Without a Proof, Mathematicians Wonder How Much Evidence Is Enough
...complicated or forbidding to study directly. By creating a black hole analogue in a laboratory, you might be able to learn something about how real black holes behave without having...
Physicists Debate Hawking’s Idea That the Universe Had No Beginning
...they met in Cambridge for long periods of collaboration. The duo’s theoretical investigations of black holes and the mysterious singularities at their centers had turned them on to the question...
Social Distancing From the Stars
