Chapter Nine: The Smoking Gun, Experimental Signatures Summary and Analysis

String theory actually predicts gravity—if it was not apparent in the world around us, physicists would be able to deduce its existence using string theory. Though it is perhaps the most promising theory in the history of physics, the current inability of string theory to be experimentally tested is a big setback. Traditionalists in physics want theories to be experimentally testable, as experimentation has been the way to test theories for the last few centuries. These objects theoretically existing at the Planck length are about 17 times smaller than the current limit of magnification.

The elementary particles fall into three family groups which possibly correspond to specific holes in the Calabi-Yau shapes, according to their string vibrations. The three family groups are a reflection of the geometric shape...
