Talk:White Hole Creation/@comment-25502720-20150618085254/@comment-3568954-20170925094803

no shadow thats not even remotely true, the theory of a white hole makes no mention of releasing of photons, atoms etc etc. 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.

meaning the white hole doesn't spit matter and light out of it, the matter and light simply can escape its event horizon simply because it doesn't have the same properties of a black hole.

the only strong feature of a white hole in theory is that nothing can pentetrate its event horizon making it essentially a"indestructable barrier"
