'The Big Bang Was Not the Beginning'

Roger Penrose says he's spotted signs from a previous universe

(Newser) - Look carefully into outer space and you might spot the remnants of a previous universe. So argues Roger Penrose, a pioneer in the study of black holes and one of three recipients of this year's Nobel Prize for Physics. "The Big Bang was not the beginning," he... More »

Among Nobel Winners: Guy Who Proved Einstein Wrong

Physics honor will be split between 3 scientists for their work on black holes

(Newser) - Three physicists have won this year’s Nobel Prize in physics for black hole discoveries and will split the $1.1 million award. The Royal Swedish Academy of Sciences said Tuesday that Briton Roger Penrose will receive half of this year's prize "for the discovery that black hole... More »

This Black Hole Can't Exist. And There It Is

LB-1 is way more massive than other stellar black holes in our galaxy

(Newser) - A stellar black hole, 70 times the mass of our sun? Not likely, experts said—and yet, there it is. A group of Chinese-led scientists have spotted this "monster" black hole some 15,000 light-years away and dubbed it LB-1, the Washington Post reports. "Black holes of such... More »

Black Holes Contain a Mysterious Force

Some of them are helping the universe expand, study says

(Newser) - Black holes are dense singularities that suck up matter, right? Not always, according to two scientists who say some black holes are likely objects filled with a mysterious energy. In Astrophysical Journal , Kevin Croker and Joel Weiner argue that the expansion of the universe—which is accelerating, apparently due to... More »

We May Soon See Something 'No Human Has Ever Seen'

Scientists may reveal photo of Sagittarius A* black hole in Milky Way

Earth to $273M Satellite: What Happened to You?

Japan tries reconnecting with Hitomi

(Newser) - Japan has sort of lost something—a $273M satellite just launched to monitor X-rays coming from galaxy clusters and black holes, Discovery News reports. "We're taking the situation seriously," says Saku Tsuneta, a senior official at the Japan Aerospace Exploration Agency (JAXA). "We know approximately where... More »

Hawking: 'Black Holes Ain't as Black as Painted'

Physicist claims to have solved the information paradox

(Newser) - "If you feel you are in a black hole, don't give up. There's a way out." So says Stephen Hawking in claiming to have resolved the so-called information paradox—the seemingly irreconcilable problem of two well-accepted tenets involving black holes. Quantum mechanics dictates that the information... More »

Professor: I've Got Proof Black Holes Don't Exist

Math just doesn't add up, argues UNC physicist

(Newser) - Massive stars don't just fade away, they collapse into black holes, right? Even non-scientists have at least a vague notion of these mysterious forces of nature out there in deep space. Well, sorry to spoil everybody's fun, but a physics professor at the University of North Carolina says... More »

Coming Soon: First-Ever Picture of a Black Hole

It will take an array of 50 telescopes to spot its shadow

(Newser) - How do you photograph a black hole, which is normally invisible due to the fact that its gravity is so intense it pulls in even light ? You probably won't be surprised to hear that it's never been done before—and that to do it for the first... More »

Mathematician Hawking 'Very Ill'

(Newser) - Cambridge University says famed mathematician Stephen Hawking was rushed to the hospital today and is "very ill." The university said Hawking had been fighting a chest infection for several weeks. Hawking, 67, gained fame for his work on black holes, and has remained active despite being stricken with... More »
