The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but there’s still a long way to go toward understanding this fundamental force. In September, ...

Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to physics ...

Using gold flakes, salt water, and light, scientists have made the universe’s invisible binding forces visible in color. The discovery opens new possibilities for studying how matter organizes itself ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery of dark matter. With new approaches to measurement in the quantum realm, ...

The gravitational wave transmits an energy packet to the light wave. It should be feasible to observe both phenomena, namely, the stimulated emission and absorption of gravitons, although this would ...
