Physicists have predicted that personal space travel will be available by 2015. Invisibility cloaks (the Harry Potter ones) might become a reality by 2030—in fact, scientists have already developed many technologies that can make something invisible. A cloak is much harder to produce because the fibers in one have to be incredibly fine. Teleportation could be an everyday thing by 2080. Physicists have already invented reliable methods of teleportation, but only with electrons, not atoms. Time travel could exist by 2100. It has already been accomplished, but the record is only 0.02 seconds into the future. One would have to travel for 6 months at 10% the speed of light through space to jump 1 day into the future.
