SUMMARY

The discussion focuses on the relationship between mass constraints and space-time diagrams in the context of the De Sitter light cone. It establishes that mass (M) influences the nature of time-like, null, and space-like intervals, defined by the equations M^2 = 1 for null, M^2 > 0 for time-like, and M^2 < 0 for space-like. The participant initially struggles with visualizing these concepts through plotting the function t(x) but later resolves their confusion. This indicates that a deeper understanding of the underlying physics is necessary for accurate representation.

PREREQUISITES
  • Understanding of mass-energy equivalence in physics

Hey there!

I'm relatively new to this website and I have a quick question. If I have some function t(x), that is time for a given x, with a M (mass) constraint, namely...

M^2 = 1 --> Null

M^2 > 0 --> Time-like

M^2 < 0 --> Space-like

If I wanted to see what these space-time diagrams looked like for different curves, is it more complicated than simply just plotting this t(x) function with different masses? When I do this my answer is making close to no sense.
