Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. Gravity holds stars together and keeps us on the ground. The electromagnetic force ...

They are gravity, electromagnetism, the weak nuclear force that causes particle decay, and the strong nuclear force that binds quarks into atoms. Together, these have become the standard model of ...

In the very early, very hot moments of the universe, the electromagnetic and weak nuclear forces were actually the same force ...

That at least is the case with the strong nuclear force, one of four fundamental forces of nature (the others being electromagnetism, gravity and the weak nuclear force). The strong force holds ...

Researchers hypothesize a fifth force of nature that could explain the intricate relationship between dark matter and dark ...

And the reason could be evidence of a new, fifth force of nature. Currently, there are four known forces of nature: gravitational, electromagnetic, and the strong and weak nuclear forces.
