Schwarzschild's solution, escape velocity, tidal forces, event horizon, geodesic, line element
Escape velocity for black holes depends on the region we are at.
When we are on the Schwarzschild’s sphere, it’s equal to the
velocity of light and when we are inside the Schwarzschild’s
sphere, it exceeds the velocity of light. On the other hand, tidal
forces act on the object and turn it apart into pieces. Based on
angular momentum conservation, as the pieces of object go
inside the Schwarzschild’s radius, because their distance with
singularity decreases, their velocity increases in order to make a
balance and the angular momentum stay constant.
The Schwarzschild’s solution for schwarzschild’s sphere and
inside, will show what happens to the space-time; in the
Schwarzschild’s sphere, the space would be undefined and the
time warps, but inside the sphere, "
