The physics of the microrealm involves two famous and bizarre concepts: The first is that prior to observation, it is impossible to know with certainty the outcome of a measurement on a particle; ...

Record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle.

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 ...

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 ...

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 ...

Superposition on a massive scale: illustration of a mass-quantized black hole that was created using NightCafe Creator AI. (Courtesy: University of Queensland) Quantum superposition is not just a ...

Wouldn't it be fascinating to live in New York and London at the same time? In the standard of everyday life, this is equivalent to daydreaming or sheer fantasy. Nevertheless, this is a perfectly ...

Applying the superposition principle to a photon's motion can lead it in two different directions at the same time. If a different order of operations is applied in each path, this can be used to ...

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 ...

Scientists created quantum superposition states at temperatures up to 60 times hotter than their environment, challenging the assumption that quantum effects require extreme cold. This discovery could ...
