Learning General Relativity: Finding Examples with Numbers

[TimeRip496]

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.

Another solution you might want to look at is the FRW solution, used in cosmology. (Actually this is a family of solutions, as the Wiki page linked to below will show you.)

These links will give you the basics of the Schwarzschild and FRW solutions and how they are derived:
