Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.

But what is it, how does it work?

Answer 1

It’s a property of the geometry of spacetime, prompted by the presence of matter. It causes the worldlines of objects (that is, their paths through spacetime) to curve.

In other words, matter tells spacetime how to curve. That is gravity.
