Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

What could be more familiar than gravity? Drop something and gravity pulls it to the floor, right? And in school we learn that gravity is what guides the moon in orbit around Earth, and Earth in its ...

For more than a century, physicists have been trying to reconcile the smooth geometry of gravity with the jittery ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

When I was five years old, my family moved into a 1930s semi-detached house with a long strip of garden. At the end of the garden was a miniature orchard of eight apple trees the previous owners had ...

As far as physicists have been able to determine, nature speaks two mutually unintelligible languages: one for gravity and one for everything else. Curves in the fabric of space-time tell planets and ...

A theoretical physicist in England has won a prestigious award for her work on the theory of massive gravity, which could explain why gravity hasn’t constrained the rapid expansion of the universe.

The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...
