What are the chances of there being other universes, with different life forms?
Steve & Deja: We are absolutely certain that other life forms exist in our Galaxy and not just Carbon based. In the book we use the concept of silicon and robotic life forms to illustrate this very point. As to whether there are other Universes, presently there is no strong evidence either way. However the physics and mathematics do not preclude multiple Universes and their inter-relationships. A maxim in physics is “if it’s not precluded, then it must exist.” And of course other life forms will be present in other Universes.
