time travel to different time periods the past and future

[TomA]

is it possible to travel through time i won't tell you why or give any details just that it involves the future and the fate of north america a couple centuries from now i want details on time travel if i sound like a loonatic then beleive what you want but ive heard of a field in england that took a man back a 1000 years and there is some proof but there is too much to name it all anyway please tell me

wow, sounds like you had a bad dream. well time travel could be possible i suppose. here's what i understand and make of it:

light is photons.
photons travel at speed c the speed of light.
photons are said to disapear around speed c.
it could be said that beyond speed c, they disapear, and when they drop below speed c, they appear.
as an object (made of atoms) approaches speed c, its relative time slows down.
at speed c, relative time stops.
beyond speed c, the object might disapear like photons.
where does it go?

well, if time slows down the faster you go up to 0 relative time at speed c, maybe when photons disapear they are travelling back time, then when they slow down they temporarily settle in a parallel world.
maybe the object would do the same? as for travelling forward, just ride slightly below light speed and you will age incredibly slower than anyone else therefore in 1 hour you might travel 2 years forward.

Look up Dr Stephen Hawking. He's the guy who can probably explain it best.
I've heard things like: traveling back in time is not likely, but we could travel into the future if we go near the speed of light when time would slow down.
