A Briton is among three scientists who have won this year’s Nobel Prize in physics for advancing our understanding of black holes.

The Royal Swedish Academy of Sciences said Sir 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 centre 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.

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

Mr Genzel and Ms Ghez looked at the dust-covered centre of our Milky Way galaxy where something strange was going on – several stars moving around something they could not see.

It was a black hole – not just an ordinary black hole, but a supermassive black hole, four million times the mass of our sun.

Now scientists know that all galaxies have supermassive black holes.

The prestigious award comes with a gold medal and prize money of 10 million Swedish kronor (£864,000), courtesy of a bequest left 124 years ago by the prize’s creator, Swedish inventor Alfred Nobel. The amount was increased recently to adjust for inflation.

On Monday, the Nobel Committee awarded the prize for physiology and medicine to Americans Harvey J Alter and Charles M Rice and British-born scientist Michael Houghton for discovering the liver-ravaging hepatitis C virus.

The other prizes, to be announced in the coming days, are for outstanding work in the fields of chemistry, literature, peace and economics.
