I also note that your definition of "scientific validity" is merely reducible to abstract numbers divorced from physical conditions that would otherwise render the theory physically impossible (e.g. A>B and A<B)
The claim is that if we construct an apparatus sufficiently accurate to take the measurements, our Teslas will objectively appear to be shorter in moving frames of reference, consistent with the Lorentz contraction. There's nothing abstract about these numbers, on the contrary they're concrete predictions about the measurements we can expect to obtain. And if there's anything impossible about the idea that different measurements could be obtained, based on one's frame of reference, I'm failing to grok it.
On to Fizeau...
So I am going to give you that link - and you can also read there their vicious and misleading replies, which also reveal that no one had ever noticed Einstein's imposture before.
Thanks for the link. I found that the poster known as KJW did a good job representing an Einsteinian perspective. I specifically agree with KJW, that Einstein is completely exonerated from accusations of fraud. Einstein accurately stated Fizeau's conclusion, and then explained why he believed his equation was identical, in sufficient detail that the missing terms are easy to supply.
Hence for high v with high w we predict experimentally, from Fizeau's equation, that light, piggy-backed by transparent media (whether fluid or solid) can indeed travel faster than c relative to its source.
Here I find that it is you, Mr. Badley, who is misinterpreting Fizeau's experimental finding. Because as KJW explained, Fizeau's experiment has not been accomplished with sufficient precision to distinguish between Fizeau's form of the equation, vs. Einstein's approximation. Therefore, your conclusions cannot be predicted based on Fizeau's experiment.
Maybe Einstein was right, that nothing can travel faster than light speed. Or maybe Dr. Spock is right, that warp drive is a "Logical" consequence of the properties of dilithium crystals.
Or maybe you're right, Mr. Claude Badley: maybe there's been some terrible mistake. Maybe "spooky action at a distance" does indeed permit faster-than light communications. Maybe length and time dilation are instrumental errors.
But you're not going to convince me, except with some experimental evidence. All the hand-waving in the universe is not going to get us to Alpha Centauri any faster.
Speaking merely for myself, I must confess, that regardless of whether Einstein was right or wrong, or cosmic wormholes and spacetime warps truly exist or not, I am guilty of gross procrastination, in not having prepared any immediate escape plan from "this miserable polluted Earth and its collapsing environment", unless ("God" forbid), I am prematurely "Raptured" (culled) by the "clothed with the Sun" Coronavirus, Indeed!
ROFL!! Fear not, Seeker, for God has given us all things that are necessary for our salvation. The truth shall set you free. Take your Vitamin D and zinc, and everything should be fine. Or at least, until it isn't.
