doesn't 4th just include time with a 3d object.
Would things like waves/pulses fall under that?
5th seems to be used in the Kaluza-Klein theory[0] for gravitation and electromagnetism. [0] https://en.m.wikipedia.org/wiki/Kaluza%E2%80%93Klein_theory edit: I agree, I don't know why you got down voted. It was a thought provoking question. |
