Interesting question. I would guess that, as the universe continues to expand, it cools down. So, the galaxies are not moving faster, we are just moving slower. Just a guess.
Here it is from Wikepedia: The black hole aspect of the Schwarzschild solution was very controversial, and Einstein did not believe that singularities could be real.
I find it fascinating that relativity suggested the existence of singularities, which Einstein considered to be prohibited by the laws of classical physics. He never excepted their existence. So, Einstein didn't exactly disagree with his theory, but something "resulting" from his theory.
You should definitely learn geometry! It trains your brain to think in new ways, and is a fascinating subject. Some theories of physics, like the "General Theory of Relativity," are impossible to understand without geometry. You won't regret it!
