The concept of time travel

Ok, let's start here.

That original comment was obviously directed towards me. Anyone with eyes and a basic understanding of the English major could see that. And I did not give you those -rep points. You don't -rep someone when they disagree with you. That is not how the system works, and I refuse to use it that way. And it's people like you, who attack random people unprovoked around here that Nikon warns about. And, as I have been informed by friends, if you think I am childish enough to attempt to get you banned for this confrontation, you are sadly mistaken. The report function is for users who are abusing the rules and regulations in a big way, not what you are doing. I am not going to tolerate your snide remarks about the good users of the site, and I am not going to sit back and watch as you try to talk your way into a coma. Honestly, as an American citizen, I believe you have the right to voice your opinion. Besides, someone has to be wrong, right?

This shit is bananas, i think if it actually comes down to 'taking sides' im making my own side.

As a completely neutral bystander, all I have to say is:



is, well, an epic fail, in the light that:




and:



Anyway, time travel by going faster than light can't be done. As an object approaches c, mass increases to the point that at c mass is infinite... so unless there's a value greater than infinite (not to mention building a machine that can handle having more than infinite mass), or it has no mass in the first place, travelling backward in time by travelling faster than light just isn't possible.

If you feel the need to argue, don't hijack someone else's thread to do it.

Thanks :D

*salutes*

well, if somebody time travels back to the past, would that past would be the same past everything in the universe went through?

well, i like the idea of alternate worlds too

So do I. Hell, if I ever mysteriously go absent, you'll know that I found a portal in the middle of the street and thought "Fuck you guys, I'm getting married."

See? That's the reason that I love Multiverse theory so much. it just makes me warm and happy knowing that somewhere, sometime, somespace I'm shooting down those dirt Gelchorians in a giant steampowered robot, meanwhile in another universe or dimension, everything in exactly the same save the fact that I did not make this post on the forum.

Infinite possibilities are awesome.

i've just thought of something interesting thanks to stephen king. actually, it's his idea and i'm just jacking it but has anyone read four past midnight? in it, there's a story called the langoliers and to make a moderately long story short, a plane goes back through time due to a rift and then forward through time through the same rift. if anyone wants to read it, the rest is one giant spoiler so, for your own curiousity's sake, don't read any more.

what's interesting, though, is that in the story when they went back through time, it wasn't necessarily the past. it was what was left over of the present so everything was dimmer, staler, and felt used. for example, soda and beer were fizz-less, food had no taste, matches wouldn't burn, cigarettes tasted bad, etc. the scary thing, though, was that eventually these things called langoliers appeared and they ate the remaining vistages of the past erasing everything and causing nothing.

the future was different too. it wasn't what was gonna happen but it was, more or less, just an empty setting waiting for the present to catch up to it.

the whole story was a good read and i just thought if multiple universes are a theory, why can't this? it's an interesting concept, nothing says the past has to remain or that the future's already written. it kinda scares the shit outta me, though.

that sounds like something Nasu's (go play TsukiHime and it'll have stuff about vampires and like aging=time: like how Ciel is "stuck" in "time")

so like time influences existence in Nasu's world
instead of something that sounds like "space-time" where the universe is 4-dimensional


as for me, if i have to include "existence" as a dimension, then the universe is like 5-dimensional

i mean like the existence of alternate or parallel worlds

there is a possible way to travel forward in time. i dont know much about it but Einsteins theory of relativity "time dilation" is the phenomenon whereby an observer finds that another's clock which is physically identical to their own is ticking at a slower rate as measured by their own clock. This is often taken to mean that time has "slowed down" for the other clock, but that is only true in the context of the observer's frame of reference. Locally (i.e., from the perspective of any observer within the same frame of reference, without reference to another frame of reference), time always passes at the same rate. The time dilation phenomenon applies to any process that manifests change over time." this was from wikipedia i dont know this, haha but to take it into context, if I were to travel into space (we will say 1 million light years away) and it took me 10 years to do that, the theory says that i would have only aged 10 years, but the people on earth would have aged 100 years. I think thats how some part of that theory works. so in a sense you traveled into the future. if you know more about this or i am wrong feel free to correct me. but if this is true i would go into space and check out whats out there and them come back to earth 100 years into the future. in a sense though its still the present to you. pretty crazy

Heres my hypothesis. If space truly is infinite then somewhere in there the infinite amount of event there is a world identical to one we live in just maybe a little back in time or a little further in time. So this prevents the thought of a time travel machine being invented and at the moment it is operational the changes that occur from it that have been used to alter the past would be seen at that moment. So instead you just leave your own "time" of the world you're in. to go join the "time" of a world completely identical to you're own while they are in a "different" time. Now the possibility is there but the chance is close to impossible since the distance i would imagine for these separate "times" must be incredibly far away from each other. But then if space is truly infinite then there may be a scenario where the two "times" are close and far of infinite distances to each other.

like time has slowed down for the object that moved faster than another

You might think that you travelled forward in time, and yes, in a sense you have, if you compared the relative time passed from both frames of reference. However, don't forget that you have to travel back. So in a sense, when you go back, it's analogous to the Earth traveling towards you; basically, Earth's frame of reference traveled forward in time to your frame of reference relative to an outside observer. So technically, you haven't traveled into the future at all, since by the time you get back, you're in the same frame of reference as the Earth. Even if you decided to send some sort of message back while you're out there, while the message travels back to Earth relativity will make it so that it reaches the Earth exactly 10 years after you left. In other words, even if you did travel forward in time, you wouldn't know because you need someone from another frame of reference to tell you you did, but when the message gets there, the effects of relativity are nullified when it reaches your frame of reference.

Hope that made sense; it requires understanding of what a 'frame of reference' is.

The problem with that is that ever since the big bang theory, very few people believe that space is infinite.

or warped/looping?

the big bang theory does have its points but to me its not acceptable enough that a society that a species generated such as ourselves could exist within a set parameter of possibilities.
