Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An image of a black hole surrounded by matter. Does the secret of quantum gravity lie around ...

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 ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

Some quantum systems may have two arrows of time, one running forwards as usual and another moving backwards. This means that, at some extremely small scales, time may have the option of moving in ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

Every year, Santa Claus races around the globe in a matter of hours to bring presents to children all over the world.

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." When you purchase through links on our site, we may earn an affiliate ...
