What is our Universe made out of? At a fundamental level, to the best of our knowledge, the answer is simple: particles and fields. The type of matter that makes up humans, Earth, and all the stars, ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. But not all particles are like the electron. For some of them, even ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Physicist Richard Feynman invented them to describe the interactions between real particles. This article was originally published at The Conversation. The publication contributed the article to Space ...

It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more ...

The physicists who came to our presentation at the 2010 Neutrino conference in Athens, Greece, probably expected us to put to rest a controversial finding from a decade prior. Instead we left them in ...

For three decades, researchers hunted in vain for new elementary particles that would have explained why nature looks the way it does. As physicists confront that failure, they’re reexamining a ...

Forget about turtles; for all practical purposes, it’s really particles all the way down. Consider the seemingly simple matter of their size, the very thing that makes them so alien. We’re typically ...

Discover 'ghostly' particles and quantum depletion. A new study makes the first observation of 'ghost particles' from Bose-Einstein condensates via 'quantum depletion': particles expelled by ...
