The idea contradicts the conventional view of black holes, which says that all the matter inside is crammed into an infinitely dense point. And by providing a way for black holes to send out information about their contents, it could resolve a profound paradox in physics.
Samir Mathur and his colleagues at Ohio State University in Columbus were investigating a puzzle called the black-hole information paradox. The gist is that the theory of quantum mechanics says information must be preserved – it cannot be created or…
