Time Travel, is it possible?

I dont know any technical stuff about this topic, it's really not one of my strengths. But as i said, i believe almost anything is possible, so why not? Maybe there's a way to create the dreamed "time machine", but i dont think you could travel to the future, only to the past.

Discuss.

As in my thread, Special Relativity states that the faster an object moves through space, the more time slows down for observers traveling with the object. If traveling at speeds close to the speed of light, it could be sufficiant enough so that what might feel like an hour to you, could be 100 years to everyone else back on Earth. Of course this is not only beyond our technology, but almost beyond our comprehention. However from experiments, to the fraction of a nano second, it appears to be true.

Sure, we are all time travelers. All of us are moving into the future second by second.

Intentionally altering your world line relative to everything else is very easy to do. Just hop aboard a commercial airliner. The time dilation is small but it can be measured just at the speed of a jet liner.

Going back in time is a whole other question. Personally, I do not think it is possible and still be able to stay in the same world line. If that be the case then there would have to be an infinite number of world lines (parallel universes) where every conceivable outcome is accounted for in order to avoid time related paradoxes. Supergravity predicts a possible 11 dimensions of existence. Perhaps one of these dimension will allow access to a parallel existence along a differing world line. I don't think there is anything in physics that absolutely rules out time travel to the past but there is always that pesky c (speed of light) to contend with. In my opinion, don't hold your breath.

Going back in time=Absolutely impossible.
Going into the future is where it gets a bit more iffy. If you were to travel at close to the speed of light you might be able to go thousands of years into the future in only a few hours/minutes or your time. Of course you would never be able to go back and if you didn't like the future you would be screwed.

You cant travel back in time and deliberatly change something thats a fact, if you did that thing would not have happened in the future therefore giving you no reason to go back in time from the future. You could freeze time relative to the observer though If you could travel at
2*C, you could technically go to the sun and back fast enough to see yourself leaving.

So you can go into the future, you can even freeze time relative to a stationary observer, but you cannot go back in time.

And also you cannot move faster than light that is relative to your position/speed because light will always moves away from or towards the user at 299,792,458 m/s, Dont know if anyone has a clue about what I mean ;D

I think there isnt enought energy to go to the past in a single universe. Maybe you could go to another universe that would reprensent the past, but in fact has the same age of your universe.

Good. Now, how can you freeze time relative to the observer? wouldn't the observer see you move twice as fast*c as it should?

Also: "If you could travel at
2*C, you could technically go to the sun and back fast enough to see yourself leaving."

Hm. That conflicts with my theory of time self-replication. As seen in the butterfly effect, if you played with time, do you think you'd see yourself or you'd be yourself at that time? I'd have to think about this

Theoretically, when you reach the speed of light, length becomes zero and time stands still. In your frame of reference, time seems to be non existant, where as relative to the Earth (everyone else stationary), time goes on as normal.

Dude, don't spam my thread. Only me, VI & official spammers can.

Oh..wait....it IS, i HATE clowns, and a clown being hung is funny to me. But well......my point is: DON'T SPAM MY THREAD, AND IF SUPERMAN WOULD SAVE SOMETHING, IT'D BE HIS GONADS FROM CHUCK NORRIS' RANDOM ROUNDHOUSE MORNING KICKING.

Oh..so YOU see them as stationary. When you're in "a time machine" you see everybody else frozen?

VW · Jun 24, 2008

I don't know. It kind of goes beyond the point at hand, that attaining that speed is impossible... I doubt you would see anything since you're, well, traveling at the speed of light lol...

sorry for ruining your semi-serious thread it's just my nature :-[

It IS serious, the fact that i add jokes around there doesnt make it false or stupid.

diachi · Jun 24, 2008

Technically if you flew into a black hole you could pass into another universe because there would be enough energy stored inside it, because all the light and heat and matter gets sucked in, and stored, and if there was enough energy released it could rip the fabric of space, technically.

Well for the past this is IMPOSSIBLE unless somehow we found out the only way is through a black hole(which i learned from experiene is faster then the speed of light and not even light can escape it!!!!) so in this case light cant escape right so possibly if we could track when and where the black hole opens and get something to go through it we could see if this leads to a new dimension
plus on the side a black hole is very powerful if a human went through there it would probably alter your body by putting on more than 1000 tons of pressure causing you to get smushed more then a pancake rolled over by tires ;D

futuristic time travel is possible if we further more explore cryogenics
if it is possible to freeze yourself without damaging the tissue and keeping your body intact and making you sleep(getting sci-fi)you might be able to wake up 1000 years in the future

EDIT:not from experience sorry guys
