If you live on the top floor of a skyscraper, you may age faster than those living in the ground floor, American scientists have claimed citing Einstein’s theory of relativity.
Researchers at the National Institute of Standards and Technology , Colorado, have demonstrated that one of Albert Einstein’s theories of relativity that the further away from the Earth you are, the faster time passes works even on a human scale.
That means — even though the differences are tiny — people will really age faster if they live on the top floor of a skyscraper than in a bungalow, the Telegraph reported.
The discovery confirms a theory first proposed by Einstein that clocks run faster the further away from the ground they are — a phenomenon that works in space rockets and aircraft as the forward movement offsets the height. Using a pair of the world’s most precise clocks, physicists at the NIST, discovered that simply going upstairs will make you age faster.
If one of the clocks was moved just a foot higher, then it ran a little bit faster — albeit by a tiny fraction of a second, they found. So, taking just a couple of steps upwards will remove 90 billionths of a second to a 79-year lifetime, they said.
By moving about 10 feet to the top of the stairs, one would age quicker by 900 billionths of a second. And if you were to spend your life at the top of the 102-storey Empire State Building (1250 feet) you would lose 104 millionths of a second, said James Chin-Wen Chou, co-author of the study.
The researchers used “quantum logic” atomic clocks which can keep time to within one second over 3.7 billion years.
They proved the theory that clocks at higher elevations run faster because they are subject to less gravitational force.
A NIST spokesman, however , said the phenomenon, called “gravitational time dilation” , would not impact people’s lives.
“The difference is much too small for humans to perceive but it may provide practical applications in geophysics and other fields,” he said.
According to Einstein’s theory of relativity, big objects with lots of gravity — planets or stars — bend the fabric of time and space, like bowling balls on a trampoline. The closer you get to these objects, the stronger the pull of gravity and the slower time moves. An astronaut watching a clock fall into a black hole, for example, would see its hands gradually slow down as gravity increases.
