At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

A cluster of 7,000 sodium atoms has just been coaxed into behaving as a single, ghostly wave, stretching quantum weirdness into a realm that starts to look uncomfortably like everyday matter. Instead ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

Researchers at Santa Clara University have developed a comprehensive mathematical framework to rigorously analyze and predict ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...
