Theory of Relativity

Einstein's theory of Relativity dictates that the closer you are to the center of the earth, the lower time goes.

For example, at the top of Mount Everest, a year would be about 15 microseconds shorter than at sea level.

Scientists have tested Einstein's theory of Relativity at the small distances we travel up and down every day.

Using the World's most precise clocks, they confirmed that our wristwatches tick at a slightly different speed when we ride an elevator climb a flight of stairs, or even sit upright in bed.
