Of God, Mice, And Men Who Believe They Created The Universe

February 8, 2018

When theists say that the universe exists because of God, they are saying that the universe exists, because of some agent they know: that make those theists vastly superior to us, simple miscreants, who do not happen to be acquainted with what, or who, created all and everything. Surely, those superior beings should lead us? So what sounds metaphysical, by asserting a “God” boils down to claiming a higher place in an all too human hierarchy.

Universe” means literally, “turned into one”, whereas “multiverse” would be: “turned into many”. So the set of all multiverses is the universe. (So the alleged existence of “multiverse” is akin to Bertrand Russell’s famous paradox of the set whose elements are not elements of itself; Russell’s paradox brought down mathematical logic as it had been known prior; present day physicists have been repeating that mistake, from lack of basic culture in the matter of mathematical logic!)

If we were to claim, and, or, even worse, have the feeling, that we know why the universe exists, we would be claiming, or have the impression, that we were God. This is not the business of physics, only the business of those who want us to be guided by absolutism.

Alexander the Great, seeing his blood flow, asked himself that question: am I a God? His Greek and Macedonian companions laughed him off. Later, on the advice of his mom, Olympia, Alexander ordered the old, most senior generalissimo Antipater, a companion of Alexander’s father, from Greece to Babylon. Antipater refused to obey. Antipater’s youngest son was Alexander’s page. Alexander found himself ceasing to be, before he could even organize his affairs.

We are both everything and nothing relative to the universe. The key to wisdom, is to keep a balance.

Man, playing God, touches man, playing Adam. All very touching, self-obsessing, self-gratifying, self-glorifying mental, self-stimulation, and self-mutilation.

The universe is, what it is. Science can describe it, not explain how it came to be. That is the proper mood that wisdom should embrace. Embracing the humility of reality, so we can unleash the power of truth.

Let theologians, dinosaurian conservatives, the Politically Correct and the Perfect Cretins, among others, try to learn this: We have to embrace the way things are, before we can hope to change what needs to be changed. And there is plenty of the latter. So stop claiming some human beings know why there is all there is. They don’t. They, and, or, their supporters just want everything you could possibly imagine, and then more.

Note 1: the comment above was an answer to: “Why Is There Something, Rather Than Nothing?
Posted on February 8, 2018 by Sean Carroll
A good question!

Or is it?”

In it, Sean points out notions which I have exposed in the past, but are worth repeating, as many physicists, let alone philosophers and theologians, don’t get them. First of all Sean basically points out that the universe just is (as I said above, by definition of this neuronal activity!). And secondly Sean Carroll, a famous Cal Tech cosmologist, points out that all too many professional physicists don’t even understand that physics, as presently understood, doesn’t explain the universe! In other words, as I have said for decades, all too many physicists take themselves for God! (That is in the same meta category as Niels Bohr’s famous retort to Albert Einstein:”Stop telling God what to do!“)

“The right question to ask isn’t “Why did this happen?”, but “Could this have happened in accordance with the laws of physics?” As far as the universe and our current knowledge of the laws of physics is concerned, the answer is a resounding “Yes.” The demand for something more — a reason why the universe exists at all — is a relic piece of metaphysical baggage we would be better off to discard.

This perspective gets pushback from two different sides. On the one hand we have theists, who believe that they can answer why the universe exists, and the answer is God. As we all know, this raises the question of why God exists; but aha, say the theists, that’s different, because God necessarily exists, unlike the universe which could plausibly have not. The problem with that is that nothing exists necessarily, so the move is pretty obviously a cheat. I didn’t have a lot of room in the paper to discuss this in detail (in what after all was meant as a contribution to a volume on the philosophy of physics, not the philosophy of religion), but the basic idea is there. Whether or not you want to invoke God, you will be left with certain features of reality that have to be explained by “and that’s just the way it is.” (Theism could possibly offer a better account of the nature of reality than naturalism — that’s a different question — but it doesn’t let you wiggle out of positing some brute facts about what exists.)

The other side are those scientists who think that modern physics explains why the universe exists. It doesn’t! One purported answer — “because Nothing is unstable” — was never even supposed to explain why the universe exists; it was suggested by Frank Wilczek as a way of explaining why there is more matter than antimatter. But any such line of reasoning has to start by assuming a certain set of laws of physics in the first place. Why is there even a universe that obeys those laws? This, I argue, is not a question to which science is ever going to provide a snappy and convincing answer. The right response is “that’s just the way things are.” It’s up to us as a species to cultivate the intellectual maturity to accept that some questions don’t have the kinds of answers that are designed to make us feel satisfied.”

Note 2: Swiss citizen Tariq Ramadan, the world’s most famous  Islamist propagandist, holder of two chairs (no less!) at Oxford University, and now in a French prison, was going around the world grievously beating and raping women. Why? Because, precisely, he wanted everything, and that included beating up handicapped women. Even now, as he sits in prison, he enjoys his power: immensely powerful organizations behind him, the sort who made him an Oxford Don, are threatening many more women, who also want to file complaints against Ramadan, but are afraid to do so. The human species is naturally metaphysical. Ramadan wanted to create a universe where he and his ilk could hurt and terrorize women at will. This is not any different from telling us that Muhammad flew to Jerusalem, the capital of Israel, on a winged horse: it is outrageous, but it creates a universe, and its cause (and in this case Islamists are the cause of said universe!)

QUANTUM FLUCTUATIONS & ARROW OF TIME

January 18, 2016

What is time? Quantum Physics gives an answer, classical physics does not. Quantum Physics suggests that time is the set of all irreversible processes. This is a world first, so it requires some explanations. I have been thinking, hard, of these things all my life. Sean Carroll, bless his soul, called my attention to the new development that mainstream physicists are starting to pay attention to my little kingdom(so I thank him).

***

SCIENCE IS WHAT WE DO:

Sean Carroll in “Quantum Fluctuations”:

“Let’s conjure some science up in here. Science is good for the soul.”

Patrice Ayme’: Why is science good for the soul? Because the human soul is centered on finding truth. Science is truth, thus science is human. Nothing is more human than science. Science is what humans do. Another thing humans do is art, and it tries to both duplicate, distort, and invent new nature, or interpretations, interpolations, and suggestions, of and from, nature:

Claim: Quantum Interference Is An Irreversible Process, Time's Arrows All Over. Quantum Interference Goes From Several Waves, To One Geometry. Soap Bubbles Brim With Quantum Interference..

Claim: Quantum Interference Is An Irreversible Process, Time’s Arrows All Over. Quantum Interference Goes From Several Waves, To One Geometry. Soap Bubbles Brim With Quantum Interference..

SC: …what are “quantum fluctuations,” anyway? Talk about quantum fluctuations can be vague. There are really 3 different types of fluctuations: Boltzmann, Vacuum, & Measurement. Boltzmann Fluctuations are basically classical: random motions of things lead to unlikely events, even in equilibrium.

Patrice Ayme’: As we will see, or we have already seen in my own “Quantum Wave”, Quantum Fluctuations are just the Quantum Waves. Richard Feynman, at the end of his chapter on entropy in the Feynman Lectures on Physics, ponders how to get an arrow of time in a universe governed by time-symmetric underlying laws. Feynman:

“So far as we know, all the fundamental laws of physics, such as Newton’s equations, are reversible. Then where does irreversibility come from? It comes from order going to disorder, but we do not understand this until we know the origin of the order. Why is it that the situations we find ourselves in every day are always out of equilibrium?”

Patrice Ayme’: Is that really true? Are equations time-symmetric? Not really. First, equations don’t stand alone. Differential equations depend upon initial conditions. Obviously, even if the equations are time-symmetric, the initial conditions are not: the final state cannot be exchanged with the initial state.

Quantum Physics make this observation even more important. The generic Quantum set-up depends upon a geometric space S in which the equation(s) of motion will evolve. Take for example the 2-slit: the space one considers generally, S, is the space AFTER the 2-slit. The one before the 2-slit, C, (for coherence) is generally ignored. S is ordered by Quantum interference.

The full situation is made of: (C, S & Quantum interference). it’s not symmetric. The Quantum depends upon the space (it could be a so-called “phase space”) in which it deploys. That makes it time-assymmetric. An example: the Casimir Effect.

***

QUANTUM PHYSICS IS ABOUT WAVES:

Sean Carroll: “Nothing actually “fluctuates” in vacuum fluctuations! The system can be perfectly static. Just that quantum states are more spread out.”

Indeed. Quantum states are, intrinsically, more spread out. They are NON-LOCAL. Why?

One has to go back to the basics. What is Quantum Physics about? Some, mostly the “Copenhagen Interpretation” followers, claim Quantum Physics is a subset of functional analysis. (The famous mathematician Von Neumann, one of the creators of Functional Analysis, was the founder of this system of thought; this scion of plutocrats, famously, yet satanically, claimed that De Broglie and Bohmian mechanics were impossible… Von Neumann had made a logical mistake; maybe that had to do with being involved with the satanic part of the American establishment, as, by then, that Hungarian had migrated to the USA and wanted to be called “Johnny”!).

The Quantum-as-functional analysis school became dominant. It had great successes in the past. It allows to view Quantum Physics as “Non Commutative Geometry”. However, contrarily to repute, it’s not the most fundamental view. (I have my own approach, which eschews Functional Analysis.)

But let’s backtrack. Where does Quantum-as-functional-analysis come from? A Quantum system is made of a (“configuration”) space S and an equation E (which is a Partial Differential Equation). Out of S and E is created a Hilbert Space with a basis, the “eigenstates”.

In practice, the eigenstates are fundamental waves. They can be clearly seen, with the mind’s eye, in the case of the Casimir Effect with two metallic plates: there is a maximal size for the electromagnetic wavelengths between the plates (as they have to zero out where they touch the metal).

The notion of wave is more general than the notion of eigenstate (Dirac pushed, successfully, the notion of wave so far that it created space, Spinor Space, and Quantum Field Theory has done more of the same, extending the general mood of De Broglie-Dirac to ever fancier Lagrangians, energy expression guiding the waves according to De Broglie scheme).

Historically, De Broglie suggested in 1923 (several publications to the French Academy of Science) that to each particle was associated a (relativistic) wave. De Broglie’s reasons were looked at by Einstein, who was impressed (few, aside from Einstein could understand what De Broglie said; actually De Broglie French jury thesis, which had two Nobel prizes, was so baffled by De Broglie’s thesis, that they sent it to Einstein, to ask him what he thought. Einstein replied with the greatest compliment he ever made to anyone: “De Broglie has started to lift the great veil,” etc…).

The De Broglie’s wave appears on page 111 of De Broglie’s 1924 thesis, which has 118 pages (and contains, among other things, the Schrödinger wave equation, and, of course, the uncertainty principle, something obvious: De Broglie said all particles were guided by waves whose wavelengths depended upon their (relativistic) energy. An uncertainty automatically appears when one tries to localize a particle (that is, a wave) with another particle (that is, another wave!)

***

CLASSICAL PHYSICS HAS NO ARROW OF TIME:

Consider an empty space S. If the space S is made available to (classical) Boltzmann particles, S is progressively invaded by (classical) particles occupying ever more states.

Classical physicist (Boltzmann, etc.) postulated the Second Law of Thermodynamics: something called entropy augmented during any process. Problem, rather drastic: all classical laws of physics are reversible! So, how can reversible physics generate a time-irreversible law? Classical physicist have found no answer. But I did, knight in shining armor, mounted on my powerful Quantum Monster:

***

QUANTUM PROCESSES CREATE IRREVERSIBLE GEOMETRIES:

When the same space S is made available as part of a Quantum System, the situation is strikingly different. As Sean Carroll points out, the situation is immediately static, it provides an order (as Bohm insisted it did). The observation is not new: the De Broglie waves provided an immediate explanation of the stability of electronic waves around atoms (thus supporting Bohr’s “First, or Semi-Classical, Quantum Theory”.

What’s a difference of a Quantum System with a classical system? The classical system evolves, from a given order, to one, more disordered. The Quantum system does not evolve through increasing disorder. Instead, the space S, once accessed, becomes not so  much an initial condition, but a global order.

The afore-mentioned Hilbert Space with its eigenstates is that implicit, or implicate (Bohm) order. So the Quantum System is static in an important sense (from standing Quantum Waves, it sorts of vibrates through time).

Thus Quantum Systems have an intrinsic time-assymmetry (at least when dealing with cavities). When there are no cavities, entanglement causes assymmetry: once an interaction has happened, until observation, there is entanglement. Before interaction, there was no entanglement. Two classical billiards balls are not entangled either before or after they interact, so the interaction by collision is fully time reversible.

Entanglement is also something waves exhibit, once they have interacted and not before, which classical particles are deprived of.

Once more we see the power of the Quantum mindset for explaining the world in a much more correct, much simpler, and thus much more powerful way. The Quantum even decides what time is.

So far as we know, all the classical fundamental laws of physics, such as Newton’s equations, are reversible. Then were does irreversibility come from? It does NOT come, as was previously suggested, from order going to disorder.

Quite the opposite: irreversibility comes from disorder (several waves)going to order (one wave, ordered by its surrounding geometry). And we do understand the origin of the order: it’s the implicit order of Quantum Waves deployed.

You want to know the world? Let me introduce you to the Quantum, a concept of wealth, taste and intelligence.

Last and not least: if I am right, the Quantum brings the spontaneous apparition of order, the exact opposite picture which has constituted the manger in which the great cows of physics have found their sustenance. Hence the fact that life and many other complicated naturally occurring physical systems are observed to create order in the universe are not so baffling anymore. Yes, they violate the Second Law of Thermodynamics. However, fundamentally, that violated the spirit, the principle of the universe, the Quantum itself.

Non-Conservation Of Energy & Multiverse Madness

February 22, 2015

Before unreason took over physics, one of the major principles was energy conservation. However, this was before. Now Sean Carroll, following other Multiversists (as I call them insolently) crucially depend upon nonconservation of energy.

Sean wrote an article, short and to the point: “Energy is not conserved.

Well written, indeed. Carroll glibly asserts that “see, it was not so hard” (to throw away the most fundamental principle of physics, energy conservation).

Galactic Cluster Focuses Blue Galaxy Light

Galactic Cluster Focuses Blue Galaxy Light

All the blue blotches are images of a far-away galaxy, which are focused by the cluster of galaxies in front. By the way, both Newtonian Theory and Einstein Theory predict the deviation of light by matter (more so with Einstein, as time slows down, allowing for more time to deviate).

The Universe we have, and can see, is so immense, we can’t comprehend it. There is no need to claim there are more of them than atoms. Except if there is a need to go completely crazy (something Putin and other plutocrats are all for!)

That energy is NOT conserved is essential to enable the creation of universes at the drop of a hat.

Nothing is really true anymore, even energy is not conserved. It costs nothing to create a universe.

Next we will all be led to believe plutocrats create not just jobs, but universes.

It’s probably related. Thanks, Sean.

So take two galaxies clusters, G1 and G2. Suppose they separate from the expansion of the universe. Sean Carroll, following the Multiverse fashion, asserts that it cost no energy to separate said galaxies.

Then he has a photon P travelling from G1 to G2, and he sees it has lost energy, so energy is not conserved. Multiversists repeat this argument ad nauseam.

In truth, what they stumbled upon is that the definition of mass-energy in the Theory of Gravitation is not clear. That’s all. The difficulty has been known for generations of mathematicians (behind closed doors). However, it does not mean that physics reduces to dust.

It just means one has to go back to Riemann’s intuition of the 1860s, and reconsider it carefully. Riemann tried to reduce force to geodesic separation. I would suggest to reduce energy to a function related to geodesics density. As geodesics separate, energy is put in the system. With this notion, the fact that it costs nothing to create a universe disappear. https://patriceayme.wordpress.com/2013/08/08/quantum-trumps-spacetime/

Physicists can’t reduce the universe just to physics, physics has to reduce to mathematics, too, at least in part.

One may wonder what the Multiversists reduce physics to. Apparently, having done away with energy conservation, a fundamental axiom, they replace it by universe creation. They reduce all of physics to the creation of universes.

Dark Energy, the accelerated expansion of the universe, questions the entire scheme of present day cosmology, let alone physics. Starting the conversation (logos) by throwing out the most sacred principle of physics (energy conservation), and replacing it with instant karma is as glib as glib gets.

Instant karma? Thanks to the alleged non-conservation of energy, the creation of trillions of universes per second per cubic meter is eminently reasonable.

Does that makes Middle –Age theology sitting angels on pinheads a plausible outcome? This is reductio ad absurdum, if I ever saw it.

Quantum Field Theorists may smirk, and accuse me of not knowing that energy is not conserved in QFT

The time-energy uncertainty relation seems indeed to allow for large energy excursions, if they happened in a short time. But that’s related to “virtual particles”, which admittedly are neither virtual, nor particles… Just resting on that would allow a universe in a length of time so short it has no meaning (because it has no clock).

Agreed, physics is hard. Agreed, today’s “Standard Model” of High Energy Physics explains only 4% of the universe.

But that’s no excuse to go crazy, and see gazillion universes on every pinhead.

That only help the crazies.

Crazy like foxes, crazy like plutocrats.

MULTIVERSE IDIOCY DISSECTED

August 2, 2014

Physicist Sean Carroll, “explaining why the many-worlds approach is not completely insane“, says: “If the particle can be in a superposition of two states, then so can the apparatus.”

This fundamental error, that everything is a superposition of states, is the essence of the idiocy of the Many World and Multiverse error.

Why Mr. Physicist Carroll? Why is it that, for you, if something is a superposition of two possibilities, then so can be something else? Where is the logic in that? There is none whatsoever. Let me show you why. Why that’s illogical.

Maybe, sometimes, because something can be cut in two, say a fish, another fish can be cut in two, or a million fishes can be cut in two, indeed.

The fact that fishes can be cut in two, because one fish can be cut in two, does not imply that everything else can be cut in two.

For example, the fact that one can cut fishes in two does not imply that the sea can be cut in two. Such is the Multiverse error, a very fishy argument.

Quantum Dot: Fuzzy, Not Discrete!

Quantum Dot: Fuzzy, Not Discrete!

Transmission Electron Microscope Image of a single InAsP/InP Quantum dot (left; “In” is for Indium); such dots exhibit discrete electronic energy levels (Right Top), and this allows, upon spatial and spectral filtering, the generation of single photons on demand (Right bottom).

That some process can result ultimately in two states, does not mean that the sea, or anything else, will be a “superposition of two states”.

When we mention “the particle” (whatever that is) and the apparatus (whatever that is) we are talking here about things of completely different natures, obviously.

What’s the difference? Or differences?

Obviously, “the particle” is being measured. And it’s measured by “the apparatus”.

One is “Quantum”, “the particle”. The other is classical, the “apparatus”.

What’s the most basic difference between “Quantum” and “Classical”? “Quantum” is dominated by DISCRETE states. “DISCRETE” here is in the strict mathematical sense (in bijection with a subset of the natural numbers, N).

Discreteness of light emission is how Planck explained the Blackbody Radiation and resolved the Ultra Violet Catastrophe.(1900 CE)

Discreteness of light reception is how Einstein explained the Photoelectric effect. (1905 CE.)

Discreteness of electronic orbitals is Bohr explained the structure of atoms. (1912 CE.)

Discreteness of non-self-interfering-to-destruction waves is how De Broglie explained all the subjacent discreteness, uncertainty, interference and basic dynamics. (1923.)

Classical mechanics is NOT discrete. We do not understand why. It’s a major mystery.

But the passage from Quantum to Classical has been studied experimentally in simple, particular (namely made of PARTICLES) systems.

Let’s go back to Sean’s statement:

“If the particle can be in a superposition of two states, then so can the apparatus.”

I just said that “Quantum” is characterized, as its name indicates, by discreteness, a superposition of states.

In other words, in Sean’s view the foundation of the Many World Interpretation/Multiverse theory is that Quantum = Classical.

Yet, the very concept of “Science” comes from the ability of scindere, to cut in two, to make distinctions.

By ignoring the most basic distinction, that between Quantum and Classical, the Many Worlds/Multiverse theory reveals itself to not be science.

Yet, it’s even worse than that. The Multiverse error is reminiscent of the blind alley of the Epicycle theory of Ptolemy and company, 2,000 years ago.

Patrice Ayme’

Notes: 1) The error was inaugurated by Everret, a student of Wheeler, 1963 CE. At the time it was viewed as horrendous (probably for the reasons above, but they were left unsaid; the preceding is my reasoning, entirely). Everret was driven out of research physics (although there were lots of jobs at the time).

2) Bohr and his followers had got the ball rolling, by murky attacks against reality itself. It was debatable at the time, as some then-not-discovered particles (say neutrinos) led to apparent violation of energy-momentum conservation.

3) The philosopher Heidegger, maybe inspired by some of the less wise, contemporaneous statements of Bohr and company, insisted that the distinction between “subject” and “object” be eradicated. Unsurprisingly, he soon became a major figure of Nazism, where he was able to apply himself to further lack of distinction.
