Light Beam
Light is reflected off a flexible shiny surface fixed to the end of a plastic tube. When one speaks into the tubes sound vibrations pass down the tube and make the surface vibrate. The reflected light is therefore sent off from the surface in a con....

If equal amounts of matter and anitmatter were created at the birth of the universe then why does our universe seem to be made almost entirely from matter? Dr Tara Shears tells us how this mystery could be explained by the Large Hadron Collider exper....
