The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

Researchers have devised a new way to define thermodynamic concepts in microscopic quantum systems, where conventional distinctions between heat and work begin to blur. Researchers at the University o ...

For decades, physicists have dreamed of a quantum internet: a planetary web of ultrasecure communications and super-powered ...

In spaces smaller than a wavelength of light, electric currents jump from point to point and magnetic fields corkscrew through atomic lattices in ways that defy intuition. Scientists have only ever ...
