QUANTUM ENTANGLEMENTS MAKE TIME AN ARROW

May 19, 2017

Through Wave Collapse and the ensuing Entanglements it sometimes brings, QUANTUM PHYSICS CREATES A CAUSAL STRUCTURE, THROUGHOUT THE UNIVERSE, THUS, AN ARROW OF TIME.

Actually it’s more than a simple causal structure: it is an existential structure, as localization creates materialization, in the (Sub-)Quantum Theory I advocate. (It’s a theory where there are no dead-and-alive cats, but particles in flight are not particles… Contrarily to what Einstein thought, but more along the lines of Niels Bohr, horror of horrors…) It also means that time, at the smallest scale, is a nonlocal entanglement. This is not a weird new age poetry, but pretty much what the raw formalism of Quantum Physics say. I throw the challenge to any physicist to contradict this in any way. It’s completely obvious on the face of it.

You read it here first, as they say (although I may have said it before). Is time absolute? How could time be absolute? Where does the Arrow Of Time (Eddington) come from? Is there something else which grows with time?

The old answer is entropy, traditionally denoted by S.

Boltzmann’s equation S = k log P says that entropy augments during the evolution of a system. P indicates the number of states accessible by the system. Entropy was a construction from later Nineteenth Century physics, a successful attempt to understand the basic laws of thermodynamics (mostly due to Carnot).

A big problem for classical thermodynamics: what’s a state? That’s not clear.

However Quantum Physics define states, very precisely. However, very specifically: a situation, defined in space-time, what Bohr and Al. called an “experiment” (rightly so!) defines a number of possible outcomes: the latter become the “states”, a basis for the Hilbert Space the “experiment” defines.

Classical statistical mechanics does not enjoy such precisely defined states. So why not to use the states of Quantum Physics? Some could object that Quantum “experiments” are set-up by people. However Quantum Interactions happen all the time, independently of people. As in the Quantum experiments set-up by people, those Quantum Interactions grow something: Quantum Entanglement. ( Self-described “Quantum Mechanic” Seth Lloyd from MIT has also mentioned that entanglement and the arrow of time could be related.)

Quantum Entanglement has a direction: from where singularization (= localization = the collapse of the Quantum wave packet) happened first, to the distant place it creates the geometry of (yes, entanglement creates geometry, that’s why it’s so baffling to specialists!) 

Quantum Physics, Or, More Precisely, What I call QUANTUM INTERACTIONS are irreversible processes. Hence the Arrow Of Time

So we have two things which grow, and can’t be reversed: Time and Wave Collapse/Quantum Entanglement. I propose to identify them. (After all, Maxwell proposed to identify electromagnetic waves and light, just because they are both waves and went at the same speed; it turned out to be a magnificent insight.)

Quantum Wave function collapse is time irreversible (actually, the entire Quantum Wave deployment is time irreversible, because it depends only upon the geometry it’s deployed in). The mechanism of wave function collapse is philosophically a matter of often obscure interpretations, and arguably the greatest problem in physics and philosophy.

My position here is perfectly coherent: I believe the Quantum Waves are real. (So I do not believe the waves are waves of ignorance, and an artefact, as some partisans of Quantum decoherence have it). Those objective waves are real, although not always in one piece (that’s how I generate Cold Dark Matter).

By the way, it is the collapse of the Quantum Wave which “creates” the Quantum Entanglement At least that’s how the mathematics, the description of the theory has it! The picture it creates in one’s mind (first the wave, then the collapse, then the entanglement) makes sense. Actually I am arguing that this is how sense makes sense!

Quantum Entanglement is a proven experimental fact. All physicists have to agree with that. Thus the Quantum Wave has to be real, as it is the cause of the Quantum Entanglement! (I am pointing out here that those, and that’s now nearly all of them, who believe in Entanglement are incoherent if they don’t believe in the wave too!).

Jules Henri Poincaré had seen that time and space were not equivalent. That was meritorious, as Poincaré had proposed the original ideas of “local time” and “local space” theories, which are the fundamental backbones of Special Relativity (they are deduced from the constancy of the speed of light).

Even Einstein publicly frowned on the concept of “spacetime”, which identifies space and time; “spacetime” was proposed by Minkowski, Einstein’s own professor at the EHT… They may not have been friends, as Minkowski compared Einstein to a “lazy dog”; Einstein, of course, respected Poincaré so much, that he grabbed the entire theory of Relativity from him, including its name…

Quantum Physics does not outright treat time as equivalent to space, quite the opposite (although Quantum Field theorists have tried to, and do treat space and “imaginary time” as the same!). In fundamental Quantum Physics, time is a one parameter group of transformation, not really a dimension.

When a glass falls and shatters, Classical Mechanics is at a loss:’Why can’t it reassemble itself, with as little work?” Classical Thermodynamics mumbles:’Because Entropy augments’. (That may be a tenable position, but one will have to count the states of the glass in a Quantum way. Even then, the full energy computation will reveal a lack of symmetry.)

I say, simply:’A glass which has shattered can’t be reassembled, because Quantum Interactions, and ensuing entanglements happen.’ The resulting topology of cause and effect is more complicated than what one started with, and can’t be reversed. Quantum Interactions and ensuing effects at a distance they provide with, create a partial, nonlocal, ordering of the universe. Time. (Once a set has been physically defined, it has been thoroughly interacted with, Quantum Mechanically, and then it becomes a “well ordering”!)

So what’s time? The causal structure of the universe as determined by irreversible, causal Quantum Wave collapse and Quantum Entanglement.

Poincaré: Local Time Implies Mass = Energy

March 29, 2016

Historically three functions were attributed to time: simultaneity, synchronization and duration. Time became important in physics even before Galileo analyzed how gravity could be diluted by using a slope. Middle Age mathematicians made the first differential calculus computations using time, two centuries before Fermat established calculus.

Newton used calculus for his detailed theory of gravitation. However Isaac thought his own theory made no sense. The problem was that gravity was supposed to act instantaneously at a distance. Isaac thought that it is inconceivable that inanimate Matter should, without the Mediation of something else, which is not material, operate upon, and affect other matter without mutual Contact…That Gravity should be innate, inherent and essential to Matter, so that one body may act upon another at a distance thro’ a Vacuum, without the Mediation of any thing else, by and through which their Action and Force may be conveyed from one to another, is to me so great an Absurdity that I believe no Man who has in philosophical Matters a competent Faculty of thinking can ever fall into it.”

Poincaré: Time Is Local, MASS = ENERGY, Yet Relativity Is Not Fully Relative

Poincaré: Time Is Local, MASS = ENERGY, Yet Relativity Is Not Fully Relative

[The picture actually alludes to a completely different work of Poincaré, his discovery that qualitative methods in non solvable differential equations produced results where exact differential equations a la Newton did not: in particular, Poincare’s recurrence theorem… Useful in astronomy.]

Newton’s theory depended crucially on an absolute, universal time: thus the gravity force vector could always point to the center of (the) mass (exerting the gravitational force).

However the wrapping up of the electromagnetic equations by Maxwell showed that light was electromagnetic field travelling at speed c. C was universal. And independent of any “rest frame”. After thinking about the problem for twenty years, Lorentz discovered that, for electromagnetic phenomena to stay the same in a moving frame, one had to introduce what Poincaré called a “Local Time”. Poincaré then pointed out that there was no absolute rest relative to an “ether”, all one could do was to analyze the motion of matter relative to matter.

Then Poincaré thought some more for five years, and published in 1900, in the major Dutch physics Journal, that electromagnetic field retardation and its violation of Newton’s Third Law (Action equals reaction) could be resolved by attributing the inertial mass E/cc to the electromagnetic field.

(Mass = energy was attributed to a number of second order German physicists for Francophobic and nationalistic reasons, and the notion is repeated to this day by ignorant parrots; that would be sort of funny, if it did not distort not just the history of physics, but even the understanding of physics, as the parrots tend to not have as deep an understanding the underlying concepts).

“The principle of relativity, according to which the laws of physical phenomena must be the same for a stationary observer as for one carried along in a uniform motion of translation, so that we have no means, and can have none, of determining whether or not we are being carried along in such a motion… From all these results, if they were to be confirmed, would issue a wholly new mechanics which would be characterized above all by this fact, that there could be no velocity greater than that of light, any more than a temperature below that of absolute zero. For an observer, participating himself in a motion of translation of which he has no suspicion, no apparent velocity could surpass that of light, and this would be a contradiction, unless one recalls the fact that this observer does not use the same sort of timepiece as that used by a stationary observer, but rather a watch giving the “local time.[..] Perhaps, too, we shall have to construct an entirely new mechanics that we only succeed in catching a glimpse of, where, inertia increasing with the velocity, the velocity of light would become an impassable limit. The ordinary mechanics, more simple, would remain a first approximation, since it would be true for velocities not too great, so that the old dynamics would still be found under the new” [Poincaré, 1904.]

So after Poincaré’s work, what was the situation? Time is local (yet clocks could be synchronized at a distance), Galilean relativity could be extended to electromagnetism as long as mass = energy.

Are we further along today?

Poincaré kept a distinction between “apparent time” and “ether” given time. Einstein’s variation of the theory does not preserve this distinction (and that makes it false, ha ha ha). I will not go into the details here, as it would be pure research of the sort that 99% of theoretical physicists are unwilling to consider (some other day, in simple words). I am not trying to spite Einstein, long my preferred physicist (no more, though, he has exhausted my patience with vindictive plagiarism, in particular against Poincaré and Karl Popper, let alone abandoning his little daughter). Actually Einstein admitted there was some sort of ether: …”we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether. According to the general theory of relativity space without ether is unthinkable.” [Einstein, 1920.]

But there is much worse: we now know that Quantum Physics ignores Local Time. Quantum Physics brings back the instantaneous interaction at a distance which repulsed Newton. (At least, it appears instantaneous experimentally, so far, and it is certainly instantaneous in the existing Quantum formalism, which, amusingly, is in the same exact situation as Newtonian Physics: the Quantum as we know it today, cannot function without that instantaneous Quantum Interaction.

Whatever happens next, only one thing is clear; those who claim physics has been figured out, know very little, and should be advised to shut up, lest their  egregious statements confuse the public about the scientific method.
