Are manufacturer AC cables good enough?

Everything you never wanted to know about the thorny subject of gravity is contained in this book, pub. 1973. Authors Misner, Thorne & Wheeler. Big guns. That was the golden age for gravity and black holes, following the success of the A-Bomb and H Bomb, you known, those guys had to find something to do.

Well if I could figure gravity out and unify it then I will accept my "Noble" prize when the pandemic is over if I am still alive. 

Here’s a quick explanation. Imagine spacetime is a big mattress and all the heavenly bodies are about the size of golf balls and oranges and sitting on the mattress. If you place a big heavy bowling ball on the mattress those heavenly bodies closest to the bowling ball will slide down a little bit toward the bowling due to the depression caused by the bowling ball. That’s what gravity is, the curvature of spacetime due to very heavy objects. It all stems from the General Theory of Relativity.

Also interesting that NASA just realized that our atmosphere extends beyond the moon......           think about that one guys.

No, that is just a theory of gravity.
