What is the credibility of the existence of white holes?

or more specifically: a reversal of a black hole





Just heard about this and it sound really interesting. would like hear from people who are more knowledgeable about this and get redirected to good sites about this theory|||White holes as the inverse to black holes WAS floated as a theory when quasars were first discovered, 30 years ago. There seemed no other way to explain the energy output. But now our theories are better and we understand that there is this MONSTER of a huge black hole in the heart of a quasar, so it all makes sense, plus the fact we have other evidence (photographic, Doppler, less active galaxies closer by as they age, etc).|||What the? You mean a point in space that you can't get to because of reverse gravity that pushes away everything at the speed of light?





Novel concept to me.|||sunh a phenominon realy does not exist.|||Below is a link from Wikipedia.





Nothing's crazy in the areas of science and space, there's still a lot we don't understand.





http://en.wikipedia.org/wiki/White_hole|||While it is definitely withing General Relativity, I don't think we have actually "viewed" them in the sence we have black holes. Also, black holes and white holes are in no way connected, one thing going into a black hole does not come out of a white whole. They're two seperate entities.|||Well yes, they're real. They've even been proven and have pictures of them. Or, what I call a white hole. The quasar of the black hole spits out all the stuff it's taken in and throws it out as energy.|||If there are black holes there are also white holes


But opposites attract so there would be neither,they would annihilate each other.
