eli5 How does gravity work? Where does it come from?
In: 28
as far as we understand now, it’s just a fundamental property of the universe. It doesn’t come from anywhere else, it just is. If you can find out what causes gravity to exist, cone collect your nobel prize.
More specifically, what’s fundamental is that mass warps spacetime. Gravity isn’t a *force* so much as the natural consequence of objects moving in curved space. No one has any answer why mass curves spacetime beyond “it juat does”.
