How Einstein became a star: Last year, you'll remember there was a lot of talk about particles (neutrinos) that seemed to be traveling faster than light, something most scientists believe is impossible. When people talk about Einstein's "theory" of relativity, they often make the mistake of thinking it's an untested idea - a lot of numbers scribbled on a blackboard. In fact, Einstein's theories have been tested and proved correct in many ways. One of Einstein's predictions is that light from stars gets bent by the Sun's gravity. That's an absolutely amazing idea: the Sun can *bend* light! But, during a solar eclipse of 29 May 1919, British scientist Sir Arthur Eddington observed stars near the Sun, noticed some of them were in the "wrong" place, and found Einstein was right. When the news broke, the press flocked to Einstein's door - and the man whose theory "moved the stars" became a star himself!
