Einstein's general relativity says gravity is spacetime curvature, but what does that mean? Let's take a look at how gravitational time dilation results in a...
Matter bends spacetime. Spacetime tells matter how to move.
Using this logic, you can imagine that above a certain threshold, this can become a feedback loop. These locations are black holes, where enough matter located in a small enough volume of spacetime can create enough distortion to further force more matter into the same volume of spacetime.

How similar is this process to low/high air pressure systems?
