Cosmic flares shot from exploding black holes could provide long-sought proof of extra spatial dimensions, new calculations suggest. Theoretical physicist Stephen Hawking predicted that black holes evaporate through a quantum process known as "Hawking evaporation" and can explode in brief bursts of energy before vanishing completely. picked by AutumnLotus 2 years ago tags exploding black holes hidden dimensions cosmic flares |

Professor Hawking is renowned for his brilliant work in Quantum Gravity and constant study of Black Holes. One of his theories demonstrates that black holes emit radiation, later named as Hawking radiation. picked by pepersconc 2 years ago 4 comments edit related share science |
Like cosmic bubble makers, some black holes spew out behemoth blobs of hot gas into their home galaxies. 1 comments edit related share scienceThe bubbles ultimately pop, and their gassy contents keep both the black hole and its galaxy from ballooning to mega sizes, a new study finds. picked by AutumnLotus 1 year ago |
Super Massive Black Holes at the heart of galaxies may have been their progenitors and not the other way round as had been thought according to new research. picked by pocksucket 11 months ago 2 comments edit related share science |
New research shows that black holes are not the ultimate destroyers that are often portrayed in popular culture. Instead, warm gas escaping from the clutches of enormous black holes could be one source of the chemical elements that make life possible. picked by AutumnLotus 3 years ago 0 comments edit related share science |
Researchers finally have strong evidence for the existence of a binary black hole system, a long-theorized result of galactic mergers that features two black holes orbiting around each other at the center of large galaxy. 0 comments edit related share scienceThe black holes are expected to merge in what astronomers figure would be one of the most energetic events in the universe. picked by AutumnLotus 9 months ago |

The first black holes in the universe had dramatic effects on their surroundings despite the fact that they were small and grew very slowly, according to recent supercomputer simulations. picked by AutumnLotus 4 months ago 0 comments edit related share science |
The new method to create a tiny quantum sized black hole would allow researchers to better understand what physicist Stephen Hawking proposed more than 35 years ago: black holes are not totally void of activity; they emit photons, which is now known as Hawking radiation. picked by kakana 3 months ago 0 comments edit related share science |
The most energetic particles in the universe likely come from enormous black holes nestled in the restless hearts of traumatized galaxies, scientists say. Where these cosmic "bullets" originated has been a source of much speculation, with scientists proposing everything from gamma ray bursts to decaying dark matter. picked by AutumnLotus 2 years ago 1 comments edit related share plime.com |
IT IS the ultimate cosmic villain: space and time come to an abrupt end in its presence and the laws of physics break down. Now it seems a "naked" black hole may yet emerge in our universe, after spinning away its event horizon. picked by AutumnLotus 4 months ago 0 comments edit related share science |
Researchers from Duke University and the University of Cambridge think there is a way to determine whether some black holes are not actually black. Finding such an unmasked form of what physicists term a singularity "would shock the foundation of general relativity." picked by AutumnLotus 2 years ago 4 comments edit related share plime.com |
You wouldn't want to eat one, but you might take comfort in the new knowledge that a black hole and its surrounding material take the shape of a doughnut regardless of the mass of the black hole itself. picked by AutumnLotus 12 months ago 0 comments edit related share science |

Astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies, and gas, and the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new discovery dwarfs them all. picked by 2manyusernames 2 years ago 3 comments edit related share plime.com |
Spitzer Space Telescopes show that the vicinities around the black holes could be backing up with excess matter - the black holes just can’t consume it fast enough to clear the space. When this happens, the matter heats up, and releases a tremendous amount of energy. picked by 2manyusernames 3 years ago 0 comments edit related share plime.com |
