When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the ...

Every time I write about particle physics, I encounter a moment of uncertainty about a quantity that, at first glance, ought to be clear. How many kinds of elementary particles should I say there are?

Stardust Solutions says its tiny spheres can reflect the sun’s rays without harming people or the environment. Critics say private companies have no business altering Earth’s atmosphere. An enclosed ...

Light is one of the most studied phenomena in physics — and yet it still surprises. At the Princeton Plasma Physics Laboratory, researchers running mathematical calculations on individual photons have ...

A pair of rare particles produced in high-energy proton collisions may be the clearest evidence yet that mass can emerge from empty space. The finding could shed light on one of the biggest puzzles in ...

When you drill down into the very fabric of reality—where elementary particles make up the matter that is you and me and everything around us in three-dimensional space—things get divided nicely into ...

Scientists discovered “magic” top quarks at CERN’s Large Hadron Collider, demonstrating how the facility has evolved to support quantum computing research. Researchers at ATLAS observed ...

In a rare global collaboration, scientists from Japan and the United States joined forces to explore one of the universe’s deepest mysteries — why anything exists at all. By combining years of data ...

A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic particles. What happens to these particles within atoms would stay unexplained ...
