Fundamental interactions, also known as fundamental forces, are the interactions in physical systems that do not appear to be reducible to more basic interactions. Much like the periodic table of ...

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 ...

About 20 years ago, a physicist had an idea to reveal insights about a fundamental but enigmatic force at work in some of the most extreme environments in the universe. These environments include an ...

In recent years, a group of Hungarian researchers have made headlines with a bold claim. They say they’ve discovered a new particle — dubbed X17 — that requires the existence of a fifth force of ...

I'm teaching introductory Newtonian mechanics again this term, and as always I find myself fascinated by bits of the subject that my students are largely indifferent to. This week, that collided with ...

Researchers may be on the brink of discovering evidence of a fifth fundamental force. As far as we know, at the most basic level, the universe is made up of fundamental particles and controlled by ...

The Selection Committee of the Breakthrough Prize in Fundamental Physics today announced a $3 million Special Breakthrough Prize in Fundamental Physics for Steven Weinberg, commending his “continuous ...

DEEP in a disused zinc mine in Japan, 50,000 tonnes of purified water held in a vast cylindrical stainless-steel tank are quietly killing theories long cherished by physicists. Since 1996, the ...

There may be a fifth fundamental force of the universe that we haven’t documented yet — and, according to new research, our best bet of uncovering it may not lie in deep space, but in objects ...
