Learning General Relativity: Finding Examples with Numbers

Click For Summary
SUMMARY

This discussion focuses on the need for numerical examples to better understand the Einstein Field Equations in general relativity. The Schwarzschild solution is highlighted as a fundamental example that provides insight into the application of these equations. Additionally, the Friedmann–Lemaître–Robertson–Walker (FRW) solution is mentioned as a significant cosmological model. Participants recommend resources, including Wikipedia articles, for further exploration of these solutions and their derivations.

PREREQUISITES
  • Understanding of the Einstein Field Equations
  • Familiarity with the Schwarzschild solution
  • Knowledge of the Friedmann–Lemaître–Robertson–Walker (FRW) metric

I am currently learning general relativity and I kind of understand what the symbols in einstein field equationd represent. But I need example like those that involves actual numerical values. I have been trying to search for it online but I cant. So does anyone mind showing me how you apply einstein field equation using really simple example? Or maybe you can recommend me to any source which contains example with actual numbers.

I don't think numerical values help (how does "0.23" help?), but the easiest non-trivial spacetime is the Schwarzschild solution, this could help to understand how GR leads to something more than mathematics.
