Information isn't gone forever once it enters a black hole

Although many scientists believe that information vanishes when it enters a black hole, researchers at the University of Buffalo have recently contradicted this idea by stating that the information isn’t erased at all.  “According to our work, information isn't lost once it enters a black hole," says Dejan Stojkovic, PhD, associate professor of physics at the University at Buffalo. "It doesn't just disappear."  In his new study, "Radiation from a Collapsing Object is Manifestly Unitary," Stojkovic discusses how particles produced by black holes interact with each other, showing us different features about the information that has entered the black hole.  Until this point, it was difficult to prove that information isn’t erased when it enters a black hole.  Now, Stojkovic has included calculations his the study to support the idea that the information is conserved.  In this study, the exchanges between the particles were examined and the scientists determined that you can potentially retrieve the information once it enters the black hole.
