Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

The result from CERN confirms expectations, but it's the first time gravity’s effect on the stuff has actually been tested. Reading time 3 minutes In the 95 years we’ve known about antimatter, ...

The infamous twin paradox sends the astronaut Alice on a blazing-fast space voyage. When she returns to reunite with her twin, Bob, she finds that he has aged much faster than she has. It’s a ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The Universe, as we know it, has a fundamental flaw staring us right in ...

Let's talk about tiptoeing right next to a black hole. Not that you could do that, because the nearest one we know of, near the center of our galaxy, is impossible to get to. Even if you could travel ...

Lots of people, including Einstein (see above), talk about gravity, the restraining force which makes people walk on floors instead of floating in midair. What worries Roger Babson, 74, economic ...

We first discovered the laws of gravity, and then those of quantum mechanics. But new work suggests nature might go about it the other way around: space-time, and hence gravity, could emerge from a ...
