We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

Time runs faster on Mars (477 microseconds/day) due to relativity. Discover how this fundamental physics challenge requires dynamic correction to prevent massive GPS errors and secure future deep ...

In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

A new software package detailed by Chinese scientists promises to tell what time it is on the moon, accounting for effects of relativity.

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”. However, Lorentz invariance – the theory that the same rules of physics ...
