User blog:Prstem/white and black holes

ok so just recently i learned about white holes and i had already known about back holes and i will describe what they are and if anyone sees this then please tell me if my hypothesis is correct ok so what is a black hole well a black hole is a thing in space that suck up spacetime until it is one infinitely dense point and nothing can escape it not even light and a white hole as also another thing in space but it spits spacetime out from a infinitely dense point into space well this is my question if something were to go into a black hole in one universe could it come out of a white hole in another universe and if so if a person were to survive going in to a black hole would it be able to use black and white holes to travel different universes and eventually end backup in there own universe
