In a cavernous tunnel beneath the French–Swiss border, physicists have briefly recreated conditions that existed microseconds ...

The interaction between electromagnetic waves and plasma is a subject of considerable interest due to its relevance in aerospace, telecommunications, and stealth technologies. When electromagnetic ...

In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles ...

In the quest to unravel the mysteries of the universe, physicists are revisiting a 150-year-old theory that could illuminate why matter prevails over antimatter. This knot hypothesis, originally ...

What if the next new theory of the universe didn’t come from a human mind, but from an artificial one? In a development that has left the scientific community both awestruck and unsettled, artificial ...

Our universe may be fundamentally unstable. In a flash, the vacuum of space-time may find a new ground state, triggering a cataclysmic transformation of the physics of the universe. Or not. A new ...

Our universe started with a bang that blasted everything into existence. But what happened next is a mystery. Scientists think that before atoms formed—or even the protons and neutrons they’re made of ...

A process important to black holes and supernovas has for the first time been demonstrated in a laboratory. A promising method for producing and observing on Earth a process important to black holes, ...

Physicists have used a machine-learning method to identify surprising new twists on the non-reciprocal forces governing a many-body system. The work is one of the relatively few instances of using AI ...

Researchers have uncovered a process in the swirling masses of plasma surrounding black holes and neutron stars that can cause previously unexplained emissions of light and heat. These findings can ...
