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 ...

Dimensions beyond the four we’re familiar with could solve a host of problems in physics and cosmology. Columnist Leah Crane ...

Could reality be made of more dimensions than those we perceive? The question has consumed some of the most brilliant physics minds for over a century, from unifying space and time into spacetime by ...

Interferometry has become an indispensable diagnostic tool in plasma physics, enabling the precise measurement of electron densities and detailed imaging of plasma behaviour. By utilising the ...

The laws of physics stay the same no matter one’s perspective. Now this idea is allowing computers to detect features in curved and higher-dimensional space. Computers can now drive cars, beat world ...

A new underground facility called DUNE, which will accelerate particles for 800 miles between Illinois and South Dakota, could reveal the hidden dimensions of the universe, new research suggests. When ...

Uncertainty affects the accuracy with which measurements can be made in quantum physics. To reduce this uncertainty, physicists have learned to "squeeze" certain measurements. Researchers are now ...

We experience three spatial dimensions in nature: length, width and height. In addition, we perceive time as a fourth dimension. But some theoretical physicists have speculated that “extra” spatial ...

Classical and quantum dimensions are fundamental quantities in information processing. In particular, the security of many cryptographic schemes 1,2,3 crucially relies on the dimensional ...
