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 ...

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.

If you're going to Mars you'd best take along a jar of anti-aging cream because while you're there you're going to age faster ...

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 ...

For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

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.

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.

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

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 ...

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 ...
