Are you kidding? You can't even say Black Hole without a Marxist getting their panties in a wad.
I watched a sci-fi movie, was about a white-hole fragment hitting the Earth. I didn't know white holes existed, you don't hear much about them. Everyone has heard of black holes; they suck everything in around them and nothing much comes out of them. Speculation (2012) is that white holes create stuff, that the Big Bang itself was a white hole.
