Scientists find that time on Mars runs 477 microseconds faster than on Earth, a discovery that could enhance deep-space communication and future exploration ...

Scientists observed a spinning black hole dragging space and time as it tore apart a star, confirming a key prediction of Einstein’s theory of relativity ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and ...

Scientists reveal why time moves faster on Mars than on Earth, and how this affects future space communication and navigation ...

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

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 ...

An artist's impression depicts the accretion disc surrounding a black hole, in which the inner region of the disc wobbles. In ...

Three thought experiments involving “demons” have haunted physics for centuries. What should we make of them today?

In 1919, British astronomers Arthur Eddington and Frank Dyson organised an expedition to Príncipe, a forested fleck of land ...

The exploration of quantum information challenges objective reality, positing the universe as a hologram is explored through ...

Clocks tick faster on Mars than they do on Earth, in part because Mars experiences less gravitational pull from the Sun. Now scientists have calculated just how much faster -- 477 microseconds, on ...

A Star Trek–inspired idea by Miguel Alcubierre kicked off decades of theory and experiments as scientists pursue plausible ...
