Description: Is there a fifth force? What is the fifth force? In physics, there are four observed fundamental forces which form the basis of all known interactions in nature: gravitational, electromagnetic, strong nuclear, and weak nuclear forces. However, there are theories which propose unknown physics, a fifth force, to explain anomalous observations that do not fit existing theories. Dr. Yu-Dai Tsai joins John Michael Godier to discuss how it may be possible to use asteroids to probe for this hidden fifth force of nature.
