The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

A force that couples electrons and neutrons could be an addition to the Standard Model, and a new study places an upper limit ...

A subatomic particle called the muon is wobbling far more than leading physics models can explain. Its unusual behavior could be evidence of a fifth force of nature or a new dimension. Scientists ...

The Standard Model of physics currently accounts for three of the four known fundamental forces of the universe, and all three have their own particles to explain them.

Every action in our world is powered by a "force of nature." Currently, there are four main forces that scientists cling to; ...

Scientists close in on a fifth force as they discover a mysterious subatomic particle disobeying the laws of physics Physicists observed the 'peculiar wobble' of subatomic particle called a muon ...

The team’s orb rolled vertically at a rate of about 0.5 millimeters per second. Regardless, Mitra and colleagues wrote that their observation “challenges our basic understanding of physics,” with ...

It is right to say there are four fundamental forces in everyday speech. But the true picture is often richer than widespread notions, for it is the equations that best capture the tapestry of nature.
