A telescope can’t see it but scientists are speculating that it makes up the majority of matter in our Universe. Its presence was postulated by the discovery that stars at the edges of Galaxies moved faster than expected. They surmised that this was due to a hitherto unknown gravitational force which is visually undetectable.

This brings us to THE LHC (Large Hadron Collider), which is due to fire up after a technical hitch scuppered its inauguration after an upgrade lasting 2 years to dramatically increase its power. This will allow particles to be fired at each other and the 13 trillion electrovolts collisions may produce something interesting, such as a dark matter particle or indications of further dimensions and at a rough price tag of around £13.5 billion so far, Money well spent ?
