Why is an anomaly like a BH considered a singularity?
Why is a BH not considered to be a super massive object existing in our space-time...
It's a theoretical box. It could be any size you like. What was in the box prior doesn't change the idea that there's nothing but space-time in the box now.
The idea is that gravity can't exist unless matter and space-time interact.
OKay... back to my original question as to why gravity is a fundamental force.
I have another question. Let's say I have a box and I fill this box with space-time, the stuff that makes space, and nothing else. There would be no fundamental forces present in this box. Outside the box, I...
This is great. Thanks everyone for your input. I have another related question.
So does gravity have a minimum threshold? That is, does gravity affect atoms?

This is not a homework question. I'm 41 and have recently become interested in physics but have no background in the field. My question is this:
Does General Relativity account for tension in Space-Time?
That is, when space-time becomes extremely vast, where there is very little matter...
