For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

(via Sabine Hossenfelder) Over the past few decades, the idea that gravity is not a fundamental interaction but is instead caused by the increase of entropy has become increasingly popular in the ...

Add Yahoo as a preferred source to see more of our stories on Google. A new way of explaining gravity could bring us a step closer to resolving the heretofore irresolvable differences it has with ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

A new experiment will test the notion that gravity, one of the fundamental forces in the physical world, relies upon quantum physics to work. If so, it would further indicate the centrality of quantum ...

Time feels like the most basic feature of reality. Seconds tick, days pass, and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
