Spacetime represented in coordinate geometry

[geminihunter]

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.

hi geminihunter! welcome to pf!

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

3 spatial dimensions, and time, can't!

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