Known as the Standard Model, this theory describes the elementary particles and three of the four fundamental forces that serve as the building blocks for our world (see the Elementary Particles ...

Gravitons are hypothetical subatomic particles, considered key components in a theoretical quantum theory of gravity. Some ...

In particular this theory would unify our understanding of all the fundamental physical forces in our universe. There are four such forces that physicists know of: gravity (which keeps planets ...

There are four fundamental forces in the universe: gravity, electromagnetism, the weak and the strong interaction. While general relativity describes gravity, quantum theory deals with the other ...

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 ...

These four fundamental forces exist between fermions (quarks and leptons). They arise from the exchange of bosons. Bosons are the 'force carrying' or 'force-mediating' particles. If a fermion ...

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 ...

"These two binding energies are the result of three out of the four fundamental forces in physics: electromagnetism, the strong nuclear force, and the weak nuclear force. This is in contrast to ...
