Physicists are building detectors so sensitive that they may succeed in unraveling one of the greatest mysteries in modern physics: the true nature of dark matter.

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...
