Let me give you an analogy: A movie maker hands you an old 2D movie (on film). Instead of watching the movie using a projector and a screen, you cut the film into the individual frames and then you stack them one next to the other and you claim that you have discovered the 3D reality of the movie and anyone who actually watches the movie is stuck in a 2D world.

The difference is that I give you an explanation where the 2D drawings come from. You do not tell me where de 2D frames come from.

But your 4D block universe explanation of "reality" with regard to relativity is just a philosophical opinion. This has been explained to you and bobc2 so many times, I'm surprised you're still promoting it.

Vandam, the 4D space contains no information that's lost in a 2D section here. All of the physics of SR can be described in arbitrary N+1 space. You get identical time-dilation and space-contraction effects with absolutely identical formulae and absolutely identical explanations for any natural N. This is a 2D problem. One time and one coordinate.

Vandam, as you admitted in 37 both ghwellsjr's text and drawings are correct. The fact that they don't conform to your preferences is a matter of little consequence.

Thread is starting to veer away from physics. It is now done.
