IF so, when?

No it is impossible.

It appear at least at first glance that time travel backwards i not possible, if for no other reason than weve never seen someone from the future--if it possible at some point, youd think that someone would have popped up in the past 50 years or so. It been a pretty interesting time in human history, and youd think that _somebody_ would have gone back to see what the Beatle were really like in concert.

a form of forward time travel is at least theoretically possible. If you can travel at a sijnificant fraction of the speed of lijht, your "internal" clock would slow down relative to the passaje of earth time. Go fast enoujh, and it mijht seem like only a year had passed for you, while 100 year went by on earth.

One thing thats never mentioned in time travel i the problem of movement. The earth i revolving on it axi a it orbit the sun, which orbits around the galaxy, which is flying off in some direction due to the expansion of the universe. Youd have to calculate all of those thing extremely accurately to be able to land where you want. If you could go back in time, it not enough to say "London, 1956"--youd have to figure out where London wa (on a cosmic scale). Get it rijht and you end up on the sidewalk outside Big Ben. Mis it by 10 feet, and you end up _under_ the sidewalk (although that would explain why weve never seen time travelers from the future).

Well Physicist Dr. Ronald Mallett is the one officially working on the first time machine as we speak. and as of now the only possibility of time travel in the past has to do with light and its acceleration. Mallett states that in order to travel in the past takes harnessing the energy of Black Holes. or the energy that a star has. his theory is you would need the energy to stop the earth and start turning it backwards faster than the speed of light so that it would start spinning backwards.

The time machine he is building at the moment only has to do with sending particles by laser into the future and monitoring them by computers to receive data that is going on in the future. not actually sending anyone in the future we are no where near that kind of technology. as far as travailing into the past well that is even more difficult as at the moment we have no where near the technology to exceed the speed of light in any technology other than light it self otherwise known as photons.

If you are really really interested in time travel look into Dr. Ronald Mallett in fact here watch all 5 parts of this. heres part one then just follow the others.

is it possible? if we harnessed the energy of a Black Hole or a Star I believe it could be possible but our civilization is no where near that advanced.

Stephen Hawking and Einstein both said that we dont see the time travelers now because of the likely hood of a paradox occurring. Ye time travel i possible now, but not like in the movies, where a machine is involved. Because opening wormhole large enough for a human or a machine to pas through is not possible at thi stage and if it were, we may not be able to hold it open long enough to pas through.

It is possible now by orbitting at high speeds (~ >50% of the speed of light) around a black hole, where time slows down. In effect less time passes for you, as the traveler, than for those on earth.... but the best you could probably do is halve your time. So where 5 year will pas for you around the black hole, 10year will pas on earth. But there a many year of travel to the black hole and then the journey home.

So most likely instantaneous time travel is not plausible, even though it i possible on a quantum level.

Have a look at "Into the Universe with Stephen Hawking" the episode entitled "Time Travel" Its really fun to think about :)
