Despite keeping us grounded and warping light that travels through space, gravity is actually quite a weak force. The smaller the mass, the less gravity appears to have any pull, until at quantum scales it appears to have no force at all. Now, physicists in England and Europe have measured a tiny—but apparent—gravitational pull on…
