Ultraprecise atomic clock experiments ensure Einstein’s predictions about time

Utilizing a single of the world’s most precise atomic clocks, physicists have demonstrated that time operates a very small little bit slower if you modify your peak higher than the Earth’s floor by a minuscule .008 inch (.2 millimeters) — roughly two times the width of a piece of paper. The finding is yet one more affirmation of Albert Einstein’s principle of relativity, which predicts that significant objects, like our earth, warp the passage of time and cause it to slow down. 

“We are talking about measuring a transform in how a clock ticks at a level a very little more substantial than a human hair,” explained Tobias Bothwell, a graduate college student in physics at JILA, which is operate by the National Institute of Benchmarks and Technological know-how (NIST) and the University of Colorado.
