This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

A physics problem you need to solve! ⚖️🪢 In this video, we break down a classic physics scenario involving two masses attached to a spring, with gravity acting on them. Learn how to approach the ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

If you want to understand gravity, it makes sense to study black holes. Nowhere else can you find so much gravity so conveniently compacted into such a relatively small space. In a way, in fact, black ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

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 ...

A team of physicists just snared $3 million for testing the law of gravity like never before. Eric Adelberger, Jens Gundlach and Blayne Heckel won the 2021 Breakthrough Prize in Fundamental Physics ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...
