Physicists in England claim they have discovered how to create matter from light, by smashing together individual massless protons -- a feat that was first theorized back in 1934, and has been considered practically impossible until now. If this new discovery pans out, the final piece of the physics jigsaw puzzle that describes how light and matter interact would be complete. No one's quite sure of the repercussions if matter can indeed be produced from photon-photon collision, but I'm sure something awesomely scientific will emerge before long.
