      I had to google what a white hole was, and I’d prefer not to copy and paste from Wikipedia to answer your question. Perhaps one of the others has an answer?

      As far as I understand, this comes from Stephen Hawkin, who likes to think about time not as a constant thing, but going in all sorts of directions. So a white hole is a black hole, but with time going the other way. So rather than appearing to suck everything in like a black hole, it pushes everything out (including light).

      You have to have a really good imagination to think like he does! What a cool idea
