These notes represent approximately one semester's worth of lectures on introductory general relativity for beginning graduate students in physics. Topics include manifolds, Riemannian geometry, Einstein's equations, and three applications: gravitational radiation, black holes, and cosmology.

> So you are saying, there is a semi-reversible process where energy and volume are correlated? My original objection was to you thinking of it as a "process", or at least a process involving energy and volume. It's a relationship between stress-energy and spacetime geometry. >…
> Black holes are ordinary objects, if they are anything at all. No, they aren't. Their spacetime geometries are very, very different from those of ordinary objects. > Take any normal object and give it the mass of a black hole There is no such thing as "the mass of a black…
> I'm very sure that you are wrong here What actual textbooks on relativity have you studied? If you haven't studied any, I would strongly suggest doing so before being this confident about your beliefs about relativity. Many pop science sources (including, unfortunately, books…
These are pretty good notes. Here is the PDF version: https://arxiv.org/abs/gr-qc/9712019
It's hard to gauge (pardon the pun) where to start you based on that. I'll guess that you're keen on understanding the General Relativity part in detail. Carroll and ‘t Hooft have kindly put up lecture notes that might be a good starting place. Stefan Waner has made available…

Oh please. Do you really think the people who won the nobel prize for this discovery have a grade school level understanding of speed? You seem to be talking about peculiar velocities, which are absolutely negligible on cosmological scales and only the velocity caused by the…
