A Question about Time Travelling

[FrankCastle]

I watched a movie a while ago called Primer and while it addressed some fascinating time travel concepts the whole idea of going back in time is totally impossible,even on a theoretical level.Here's why.

In movie's when people go back in time they encounter alternate versions of themselves.How is this possible when only ONE version of you exists.
If you're talking alternate universes then you cannot meet your other self if you do go back in time since you both exist in separate realities.

Primer tries to address this making sure your real self and your alternate self do not meet so as not to alter reality, but still this is completely implausable.

Any ideas?

Time travel IS possible. Didn't Superman do it in the second movie?

So did Doc and Marty, and also Will Smith... Five movies is too many to be a coincidence.

I think it could be possible, in the not so near future. But everyone will look back at us and our ideas and movies and think : 'Idiots'.
Read Steven King's The Dark Tower series for an interesting idea regarding timetravel and the effects it could have. (The first 3 books will be enough)

Welllllll, read up on quantum physics and you will see it is not as simple as that. If some theories hold there are more dimensions and states of energy.

Time travel to the future, certainly possible we know how to do this. To the past, highly unlikely.

Time is not linear as far as I remember, it is relative. The problem is cause is needed before effect.

Time travel won't be possible during my lifetime. I made a mental note that I would visit my teenage self if I invent a time travel machine or at least steal one if I didn't. Or maybe in the future I get killed while attempting to steal it.

*new mental note* Do not steal time travel machine.

Sorry im not following your statement and what it has to do with what i said, time slows down near large objects. Travel out to a black hole circle the black hole for x amount of years. Return to earth and time will have advanced 2x.

Nogard? Any input?

Hey it works

Time is relative, an example I've heard of is to think about 3 points of a triangle, A, B & C now time is governed by the speed of light (according to something I saw on Discovery channel a while back )If you follow the speed of light from point A to B you are traveling normally, BUT If you travel faster than the speed of light from point B to C you are effectively going ahead in time, as you are beating light to its destination, but if you ask me that's looking it at face value as you are only beating the clock, not actual time/space
Was this guy in the clip explaining it

If anyone ever does manage to travel through time, please attend Stephen Hawking's party.

built a time machine going back in time a few minutes and will post if it works

Unicorns flying backwards go back in time. Pity they're extinct.

I think it could be possible, in the not so near future.

If travelling back in time was possible in some future date then we'd be seeing all these time travellers from the future in our own time. QED.

Another interesting paradox

I give you nogard for your examination? Quite possibly it has travelled back in time from an era where babies are fed hallucinogenic milk?

nogard travelled back 12 Monkeys style. Side effects include insanity.

I just quoted you as I agree "time travel" to the future can be done. But traveling to the past is very unlikely.
