How do scientists use Einstein's theory to show that space is curved?

Einstein's General Theory of Relativity predicts that space-time is curved in the vicinity of mass. Scientists have performed experiments to measure this curvature: one such experiment measured the bending of light from distant stars as it passed close to the Sun during a total solar eclipse.

Extra credit for the student: What is the difference between Einstein's General Theory of Relativity and his Special Theory of Relativity?
