Scientists win Nobel physics prize

STOCKHOLM >> Three scientists won the Nobel Prize in physics Tuesday for establishi­ng the all-too-weird reality of black holes — the straight- out- of- science-fiction cosmic monsters that suck up light and time and will eventually swallow us, too.

Roger Penrose of Britain, Reinhard Genzel of Germany and Andrea Ghez of the United States explained to the world these dead ends of the cosmos that are still not completely understood but are deeply connected, somehow, to the creation of galaxies.

Penrose, an 89-year-old at the University of Oxford, received half of the prize for proving with mathematic­s in 1964 that Einstein’s general theory of relativity predicted the formation of black holes, even though Einstein himself didn’t think they existed.

Genzel, who is at both the Max Planck Institute in Germany and the University of California, Berkeley, and Ghez, of the University of California, Los Angeles, received the other half of the prize for discoverin­g in the 1990s a supermassi­ve black hole at the center of our gal

axy

Black holes fascinate people because “the idea of some monster out there sucking everything up is a pretty weird thing,” Penrose said an interview with The Associated Press. He said our galaxy and the galaxies near us “will ultimately get swallowed by one utterly huge black hole. This is the fate ... but not for an awful long time, so it’s not something to worry too much about.”

Black holes are at the center of every galaxy, and smaller ones dot the universe. Just their existence is mind-bending. They are so massive that nothing, not even light, can escape their gravitatio­nal pull. They warp and twist light in a way that seems unreal and cause time to slow and stop.

“Black holes, because they are so hard to understand, is what makes them so appealing,” Ghez, 55, said after be

coming the fourth woman ever to win a Nobel in physics. “I really think of science as a big, giant puzzle.”

While the three scientists showed the existence of black holes, it wasn’t until last year that people could see one for themselves when another science team captured the first and only optical image of one. It looks like a flaming doughnut from hell but is in a galaxy 53 million light-years from

Earth.

Penrose, a mathematic­al physicist who got the call from the Nobel Committee while in the shower, was surprised at his winning because his work is more theoretica­l than observatio­nal, and that’s not usually what wins physics Nobels.

What fascinated Penrose more than the black hole was what was at the other end of it, something called the “singularit­y.” It’s something science still can’t figure out.

“Singularit­y, that’s a place where the densities and cur

vatures go to infinity. You expect the physics go crazy,” he said from his home. “If you fall into a black hole, then you pretty well inevitably get squashed into this singularit­y at the end. And that’s the end.”

Penrose said he was walking to work with a colleague 56 years ago, thinking about “what it would be like to be in this situation where all this material is collapsing around you.” He realized he had “some strange feeling of elation,” and that was when things started coming together in his mind.
