I only have time to read the first link, yet being attracted and will read others later on.

At the bottom of that web page, author Louis Savain shows his most honorable endeavour by allowing Copy and distribute freely his insightful writings.

I agree with his derivation that in spacetime methodology, nothing can move along the time axis because v=dt/dt=1 . whereas spacetime diagram usually take c as the unit. (so, actually v=c.dt/dt=c) [whereas time axis employs a constant ci (c is speed of light, i is sq.rt. of negative 1) to make time axis be convertible to spatial axes.]

For spacetime physicists, things cannot move in spacetime still do no harms. It seems that they really take all things become a "block universe" or a jelly, being fixed relative to each other. The whole universe only reproduces itself or progresses itself like a big jelly or many slices of sandwiches. That is why they accept that those past happenings never disappear. All historical things are still waiting for a time-traveller to go back there and eat the jelly or sandwich.

Crackpot.
