“That is an extraordinary claim and has to be proved.”
I haven’t made any claim. All I have done is ask questions.
“Light would have to be zipping along at more than 2 million times c.”
Do you know of any provable physical limitations on the speed of light?
___________________________________________________________
The claim is implicit in your questions.
General Relativity is the physical limitation on the speed of light.
The theory concerns the known physical universe as it exists right now.
It seems wrong to me to assume that it has always been exactly the same. And unprovable, since it can't be observed or reproduced.
Good night.
