Over the last two weeks you have probably picked up on the considerable excitement in the news over the confirmation of the existence of gravity wave. So why all the fuss?

Gravity waves were first predicted by Albert Einstein’s general theory of relativity over a century ago. Einstein postulated that objects like planets and stars, warp space time through their gravitational force. The classic illustration of this is a stretched piece of rubber onto which heavy spheres (representing planets, etc) are placed. The objects deform the rubber sheet into a valley around them, much like gravity warps the space time field. And it this which holds a moon in locked in orbit around its planet, and a planet around its star, all whirling in a never ending celestial dance. However, as predicted by Einstein, time is also being effected.
