High-energy particles rain down on Earth constantly, but scientists have now detected a doozy: a neutrino blasting in from ...

Or, as Neil put it: “If a single atom was the size of a human being ... One popular theory suggests that the elementary particles themselves are made up of vibrating strings that are about the size of ...

A hydrogen atom can be raised into an “excited ... However, note that our model is not an exact representation because elementary particles do not undergo births or deaths.

Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal ...

A huge detector in the Mediterranean Sea spotted the most energetic neutrino from space to date. The particle could shed light on the universe’s most extreme phenomena.

Astronomers using a giant network of sensors, still under construction at the bottom of the Mediterranean Sea, have found the highest-energy cosmic “ghost particle” ever detected.

Join six leading experts to find out everything we know about the subatomic universe. Take a deep dive into the building blocks of the universe, from the atom to the standard model, and learn how ...

Instead it has helped explain why many elementary particles have the masses that ... Even if we could extract every single atom, he says, there would still be so many things remaining, such ...

Particle physics is the study of the elementary building blocks ... which mediate forces between the other particles. Antihydrogen is the simplest atom of pure antimatter. Measurements of a ...

The waves were manifested in a kind of “virtual field” of some kind that spread throughout the system, and they acted to “pilot” the particles. In the BKS picture, an excited atom about to ... of ...
