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 ...

A scientific experiment has produced evidence researchers believe points to a previously undiscovered fundamental force of physics. All interactions in the natural universe - from a hand catching ...

A look at how the meaning of "fundamental" shifts when you consider different areas of physics.

We all know about the four fundamental forces of nature: gravity, electromagnetism, and the weak and strong forces between atoms. But could there be a fifth force still waiting to be discovered? A ...

Gravity, electromagnetism and the strong and weak nuclear forces are the four fundamental forces known to physics — but researchers have made many as-yet unsubstantiated claims of a fifth.

There are many questions still to be answered about the standard model of particle physics, which describes the fundamental forces and interactions of nature. On page 516, Martinez et al. 1 report ...

Gravity, electromagnetism and the strong and weak nuclear forces are the four fundamental forces known to physics—but researchers have made many as-yet unsubstantiated claims of a fifth.

University of Texas physicist Steven Weinberg won the second physics award, a Special Breakthrough Prize honoring his "continuous leadership in fundamental physics, with broad impact across ...

GUTs, for example, seek to merge three of the four known fundamental forces: the strong, weak and electromagnetic interactions (gravity is the fourth).

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 ...
