But we've been here before. I told you earlier in this thread he's a crackpot. He defines four velocity completely wrong. He defines it as the derivative of the position coordinate with respect to the time coordinate. That's obviously useless, because the coordinate is just that: a coordinate. It's meaningless outside that coordinate system. He should use the proper time, usually denoted with a Greek symbol tau. That's an invariant, and meaningful. But he doesn't. Because he doesn't understand any of this. And that's why there's so much supporting evidence for relativity, contradicting this guy. No more puzzle.

He doesn't prove anything. He's a crackpot. He's not a scientist at all, and seems to struggle with mathematics. So why do you believe him?

I believe what he is saying makes sense, a lot more sense than the far out theories that are accepted. I do not believe in a block universe where time dilates or where there are wormholes that can take us back in time. Sorry. BTW, he was very clear that he was not rejecting or badmouthing special or general relativity. He was refuting the claims made on the basis of their correctness.

Not Against Relativity

I get angry emails from people accusing me of badmouthing relativity, one of the most corroborated theories of physics. I am not. In my opinion, the special and general theories of relativity are mathematically correct and make correct predictions. What is wrong are all the obviously false claims made on the basis of their correctness. Relativity does not allow motion in spacetime or time travel, as Dr. Wheeler, Sir Stephen Hawking, Dr. Kip Thorne and the others claim. It forbids motion in spacetime!
