How are space and time interrelated?

Answer 1

So you ask a simple question ehh?
Well, in simple Euclidean space. Coordinates are all straight and at right angles to one another. Time is a separate variable. Relativity teaches that mass warps space and this makes the measurement of velocity (displacement as a fuction of time) impossible without taking both time and space into account simultaneously. Thus the idea of Space-time was constructed.
One might ask, "Isn't the universe really Euclidean and the warpage of space (or spacetime) merely an illusion?" Our best yardsticks are beams of light, and they all say that space is warped. So no, it isn't an illusion.

Make note of where you are right now and then ask yourself where you are right now. You are nowhere near where you just were. You are sitting in front of your computer on a turning around on a spinning planet revolving around a sun that is revolving around the center of a galaxy that's heading out for a date with Andromeda and all the while speeding away on the thinning expansion of the known universe at the rate of something near light speed. Now try to go back and map any of that. The only way to do it is to use time as a coordinate. It works the same way in both directions--you need time as a location.

Answer 2

Space and time are interconnected through the concept of spacetime in Einstein's theory of relativity. In this theory, space and time are viewed as components of a unified four-dimensional continuum. Changes in one's perspective on time can affect one's perception of distances in space, and the curvature of spacetime is influenced by the distribution of matter and energy within it.
