Spacetime represented in coordinate geometry

Click For Summary
SUMMARY

In the discussion regarding the representation of spacetime in coordinate geometry, it is established that while two spatial dimensions can be represented alongside time on a three-axis graph, three spatial dimensions cannot. This conclusion is supported by the observation that all literature on spacetime diagrams typically illustrates only one or two spatial dimensions. Participants emphasize the limitations of Euclidean geometry in accurately depicting the complexities of spacetime.

PREREQUISITES
  • Understanding of coordinate geometry
  • Familiarity with spacetime concepts
  • Knowledge of Euclidean geometry limitations
  • Basic grasp of dimensional analysis
NEXT STEPS
  • Research "spacetime diagrams in physics" for visual representations
  • Explore "non-Euclidean geometry" to understand alternative models
  • Study "theories of relativity" for insights on spacetime structure
  • Investigate "dimensional analysis" in advanced physics contexts
USEFUL FOR

Students of physics, mathematicians, and anyone interested in the geometric representation of spacetime concepts will benefit from this discussion.

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! :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)
