Untangling the black hole mess

University of Maryland scientists provided information from an experiment about the use of quantum mechanics to obtain data inside a black hole which is contrary to modern physics that states that information will be lost forever after being consumed in a black hole.

Black holes are spaces in the region that has a very strong gravitational force that does not allow anything, even light, to escape from it.

Kevin Landsman and his team demonstrated how and when to measure information that was scrambled inside a simple model of a black hole. Their study was published in the journal Nature. They also reiterated that it could help in developing quantum computers.

"In quantum physics, information cannot possibly be lost," Kevin Landsman, a physics graduate student at the Joint Quantum Institute (JQI) at the University of Maryland in College Park, told Live Science. "Instead, information can be hidden, or scrambled" among subatomic, inextricably linked particles."

Stephen Hawking showed that black holes can shrink over their lifetimes. He proposed the Hawking radiation that states that a black hole will disappear when enough energy is taken when pair or particles fall into the black hole while the other particle is propelled outward.

However, quantum mechanics states that the properties of a particle can never be destroyed which is contrary to the belief that no information can be retrieved from a black hole. This is called by physicists as the black hole information paradox.

Landsman and his team showed that the pair will provide information regarding the other. The outward-flying particle can provide information on its infalling partner.

"One can recover the information dropped into the black hole by doing a massive quantum calculation on these outgoing [particles]," Norman Yao, a physicist at the University of California, Berkeley, and member of the team, said in a statement.
