Spacetime shrinks in a gravitational field. As I understand it, objects falling into a black hole will appear to contract in size and run slower as they approach the horizon. This is similar to how things contract and slow down when traveling close to the speed of light because they are traveling through more space points than the same process at zero speed. So perhaps in some sense space is accumulating near a black hole so that processes occur in a shorter distance when compared to distant observers. So if there is something causing space to bunch up and accumulate in gravitational fields, will this produce the curvature we see in general relativity?
