• Time Travel, Possibility or Fiction?

It's science-fiction to start with so yes it's an impossibility.
Everything is possible, given enough time. We can't think that advanced right now. Were basically too young of a species to do it, even wrap our mind around it.

[QUOTE=Gekkosan;34276427]It's science-fiction to start with so yes it's an impossibility.[/QUOTE] Science-fiction =/= impossibility There is science fiction, which is "implausible (unlikely) made possible" and then there is science fantasy, which is "impossible made possible" Many are philosophical Science fiction- Brave New World, Island, Mote in God's Eye Science fantasy- The Time Machine, Stranger from a Strange Land Many are for entertainment Science fiction- Science fantasy- Star Wars And some science fiction novels look at what kind of amazing things could be found/built in space, like Niven's Ringworld. On topic: Time transcends our naked perspective; we can not grasp it on our own, therefore it is unlikely that any time soon we will have a positive answer to this- this is a fairly empty debate.

[QUOTE=JohnnyMo1;34276677]Fantastic argument [editline]18th January 2012[/editline] "it seems like it shouldn't be possible therefore it's impossible"[/QUOTE] Well, how would you go about time traveling? Obviously we can't yet, but what would be the best approach to doing that? Just speculate. I wouldn't know. And by saying it's science-fiction and thus far from being a possibility, I mean that for example the film "Back to the Future" is probably one of the few things that you can even think of when talking about time traveling. Then there are some very interesting theories like curving the quantum field of Space or whatever it's called, like taking a shortcut through a wormhole or something. Sounds far-fetched too, but if not that then we need more speed. A lot more speed.

[editline]19th January 2012[/editline] [QUOTE=JohnnyMo1;34291300][url]http://en.wikipedia.org/wiki/G%C3%B6del_metric[/url][/QUOTE] Had a look there, and I've surfed some of that shit before.. It's pretty high-end mathematical physics so welp. If you'd care to elaborate how we could go about time travel in practice? The closed timelike curves and stuff doesn't really ring any bell inside my head, or how you'd apply them in a time traveling machine? But I guess the time will tell.
It's not really important if it's feasible in practice. The Godel metric shows that it is allowable by the laws of physics, so it is certainly possible.
Cryogenics seem to be the only reasonable "time travel" to me. The future doesn't exist yet, and the past doesn't exist anymore. But then again, time may work differently, it may not exist at all. Mayve every fraction of a moment, every quantum event, is a whole seperate dimension.

Would I be stupid to think that a device that can plant you in a timeline while everything else moves forward would theoretically allow you to "Pause" time of sorts? Think of a butterfly net, you get caught in the net while the top part of the net keeps growing upward. Of course everything always sounds better in my head so this might be stupid, but am I wrong?

[QUOTE=Motie;34301275]Why would going faster than light make you go back in time?[/QUOTE] i think it's the same principle that makes time slow down for those going near the speed of light
I personally do not think time travel is possible. At least, not back in time. Because that would mean the future is already happening in millions of ways and every second would be another dimension... This is way over my head.
I like to think of the theory of a time machine similar to that of a video camera. when you turn the video camera on, you can record everything from that point on. And when you watch the past events on the camera, it will not show anything from before the time that it was turned on. With the video camera representing the time machine, this is the reason why we haven't seen anyone from the future, because they cant travel back further than the point of the creation of the machine.
Time is a measurement. So no.

There is no doubt that time travel is possible. We do it all the time. EDIT: Look: Just traveled 4 seconds in time.
4 seconds in relation to what?
[QUOTE=Rad McCool;34498190]4 seconds in relation to what?[/QUOTE] The time that just passed by. Without moving in time nothing would happen. There is no reason that we cant move faster or slower in time, is it? Why should there be a defined time-moving speed that is static?

The time that just passed by was 4 seconds. In relation to that time you haven't traveled anywhere.
We are time traveling forward as we speak right now. Due to general relativity we can experience time slower relative to an outside body if we are moving faster (If you are walking you experience time slower, but on a negligible scale). If you were to crank your walking close and closer to c (in which c is the speed of light) you would experience time slower and slower. So to time travel forward (on a quantum scale you are working slower and your surroundings are working faster) you would have to be moving -> c.

That can be handled by special relativity. To go backwards, however, you need general.
