eli5 How does gravity work? Where does it come from?

In: 28

Answer 1

There are 4 fundamental forces in nature: weak nuclear force, strong nuclear force, electromagnetic force and gravity.

Physicist still don’t exactly know where gravity comes from. All we know, it’s that it’s the weakest of all four.

According to Einstein, gravity is a distortion space time around heavy objects which is why it attracts other bodies (think of it like a bowing ball on a trampoline and how it bends it)

But where exactly this force comes from, as far as I know, is still a mystery.
