He stole one part from Leonard Susskind and the rest is regurgitated from his past work. It was previously believed that things only get sucked into a black hole, but physicist Stephen Hawking famously showed that black holes emit an energy called. In the 1970s, John Wheelerwho popularised the term black holeand Jacob Bekenstein claimed that black holes have no hair, in the sense that the only properties a black hole could have were its mass, its electric charge and its.

In theory, if we got to and observed a black hole properly, we could determine a lot about the history of the galaxy in that particular neighborhood. Answer (1 of 5): If you're talking about his 'new' solution to the black hole information paradox, it's a sham. Stephen Hawking explains black holes in 90 seconds. Stephen Hawking spoke in Sweden regarding black holes and provided a new look inside. Black holes are all over the universe, and if this theory holds true, it would mean we could read them like rings on a tree. This is a bigger deal than you might at first think. Strominger likens it to a hard drive that can store infinite data about the universe. This would mean black holes have “hair,” long strands of zero-energy photons and gravitons that could tell us the history of that black hole. In other words, there are ways to determine what formed a black hole and what might have gotten sucked into it. However, he contended that the radiation would be so scrambled that scientists could never work backwards to understand what fell into the black hole in the first place. If you introduce a “soft” photon - or a photon that has no energy - into that vacuum, it changes the angular momentum. In 1974, Stephen Hawking found that matter and energy can escape a black hole through what is now known as Hawking radiation. However, physicist Stephen Hawking has proposed a new theory about black holes that suggests they not be as all-powerful as we once thought, although you still would never want fly into one. But that would leave an identical vacuum every time they left, so if you wanted to know what created that hole, you were back to square one.Ī new theory, developed by Hawking, his colleague Malcolm Perry, and Harvard theoretical physicist Andrew Strominger, argues otherwise. However, Hawking posited something different - that black holes “leak” radiation over time, eventually fading away. In other words, black holes were considered featureless blobs of physics, with no way to tell just how they were formed. This is the centerpiece of Stephen Hawking’s new theory about black holes.įor a long time, the general theory about black holes explained that they have no particular features beyond mass, spin and angular momentum. But then, as Afshordi noted, Stephen Hawking used quantum mechanics to predict that. But something can, or at least it can linger at the edges. The American theoretical physicist John Wheeler summed it up by saying: Black holes have no hair. The black hole is famously so dense, not even light can escape it.
