[QUOTE=The Pwnapple;29393489]Time travel isn't real.[/QUOTE]
relatively, or absolutely?
if you say that as a relative statement, then yes, time travel is real.
but if you say that as an absolute statement, then it depends.
So many possibilities would be had if time travel was possible.
But, no one would ever know that the past was changed, as it would simply become fact in the future, rather then a change. Mindfuck to think about.
[QUOTE=Master117;29393098]It's funny how you mention this. This is exactly how light travels through our universe. I read a scientific article that stated something along the lines that light itself is stationary relative to itself. It's the universe around it that's moving. In other words, if this is true, then it's not constrained to our fabric of space like everything else is. If anyone can find the article, that would be fantastic.
This is essentially the ticket to essentially teleportation if done right. [b]Move the universe around you, and not moving within the universe[/b]. .[/QUOTE]

Where are the people from the future where this stuff has been invented?
Insert all manner of special pleading in your reply.
Unless the people from the future... Go int oa different timeline.?
Like how if you do something in the past. you are changing another branch of the time line or something

Naw just kidding. But why would time travel backwards when you are going faster than light? I know quantum physics is a clusterfuck of "lol wth am i doing", but it seems like that theory was just pulled out of someone's ass. Care to elaborate on that theory?
[highlight](User was banned for this post ("Image Macro" - Craptasket))[/highlight][/QUOTE]
Mind if I ask why this guy was banned for this post? I know most image macros are just fucking stupid and shouldn't be posted, but I (and seven other people) thought this one was funny. Even if you didn't think it was funny, there was a legitimate response right after.
And back on topic: My question is basically the same as Chernzobog's. Why the hell do you go backwards when you go faster than light? How do we even [i]know[/i] light is the fastest particle? Maybe it's just the fastest we've seen so far. There's more to it i'm sure, but it's probably some super-complicated shit I won't understand.
I remember reading/watching (can't remember) an article/video about how time-travelling actual matter would be theoretically impossible, but say building a machine meant to send pulses of light in morse-code/what-have-you back in time would be theoretically possible.
So as to why people haven't come back and told us shit yet is because they can't, and won't be able to send messages back until we actually build the machine capable of doing it.

As far as I understand you'd only go back in time relatively, so you could travel faster than light then stop and the light from events which happened much earlier absolutely would only just reach you, essentially you are seeing the past. I'm not sure how you can actually go back in time absolutely through speed alone, explanation anyone?

Which will be impossible until we see the machine they've built.

You've seen this thread before? Hot damn! proof!
what the fuck.
I always find myself thinking about time travel, and always end up going to far into it and getting confused about paradoxes and stuff like that.
[QUOTE=Dark-Energy;29392942]Well, you could always invent a warp drive, and travel faster than light, while not technically traveling faster than it at all.
Though I wonder how that would work actually, because warp drives are scientifically possible, we just need enough energy to do it, which we don't have yet. I'm pretty sure since space moves instead of you, that time would not dilate. So I assume warp drives could not be used for time travel, only for large distance traveling.[/QUOTE]
Warp drives require an as yet unknown exotic matter with negative energy.
Yeah it doesn't exist.

Time travel is impossible simply because there is not a past or present to travel to.
[QUOTE=JgcxCub;29394576]Why is time considered a dimension?[/QUOTE]
To describe an event it's insufficient to only list its spatial coordinates. You need a temporal dimension.
[editline]24th April 2011[/editline]
if you have a date with a girl, it's not irrelevant when you arrive, right?
Future time travel is definitely possible; fly to Australia and when you land you'll have gone a million-billionth of a second (or something) into the future.
Time travelling doesn't sound necessary.
Or even relevant. Time is money, so we gotta spend it efficiently, and we got a whole lot of it.
[QUOTE=Ac!dL3ak;29393362]then please solve the grandfather paradox for me.[/QUOTE]
What would happen if you traveled back in time and killed your own parents?
There are three ways this can be solved:
[list][*]Different timelines. Like Back To The Future, all possible outcomes of reactions exist in infinitely many worlds. And when you travel in time, you also travel between these worlds.
[*]It's impossible. You simply cannot kill your parents. Some force will prevent you from doing it.
[*]It's meant to happen. Your destiny was to travel back in time and kill your parents. This is the opposite from the above, since there was no way you could've prevented it from happen.[/list]
Of course what truly would happen out of these three, or if something else would happen, remains purely speculative.

[QUOTE=flyschy;29392732]
Something of interest with the time space continuum is that it is hugely affected by large objects. A planet or star resting on it actually has the effect of causing a dent in space-time like this.
[img_thumb]http://i52.tinypic.com/27zaws6.png[/img_thumb]
(Also of note is that this effect is what causes gravitational attraction between masses).
[/QUOTE]
Isn't this very much debatable?
Not really, realtivity is one of the best theories we currently have to explain the universe. It explains why we have gravitational lensing and why gravity acts instantly.

What if the nature of time depended on the nature of space? What if in the unstrained areas of the universe, time is more rigid and hard to change, with destiny and fatalism running rife, but in places stretched thin like a mother of 5's area (excuse the vulgar analogy), time can be moulded like soft wet clay, and things can be "rewritten".
And on the subject of history changing, like killing your progenitors, perhaps there could be some sort of "immune system" of time, some force that minimalises the effects of paradoxes and time loops. And if such a thing didn't exist, remember the words of Voltaire, "[I]Si Dieu n'existait pas, il faudrait l'inventer[/I]" ("If God did not exist, it would be necessary to invent him"). Now, replace "God" with a different thing, like a temporal immune system. If there weren't a temporal immune system, it would be necessary to create one, like founding a "Time Agency" to regulate time travel and ensure history turns out right.
And another thing; in the theories of spacetime, space and time are intertwined, right? Well, is there anything to prevent the possibility of variances between space's strength and time's strength? And by that, I suggest the possibility of there being more space than time in some areas, and vice versa.
I can't help but think Method 5: [b]Time Vortex[/b]
