grow around cores of Dark Matter, present from the start. In LCDM massive  elliptical galaxies take much time to grow to their mass through fusion of smaller galaxies. Low-mass galaxies form first, and then the star-forming galaxies merge as they crash into each other. A contemporary elliptical must contain stars that formed over many billion years ago in the merger precursors. But observed, real elliptical galaxies formed very fast, and very early. They appear to have been the first galaxies to have emerged after the Big Bang, forming from the single collapse of a giant post-Big-Bang gas cloud.

These young galaxies observed by the JWST in 2022 are more massive and more compact than expected than the LCDM Big Bang. “What could be going on is that the centers of galaxies form very early, earlier than we thought, then the rest of the galaxy builds up around them,” says van Dokkum (this is exactly what SQPR predicts). “I suspect that we’re looking at not finished products, but beginnings that happened very quickly.”

If all of this holds up with further investigation, then we are looking at having to rethink some of the early history of galaxy formation,” says Andrew Pontzen at University College London.

Further investigation is crucial. That follow-up will consist of detailed observations and analysis of the galaxies’ light spectra with JWST, which van Dokkum says could take about a year. Stealthily the mood is propagating that if these findings do hold up, it may be a problem for our understanding of the universe more generally, not just galaxy formation. “It was pointed out to us after we submitted the paper that there wasn’t actually enough gas in the universe at that point to form [as many massive galaxies as this study suggests] – and that was a bit of a shocker,” says Labbé. “If you form these monsters, and they contain more stars than the available gas in the universe, that’s a bit of a problem.” Indeed, one may say so. LCDM is vulnerable, because it’s a very steep pyramid of hypotheses. Remove one, and the whole thing collapses.

In the 1930s Swiss Caltech astronomer genius Fritz Zwicky discovered that the outer stars of galaxies were rotating at the same speed as the inner ones. Assuming that mot of the mass was in their stars, galaxies violated the fundamental Third Law (1618) of Johann Kepler, which states that in a rotational system held together by gravitational attraction, the objects furthest from the center revolve more slowly than those closer in (the square of the period is proportional to the cube of the radius). For example, Mercury revolves around the Sun in 88 days, the Earth in 365, Jupiter in seven years, and Pluto in 90,520 days!

To have the outer stars of galaxies rotate as fast as the inner ones is as outrageous as if Pluto revolved around the Sun in 88 days, over a thousand times faster than it actually does. Galaxies rotate like solid plates! The matter is beautifully exhibited by galaxies with a bar in the middle: the bar moves as a solid straight mass! Then it was found galaxies in clusters moved as fast as they should if the mass of the clusters were ten times greater than it actually seem to be (to evaluate .

The solution to this is the Dark Matter Hypothesis (DMH); a mysterious still-unknown gravitational mass holding all the stars in its grip. One thing that DMH, by itself, does not explain is why the Dark Matter is where it is, in particular places and often segregated from normal matter. For example why is Dark Matter in the suburbs of giant spiral galaxies rather than in the center? That, once installed somewhere, Dark Matter wouls stay there (say in orbit around the center of a galaxy at a particular distance) is not surprising, because Dark Matter doesn’t interact much, except gravitationally (otherwise we would see it!)

So it’s not just Dark Matter that is needed, but also explaining why Dark Matter is positioned where it is (a conventional explanation with ions held in particular places by electromagnetic fields is imaginable; that’s what some Italians proposed; we will see what specialists say,

TIME FOR SUB QUANTUM REALITY?

Sub Quantum Physical Reality (SQPR) assumes that the Quantum Waves used to compute in Quantum Physics are “real”: “real” means that the Quantum Waves are not just knowledge waves, they carry an energy-momentum of their own which can be torn to shred when they collapse to form “particles” when the waves are spread over too great a distance. The leftover, non-”particle” debris is Dark Matter.

SQPR weakens field carrier bosons over cosmic distances, while creating a hidden thermodynamics which pushes space away, causing the appearance of Dark Energy, inflating the universe.

Bohr, when presented to alternatives of Quantum Mechanics, simply said: “the difficulty is that they are not crazy enough”. SQPR should be crazy enough: instead of holding the universe together only with Henri Poincaré’s constancy of the velocity of light, it gets subtle about it, and the true architecture of the cosmos is from the superluminal entanglements of the Quantum Interaction. 

Having already one reason for cosmic expansion, SQPR does away with standard Big Bang cosmic inflation, while keeping Dark Energy (DE is observed; Cosmic Inflation during the big Bang is just a hypothesis to make the Big Bang work) … And thus the universe is much older than it looks. So giant elliptical galaxies had plenty of time to appear, from giant gas clouds collapsing.  The geometry of a giant elliptical galaxy is not favorable to the apparition of Dark Matter, because the mean free path of a particle is below the exponential radius of the Quantum Interaction.

The apparition of spiral galaxies comes from a combination of gravitation and conservation of angular momentum. According to SQPR, the spiral geometry is favorable to the apparition of Dark Matter. Hence the accelerating expansion of the universe as spirals appeared.

SQPR goes far, explains a lot, by supposing little, and what’s supposed is very natural. LCDM may well prove to have been a collective hallucination (those who may feel I am too confrontational are invited to look at cosmic inflation, a completely ad hoc hypothesis… needed for the basic Big Bang theory, so even more basic than LCDM).

In the great scientific revolutions, the preceding paradigm is found barking at the wrong tree, and it was not even a bush…

Patrice Ayme

How compact galaxies grow in the SQPR model: Dark Matter tends to appear where the collapse free entanglement radius is greater than the SQPR exponential function (technical differential geometry allusion)… in other words, on the outskirts of the compact galaxy, which then tends to expand in that Dark Matter belt, both from the inside, out, and from the outside, in:

Big Bang Trouble: Old, Distant Galaxies Are Huge Monsters

March 13, 2023

Big Bang theory was predicting the most ancient galaxies to be tiny… But the new space telescope can see them, and some are huge…  

The Big Bang theory in its modern incarnation, LCDM, Lambda Cold Dark Matter, consists of a chain of nested hypotheses with attending “tooth fairies” to make it work [1]. Now there is precision cosmology, and many results, say of the CBR (Cosmic Background Radiation) fit the data exquisitely… Maybe all too well: That reminds me of Ptolemaic astronomy, when all was perfect (astronomer and count Tycho found the cheating only 15 centuries later…) I am of the opinion that there is a possible different mechanism to produce CBR (so not just redshift from expansion but also from a tired light effect coming from cosmically sized Quantum Interactions; Zwicky, the discoverer of Dark Matter also suggested “tired light”, that’s generally considered to be wrong, but Zwicky suggested no mechanism; SQPR does). 

Some of these hypotheses of the Big Bang are quite out of this world. For example, the Big Bang, even without LCDM, has to grow space at one hundred billion trillion times the speed of light (10^23 c). 

The LCDM model makes very specific predictions. So early galaxies are supposed to be small and disorganized… However, in truth… Instead we are seeing instead large, well-organized galaxies, which should not be there so early after the BB. The haggard majority of astronomers has to admit that some important ingredient in LCDM is missing, or something is wrong entirely. I propose the latter, on a truly cosmic scale.

“Lambda” comes from Einstein. It was a cheat factor Einstein introduced to explain that the universe was static: it neither collapsed nor expanded. However, within a few years the universe was found to be expanding. Einstein called Lambda “it’s biggest mistake”… because otherwise he would have “predicted” the expansion (silly boy). So “Lambda” was viewed with horror and consternation, as the poster boy of ad hoc hypotheses, for seventy years, until around 2000 CE when it was found, by studying super novas as distant candles, that the cosmic expansion accelerated, so “Lambda” had to be plugged back into the General Relativity equation, which now basically reads as follows: 

Curvature + Lambda = Energy-Momentum  

So then Eistein’s biggest error became another Einstein insight…. (My view of Einstein’s biggest error is that it is much  bigger than that: his assumption of point-like “particles”… which is increasingly disproven by the most recent experiment, not just my opinion. The field is moving so fast, I didn’t write about these yet.)

The Dark Matter problem is that gravity as the inverse square law doesn’t seem to work in view of the apparent repartition of matter around galaxies and galactic clusters

The inverse square law for gravitation was proposed in 1645 by the French astronomer Ismaël Boulliau (aka Bullialdus). The law was demonstrate by Newton when he deduced from it Kepler’s laws. The 1/dd behavior of gravity is also the first approximation of General Relativity, GR, the modern (1916) theory of gravitation of Einstein and his colleagues (Hilbert, Besso, etc.). So if 1/dd falls, so does GR.

However, confronted to this Dark Matter problem all over, some then tried the oldest and most basic method of science: if it doesn’t fit, you must that quit! When confronted with a mystery, one tends to go to the simplest explanation. In the case of “Dark Matter” that would be neutrinos or a similar new type of particle, say from supersymmetry, interacting very little with ordinary matter. But particle physicists found no such particles. They are still searching.

Periodically some scientists, typically Italian, located below Gran Sasso (the great stone.), proclaim they have solved the problem… But they are found to be wrong. Gran Sasso experiments should be funded, but Italian science has a funding crisis, so is prone to enthusiastic claims to justify said funding… Most recently Italians claim they found (again) all the Dark Matter, and it was all ions, and there were too many of them… (I would be naturally very disappointed if they were right…)

Neglecting this Italian distraction, the next logical possibility is to modify gravity to fit the apparent rotation curves of galaxies. This sort of method is curve fitting, it has a glorious past: Kepler did it…within a generation or so Kepler laws were (more or less) deducted from the inverse square law and the basic laws of mechanics by Newton and company. So modifying gravity should not be taken lightly. Our GPS works with GR…

Modifying gravity ad hoc is called MOND: MOdified Newtonian Dynamics.  A first problem here is that Ismael Boulliau (Bullialdus) has a little reasoning for the 1/dd law, namely that would be the natural decrease over a distance d, of the density of particles. Boulliau made the explicit analogy of graviation with light (if it consisted of particles). Some may object that Boulliau’s work is rather trivial. Maybe, but it’s way better than no fundamental reason at all, as in MOND.

Moreover, Bouillau may well have been right, in light of Planck’s Quantum hypothesis, which makes light into particles (or at least packets of energy, an idea reinforced by Einstein in 1905)… So Bouillau contradicts MOND with a reason all the better, that it is very simple…

If there are no Dark Matter particles, and modifying gravity doesn’t work the next and only step is to modify Quantum Physics, and that is what Sub Quantum Physical Reality (SQPR) does. It turns out that SQPR changes cosmology on a vast scale. No more “tooth fairies” and a cascade of ad hoc hypotheses… Patrice Ayme The universe is lyrical in the most gigantic way:

Distant galaxies as seen by the JWST in 2022…

[1] As astrophysicist and cosmologist Stacy McGaugh, a MOND partisan, puts it: “Bear in mind that there are many forms of feedback. That one word [feedback] upon which our entire cosmology has become dependent is not a single auxiliary hypothesis. It is more like a Russian nesting doll of multiple tooth fairies, one inside another. Imagining that these different, complicated effects must necessarily add up to just the right outcome is dangerous: anything we get wrong we can just blame on some unknown imperfection in the feedback prescription. .. This is like putting a bandage on an amputation and pretending like the treatment is complete.

The universe is weirder than we know, and perhaps weirder than we can know. This provides boundless opportunity for self-delusion.

SQPR GENERATES DARK MATTER, DARK ENERGY (in a nutshell)

August 24, 2022

SQPR, Sub Quantum Physical Reality, introduces the notion of Quantum Interaction: anything involving Quantum Entanglement rupture is viewed as an interaction. This is a new type of interaction, right. And it’s also not just verbiage: interaction means finite speed. In Quantum Physics, as it presently exists, in its CIQ (Copenhagen) interpretation, QI is instantaneous. So SQPR and CIQ make different prediction: SQPR predicts the universe as observed. CIQ does not.

Why Quantum Physics, so far, does not view Quantum Interactions as interactions is because of prejudice: it assumes nothing changes when entanglement is activated: simply, we can’t do something with it now, so we, 20C Quantum Physics, assume it has no effect. The reason is technical: the arena of a Quantum happenstance is a Hilbert Space representing the experiment at hand… And it’s assumed to be just one place, thus denying space (one of the reason why it’s hard to integrate Quantum and Relativity!)

However, that nothing happens when entanglement is activated is not what the Bell Inequality shows. Bell Inequality shows something changes, because any Classical Hidden Variable models, all of them, give a different result. And something big, thus, indeed, changes from the Quantum Interaction. SQPR says Dark Energy and Dark Matter are macroscopic effects of the Quantum Interaction.  

***

SQPR assumes that QI has a finite range and propagates at finite velocity (much higher than the speed of light by a factor of at least 10^23). The metric used is phase metric to measure how far QI goes, the number of matter wave wavelengths (so higher frequencies, shorter Euclidean distance, hence effects on QFT). As matter waves have an average wavelength (since matter has an average energy-momentum), it means in practice that the QI range will translate in Euclidean distance.

Beyond that range, some mass-energy gets lost during QI. However, other Quantum characteristics of the particles involved stay the same in the main “particle” part: UP Quark stays UP Quark, etc. The Dark matter part is stripped of everything except energy-momentum. That remnant is what creates Dark Matter and Dark Energy.

Before QI, there was an energy-momentum. After QI, same. Thus, when QI ruptures, energy-momentum should be conserved, ergo some of the Dark Matter leaves with momentum, and that momentum will point in the opposite direction of where the matter it separated from is! Hence a repulsive force between matters clumps, Dark Energy!

 

In Quantum Field Theory, SQPR implies a natural renormalization, since the QI range is inversely proportional to the total number of matter-wave wavelengths.  

 

New fundamental concepts are the deepest breakthroughs. This is true all over thought, all over science, even in math and physics. Evolution (also found by Ancient Greeks), inertia, momentum (Buridan, 14C), Kepler’s laws (arising from Tycho’s effort), laws of mechanics (established over several centuries by many), electromagnetic field (many contributors over centuries), the Quantum (Planck), plate tectonic (Wegener), are examples….

The idea of a-toms: what can’t be divided, was a fundamental breakthrough. 

Intriguingly, Quantum Physics has stood the idea of atoms on its head: what rules now are waves and fields, Matter Waves, Quantum Fields…. Fields comprise the idea that there is something there, even if we don’t know what it is. Fields are intrinsically nonlocal. Einstein however insisted that the photon was an atom of light: not divisible, and its energy concentrated at a point, thus, local. I view this as a contradiction. QFT implicitly contradicts Einstein, but I propose to go further… by making the matter field divisible, thus atoms, in a sense, divisible… new predictions appear. 

Quantum Physics says there are no points (because all is waves, and waves can’t be just at a point, this is the essence of Quantum Uncertainty). If there are no points, atoms can’t be made of points (indeed QFT looks only at fields, which are intrinsically NOT points). So division of the (quasi) infinitely small is not possible to start with, in the traditional sense, as it would involve points. But rupture of entanglement does not depend upon the locally small, quite the opposite. 

It took around 2,000 years to go from the erroneous Aristotelian physics, to the notions of inertia and momentum (with Buridan, 14C). The switch could have happened right away, because Aristotle made a really trivial mistake (he overlooked resistance to motion obviously caused by the medium in which motion happened).

Hopefully we can learn from this mistake.

It’s pretty obvious that entanglement should have finite range, or a finite interection speed. Newton would have understood this (he thought his gravity theory had the flaw of being instaneous at a distance; Laplace corrected this a century later, simply by introducing an interaction speed, thus making gravitational waves appear; something Poincare then extended to spacetime after another century). Introducing spatial limitations to the Quantum is only natural.

P/S: Early results from the James Webb Space Telescope seem to show monstruous galaxies, very far away, full of new stars… something… which the Lambda Cold Dark Matter model (“Big Bang”) does not predict.. .. But that I was hoping for! SQPR, an axiomatically leaner theory than the LCDM model does predict a much older universe, thus with much more large galaxies at a distance (held by their own matter gravity rather than by DM, as SQPR says that Dark Matter is an emerging quantity and quality).

Dark Matter Proves Quantum Mechanics Wrong, SQPR Right

June 29, 2020

We live in barbarian times when oligarchs block intelligent discourse to the masses. As in the past, even intelligent physics gets blocked. The NYT has 6 million subscribers (including me, and blocked the following comment to an article on the foundations of Quantum Mechanics)

What if the proof of SQPR (Sub Quantum Physical Reality) was already cosmically in full sight? Let me explain. Each Quantum process comes with a (Hilbert) space. Within it, the wave one computes probability with, the Quantum Wave, evolves with time as a one parameter group. Time is not treated like space [1]. The Quantum Wave collapses suddenly, all over, when a probability is extracted from it. Multiverse theory claims that each outcome is its own universe (that means zillions of universes inside a proton). A potential way out is instead to assign a reality to the Quantum Wave. That means attributing to the QW some mass-energy (however minute), wherever it is to be found, and an objective collapse propagation speed to the QW (it has to be greater than 10^23 c).

Rotation of curve of Spiral galaxy Messier 33 (Triangulum, the third largest galaxy of the local group after Andromeda and the Milky Way). The galaxy rotates as if it were an increasingly denser plate the more one gets away from the center…

The full SQPR is nonlocal (in the sense of that experimentally demonstrated superluminal entanglement). An immediate consequence of this picture is that, in some large geometrical situation, a mass-energy residue will form …which will behave exactly like Dark Matter; so Dark Matter would be a proof of the objective collapse theories! The difference between this and the De Broglie guiding wave theories is that the assignment of (minute) mass energy to the guiding linear wave… and making the “particle” into the central nonlinear part of the QW. 

We need a SQPR (Sub Quantum Physical Reality). Yale’s Devoret and Minev found that some Quantum Jumps are preceded by a preparation phase which can be reversed, thus demonstrating SQPR [2].

“Fuzzy” Dark Matter & Sub Quantum Physical Reality (SQPR)

October 17, 2019

Abstract: An early Quantum universe would have appeared “fuzzy”, and striated, from Quantum self interference… If one adopts one basic consequence of my own SQPR theory: Dark Matter is made of ultra-light, ultra-low momentum particles. A team of physicists at prestigious institutions by adopting this conclusion of SQPR, one gets a drastically different looking model explaining the filament nature of galaxy distributions. (This completely new approach is indirectly rather supportive of SQPR… and very different from the usual LCDM; it should be testable soon, with new telescopes under construction…)

***

According to official, ruling Big Bang theory, Dark Matter was the starting ingredient for coagulating the very first galaxies in the universe. According to that “LCDM” model, shortly after the Big Bang, particles of Dark Matter clumped together in gravitational “halos,” pulling surrounding gas into their cores, which over time cooled and condensed into the first galaxies. [1] 

Thus a curious situation: Dark Matter is considered the backbone to the structure of the universe, while physicists know very little about its nature, because the DM “particles” have so far evaded detection.

Now scientists at MIT, Princeton University, and Cambridge University have admitted the obvious, namely that the early universe, and the very first galaxies, would have looked very different depending upon the exact nature of Dark Matter.  They simulated what early galaxy formation would have looked like if Dark Matter were “fuzzy,” rather than cold or warm. “Fuzzy” here has a precise definition: it means very low momentum DM “particles”. Such “fuzzy” particles are what my own theory, SQPR is full of, as a consequence of my hypothesis that Quantum Mechanics is LOCAL.

Left is the conventional distribution of galaxies prediction of the conventional Big Bang (“LCDM”). Center is that with “warm” dark Matter. Right is the Quantum “fuzzy” DM model (compatible with SQPR).

Light Mechanics, electromagnetism, is local: this is also called Relativity (Poincaré named it thus). QM being a generalization of Light Mechanics, it is natural that it would be local too: this is the fundamental axiom of SQPR

In that most widely accepted scenario, the so-called LCDM (Lambda Cold Dark Matter) model of the early universe Dark Matter is Cold: it is made up of slow-moving particles that, aside from gravitational effects, have no interaction with ordinary matter (SQPR readily explains why DM doesn’t interact but gravitationally). 

In LCDM, Warm Dark Matter is thought to be a slightly lighter and faster version of Cold Dark Matter (it has been heated by galaxies). 

Fuzzy Dark Matter, is, for official physics, a new concept, something entirely different, consisting of ultralight particles, each about 1 octillionth 10^(-27) the mass of an electron (the Cold Dark Matter particle of LCDM are far heavier — about 100 times more massive than an electron). Repeat: the proposed mass for Dark Matter particles in this new simulation is the mass of an electron divided by 1,000,000,000,000,000,000,000,000,000

Now we are talking. This is the sort of numbers my own theory, SQPR considers.

The Millennium Simulation (below) is an example of an over 10 billion particle simulation that tries to reproduce the cosmic web of dark matter upon which exist galaxy clusters, filaments, and voids we see today. The LCDM (Lambda Cold Dark Matter) model of the universe assumes a flat universe now dominated by a cosmological constant Lambda, Einstein’s Cosmological Constant (Dark Energy?). As I said, the cosmological large structure formation is dominated by cold (non-relativistic) dark matter.

A view of the distribution of dark matter in our universe, based on the Millennium Simulation. The simulation is based on our current ideas about the universe’s origin and evolution. It included ten billion particles, and consumed 343,000 cpu-hours (Image: Virgo Consortium)Researchers found that if Dark Matter is cold, then galaxies in the early universe would have formed in nearly spherical halos, with ten times too much mass there. But if the nature of Dark Matter is fuzzy or warm, the early universe would have looked very different, with galaxies forming first in extended, tail-like filaments. In a fuzzy universe, these filaments would have appeared striated, like star-lit strings on a harp… As observed.  

As new telescopes come online, with the ability to see further back into the early universe, scientists may be able to deduce, from the pattern of galaxy formation, whether the nature of dark matter, which today makes up nearly 85 percent of the matter in the universe, is fuzzy as opposed to cold or warm.

“The first galaxies in the early universe may illuminate what type of dark matter we have today,” says Mark Vogelsberger, associate professor of physics in MIT’s Kavli Institute for Astrophysics and Space Research. “Either we see this filament pattern, and fuzzy dark matter is plausible, or we don’t, and we can rule that model out. We now have a blueprint for how to do this.” [2]

Fuzzy Quantum Waves:

While dark matter has yet to be directly detected, the hypothesis that describes dark matter as cold has proven successful at describing the large-scale structure of the observable universe. As a result, models of galaxy formation are based on the assumption that dark matter is cold.

“The problem is, there are some discrepancies between observations and predictions of cold dark matter,” Vogelsberger points out. “For example, if you look at very small galaxies, the inferred distribution of dark matter within these galaxies doesn’t perfectly agree with what theoretical models predict. So there is tension there.” This is a euphemism: According to LCDM, the heavy DM particles should sink towards the core of galaxies, and this is exactly what is not observed. 

Enter, then, alternative theories for dark matter, including warm, and fuzzy, which researchers have proposed in recent years.

“The nature of dark matter is still a mystery,” Fialkov says. “Fuzzy dark matter is motivated by fundamental physics, for instance, string theory, and thus is an interesting dark matter candidate. Cosmic structures hold the key to validating or ruling out such dark matter models.”

Fuzzy dark matter is made up of particles that are so light that they act in a quantum, wave-like fashion, rather than as individual particles. This quantum, fuzzy nature, Mocz says, could have produced early galaxies that look entirely different from what standard models predict for cold dark matter.

“Even though in the late universe these different dark matter scenarios may predict similar shapes for galaxies, the first galaxies would be strikingly different, which will give us a clue about what dark matter is,” Mocz says.

To see how different a cold early universe could be, relative to a fuzzy early universe, the researchers simulated a small, cubic space of the early universe, measuring about 3 million light years across, and ran it forward in time to see how galaxies would form given one of the three dark matter scenarios: cold, warm, and fuzzy.

The team began each simulation by assuming a certain distribution of dark matter, which scientists have some idea of, based on measurements of the cosmic microwave background — “relic radiation” that was emitted by, and was detected just 400,000 years after the alleged Big Bang. Dark matter doesn’t have a constant density, even at these early times. There are tiny perturbations on top of a constant density field. Those perturbations would gather more Dark Matter, nonlinearly.

The researchers were able to use existing algorithms to simulate galaxy formation under scenarios of cold and warm dark matter. But to simulate fuzzy dark matter, with its quantum nature, they needed to bring in the Quantum.

A cosmological map of Interfering Quantum strings:

To the usual simulation of cold dark matter were added two extra equations in order to simulate galaxy formation in a fuzzy dark matter universe. The first, Schrödinger’s equation, describes how a quantum wave evolves in the presence of (potential) energy, while the second, Poisson’s equation, describes how that (self-interfering) quantum wave generates a density field, or distribution of Dark Matter, and how that distribution leads to (uneven) gravity — the force that eventually pulls in matter to form galaxies. They then coupled this simulation to a model that describes the behavior of gas in the universe, and the way it condenses into galaxies in response to gravitational effects.

In all three scenarios, galaxies formed wherever there were over-densities, or large concentrations of gravitationally collapsed Dark Matter. The pattern of this Dark Matter, however, was different, depending on whether it was cold, warm, or fuzzy. 

In a scenario of cold dark matter, galaxies formed in spherical halos, as well as smaller subhalos. Warm Dark Matter produced  first galaxies in tail-like filaments, and no subhalos. This may be due to warm dark matter’s lighter, faster nature, making particles less likely to stick around in smaller, subhalo clumps.

Similar to warm dark matter, fuzzy dark matter formed stars along filaments. But then quantum wave effects took over in shaping the galaxies, which formed more striated filaments, like strings on an invisible harp. This striated pattern is due to constructive interference, an effect that occurs when two waves overlap, similarly to the famous Double Slit experiment. When constructive interference occurs, for instance in waves of light, the points where the crests and troughs of each wave align form darker spots, creating an alternating pattern of bright and dark regions.

In the case of fuzzy dark matter, instead of bright and dark points, it generates an alternating pattern of over-dense and under-dense concentrations of dark matter.

“You would get a lot of gravitational pull at these over-densities, and the gas would follow, and at some point would form galaxies along those over-densities, and not the under-densities. This picture would be replicated throughout the early universe.”Vogelsberger explains.

The team is developing more detailed predictions of what early galaxies may have looked like in a universe dominated by fuzzy dark matter. Their goal is to provide a map for upcoming telescopes, such as the James Webb Space Telescope, that may be able to look far enough back in time to spot the earliest galaxies. If they see filamentary galaxies such as those simulated by Mocz, Fialkov, Vogelsberger, and their colleagues, it could be the first signs that Dark Matter’s nature is fuzzy.

“It’s this observational test we can provide for the nature of dark matter, based on observations of the early universe, which will become feasible in the next couple of years,” Vogelsberger says.

SQPR predicts less “fuzzy” Dark Matter in the earlier universe. However, a lot of the effects described by the MIT team would nevertheless happen, and for the same exact reasons. So the apparition of striated structures would not be surprising… even if LCDM was completely wrong.

Galaxy Without Dark Matter Found: Another Proof of New Physics?

March 31, 2018

ASTRONOMERS OGLE GALAXY DEVOID OF DARK MATTER!

The newfound object NGC 1052-DF2, a vast, diffuse galaxy, defies conventional explanations. It is to be feared (just kidding!) that various breakthroughs are in the offing, including in fundamental physics (if I believe that what could be true, SQPR, a proposed new foundation for physics, is really true).

The “ultra-diffuse” galaxy NGC1052-DF2, seen here in an image from the Hubble Space Telescope, is the same size as our Milky Way but contains just 1 percent as many stars. It also appears to be empty of Dark Matter. And therein a big problem for Conventional Wisdom:

Yes, that’s a galaxy… Looks dark, but without DM… Nothing the LCDM model saw coming… Is resistance to the New Physics Futile?
NGC1052-DF2 doesn’t look like a typical spiral or elliptical galaxy, but rather a loosely connected glob of star-pocked gas and dust. If it contained an amount of Dark Matter typical for a galaxy of its size, the Dark Matter’s gravity would hasten the motions of several star clusters that orbit it. Instead, van Dokkum’s team found those star clusters moving languidly around NGC 1052-DF2… That suggests Dark Matter can decouple not only from regular, visible matter, but from entire galaxies—a phenomenon LCDM cosmologists claimed couldn’t happen.

Large galaxies, radiant agglomeration of stars, are tied up together by the gravitational pull of Dark Matter, a hidden material that is revealed and observed by its gravitational pull upon the shiny stars it seems to outmass by a factor of ten (we know this from the virial theorem, which basically say: v^2 ~ M/R, where M is the global gravitational mass, v the (“dispersion”) speed, and R the radius where the speed is measured; so the higher the speed of the orbiting stars, clusters, galaxies, at the greater distance, the higher the global mass M).

Dark Matter is considered to be as a defining feature of galaxies as stars and gas… and is thought in the reigning LCDM model, to provide the gravitational seeds from which galaxies assemble and grow (a top cosmologist Sean Carroll insisted on this point in correspondence with me). I strongly disagree with the latter point (in my model, Dark Matter is EMERGENT, a fruit of the Quantum Interaction).

A galaxy without Dark Matter—or without some bizarre, twisted deformation of gravity (such as MOND) that would mimic Dark Matter behavior, in some, only some, cases, and not in cases such as the Bullet Cluster —would contradict the religion of LCDM (Lambda Cold Dark Matter) and the sect of MOND, in other words, such a heretical galaxy would shred official thinking and its main alternative. Yet that is exactly what Yale University astronomer Pieter van Dokkum and his colleagues have found, they report in a study published Wednesday in Nature.

From the horse’s mouth:

A GALAXY LACKING DARK MATTER

(Pieter van Dokkum and Al.)

Studies of galaxy surveys in the context of the cold dark matter paradigm have shown that the mass of the dark matter halo and the total stellar mass are coupled through a function that varies smoothly with mass. Their average ratio Mhalo/Mstars has a minimum of about 30 for galaxies with stellar masses near that of the Milky Way (approximately 5 × 10^10 solar masses) and increases both towards lower masses and towards higher masses… Here we report the radial velocities of ten luminous globular-cluster-like objects in the ultra-diffuse galaxy NGC1052–DF2, which has a stellar mass of approximately 2 × 10^8 solar masses. We infer that its velocity dispersion is less than 10.5 kilometres per second with 90 per cent confidence, and we determine from this that its total mass within a radius of 7.6 kiloparsecs is less than 3.4 × 10^8 solar masses. This implies that the ratio Mhalo/Mstars is of order unity (and consistent with zero), a factor of at least 400 lower than expected. NGC1052–DF2 demonstrates that dark matter is not always coupled with baryonic matter on galactic scales.

The twelve (!) authors from Yale, Harvard, Heidelberg, Santa Cruz, who used the giant Keck observatory in Hawai’i, don’t shrink from the exciting consequences:

Regardless of the formation history of NGC1052–DF2, its existence has implications for the dark matter paradigm. Our results demonstrate that dark matter is separable from galaxies, which is (under certain circumstances) expected if it is bound to baryons through nothing but gravity. The ‘bullet cluster’ demonstrates that dark matter does not always trace the bulk of the baryonic mass, which in clusters is in the form of gas. NGC1052–DF2 enables us to make the complementary point that dark matter does not always coincide with galaxies either: it is a distinct ‘substance’ that may or may not be present in a galaxy. Furthermore, and paradoxically, the existence of NGC1052–DF2 may falsify alternatives to dark matter. In theories such as modified Newtonian dynamics (MOND) and the recently proposed  emergent gravity paradigm, a ‘dark matter’ signature should always be detected, as it is an unavoidable consequence of the presence of ordinary  matter. In fact, it had been argued previously that the apparent absence of  galaxies such as NGC1052–DF2 constituted a falsification of the standard cosmological model and offered evidence for modified  gravity. For a MOND acceleration scale of a0 = 3.7 × 103 km2 s−2 kpc−1, the expected28 velocity dispersion of NGC1052–DF2 is σM ≈  (0.05GMstarsa0)1/4 ≈ 20 km s−1, where G is the gravitational constant—a factor of two higher than the 90% upper limit on the observed dispersion.

So exit MOND, Modified Newtonian Dynamics, once again! How many times do we need to kill that vampire? MOND is philosophically ugly, as it is an ad hoc theory; strictly engineered to explain a peculiar feature that is observed… Whereas my own theory, SQPR, was invented for reasons which have strictly to do with the foundations of Quantum Theory, and Dark Matter, and, moreover, Dark Matter as it turns out to be, is just a particular consequence.

***

SQPR, Sub Quantum Patrice Reality Shines, Once Again:

In SQPR, Dark Matter is created by the Quantum Interaction, at particular cosmic distances from ordinary matter, and only then. The density of matter at cosmic distances needs to be just so, otherwise Dark Matter, Patrice’s way, will NOT decouple from normal matter. Instead the galaxy will not develop Dark Matter, just DELOCALIZED Matter.

So how did we get to the present situation, as found in NGC1052–DF2? Suppose the existence of an ultra diffuse gas, on a larger scale than the Milky Way, way back in time. Under its own gravity, the ultra diffuse gas, will gather, and form stars. What is the difference with LCDM? In LCDM, Dark Matter is present to start with, seeds and accelerates galaxy formation.

Whereas in my model, the universe, being much older, perhaps 100 billion years old, there is no need for Dark Matter to seed galaxies: in complete contrast with LCDM, there is plenty of time for ultra diffuse gas to gather into ultra diffuse galaxies…. So this is not just about Dark Matter: the way I see it, it’s the entire vision of cosmology and the Quantum, which is in question.

Contextual Notes: 1) Only discovered in 2015, ultra-diffuse galaxies are thought cosmic laboratories for Dark Matter. Surely, astronomers thought, Dark Matter must provide severely needed mass to form these objects so devoid of normal stars. That thinking led van Dokkum and his colleagues to build the Dragonfly Telephoto Array, a telescope in New Mexico created for the express purpose of scrutinizing ultra-diffuse galaxies. The researchers initially used Dragonfly to study a different galaxy, which possesses an almost inconceivably gargantuan amount of dark matter, a “weird” result in and of itself. When van Dokkum and his team found NGC 1052-DF2, they expected to see something similar.

“Instead we saw the opposite, leading to this remarkable conclusion that there’s actually no room for dark matter at all in this thing,” van Dokkum says. “It’s not something we were looking for or expecting. At all. But you go in the directions the data takes you, even if it’s in contradiction to what you’ve found before.”

In Dragonfly images, NGC 1052-DF2 looked like a standard ultra-diffuse galaxy. But when the team compared them to a better image from the Sloan Digital Sky Survey, they found a surprising mismatch. What had seemed to be dim basic galactic structures in Dragonfly’s view appeared as point-like sources in the Sloan image. To resolve the discrepancy, the team scrutinized the galaxy with the Hubble Space Telescope, the W.M. Keck Observatory and the Gemini Observatory, the latter two on giant volcano Mauna Kea in Hawaii.

The point sources proved to be 10 globular clusters—compact and spherical groupings of stars orbiting the galaxy’s core. The researchers then set about measuring the movements of the clusters as a way to estimate the galaxy’s total mass. Simply put, the velocity at which clusters orbit a galaxy is related to the amount of matter—normal or dark—that a galaxy contains. Using information from the Keck telescopes, the team found the globular clusters were moving much more slowly than expected. And therefrom the tale above…

2) Without modifying vastly the age of the universe, as I boldly suggest, there are a few theories to explain how galaxies like NGC 1052-DF2 could come together without being seeded by Dark Matter (as LCDM necessarily has it). That would be a downer (for me!) but, in the interest of scientific fairness, let’s mention them.

It could be that NGC 1052-DF2 was once a glob of gas perturbed by another unseen (?) galaxy nearby, sparking DF2 star formation. Or, van Dokkum speculates, perhaps this ultra-diffuse, dark-matter-free galaxy arose from two streams of gas that collided and compressed to form a scattering of stars. Another idea, first proposed more than two decades ago by Yale astronomer Priyamvada Natarajan, suggests galaxies like NGC 1052-DF2 form from galaxy-sized globs of gas clumping together in jets ejected by supermassive black holes in large galaxies’ hearts. NGC1052-DF2 does reside in a region where such things could occur, as it lies near a giant elliptical galaxy, those are the largest galaxies, with a supermassive black hole at its heart.

Notice that, in any case, it looks bad for MOND… MOND has several variants, but, basically, says that, at the scale of 50,000 light years (say) gravity, as described by the French astronomer Ismael Bullaldius (Ismaël Boulliau), a notion picked up by Hookes, Newton, etc. and amply confirmed since on the scale of the Solar System, is actually false. Thus the virial theorem (see above), at the scale of R = 50,000 light years, should be false. But above, everybody (not just me, but also the honorable professional astronomers) assumed it was true! Not just that, but the pull of gravity was observed to be just as needed. MOND assumes it’s stronger! So MOND, in case there is indeed NO apparent Dark Matter in NGC 1052-DF2, predicts the existence of NEGATIVE mass (reference the movies Avatar? I presume?) Laughter, please!

In any case, time will tell… Paradigm shift, or overlooked subtleties? Big telescopes are coming soon to a desert near you…

Dark Matter Theories Enlighten Obscure Concept of Explanation

July 14, 2017

I have struggled with the Foundations of Quantum Physics for decades. Yes, struggle is the meaning of life, as our irascible friend the close-minded Jihadist said, and Albert Camus, too, maybe stimulated by the former, among his colleagues, the Natives of Algeria. I did the deepest studies, I could imagine, plunging in esoteric fields, so deep, I was laughed at, by those who prefer the shallows. Long ago. For example, I thought Category Theory (referred by its critics, then, as “Abstract Nonsense“) should be useful. Then even mathematicians would veil their faces, when Category Theory was evoked. Now, Category Theory is very useful, both in pure mathematics and physics.

The deepest mystery in physics is to understand the Quantum.

Some have sneered:’oh, you lunatic, there is nothing to understand.’ Let them sneer, they are amusing, in their obscurantism. This was always the answer of those who wanted to understand nothing new, in the last ten million years. But the rise of advanced animals is the rise of under-standing. Standing under the appearances of the universe. It is a case where we have to understand what understanding means. 

Giant Galaxy, 1,000 times brighter than Milky Way, ten billion year old, discovered July 2017. It is seen as portions of ring from gravitational lensing by (I suppose) a galactic cluster in between…)

An incontrovertible mystery in physics is Dark Matter. Since the 1930s, we know that there is a massive contradiction between galaxies and gravity. (Between rotations and motions  of galaxies and the theory of gravity, more exactly; be it Newtonian, or its slight modification, Einsteinian gravity.)

So far, physicists have trained less and less conventional explanations of Dark Matter. My own SQPR (SubQuantum Patrice Reality), built to explain the Quantum, provides readily with an explanation of Dark Matter.  It’s completely out of the plane of conventional physics (if you condescend to consider Quantum Field Theory conventional…)

The Superfluid-Anyon model of Dark Matter (“SAD”) supposes that there is a type of particle (anyon) with a strong self-interaction, making a superfluid. In my own theory, SQPR, none of this is supposed.

Some will sneer that I suppose the existence of some properties which give rise to Quantum Physics, and this is what SQPR is. Didn’t Newton, assuredly a greater creature, proclaimed he didn’t make up hypotheses? Right. (Actually the Universal Attraction law was not hypothesized by Newton but by French astronomer Ishmael Bullialdus. So easy for Newton to say; Newton also hypothesized that light consisted of particles, and that he had proven strict equivalence between Kepler’s law and mechanics plus gravity…)

However, to under-stand Quantum Physics, to stand under it, one will have to suppose new, underlying hypotheses explaining the physics of the Quantum. If fundamental, paradigm shifting progress in physics is possible, this is how it will happen.

The leaner those hypotheses, the better. The heliocentric theory of planets’ orbits made FEWER hypotheses than those who believe “heavenly bodies” were special. Why so special? How special? The natural thing

An enormous meteorite, streaked through the skies in a fiery manner, and landed in Northern Greece. It was visited for centuries. Clearly space was full of rocks, no crystal balls…  

Considering other evidences (distance of the sun, computed to be large, thus the sun, enormous), the heliocentric theory was most natural.

Dark Matter may well be the equivalent of that theory. My own SQPR predicts a slow apparition, and built-up of Dark Matter. The latest observations (2017) of Dark Matter and ancient galaxies show no Dark Matter say ten billion years ago.

SAD does not predict that: it predicts Super Fluid Anyon Dark Matter was always there.

Science does not just teach facts and how to organize them in theories. I also teaches what explanations are.

Ex-planation is generally viewed as meaning to spread out. But there is a more striking etymology: An explanation is how to get out (ex) of a plane. In other words, acquiring a further logical dimension.

There is no fundamental new dimension, logically speaking, by supposing one more type of elementary particle. But deducing observed facts from effects which go beyond Quantum Physics would be really a new dimension of logic.

I make hypotheses, but fewer. And they are more natural. That’s the key. When one thinks about it, it was more natural to suppose that, out there in the heavens, matter was as we knew it. Similarly, out there in the Quantum, it is more natural that interactions are as we know them: at finite speed, to preserve causality. This is the most fundamental intuition of SQPR: it supposes that the Quantum Interaction (because spooky action at a distance is still an interaction of some sort) has preserved that fundamental property we observe in all interactions…

By the way, some of the skeptical ones come around, and they sneer that all this science is a wild goose chase after a goose which does not exist. They are mistaken: we are chasing after ourselves. We are chasing after how we explain things.

Even attempted scientific explanation are real, and fruitful. Because scientific activity, even when mistaken, consists in chasing after how we could explain things.

Technical description of SAD from Theory of Dark Matter Superfluidity:

…”a novel theory of DM superfluidity that reconciles the stunning success of MOND (MOdified Newtonian Dynamics) on galactic scales with the triumph of the ΛCDM (Cold Dark Matter) model on cosmological scales (where MOND fails miserably: MOND modifies gravity at some specific distance, way too small for galactic clusters; whereas ΛCDM leaves gravity alone, just adding mass, lots of mass, mass by a factor of ten…).

In the SAD model, the Dark Matter component consists of self-interacting axion-like particles which are generated out-of-equilibrium and remain decoupled from baryons throughout the history of the universe. Provided that its mass is sufficiently light and its self-interactions sufficiently strong, the DM can thermalize and form a superfluid in galaxies, with critical temperature of order ∼mK. The superfluid phonon excitations are assumed to be described by a MOND-like action and mediate a MONDian acceleration on baryonic matter. Superfluidity only occurs at sufficiently low temperature, or equivalently within sufficiently low-mass objects…

 

DARK MATTER EMERGENCE! (If so, is a New Quantum revolution at hand?)

March 31, 2017

Long story short: My own theory of Dark Matter predicts that Dark Matter is EMERGENT. That could be viewed as a huge flaw, easy to disprove, sending me back to a burrow somewhere to pursue my humble subterranean existence of sorts. HOWEVER, big surprise: DARK MATTER EMERGENCE seems to be exactly what was just observed in 2017, at the European Southern Observatory (ESO)!

***

Anomalies in the behavior of gravitation at a galactic scale, has become the greatest crisis in physics. Ever:

What is the problem? Four centuries of physics possibly standing on its head! (Using the virial theorem,) Swiss astronomer Fritz Zwicky discovered and named Dark Matter, or, as Zwicky said in German,  “dunkle Materie“, in 1933. Zwicky observed an enormously mysterious gravitational pull.

Zwicky computed that the observed gravitational pull did not correspond to the visible matter, by an ORDER OF MAGNITUDE, and thus Zwicky assumed that there was plenty of matter that could not be seen. (At the time, physicists scoffed, and went to stuff more interesting to the military, thus, better esteemed and more propitious to glorious splurging and handshakes from political leaders!)

If spiral galaxies were only made up of the matter that we can see, stars at the outer edge should orbit the centre slower than those closer to the center.. But Zwicky  noticed that this was not the case: all the stars in the Andromeda galaxy move at similar speeds, regardless of their distance from the galactic center. (For nationalistic reasons Americans love to attribute DM’s discovery to American astronomers Vera Rubin and Kent Ford .in the 1970s. However great Vera Rubin is, that’s despicable: they worked 40 years after Zwicky.)

Many studies since the 1930s provided evidence for Dark Matter. Such matter doesn’t interact with light, that’s why it is dark. Thus, one can only observe the effects of Dark Matter via its gravitational effects.

Nobel Prizes Were Only Given To the 5% So Far. The 5% Are All What Today’s Official Physics Is About. This Is One Of The Reasons Why I Am Thinking Outside Of Their 5% Box…

***

How does one compute the mass of a galaxy?

One just look at how many stars it has. (In the Solar System, the sun is a thousand times more massive than all the planets combined; studies on how much stars are moved by the planets around them confirm that most of the mass is in the stars.) And that shows up as the overall light emitted by a galaxy. Summing up the observed light sums up the mass. Or, at least that was the long-standing idea. (More recently, the pull gravitation exerts on light has been used to detect Dark Matter, and it has been used on a… massive scale!) 

At the scale of galaxies, or galactic clusters, the motions of objects is indicating at least ten times the gravitational force that should be there, according to gravitation theory, considering the mass we see (that is the mass of all the stars we see).

Problem: that would mean that he so-called “Standard Model” of physics has no explanation for most of the mass in the galactic clusters.

Reality check: the celebrities of physics are very arrogant, and think they know exactly what the universe had for breakfast, 13.8 billion years ago, and how big it was (never mind that their logic is ridiculously flawed). Up to a few years ago, many were in denial that they were missing most of the mass-energy in the universe with their Standard Model theory. 

However, here they are now, having to admit they missed 95.1&% of the mass-energy in the universe (according to their own latest estimates)!

A low logical cost solution to the riddle of the apparently missing mass, was to decree that all physicists who have studied gravitation since Bullialdus, nearly four centuries ago, got it wrong, and that gravitation is not, after all, an inverse square of the distance law. A problem is that French astronomer Bullaldius’ very elementary reasoning seems still to have kept some validity today. Remember that, in the Quantum Field Theory setting, forces are supposedly due to (virtual) particle exchanges? Well, that was the basic picture Bullialdus had in mind! (Thus those who want to modify so-called “Newtonian Dynamics” wreck the basic particle exchange model!)

***

Bullialdus’ Inverse Distance Squared Law, Basic to Newton-Einstein:

Ismael Boulliau (aka Bullialdus) a famous astronomer, member of the English Royal Society, proposed the inverse square law for gravity, a generation before Newton. (Bullialdus crater on the Moon, named for Boulliau, would have water, by the way.) Boulliau reasoned that the force would come from particles emitted by the sun, just like light. Here is Bullialdus voice:

“As for the power by which the Sun seizes or holds the planets, and which, being corporeal, functions in the manner of hands, it is emitted in straight lines throughout the whole extent of the world… seeing that it is corporeal, it becomes weaker and attenuated at a greater distance or interval, and the ratio of its decrease in strength is the same as in the case of light, namely, the duplicate proportion, but inversely, of the distances that is, 1/d².”

Why still true today? The carrier of force are particles.If they go to infinite distance (as electromagnetism and gravitation do), then the density of filed carriers (photons, gravitons) will go down, as Bullialdus said, for the reason he gave.

Bullaldius’ observation is the basis of Newton’s gravitation theory, which is itself the first order approximation of Einstein’s theory of gravitation. (Einstein’s gravitaion is a tweak on Newton’s theory; what Einstein did is actually to re-activate Buridan’s inertial theory with advanced mathematics invented by others (Riemann, Ricci, Hilbert, Levi-Civitta)

There is a basic problem here: although Einstein’s theory is a small tweak on Newton’s, MONDs are not. Correcting a theory by a factor of ten, a hundred, or a thousand is no tweak. Moreover: 

The ESO (European Southern Observatory) observation, illustrated above by ESO itself, seems to condemn BOTH of the two known, “official”classes of solutions for the gravitation problem: LCDM Dark Matter and Mond. The only theory left standing is my own Sub Quantic Dark Matter theory, which is fully emergent.

2017 ESO Discovery: Slowly Spinning Old Galaxies:Natascha Förster Schreiber at the Max Planck Institute for Extraterrestrial Physics in Germany and her colleagues have used the European Very Large Telescope in Chile to make the most detailed observations so far of the movement of six giant galactic discs, 10 billion years ago.

They found that, unlike in (quasi-)contemporary galaxies, the stars at the edges of these galaxies long ago, far away, move more slowly than those closer in.

“This tells us that at early stages of galaxy formation, the relative distribution of the normal matter and the dark matter was significantly different from what it is today,” says Förster Schreiber. (Well, maybe. MY interpretation would be very different! No DM!)

In order to check their unexpected results, the researchers used a “stack” of 101 images of other early galaxies to find an average picture of their rotations. The stacked galaxies matched the rotations of the more rigorously studied ones. “We’re not just looking at six weirdo galaxies – this could be more common,” says Förster Schreiber. “For me, that was the wow moment.”

***

MOdified Newtonian Dynamics (MONDs) Don’t Work:

About 10 billion years ago, there was a peak formation period of galaxies. By looking 10 billion light years away, one can see what was going on then, and have plenty of galaxies to look at. Where was the Dark Matter there? Was there Dark Matter then? One can answer these questions by just looking, because Dark Matter shows up in the way galaxies rotate, or orbit (in galactic cluster).

The result is both completely unexpected and spectacular! I am thrilled by it, because what is observed to happen is exactly the main prediction of MY theory of Dark Matter!

What is found is that, ten billion years ago, the largest star-forming galaxies were dominated by normal matter, not by the dark matter that’s so influential in galaxies today. (I reckon that this result was already indicated by the existence of galaxies which are mostly Dark Matter… at least in my sort of cosmology which differs massively from the standard Lambda Cold Dark Matter, LCDM model.)

MOND theories, relativistic or not, say that gravity is ten times stronger at, say, 30,000 light years away from a mass. If that’s the true law of gravitation in the last few hundreds of millions of years (as observed in presently surrounding galaxies), it should have been the case ten billion years ago. But that’s not what’s observed. So MOND theories can’t be true

***

LCDM cop-out: Dark Matter makes halos, like around the Virgin Mary’s Head!

On the face of it, the discovery about those ten billion year old galaxies say that the galactic disks then did not contain Dark Matter. That seems to me that it shoots down both MOND theories and the LCDM model (that’s the fancy name for the conventional Big Bang, latest version).

However, conventional scientists, and, in particular, cosmologists, are good at pirouettes, that’s why they are professionals.  There is still a (twisted) logical escape for LCDM model. The differences in early galaxies’ rotations demonstrates that there is very little Dark Matter in towards the middle of their disks, to start with, reason the Cold Dark Matter specialists. Instead, those ancient galaxies’ disks are almost entirely made up of the matter we see as stars and gas. The further away (and thus earlier in cosmic history) the galaxies were, the less dark matter their disks contained.

The specialists suggest that the turbulent gas in early galaxies condensed into the flat, rotating disk shapes we see today more quickly than Dark Matter, which remained in a diffuse  “halo”, which would progressively fall in… but had not started to falling enough, ten billion years ago. (That’s weird, because I thought LCDM mixed normal matter and dark matter, right from the start. In any case, I am not going to make their increasingly fishy case for them!).

Dark Matter gathers – but it takes time. This is exactly what my theory of Dark Matter predicts. In my own theory, Dark Matter is the result, the debris, of Quantum Interactions (entanglement resolutions, singularization) at very large distances. This debris gathering takes time.

My Dark Matter theory predicts that Dark Matter is an Emergent phenomenon. No other theory does that. Studies of more than 100 old giant galaxies support my theory, why making the situation (very) difficult for the conventional Dark Matter theory (“LCDM”) and impossible for the MOND theories.

This progressive build-up  of Dark Matter is NOT predicted by the other two Dark Matter theories. The standard (LCDM) cosmological Dark Matter model does NOT predict a slow gathering of Dark Matter. Nor does the  MOdified Newtonian Dynamics theories (MOND, relativistic or not) predict a slow apparition of Dark Matter.m the center and most of the visible matter.

It has been taken for granted by the Dark Matter advocates that Dark Matter, a sort of non-standard standard matter, was in the universe from its legendary start, the Big Boom, aka, Big Bang,

This is an important step in trying to figure out how galaxies like the Milky Way and larger galaxies must have assembled,” says Mark Swinbank at Durham University. “Having a constraint on how early the gas and stars must have formed the discs and how well-mixed they were with dark matter is important to informing their evolution.”

Journal reference: Nature, DOI: 10.1038/nature21685

Right. Or maybe, as I speculate, for plenty of excellent reasons coming from logically far away, this is an indication that not Gravitation Theory, but Quantum Theory, is not correct. Oh, the Standard Model, too, is not correct. But we all already knew this…

Conclusion: If the ESO observation that Dark Matter was not present in large galactic disks, ten billion years ago, is correct, I cannot imagine how MOdified Newtonian Dynamics theories could survive. And I find highly implausible that LCDM would. All what is left standing, is my own theory, the apparent main flaw of which, is now turned into a spectacular prediction! DARK MATTER Appears SLOWLY as predicted by Patrice Ayme’s SUB-QUANTIC Model. (Wow!)

DARK MATTER PROPULSION Proposed

December 10, 2016

In  Sub-Quantum Patrice’s Reality (SQPR), Matter Waves are real (in Quantum Theory Copenhagen Interpretation (QTCI) the Matter Waves are just probability waves of… knowledge… hence the insistence that “it came from bit“). There has been no direct evidence that Matter Waves were real. So far. But times they are changing as the other one, Bob Dylan, a gifted yet not too deep singer who got his Nobel today, said.

Both Dark Matter and Dark Energy are consequences of SQPR. So: Observing both Dark Matter and Dark Energy constitute proofs of SQPR.

The prediction of the deviation of light by the Sun was twice with “General Relativity” than the one predicted in Newtonian Mechanics. The effect was minute, and detected only in grazing starlight, during Solar eclipse of 29 May 1919 (by the ultra famous British astronomer and physicist Eddington). Thus, as 95% of the universe matter-energy is from Dark Matter or Dark Energy, my prediction carries more weight.

SPQR also predict “fuel-less” production, in a variant of the effect which produces Dark Matter in SQPR (also called PSQR below):

How does Dark Matter create propulsion? Well, that it does is evident: just look at galactic clusters (more details another day). A Matter Wave will expand, until it singularizes. If it expands enough, it will become so big that it will lose a (smaller) piece of itself during re-singularization. That  piece is the Dark Matter.

Thus visualize this: take a cavity C, and bounce a Matter Wave around it (there is plenty of direct theoretical and experimental evidence that this can be arranged).

Make a hole H in the boundary of C (this is not different from the Black Body oven the consideration of which led Planck to discover the Quantum).

Some Dark Matter then escapes. By the hole. 

However, Dark Matter carries energy momentum (evidence from Galaxies, Galactic Clusters, etc.).

Hence a push. A Dark Matter push. (Notice: the Dark Matter is created inside the device, it doesn’t have to be “gathered”. DM propellant speed could be many times the speed of light, hence great efficiency…)

The (spectacular) effect has been apparently observed by NASA.

Does this violate Newton’s Third Law? (As it has been alleged.)

No. I actually just used Newton’s Third Law, the Action = Reaction law. So SQPR explains the observed effect in combination with the Action= Reaction Law, “proving” both.

How could we prove SQPR? There should be a decrease of energy-momentum after a while, and the decrease should equal the observed push exactly.

Warning: The preceding considerations are at the edge of plausible physics. (Groups of dissenting physicists are always busy making theories where Dark Matter does not exist (and they should!) Should they be right, the preceding is nonsense. The consensus, though, is that Dark Matter exists, but is explained by a variant of the so-called “Standard Model”, using “Supersymmetry”, or “WIMPs”, or “Axions”. My own theory, SQPR is, by far, the most exotic, as it uses an hypothesized Sub Quantic Reality, obtained by throwing Quantum Theory Copenhagen Interpretation, QTCI, through the window, as a first order theory.)
