It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental nature of gravity still eludes our best minds - but those ...

While the existence of extra dimensions is a cool idea, it's currently not supported by any evidence ...

Scientists have measured gravity at an extremely short distance, in what they hope will tell us more about extra dimensions. The rest of this article is behind a paywall. Please sign in or subscribe ...

A recent study has made strides toward solving one of physics’ biggest puzzles: including all known particles and interactions into the theory of quantum gravity. The solution is to modify the quantum ...

Physicists wonder if our universe contains hidden extra dimensions. These dimensions could explain why gravity is so weak. They might be curled up so tightly we cannot see them. High-energy particles ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...

The original version of this story appeared in Quanta Magazine. When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain.

The solution as to why gravity is so weak may come from taking a closer look at the Higgs boson. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.
