Description:
Time travel is possible! But how? Hollywood rarely gets the science right in “time warp" movies. However, an excellent example of fusing of multiple pasts into a changing present, of altering history as it were by weaving different paths from the past into one changed present, is the excellent film Frequency, which starred Dennis Quaid and Jim Caviezel. That once, Hollywood hit the quantum nail right on the head. Nothing that happened in Frequency is theoretically impossible. Just as Schrödinger’s cat can divide and take multiple paths into the future, multiple strands from different pasts can weave into one present. We are talking about moving forward or backward in time. But, really, how is time travel possible? There are a great many writings on the conditions necessary for time travel, on the seeming paradox of what happens if one goes back in time and kills one's grandfather, of time travel using black holes and Einstein-Rosen bridges. But few works conceptually explain how time travel operates. How is time travel possible? Recent discoveries in quantum physics (the study of the physics of sub-atomic particles) and in cosmology (the branch of astronomy that deals with the universe taken as a whole) shed much light on how mind interacts with the universe, including the phenomenon of time travel and an explanation of what is time travel.
