(Phys.org)—It was another good week for physics as a team of researchers with the University of Waterloo found that a photon “afterglow” could transmit information without transmitting energy—though the receiver must expend energy to read that information. Also good news for physicists trying to solve the “information loss paradox”—a team of researchers has found a way to show that black holes don’t erase information—they claim that interactions between particles emitted by a black hole can be used to reveal information about material that “disappeared” inside of it
