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

This episode of the Physics World Weekly podcast features Alex May, whose research explores the intersection of quantum ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

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

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 ...

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 ...

Unifying quantum mechanics with general relativity is the ultimate dream — or nightmare — of physics. It would be a way to finally describe the force of gravity with the tools of quantum mechanics, ...

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 theoretical proposal published in the journal Reports on Progress in Physics is making some bold claims about our previous understanding of quantum physics. Mainly, that we were wrong. The proposed ...
