what is white hole?
A hypothetical hole in outer space from which energy, stars, and other celestial matter emerge or explode is called a white hole. This hypothetical cosmic body acts in the exact opposite manner of a black hole. Instead of pulling in matter, a white hole expels it like a sort of cosmic exhaust valve, giving off serious amounts of energy. Some cosmologists theorize that a black hole in one universe might empty out through a white hole in another universe.
