I was watching a Vsauce video and learned that any two objects, like two baseballs, are attracted to each other because of their mass, and the bigger the mass, the more gravity an object has. What does mass have to do with gravity, and what causes gravity? Why does something just attract other things around it?

I think Steve Mould has a few videos on visualising gravity. The current theory is that gravity is the distortion of spacetime around an object – the more massive the object, the greater the distortion. For example, if you place a bowling ball on a sheet of fabric, it’ll cause the fabric around it to stretch as it pushes downwards. Imagine that, but on three dimensions.
