In 1919, 14 years after Einstein published his theory of special relativity, scientists found the first proof for his theory. Then, in 2011, scientists found that Earth’s rotation “drags” spacetime, further proof that Einstein had it right! Applying his penetrating intellect to data gathered by simple instruments, Einstein devised deep physical theories that changed our view of the world. Over the last century, scientists have found that gravity bends light, neutron stars make gravitational waves, and a new state of matter exists near absolute zero: all predicted by Einstein. Although Einstein had neither satellites nor modern equipment, his theories are still on the money. What was his secret?
