Physicists have predicted that time travel and teleportation could become a reality this century.
Scientists from Imperial College London and the University of Glasgow have put forward their predictions for when we might see popular science fiction technologies in the real world.
One of the most promising upcoming examples is an invisibility cloak, something that researchers have been experimenting with for some time. While we have yet to see one as good as that used by Harry Potter, the potential exists for an effective invisibility mechanism to be available within as little as 15 years.
Another technology that a lot of people would like to see is teleportation. While progress has been made teleporting individual particles short distances it could still be several more decades before we can teleport people from one place to another in an instant.
"Teleporting a person, atom by atom, will be very difficult and is of course a physicist's way, but perhaps developments in chemistry or molecular biology will allow us to do it more quickly," said Dr. Mary Jacquiline Romero. "The good thing about teleportation is that there is no fundamental law telling us that it cannot be done."
Perhaps the single most tantalizing science fiction concept however is time travel. Despite doubts over whether such a thing is even possible, some scientists believe that it probably can be done.
"I would say we are looking at 2100 as a very optimistic timescale for travelling weeks into the future," said author Colin Stuart. He does admit, however, that it will be a very difficult thing to achieve.
