Well, I never included ether in any way from the beginning. I just
noticed that something was amiss with regard to simultaneity. I
resolved this by having the lightning leave marks on the railroad
track, which seems impossible for the Lorentz equations to resolve.
Then, again without ether, I figured the problem using velocity of
light rather than speed of light. I did what Einstein said he was
doing. So if there is some proof that ether exists, go ahead and give
it. Other than that, I just correct the mistakes of scientists.
