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

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 ...

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 ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

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 ...

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

"Nobody knew that before. It improves our knowledge of the theory itself, the theory of how clocks tick and relativity. The passage of time is fundamental to the theory of relativity: how you realize ...

Thanks to Albert Einstein, the US Government wants to establish an official time zone for the Moon. It has less to do with jet lag and more to do with how gravity affects time and can throw a lot of ...

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 ...
