LONDON: An international team of scientists has predicted that our galaxy, the Milky Way, contains a disk of 'dark matter'.

 

The team includes astronomers Dr Justin Read, Professor George Lake and Oscar Agertz of the University of Zurich, and Dr Victor Debattista of the University of Central Lancashire, who have used the results of a supercomputer simulation to deduce the presence of this disk.

 

They have explained how the simulation could allow physicists to directly detect and identify the nature of dark matter for the first time.

 

Unlike the familiar 'normal' matter that makes up stars, gas and dust, 'dark' matter is invisible but its presence can be inferred through its gravitational influence on its surroundings.

 

Physicists believe that it makes up 22 per cent of the mass of the Universe, compared with the 4 per cent of normal matter and 74 per cent comprising the mysterious 'dark energy'.
