Could aether be the factor that integrates phenomena of quantum mechanics and general relativity, the observation of which would finally provide us with a realist interpretation akin to the one Einstein sought? Can experimental designs and instrumentation ever become advanced enough to register such a medium, and what does current physics suggest about the chances of this substrate existing? — Enrique
It looks as if all you have is yet another hidden variable theory, waving the word "aether" around.
Show how your proposal is compatible with Bell's inequality. — Banno
From what I've read, De Broglie wave theory is an intriguing model of what goes on inside the atom, but doesn't account for spooky action at a distance entanglement. — Enrique
The de Broglie–Bohm theory, also known as the pilot wave theory, Bohmian mechanics, Bohm's interpretation, and the causal interpretation, is an interpretation of quantum mechanics. In addition to the wavefunction, it also postulates an actual configuration of particles exists even when unobserved. The evolution over time of the configuration of all particles is defined by a guiding equation. The evolution of the wave function over time is given by the Schrödinger equation. The theory is named after Louis de Broglie (1892–1987) and David Bohm (1917–1992).
The theory is deterministic[1] and explicitly nonlocal: the velocity of any one particle depends on the value of the guiding equation, which depends on the configuration of all the particles under consideration.
Measurements are a particular case of quantum processes described by the theory and yields the standard quantum predictions generally associated with the Copenhagen interpretation. The theory does not have a "measurement problem", due to the fact that the particles have a definite configuration at all times. The Born rule in Broglie–Bohm theory is not a basic law. Rather, in this theory, the link between the probability density and the wave function has the status of a hypothesis, called the "quantum equilibrium hypothesis", which is additional to the basic principles governing the wave function.
The theory was historically developed in the 1920s by de Broglie, who, in 1927, was persuaded to abandon it in favour of the then-mainstream Copenhagen interpretation. David Bohm, dissatisfied with the prevailing orthodoxy, rediscovered de Broglie's pilot-wave theory in 1952. Bohm's suggestions were not then widely received, partly due to reasons unrelated to their content, such as Bohm's youthful communist affiliations.[2] The de Broglie–Bohm theory was widely deemed unacceptable by mainstream theorists, mostly because of its explicit non-locality. Bell's theorem (1964) was inspired by Bell's discovery of Bohm's work; he wondered whether the theory's obvious nonlocality could be eliminated. Since the 1990s, there has been renewed interest in formulating extensions to de Broglie–Bohm theory, attempting to reconcile it with special relativity and quantum field theory, besides other features such as spin or curved spatial geometries.[3] — Wiki
Apparently you've never read a book or taken a course on quantum mechanics or relativity theory. Probably haven't even talked about the subject much either. — Enrique
Are you just trying to get a rise out of me by insulting my post based on nothing? You shouldn't troll with contentless posts indicating you don't know anything about the subject being discussed, — Enrique
And what in the world is your definition of pseudoscience? You brandish the term a lot but don't really specify its meaning. — Enrique
The aether proposal explains why quantum entanglement can appear to transcend the speed of light while general relativity and nonlocal quantum mechanics still hold, — Enrique
Not really. Fundamentally speaking, the experiments you're describing are those for which QM predicts outcomes that violate Bell inequalities. They rule out precisely the types of theories that suggest Bell inequalities should hold; that is, classical realist local theories. But that does not suffice to verify nonlocality.Essentially, the statistical results of Bell's experiment rule out local hidden variables, a property of the particles themselves determining probabilistic outcome, verifying nonlocality in quantum mechanics. — Enrique
Tossing this in:The delayed choice experiment which developed out of Einstein's EPR paradox paper seems to contradict nonlocal hidden variables of a kind consistent with relativity unless viewing the detectors as separate reference frames, and this doesn't explain anything beyond correcting some calculative imprecision between clocks etc., basically not a realist account. — Enrique
I'm not sure I understand how it does this. Bob has a clock. Alice has a clock. Alice takes a very long trip; once she is a light year away, she sets up a station. Bob generates two electrons whose spin are entangled; they spin in opposite directions. He sends one to Alice. By Bob's clock, he measures the spin of his electron at t=0. By Alice's clock, she measures the spin of her electron at t=0. Tell me the rest of the story.The aether proposal explains why quantum entanglement can appear to transcend the speed of light while general relativity and nonlocal quantum mechanics still hold, and does not entail the controversial issues of observer and measurement dependence that I think are a metaphysical illusion of logic and woo chasing its tail. — Enrique
So all you have is that "Something explains why quantum entanglement can appear to transcend the speed of light, and I call that something aether" That's not an explanation. — Banno

It would be more accurate to simply say that they demonstrate Bell's Theorem to be true, and to interpret that to mean that there are no classical HVT's.True, Bell's experiments rule out classical locality, so nonlocality still appears to obtain. — Enrique
I cannot comment on that; I asked about this in the prior post, but didn't get a response. What is your aether idea exactly? How does it explain entanglement? I started a story about Alice and Bob and entangled electrons for you... can you use your aether to finish it?My aether idea ... — Enrique
I can't comment on your aether theory; you didn't explain how it worked. Bohmian mechanics as I understand is not local.My aether idea and Bohmian mechanics in a much more developed way suggest nonclassical locality to explain observations of nonlocality. Apparent nonlocality is basically a given that has to be accounted for with a nonclassical model, but I think some kind of unintuitive locality must be found to obtain beneath it all. — Enrique
Why do you surmise that entanglement holding implies something is going on beyond what relativity can model?It has been proven that entanglement still holds, so whatever goes on is beyond what relativity can model. — Enrique
How does the aether resolve this? What does your aether do to resolve it?I'm claiming relativity theory is its own reference frame, making the assumption that matter cannot interact faster than light speed, and the aether hypothesis is one way of subverting those assumptions. — Enrique
I can't comment on your aether theory; you didn't explain how it worked. Bohmian mechanics as I understand is not local...What does your aether do? — InPitzotl
Since the "wavefunction" describes waves, we can conclude that these waves require a medium (commonly known as the ether). — Metaphysician Undercover
Wiki, wave function: "A wave function in quantum physics is a mathematical description...". I am going to assume you were being facetious. — tim wood

In 1822, Joseph Fourier showed that some functions could be written as an infinite sum of harmonics.[10]
Introduction
See also: Fourier analysis
One motivation for the Fourier transform comes from the study of Fourier series. In the study of Fourier series, complicated but periodic functions are written as the sum of simple waves mathematically represented by sines and cosines. The Fourier transform is an extension of the Fourier series that results when the period of the represented function is lengthened and allowed to approach infinity. — Wikipedia: Fourier Transform
Your explanation in my mind is defaulting on the promises. The huge distance versus the time scale involved is simply an example of non-locality. You promised to explain non-local effects predicted by QM, and even explicitly paid heed to delayed choice as an example of non-local effects happening. If your aether blows itself apart for experiments with second scales over distances of a light year, how can it explain experiments on the nanosecond scale with distances of 10 feet?The Alice and Bob situation would probably be impossible — Enrique
