The three scientists won the Nobel Prize
in physics this year for establishing the reality of black holes — the possible
cosmic monsters that often suck up light and time.
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 super-massive black hole at the center of our
galaxy.
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 becoming the fourth woman ever to win a
Nobel in physics. While the three scientists showed the existence of black
holes, it was not 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
Nobles. What fascinated Penrose more than the black hole was what something was
at another end of it called the “singularity”. 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.
