Spacetime represented in coordinate geometry

  • #1
if the 3 spatial dimensions are represented on a 3 axis graph. would time be a straight line through the origin? if not could your direct me to some reading that i may find answers? i'm uncertain whether space-time can be represented using euclidean geometry.

welcome to pf!

hi geminihunter! welcome to pf! :smile:

2 spatial dimensions, and time, can be represented on a 3 axis graph …

3 spatial dimensions, and time, can't! :wink:

(all books with space-time diagrams show 2 or even only 1 spatial dimension)
