Classically the two possibilities are independent, but quantum mechanically they affect each other. These models presume the existence of one But if no one observes the particle, it exhibits the behavior of a wave that can inhabit all possibilities—including somehow passing through both holes at the same time. Wells, science fiction buffs have gone gaga over the idea of traveling through time. Then, traveling through that field (which may or may not involve physical movement as it's space time field) you would actually go backwards in time instead of forwards. For centuries, scientists regarded Berkeley's argument as a philosophical sideshow and continued to build physical models based on the assumption of a separate universe “out there” into which we have each individually arrived. Free to explore the universe and ask the big questions, such as: is time travel possible? In 2011 Light speed limitations may not exist in a parallel universe, and the paradoxes that keep us from traveling back in time would be null and void if we could jump into a different historical timeline. Richard Gott, also rely on Einsteinian relativity to provide the necessary distortion of space and time, but both are more accommodating to the physical comfort of . However, there is also the possibility that one travels to a different universe that is simply the same as your own. The two newer time machines, one proposed by Aharonov and the other by Princeton physicist J. One can "travel" into the future by going close to the speed of light, but that is not immediately going from one "time continuum" (so to speak) to another, just using "relative time" (Einstein's relativity) to your advantage, but still passing Finally, you don't travel into a different world, still this universe. Hawking says: "Although I cannot move and I have to speak through a computer, in my mind I am free. Are we limiting ourselves to our understanding only of the laws and possibilities of our universe, and leaving out of the equation other realities, other universes, with other laws and forces, paradoxes and limitation, possibilities and potentialities, far beyond our own? (Phys.org)—If an object traveling through spacetime can loop back in time in a certain way, then its trajectory can allow a pair of its components to be measured with perfect accuracy, violating Heisenberg's uncertainty principle. (PhysOrg.com) -- The possibility of going back in time only to kill your ancestors and prevent your own birth has posed a serious problem for potential time travelers, not even considering the technical details .
