The world of quantum mechanics, where particles can be in two places at once or entangled with each other across vast distances, sounds spooky to us living in the macroscopic world of classical ...

It's driving me nuts. Is the double bond constantly changing between all possibilities fast enough that it shortens the bond length for all, or are all the double bonds existing in all possible states ...

Interrelated Superposition and entanglement can be observed independently of the theoretical framework used to explain them. (Courtesy: iStock_Traffic-Analyzer) When a forest loses its trees, it also ...

In the world of quantum physics, another record appears to have just been broken. In a paper listed on the preprint site ArXiv, researchers at the University of Science and Technology of China claim ...

Red and blue: a photon of two colours has been made. (Courtesy: iStock/-strizh-) Individual photons have been put into a quantum superposition of two different colours by a team of physicists in the ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. When I teach or give talks about relativity, one of my regular angles ...

Topological defects are encountered in fields ranging from condensed-matter physics to cosmology. These broken-symmetry objects are intrinsically local, but theoretical work now suggests that ...

PHYSICS HAS A problem. In general relativity, time is entwined with space. It is relative, depending on speed or gravity. In quantum mechanics, however, time is an absolute. It is a smooth background ...
