Letters from the November 27, 2004, issue of Science News
Dark Secrets Astronomers and physicists seem to speak of black holes as though they took matter completely out of the universe (“Information, Please,” SN: 9/25/04, p. 202: Information, Please). An evaporating black hole would not fizz away into nothingness. It would lose energy and reappear in normal space as a very dense object (complete with […]
