article_snippet.sent: But send information into a black hole, and information's lost forever – or at least that's what many physicists have been arguing for nearly half a decade.
article_snippet.sent: Now, one scientist says this may not be true, and that interactions between particles emitted by a black hole can reveal information about what lies within.
article_snippet.sent: For nearly 40 years, physicists have argued that black holes suck in information and then evaporate without leaving behind any clues as to what physicists once contained. 
article_snippet.sent: According to our work, information isn't lost once information enters a black hole,' says Dejan Stojkovic, an associate professor of physics at the University at Buffalo.
article_snippet.sent: This is an important discovery because even physicists who believed information remains in black holes have struggled to show, mathematically, how this happens.
article_snippet.sent: The paradox posed a huge challenge for the field of physics because The paradox meant that information inside a black hole could be permanently lost when the black hole disappeared.
article_snippet.sent: How exactly it's possible to recover information from a black hole has remained a topic of debate.
article_snippet.sent: Instead of looking only at the particles a black hole emits, the latest study also takes into account the subtle interactions between the particles.
