Three scientists won this year’s Nobel Prize in physics for advancing our understanding of black holes, ABC News reported today.

The Royal Swedish Academy of Sciences said that Briton Roger Penrose will receive half of this year’s prize “for the discovery that black hole formation is a robust prediction of the general theory of relativity.”

Goran K. Hansson, the academy’s secretary-general, said German Reinhard Genzel and American Andrea Ghez will receive the second half of the prize “for the discovery of a supermassive compact object at the center of our galaxy.”

The prizes celebrate “one of the most exotic objects in the universe,” black holes, which have become a staple of science fiction and science fact and where time even seems to stand still, Nobel committee scientists said.

Penrose proved with mathematics that the formation of black holes was possible, based heavily on Albert Einstein’s general theory of relativity.

Genzel and Ghez looked at the dust-covered center of the Milky Way galaxy where something strange was going on, several stars moving around something they couldn’t see.

It was a black hole. Not just an ordinary black hole, but a supermassive black hole, 4 million times the mass of our sun.

Now scientists know that all galaxies have supermassive black holes.
