Answer:
In theory, a white hole looks similar to a black hole, but instead of sucking matter in, a white hole pushes matter away. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
Answer:
Black holes are one of the strangest things in the Universe. They don't seem to make any sense at all. It is an enormous amount of matter packed into a minimal area.
