Theoretical physicists have spent decades wrestling with a disorienting possibility: that the flow of time is not woven into the basic laws of physics but instead emerges from gravity’s effect on heat ...

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 ...

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 ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Scientists have proposed a new test to hopefully help shed some light on quantum ...

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 ...

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity ...

A bundle of magnets and glass had a slight but detectable gravitational pull, pushing scientists closer to the boundary between classical and quantum physics. Reading time 3 minutes Despite keeping us ...

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 ...
