Comment Points and curves (Score 1) 152
I know that anything that is called a straight line actually isn't a straight line, it is nonsense. A series of points that appear to be straight from our point of view.
There are points and curves. Curves are points that are spread over time with the curvature correlating with time. The shorter the time period, the tighter the curve. That is how Space is defined. If you examine it from a different perspective, the curvature of space describes time. (which is why gravity is always an 'attractive' force)
I still have no idea why spacetime exists. Just that it does.
