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. 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. Black holes are the remains of stars that have collapsed under their own gravity. Brandon Carter and Stephen Hawking proved the No-Hair Theorem mathematically in the early 1970s, showing that the size and shape of a rotating black hole. If you introduce a “soft” photon - or a photon that has no energy - into that vacuum, it changes the angular momentum. If you feel you are in a black hole, dont give up, says Professor Hawking. 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. In 1974 Hawking discovered that black holes are not completely black but instead emit what is now called Hawking radiation. However, Hawking posited something different - that black holes “leak” radiation over time, eventually fading away. He stole one part from Leonard Susskind and the rest is regurgitated from his past work.

In other words, black holes were considered featureless blobs of physics, with no way to tell just how they were formed. Answer (1 of 5): If you're talking about his 'new' solution to the black hole information paradox, it's a sham. 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 something can, or at least it can linger at the edges. Stephen Hawking, the British physicist who is well known for the discovery of Hawking Radiation, recently published a new paper that turned our conventional. The black hole area theorem, which Hawking derived in 1971 from Einstein’s theory of general relativity, states that it is impossible for the surface area of a black hole to decrease over time. The black hole is famously so dense, not even light can escape it. One of Stephen Hawking’s most famous theorems has been proven right, using ripples in space-time caused by the merging of two distant black holes.
