Einstein was right again. Scientists at the National Institute of Standards and Technology in Boulder, Colorado have proven that the great shock-haired sage was on point when he suggested back in 1907 that time goes faster at greater altitude.

The phenomenon, called gravitational time dilation, tests true everywhere from 30,000 feet to just one.
