That's not FTL travel. [editline]10th January 2012[/editline] It's rather the same principle as claiming you're faster than Usain Bolt because you took a shortcut on the 100m dash.
If time goes slower in a strong gravitational field, does that mean that if an anti-gravitational field could be created, time would move faster within it?

[QUOTE=wizard`;34140442]what about something with negative mass?[/QUOTE] Not even that could go faster than light. In order to travel faster than light, an object would have to have imaginary mass. [editline]10th January 2012[/editline] [QUOTE=cartman300;34140621]What if Einstein was wrong?[/QUOTE] I don't think you quite understand how science works. Einstein didn't just go "hey guys what if nothing can travel faster than light" and everyone went "this guy's pretty smart he's probably right." There is a huge body of experimental evidence for the theory of relativity.
-.- What if the experiment did go wrong?
It's not "an" experiment, it's dozens of completely different experiments performed by different groups of people all over the world through the years. And the results are peer reviewed by other scientists before they can be published. The whole idea of science is building knowledge through repeatable experiments, not just some guy does it somewhere and tells everyone else he did. [editline]10th January 2012[/editline] Hell, even most single experiments involve several runs. Not just a single measurement.
I give up
fiction, IMO, and based on what I've seen from people in the thread [editline]10th January 2012[/editline] [QUOTE=theevilldeadII;32722295]I thought that was Fiction[/QUOTE] Cryogenics is a real practice, however it is mostly used by people with more money than sense, and sold by money grabbing bastards who know the fundamentals of it are seriously flawed
[QUOTE=cartman300;34138899]Time travel in the past is possible... If a object is moving near the speed of light, it would be less affected by time as the world around him. If a object moves the exact speed of light the world around him would be paused, stopped... If a object is moving faster than light the object would time travel backwards in time... If you travel back in time a new universe is created and if you kill your parents nothing will happen. It's because a new universe is created in multiverse.... Time travel solved. BTW. Faster-than-light travel is possible... EDIT: And no time traveler has traveled back in our time because what is the propabillity for 1 - 100 humans to show them in EXACTLY this universe in the multiverse?[/QUOTE] The problem with moving faster than the speed of light is that even if we humans were trying to accelerate a rocket to the speed of light, for example, as the velocity of the rocket approaches the speed of light the energy needed to actually make the rocket travel at the speed of light is infinite. It would take more energy than is currently contained in the universe to move matter at the speed of light, making it practically impossible to do so.

[QUOTE=cartman300;34141313]The question was if time travel is possible not how much energy do we need xD[/QUOTE] And he just answered that question saying it isn't, by explaining you'd need infinite energy to support such a thing, which just can't be done.

Could going through a wormhole put you in the past? Or can it only take you to the future?
[media]http://www.youtube.com/watch?v=vY_Ry8J_jdw[/media] Sorry, I had to. But on a more realistic note, time-travel to the past doesn't seem very likely. If it was, we'd notice it. People coming to our time dressed oddly, or acting differently, talking differently and LOOKING different. Not to mention someone would eventually try to kill a mass murderer or two and our views of hitler/stalin/any other dictator would change at the snap of our fingers. Unless they are, like explained in Doctor Who, fixed points in time that cannot be changed.
[QUOTE=Derp Y. Mail;34142993]different. Not to mention someone would eventually try to kill a mass murderer or two and our views of hitler/stalin/any other dictator would change at the snap of our fingers. [/QUOTE] but what if that created a different "world/time line" where Hitler/Stalin Died? Kinda like a parallel world/universe where the things that happened in this world, didn't happen in that world.
[QUOTE=booster;34143040]but what if that created a different "world/time line" where Hitler/Stalin Died? Kinda like a parallel world/universe where the things that happened in this world, didn't happen in that world.[/QUOTE] Which makes me reference Doctor Who again, because the Doctor mentions something about multiple universes being stacked on and next to eachother where new decisions are made and they're not and a whole bunch of factors create new ones and doesn't.
maybe this question is outside the known box. maybe we have to think about it outside the whole universe time thing. For Me it is possible... But it is Nearly impossible. Or Baybe there is already a way, but we don't know who can and how :D ergo: time is relative and this question too.
[QUOTE=booster;34142916]Could going through a wormhole put you in the past? Or can it only take you to the future?[/QUOTE] it would probably kill you
[QUOTE=cartman300;34141622]If i had so much energy it would be possible, witch does not mean it is impossible. Only energy.. lol[/QUOTE] Um, no. Requiring infinite energy means it is fundamentally impossible.

What about this though? [QUOTE=Nikita;34140374]If time goes slower in a strong gravitational field, does that mean that if an anti-gravitational field could be created, time would move faster within it?[/QUOTE]
[QUOTE=Nikita;34147428]What about this though?[/QUOTE] I am not sure if, lets say, general relativity allows anti-gravity. Personally I think that timetravel is possible, yet you will be moving in another dimension so that you would not indirectly affect your own life. Say I traveled back to 1940, when my mom was born and killed her. I would not die, because I did not kill my "real" mom. This requires more dimensions though. Maybe the string-theory is correct?
Sure, I think it's possible. I might seem like a lightweight in this thread, but sometimes I like to think about it for the lulz. You look at the clock and memorize the time and place and just start thinking about travelling back to the before-mentioned time as soon as it becomes possible...while thinking about this, your "future self" pops in for a visit.

And then I think a couple years back when I thought that, and realize I'm glad future-me didn't come back then, for various reasons.
[QUOTE=theevilldeadII;32722295]I thought that was Fiction[/QUOTE] No bro, they froze Walt Disney and are keeping him in the Disney Vault. [editline]11th January 2012[/editline] I think cryogenics is a good idea, however, freezing yourself for a couple hundred years or decades just doesn't seem beneficial. Why live half of your life today and freeze yourself only to wake up in a world unknown to finish out your days. Seems sad and lonely if you ask me. You should all watch Vanilla Sky (2001) if you're interested with the idea.
I think it is possible to go back in time, but going back in time is probably going into a Paraell universe, which means you wont change the future. [QUOTE=Elexar;34143995]it would probably kill you[/QUOTE] Agreed, even with a shielded space ship your probably going to end up being "Spam in a Can" when you enter a Wormhole. A useless theory that is completely unrelated to the thread: Black Holes are probably sending whatever is sucked into them out of separate "White Holes" so it acts like a teleport.
