Three mathematicians have a different explanation for the accelerating expansion of the universe that does without theories of 'dark energy.' Einstein's original equations for General Relativity ...

People call them hoverboards, but they clearly don't hover. If you haven't seen one, it's basically a Segway without the handle. So sure, riding one makes it look like you're gliding over the surface, ...

Even in some of the most extreme areas in the universe, Albert Einstein’s theory of general relativity seems to hold up. A test of a key tenet of general relativity using three stars has shown that ...

There's a scene in the middle of the second episode of SyFy's new series The Expanse where two characters are on the outside of a spaceship making repairs, and one loses his grip on a wrench. Which ...

General relativity describes gravitation in a geometrical framework generalizing special relativity and classical mechanics. This term includes theoretical studies of gravity, experimental studies of ...

Researchers used the Dark Energy Spectroscopic Instrument to map how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their observations line up with what Einstein's theory ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

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 ...

In a new study published in Physical Review D, Professor Ginestra Bianconi, Professor of Applied Mathematics at Queen Mary University of London, proposes a new framework that could revolutionize our ...

Though there is an overwhelming amount of information floating around out there about the theory of relativity in all her guises, I was stumped last week when my eight year old nephew asked me to ...
