Does the Lorentz Ether Theory "Work"?
in [Relativity]

From: Tom Adams on 13 Apr 2010 10:07 I know that Einstein eliminated the need to postulate the existence of ether based on the principles of Machian empiricism. But, otherwise, does the Lorentz ether theory work? Does the theory of length contraction caused by motion relative to the ether produce a theory that is equivalent to SRT?

It works in the domain of SR, but not GR. There are aether theories that are being worked out for GR's domain, but they so far make observable predictions that are falsified (or at least appear to be). > Does the theory of length contraction > caused by motion relative to the ether > produce a theory that is equivalent to SRT? Yes. They are identical in terms of observables. David A. Smith

No. If there were any aether it would produce turbulence. > Does the theory > of length contraction caused by motion relative to the ether produce a > theory that is equivalent to SRT? No. Besides which, crank Einstein's theory is length STRETCHING, the very opposite of crank Lorentz's theory. Both are idiotic. When I went to school, dividing by something less than unity would increase the quotient. xi = x' / sqrt (1-v^2/c^2) <=> xi > x'= x-vt Got any more crank sci-fi theories to promote, or can we get back to real physics?

The "equivalence" of LET and SR is rather restricted: within their mutual domain, Lorentz ether theory is experimentally indistinguishable from SR. But LET has a smaller domain of applicability: LET is restricted to geometry and electromagnetism, while SR is more generally applicable to any physical situation in which gravitation can be neglected. In order to expand LET's domain to that of SR, it is necessary to postulate a set of additional ethers that "just happen" to behave exactly the same as the lumeniferous ether. That makes it very ugly to modern eyes. Tom Roberts

What LET needs to change is the notion that aether is an absolutely stationary space. Aether and matter are different states of the same material. Aether is displaced by matter. Displacement creates pressure. Gravity is pressure exerted by aether displaced by matter. With this understanding of aether, LET is at least, if not more, applicable than SR because not everything is relative. Everything is with respect to the aether. For more information, see the 'Aether Displacement' thread (http:// groups.google.com/group/sci.physics.relativity/browse_frm/thread/ ff54796d46551426#) which starts off with: Aether and matter are different states of the same material. Aether is displaced by matter. Displacement creates pressure. Gravity is pressure exerted by aether displaced by matter. 'Frictionless supersolid a step closer' http://www.physorg.com/news185201084.html "Superfluidity and superconductivity cause particles to move without friction. Koos Gubbels investigated under what conditions such particles keep moving endlessly without losing energy, like a swimmer who takes one mighty stroke and then keeps gliding forever along the swimming pool." In the analogy the swimmer is any body and the water is the aether. Just as the swimmer displaces the water, whether the swimmer is at rest with respect to the water, or not, a body displaces the aether, whether the body is at rest with respect to the aether, or not. In the analogy the moving swimmer creates a displacement wave in the water. A moving body creates a displacement wave in the aether. 'On the super-fluid property of the relativistic physical vacuum medium and the inertial motion of particles' http://arxiv.org/ftp/gr-qc/papers/0701/0701155.pdf "Abstract: The similarity between the energy spectra of relativistic particles and that of quasi-particles in super-conductivity BCS theory makes us conjecture that the relativistic physical vacuum medium as the ground state of the background field is a super fluid medium, and the rest mass of a relativistic particle is like the energy gap of a quasi-particle. This conjecture is strongly supported by the results of our following investigation: a particle moving through the vacuum medium at a speed less than the speed of light in vacuum, though interacting with the vacuum medium, never feels friction force and thus undergoes a frictionless and inertial motion." A particle in the super fluid medium displaces the super fluid medium, whether the particle is at rest with respect to the super fluid medium, or not. A moving particle creates a displacement wave in the super fluid medium. A particle in the aether displaces the aether, whether the particle is at rest with respect to the aether, or not. The particle could be an individual nucleus. A moving particle creates a displacement wave in the aether. Aether is displaced by an individual nucleus. When discussing gravity as the pressure associated with the aether displaced by matter, what is being discussed is the aether being displaced by each and every nucleus which is the matter which is the object. |
