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 ...

Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively ...

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 ...

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 ...

It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. But now, scientists at the University of Oxford have found that ...

Chalk up another win for the Standard Model, the remarkably successful theory that describes how all the known fundamental particles interact. Physicists have made the most precise measurement yet of ...

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 ...

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at ...

Steven Weinberg always knew he wanted to be a theoretical physicist,asking big questions about the universe and seeking out answers. It started in high school, when he received a hand-me-down ...
