Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively simple question: why? One answer, first sketched a century ago and refined ...

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 ...

A 2,000-page monograph series proposes a new conceptual framework connecting quantum physics, gravitation and cosmological evolution.

It isn’t often that physics produces news that diverts the mainstream media from politics, crime and sports. But, now, in the space of four years’ time, physicists have twice elevated the intellectual ...

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

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 ...

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.
