It was a bold thought experiment: that only one electron makes up the entire universe. The most famous conversation about it took place between Richard Feynman, PhD, and John Wheeler, PhD, both ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

The race to develop a virtual scientist—an AI creation that conducts every stage of research, from idea to publication—has ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

Sam Baron receives funding from the Australian Research Council. The Matter of Everything tells the history of physics through experiments. Any book about the history of science for a general audience ...

The idea of relative motion is an aspect of the theory of relativity (strictly, it’s Galilean relativity, rather than ...

trace their origins to the fundamental fuzziness of the subatomic world. Inflation created tiny lumps in the distribution of matter and tiny variations in the temperature of the cosmic microwave ...

A deceptively simple experiment that involves making precise measurements of the time it takes for a particle to go from point A to point B could cause a breakthrough in quantum physics. The findings ...

If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to each other. And if information could leak between outcomes, it could mean ...

FOR an experiment designed to help us find evidence of other universes, it looks surprisingly modest. As Zoran Hadzibabic walks me into the lab, it feels more like a classroom, complete with linoleum ...
