The fundamental forces of nature are intimately related to corresponding symmetries. For example, the properties of electromagnetic interactions (or force) can be derived by requiring the theory that describes it to remain ...

Gravity is a pretty awesome fundamental force. If it wasn't for the Earth's comfortable 1 g, which causes objects to fall towards the Earth at a speed of 9.8 m/s², we'd all float off into space. And without it, all us terrestrial ...

Studies of beta decay, which involves an electron and antineutrino being emitted from a nucleus, can reveal new properties of the weak nuclear force—one of the four fundamental forces in the universe. Scientists performed ...

When we look out at the universe – even with the most powerful of telescopes – we can only see a fraction of the matter we know must be there. In fact, for every gram's worth of atoms in the universe, there is at least ...

Precise information about the magnetic properties of nuclei is critical for studies of what's known as the 'weak force.' While people do not feel this force in the same way they feel electricity or gravity, its effects are ...

(Phys.org) —A trio of physicists is suggesting in a paper they've published in Physical Review Letters, that results from an experiment run in the early 1980's places constraints on the idea of a dark photon in theories ...
