Black Hole sucks all that gets closer to it. What about White Hole?

Does it repel matter and light?

    In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole, which can only be entered from the outside and from which matter and light cannot escape.

    There is no evidence that white holes exist, and black don't "suck", they have gravity.

      No. It is part of the solution of general relativity for certain kinds of black holes.

    General relativity is a time symmetric theory - looks the same regardless if time is going forward or backward. White holes appear in some solutions as time reversed black holes. So, imagine filming things falling into a black hole, then run the film backwards. That is what a white hole looks like.

      Note that I am not saying they exist, but just explaining what general relativity says they are.

    It's thought that white holes don't exist in our universe.

    Black holes do not "suck". When you fall down, do you say that the Earth "sucked" you down? You fall because of gravity. Black holes have gravity.
