![]() Gravity, however, closes the bridge before it can be traversed.īernard Schutz, Gravity from the Ground Up (Ĭambridge, 2003). In particular, it makes travel appear possible from one side of the bridge to the other. Furthermore, the bridge is misleading in that it contains none of the gravity, and resulting dynamics, of a black hole. The Einstein Rosen bridge applies only to black holes that were cast into the initial structure of the universe, not to black holes that formed as the result of stellar collapse. A picture of the Einstein Rosen bridge can be found as Fig. The particle problem in the general theory of relativity,” Phys. Those authors, in a paper more related to classical mechanics than to relativistic gravity, state “… it is hard to argue that the conceptual analogy of a marble rolling on a warped fabric does not benefit the beginning student of general relativity.” We make precisely that argument here, and find it easy as well as compelling. This article takes a strong stance in direct opposition to that inĬircular orbits on a warped spandex fabric,” Am. 3, but in the following subsection (“A Few Caveats”) he points out the shortcomings of the analogy and the ways in which it may be misleading. Greene presents the rubber membrane bowling ball analogy in a subsection of Chap. ![]() An excellent example of this can be found in The probability of confusion is near certainty. Among other wildly misleading aspects of this “model” is the fact that it is Earth gravity pulling the bowling ball down and hence deforming the rubber sheet. ![]()
