After 25 years, Brookhaven National Laboratory’s Relativistic Heavy Ion Collider—the U.S.’s largest particle collider—has ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

A rare black hole explosion accounts for an “impossible” neutrino detection, say UMass Amherst scientists, possibly hinting ...

Once this effect kicks in, the black hole discharges rapidly and explodes. Crucially, the UMass team calculated that this ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles zinged around at light speed, creating a "quark-gluon plasma" that lasted for ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.
