The Block Universe of Special Relativity

Jun 09, 2015
Commentary by Stephen Downes

My old friend Mike Rochfort sent me this link after a discussion online about events today determining what happened yesterday. No, this is not revisionist history, it's an artifact of space-time. So what is space-time realism? "The basic idea of using the special theory of relativity to prove determinism is that time can be treated mathematically as a fourth dimension. This gives us excellent results for experiments on moving objects and explains the strange Lorentz contraction of objects in space and dilations of clock speeds for observers in fast moving frames of reference (coordinate systems)." I'm not a space-time realist - but that's only because I think none of it is real!
