The news that Star Wars fans were expecting for years – scientists have created a light-saber!

However, the weapon are going to be of very little use if you're attempting to deflect the dark facet of the Force.

This molecule behaves sort of a Jedi’s light-saber – ‘an elegant weapon for a additional civilized age’, as Obi-Wan Kenobi represented it – by moving the sunshine particles around in an exceedingly solid mass.

But try and go through flesh with it or listen out for the acquainted ‘whoosh’ sound and you may be defeated.

‘Most of the properties of sunshine we all know regarding originate from the very fact that photons area unit massless and don't act,’ aforesaid university physics prof Mikhail Lukin.

‘What we've got done is produce a special sort of medium within which photons act with one another therefore powerfully that they act like they need mass, and bind along to make molecules.

‘They’re pushing against and deflect one another.’ He added: ‘The physics of what’s happening within these molecules is comparable to what we have a tendency to see in the movies.’

It was created by chance once a team managed to urge photons to stay along and kind a molecule.
