Social feeds are filling with breathless claims that on 8/12/26, Earth will briefly “turn off” gravity for seven seconds, ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

Flashes like Cherenkov radiation in space may reveal negative-energy ghosts, hinting at gaps in gravity theories.

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

What is NASA Project Anchor and can gravity blackout happen ever? A viral claim says Earth will lose gravity for seven ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

C hina has decided to take hypergravity to a whole new level – testing both materials and fundamental physics in a regime we ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Isaac Newton confessed that he had no idea what gravity was. The 17th century English polymath knew what it did, and he described it with a universal law of gravitation. But where the law came from, ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...
