Time travel could happen within 100 years

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.

(Bold mine) The idea is, if time for the astronaut is ticking slower than time for Joe on the Earth, Joe is racing into the future faster than the astronaut. That's my view,, that the high velocity time dilated guy is lagging Behind those below.... but but Harte said ! that Sergei Avdeyev and the Apollo astronauts were the ones traveling forward in time and that " At very high speeds, you can jump ahead 10,000 years in a few seconds." but ya, it's still now in both places or we'd never see them again .

It's a matter of perspective. When the astronaut lands back on earth, more time has elapsed on earth than for the astr... [More]

ah , ok thanks StarMountainKid... (that's what i thought) the 'time travel' , if any, takes place when they slow down in velocity and catch up to, and rejoin, earth time. Weird that time passes at differing rates according to velocity .... (relative to what?) (C?) Kinda confusing when everything is flying around the universe at different velocities? .. what time is it buddy ? .....um.. that depends. Is that why the group Chicago sang.. " nobody really knows what time it is " ?

It's a simple law of physics, the closer to light speed you get, the slower time gets and it's linear. If you are in a plane going 300 MPH then time slows down a tiny little bit. If you're in the SR-71 going 3500 MPH then time slows down a little more and so on. It's the relativity thing Einstein talked about.

Explained in the simplest terms, moving clocks speed up or slow down relative to chronometers at rest. Were the astronaut in StarMountainKid's example to have exceeded the speed of light, his watch would run in reverse as he traveled backward in time. I dont believe you can travel backwards in time using time dilation either. If you travel faster than sound for instance do you hear everything in reverse? Clearly the hypothesis is flawed.

That explanation was based upon special relativity.It makes sense to me when I gaze at distant stars. Their light takes so long to reach us that that our viewing them is witnessing light years into the past. Thence, the notion of a chrononaut's having to go faster than the speed of light for him to travel back- ward in time.

If any future time travelers are reading this, please message me.

You are correct in that if you exceed light speed you don't travel back in time. You leave the universe if you go faster than light. The entire universe. And you don't come back if you slow down. It's a simple law of physics, the closer to light speed you get, the slower time gets and it's linear. If you are in a plane going 300 MPH then time slows down a tiny little bit.
