Yes I will try to. I look forward trying to understand it better. Thanks AndrewPeterDonis said:Probably the first thing to learn in this regard is to stop thinking in terms of "time and space" and start thinking in terms of "spacetime", a single 4-dimensional geometric object. Spacetime does have timelike curves and vectors and spacelike curves and vectors (it also has null curves and vectors, which have no counterpart at all in the ordinary conceptual scheme that the terms "time" and "space" are part of), but there is no one single aspect of spacetime that corresponds to "time" or "space".
