In the grand tradition of the previous volume of this devastating series, further arguments against the validity of special relativity are presented, this time by demolishing the experimental "evidence" of the long-lived muons. Also, an experimental method to disprove the relativity of simultaneity is presented. Unlike the previous volume, this one also brings death and mayhem to general relativity by dragging the famous twins out of the special theory and into the general where they belong, and slaying them there. It also tackles spacetime curvature, and receives a visit from Einstein himself, via a paper from 1918, in which the noted physicist attempts to rebut some of the arguments made in the present volume.
