On average, Martian time ticks roughly 477 millionths of a second faster than terrestrial clocks per Earth day. But the Red ...

The passage of time is fundamental to the theory of relativity: how you realize it, how you calculate it, and what influences it,” said Bijunath Patla, a physicist at the National Institute of ...

Even worse, the orbit of Mars is elliptical (think of a slight oval rather than a perfect circle), which means that sometimes ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

A new recipe for gravity could help solve some of the universe's greatest mysteries. It suggests that the concept of "quantum gravity" could arise from entropy, possibly solving puzzles put forth by ...

The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein's theory of general relativity. The new finding has suggested his theory is now 500 times harder to ...

A preliminary analysis of data from the Gravity Probe B satellite has confirmed that the Earth's mass distorts the fabric of space and time as predicted by Einstein's theory of general relativity.

Aristos is a Newsweek science and health reporter with the London, U.K., bureau. He is particularly focused on archaeology and paleontology, although he has covered a wide variety of topics ranging ...

Most lovers of science fiction are quick to tell you that there's a "time-honored" (pun intended) way to build a time machine - somehow get a wormhole and use it as a bridge to travel through time.

An artist's visualization of the star S0-2 as it passes by the supermassive black hole at the galactic center. As the star gets closer to the supermassive black hole, it experiences a gravitational ...
