Thanks to Einstein's theory of relativity, numerous tests have concluded tangible effects on how we on Earth record and measure the passing of time.

Ten events that would unfold if gravity suddenly vanished, beginning with the effects on our bodies and ending with the ...

The third Quantum Gravity conference took place at Penn State University from 21 to 25 July 2025, bringing together ...

Traditional sensors or clocks would never be able to probe time differences at the quantum level. But when quantum superpositions and entanglement are used, entirely new effects can be measured.

Gravity affects how time moves, so NASA is tasked with establishing a lunar time scale to make missions safer in crowded outer space ...

The effect of gravity is a result of mass, as explained by researchers demonstrating gravity’s existence due to mass for the first time.

"My breakthrough was to realize that if gravity can affect time and light can create gravity, then light can affect time…And I realized that there was a special type of light that could do this ...

If it’s noon in New York, what time is it on the moon? And then there is the not so tiny problem of Einstein’s theory of relativity, which states that gravity affects time.
