Universe evolution recreated in lab
By Pallab Ghosh Science correspondent, BBC News 7 May 2014
An international team of researchers has created the most complete visual simulation of how the Universe evolved.
The computer model shows how the first galaxies formed around clumps of a mysterious, invisible substance called dark matter.
It is the first time that the Universe has been modelled so extensively and to such great resolution.
The research has been published in the journal Nature.

Prof Richard Ellis Caltech The simulation will provide a test bed for emerging theories of what the Universe is made of and what makes it tick.
One of the world's leading authorities on galaxy formation, Professor Richard Ellis of the California Institute of Technology (Caltech) in Pasadena, described the simulation as "fabulous".
The computer model draws on the theories of Professor Carlos Frenk of Durham University, UK, who said he was "pleased" that a computer model should come up with such a good result assuming that it began with dark matter.
"You can make stars and galaxies that look like the real thing. But it is the dark matter that is calling the shots".
