|Dark matter more elusive than ever as scientists admit detector has failed to find mystery particle |

Dark matter is said to make up four fifths of the mass of the universe, but finding it is another matter entirely.
A team of scientists, including University College London, have turned off their £7 million ultra-sensitive detector after failing to pick up any hint of the most elusive material in the cosmos.
Despite probing ‘unexplored regions of parameter space’ researchers were left scratching their heads by the stubborn reluctance of dark matter to step in to the light.
“Though a positive signal would have been welcome, nature was not so kind,” Dr Cham Ghag, of UCL.
Scientists think large quantities of dark matter must exist because of the way its gravity affects the rotation of galaxies and bends light.
But although it appears to play a key role in binding together and shaping the cosmos, dark matter cannot be seen with conventional telescopes or instruments.
To find it, scientist built The Large Underground Xenon (Lux) experiment beneath a mile of rock in a former gold mine in South Dakota.
