Einstein is confirmed, atomic clocks measure the expansion of time

According to General Relativity, two atomic clocks at different altitudes beat at different rates.

Time passes faster as we move away from the center of the Earth, Einstein said.

A study by the US National Institute of Standards and Technology (NIST) and the University of Colorado showed that two atomic clocks at different altitudes of just one millimeter beat at different rates. What was lower hit slower. The experiment was funded by the country’s armed forces.

In 1915 the German physicist interpreted gravity as a result of the deformation of spacetime. When an electron changes energy level, it absorbs or emits light with a frequency. These clocks measure time using a laser tuned to this frequency.
