Add Yahoo as a preferred source to see more of our stories on Google. In the very early, very hot moments of the universe, the electromagnetic and weak nuclear forces were actually the same force—the ...

As far as we know, at the most basic level, the universe is made up of fundamental particles and controlled by four fundamental forces. The Standard Model explains these fundamental particles and ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

DURHAM, N.H.—Research from a team of physicists at the University of New Hampshire is advancing the understanding of how protons, which comprise 95% of the mass of the visible universe, interact with ...

An ambitious new collaboration promises to expand our understanding of what some physicists have called the “glue” that holds the universe together — the strong nuclear force. “One of the fundamental ...

Gravity is the most familiar of nature’s forces. It keeps our feet planted on the ground and dictates the movements of ...

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 ...
