 White hole and comparison of White hole and Black hole

      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. White holes appear in the theory of eternal black hole.

       It is a particular kind of singularity, it cant be directly observed. Its escape velocity is greater than the speed of light. White hole is the hypotential features of the universe. but the black holess were the first thing considered as a theoretical curiousity. Its easy to prove that the white holes exist. white hole is considered as the opposite of the black holes becausethe black holes dont let anything escape from their surface and the white hole are eruptions of matter and nothing can get inside the white hole. white holes are the possible solution to the law of general realitive.
  white hole is the time reversal of teh black hole, it is actually expected to have gravity so thazt they can attract objects. ncollntision course with a white hole would never reach its point.
