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

Answer 1

We don’t exactly know where it comes from.

We know it works at large scales by warping space and time.

We can predict how it works at large scales using Einstein’s equations, but that doesn’t mean that these equations explain how gravity works on its most fundamental level, what causes it or how it is related to fields, elementary particles and so on.
