Tom, I enjoyed your post, but if you are going to convince relativists that SR is false then you need to at least play by their rules. There is no reason to say the relative speed is just the exhaust velocity. When the rocket is being held down immediately before lift off, the exhaust velocity is the same but no one would say the rocket has gained relativistic mass. Once the rocket is in flight, an observer on the Earth, or anywhere else, is entitled to measure the relative speed and draw their conclusions, rightly or wrongly, about the rocket’s mass - whether or not its motor is on at the time.

We clearly share a disbelief of SR, but this is a thread about magnetism. We don’t yet agree about time dilation so I’ll start a new thread and see how far it gets. It might provoke more interest than my evidence against the fundamental beliefs of EM.

Very good points +1
