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 ...

Atoms are usually made of protons, neutrons and electrons. These are made of even smaller elementary particles. Elementary particles, also known as fundamental particles, are the smallest particles we ...

Today's physicists are struggling with a quandary. They have accepted two separate theories that explain how the universe works: Albert Einstein's general theory of relativity, which describes the ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you take any amount of matter, no matter how small or how large, ...

Without elementary particles, there'd be no X-Ray machines, no Internet and no electricity. Because some elementary particles penetrate matter without destroying it, they're a boon for scientific and ...

Why do neutrinos, these elementary particles, sometimes seem to act in such a puzzling way? For decades, physicists have been faced with this puzzle, observing behaviors that do not fit ...

In the 1990s, the Liquid Scintillator Neutrino Detector (LSND) in Los Alamos, New Mexico, found a weird anomaly during its experiments on tiny elementary particles called neutrinos. It found far more ...

The atomistic paradigm of high energy physics cannot anymore be dismissed because the proposed elementary particles are too many (and, hence, it is claimed, they do not provide a simple account of ...

Every second, without you knowing it, thousands of billions of invisible particles pass through your body. These cosmic objects travel across the Universe from distant sources, moving at ...
