Quote - Are you familiar with the Michelson-Morley experiment and the Lorentz transformations? That's where the speed limit of the Theory of Relativity comes.

Yep, that's what apparently some people don't know: Einstein came up with Special Relativity as a consequence of the speed limit. He didn't come up with that out of nowhere. His initial thought experiments were wondering what would happen when you started approaching the speed of light, and everything else falls from that.

Incidentally, that Einstein was right is proven every time you use anything that has a GPS.
