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. That’s right, time literally passes more quickly for a person on the 18th floor than it does for a denizen of the rez-de-chausée. The phenomenon, called gravitational time dilation, tests true everywhere from 30,000 feet to just one.
So time to get movin’ on up and splurge on the penthouse suite? Not quite. The effect, though real, is also miniscule—adding just 90 billionths of a second to a 79-year lifespan. It takes more than 90 billionths of a second to change your mind. // Patrick Barrett
