Can we imagine black hole in this way??
For a hole on a sheet of paper we need 3 dimensions to fall through and come out from behind. Note that there is only an axial direction for entry.
So to fall in a black hole which should be hole in space itself, we would need 4 dimensions to pass through and the twist is that we can enter from all directions.

Well nice idea , just a point of fact i wanna say they do might be holes of 4d ( we live in 4d 4th dimension is time) , but this is only when you see them in time space fabric imagination, actually I think black holes might not be holes , they are dead remiss of hyper dense cores if star like if someone asks you to fill an Empty space with material very very tightly how can it be a hole ?
