I don’t see why you would expect that last to be true in general. Starting from T with indexes down, in one case you have the metric...

Not sure why you think that. The wave function shows the interference -- it interferes with itself, as mentioned above.

In the case where you're running the experiment one quantum at a time (because the source is at sufficiently low intensity), each...

What do you mean by "quantum forces"?

No. If you're using QM--and really the path integral version of QM--in this way, you're not talking about EM waves any more. You're...

If by "special relativity" you mean "my own personal intuition about length contraction", yes, but looking at the whole circumference...

After some thinking, I believe it's only a problem in notation. To make the explanation simpler, I find convenient to use an index-free...

I'm not sure your scenario can even be analyzed, since it appears to contain internal contradictions. I've pointed a few of them out in...

I don't understand what this means either.

It's impossible for any ship to have a path through spacetime that's shorter than the path of a light ray. The length of a light ray's...

It's impossible for any ship to move along with the CMB. The CMB moves at the speed of light. And CMB radiation is moving at the speed...

I don't understand what you mean by this. What does the length in spacetime of the ship's path have to do with the apparent speed of the...

But the change in topology does create something that is not present in SR on ##R^4##: a preferred frame. To see how this works...

In such a universe the first postulate does not hold. So you have to be careful with any "these frames contradict" type of reasoning...

I wouldn’t say it was even a new interpretation so much as a new derivation. His main contribution was taking Lorentz aether theory...
