A black hole is defined as a part of spacetime where gravity is so strong, that spacetime curvature reaches extreme levels. Not even light can escape.
Now as spacetime is curved inside the black hole, is matter curved too inside the black hole?
Can anything straigt (3D) exist inside the black hole? I mean except the direction towards the singularity.
If a straight (3D) rod (not lying in the direction towards the singularity) enters the gravitational zone of the black hole, will it bend?
Gravity bends spacetime around the black hole as per GR, and even the photon's path gets bent (actually it is a straight line in 4D spacetime).
- Now will the rod bend next to the black hole because of spacetime curvature or will it stay straight, and which way will it bend?
