Can spacetime really be infinitely curved (e.g by a black hole)? And if it can, wouldn't infinite curvature have infinite energy?

Question

Does infinite curvature of spacetime really exist in physical world?

At which point do you think general relativity claims spacetime to be "infinitely curved" (note that the "point" at the center of a Schwarzschild black hole is called a "singularity" for a reason)? — ACuriousMind, Nov 29 '16 at 22:53

Can space time really be infinitely curved (e.g by a black hole)?

A black hole doesn't curve spacetime, a black hole is (a region of) highly curved spacetime with, according to General Relativity (GR), a curvature singularity enclosed by an event horizon.

However, GR is a classical theory and, as far as we know, the physical world is better modeled with quantum theory. A quantum theory of gravity is still a work in progress.
