Black holes are one of the greatest mysteries in the universe, with scientists constantly trying to find out revealing information about these structures in outer space. Sometimes they are incorrectly described as the “vacuum cleaners” of our world, These bodies, whose gravitational pull is so intense that not even light can escape once it passes the event horizon, have long been considered regions of space-time, where all the general laws of physics break down.
Theoretical physicists have long been amazed by what happens to the information that builds up matter when it goes into a black hole. The general laws of quantum mechanics say that information cannot be destroyed even though that very information seems to get lost and completely disappear when a black hole eventually evaporates.
Black holes present what is known as an information paradox. Generally, the laws of quantum mechanics tell us that everything in our universe is encoded with information about its component particles’ quantum states. This information should never entirely disappear, not even if something gets sucked up in a black hole. The fact that this information seems to get irreversibly lost when a black hole evaporates, has made physicists wonder for nearly four decades.
Stephen Hawking tries to offer a revealing alternative to the mystery of black holes. “Black holes are not as black as they’re painted”, he added. “They are not the eternal prisons we once thought”, they can be analyzed carefully and relevant conclusions can be highlighted.
Hawking declared yesterday that he has come to a completely new understanding about the effects of stars which collapse under the weight of their own gravity.
Hawking now believes that the fundamental code which ties the universe together escapes as a form of radiation that it’s been irrevocably transformed. But if what escapes is something completely different, doesn’t it mean that the initial piece of information got lost?
“Things can get out of a black hole both on the outside and possibly come out in another universe”, Hawking added yesterday.
This is not at all a new idea, it’s far from being revolutionary or extremely revealing at any point but it is the physicist’s latest attempt to answer a physics quandary that has been thorn in the side of groundbreaking theories about black holes, presented about 40 years ago.
