ATLAS Experiment searches for new symmetries of nature

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 ...

How strong is the force of gravity on Earth?

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 ...

Improved tests of the weak nuclear force from beta decay

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 ...

SLAC theorist explains quantum gravity

Our world is ruled by four fundamental forces: the gravitational pull of massive objects, the electromagnetic interaction between electric charges, the strong nuclear interaction holding atomic nuclei together and the weak ...

The universe as we know it

Sitting in a small French bistro across from Pershing Square in downtown Los Angeles, Clifford Johnson held the pumpkin-hued drinking straw parallel to the table.

Using an electron to probe the tiny magnetic core of an atom

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 ...

CERN researchers confirm existence of the Force

Researchers at the Large Hadron Collider just recently started testing the accelerator for running at the higher energy of 13 TeV, and already they have found new insights into the fundamental structure of the universe. Though ...
