• Time Travel, Possibility or Fiction?

Not to poop the party or anything, but.. 1. Unless accommodations are made for the fact that Earth is turning constantly, there's a high chance you're going to appear somewhere else than where you left from. Like in a nuclear reactor. 2. If you travel back in time far enough, the soil buildup over time will no longer be there. You will appear high in the air. You will die. If you travel forwards too far, you'll be buried underground. 3. A time machine is probably going to be in a secure location. If you go back in time to when the machine wasn't built(unless your machine also accommodates location) you'll be appearing underground.

[QUOTE=Bat-shit;33408400]And 4. It's a concept created by us.[/QUOTE] In that case, so is distance.
[QUOTE=JohnnyMo1;33409607]In that case, so is distance.[/QUOTE] I suppose. But still there are distances between different points, no matter what scale of measurement you use. Inside our planet, meters and kilometers work fine, but go a little further into space and the number of kilometers grow to be non-comprehensible very quickly. Relativity, I guess? As for time-travel.. By all means it seems like a science-fiction gimmick to me. Please enlighten me how time traveling has a place in our universe, and where can this phenomenon be found/observed/mentioned seriously/whatever?

Inb4 you say both time travel and distance are concepts.. not what I mean :v:[/QUOTE] Nope. The distance between two points in space changes depending on the frame of reference from which it is observed and in exactly the same way, the duration between two events in time changes depending on the frame of reference from which they are observed. It DOES matter how you measure it for both, but the change is exactly determined by physical law. Both of these effects are unified within the framework of relativity because space and time are no longer considered separate. They are both a part of a single manifold, spacetime.
Oh didn't see you being in this thread. I was editing and stuff. lol But uhh.. okay, frame of reference.

[QUOTE=SIRIUS;33411551]you're making some extreme assumptions about how time travel works here[/QUOTE] Considering that we've never actually done it, you could say the same about anyone who's ever assumed anything about time travel. Even so, I'm not assuming. I'm stating simple facts. If your time machine does not factor location into the equation, you will have problems. That's all there is to it.

What different kinds of time machines are there? Are you an expert on time machinology? I'll bow to your superior wisdom, just explain to me what kinds of time machines there are.

Wormholes have the minor problem of actually finding, or creating and sustaining, one long enough to use it, and then there's the problem of getting back. High intensity lasers in a spiral is pretty vague. To be honest, I wasn't thinking of the actual science theory on it. I was pointing out practical reasons that, based off of simple physics that anyone should already know about, time travel probably would not work out too well.

I heard the only way it would be possible was with worm holes. Its also highly improbable to figure out where and when a worm whole will occur. So it isn't impossible just highly improbable.
The idea of a wormhole relys on theory that a wormhole is is a natural event. If it were man-made it could lead to anywhere. If one where to know the destination of the other end of said wormhole, that person or persons could get back to the started destination. If a time machine was a stationary type, it would cause problems such as ending up in large amounts of earth. Thats why if a machine was made it would have to be made just outside of our atmosphere, calculated to end up in a spacial location that has no matter in it at the time of arrival. Otherwise you'd end up in a satellite or the core of the earth or something.
Quantum foam says that there are billions of wormholes everywhere forming billions of times every billionth of a second or so... just find one you like then somehow... expand it
Isn't quantum foam theory? If "billions of wormholes everywhere forming billions of times every billionth of a second or so" wouldn't we have seen at least [i]one[/i] by now? It makes little sense to me if any.

[QUOTE=Rocko's;32720804]Time Travel, Oh boy does this topic cause debates, it's hard to know if us humans will ever be able to actually travel in time. For me, after watching BTTF, I was puzzled with questions about time travel. Before we head into a debate, lets read the wiki, [url]http://en.wikipedia.org/wiki/Time_travel[/url] I believe Time Travel is a possibility, but there can be a chance that we will never find out. Or for my life span that is, maybe in the future, but right now its a topic that's still being discovered and debated.[/QUOTE] Wikipedia is an invalid source
[QUOTE=Grant Gibson;33424402]Wikipedia is an invalid source[/QUOTE] disagree
[QUOTE=SIRIUS;33424385]they are very very small, no you do not see them[/QUOTE] That makes a bit more sense, I'll have to look into it.
On the premise that Time is a human idea: Time is movement, and movement is a reflection that "time" has passed. If the entire universe was at absolute zero and no movement ever took place, time would not exist. Time, however, is certainly not a human construct. If you can observe and measure movement, you can observe and measure time, and that makes it as much of a human construct as everything else in the universe. But how does this relate to time travel? Well, the idea that this premise poses, is that if we can reverse the expansion of the universe itself and the movement of all the particles in it, then we have traveled back in time.
[QUOTE=Grant Gibson;33424402]Wikipedia is an invalid source[/QUOTE] You do realize that that page has a lot of sources, right? It would be invalid if it didn't have any sources at all or if the sources were crap. [editline]25th November 2011[/editline] [QUOTE=SIRIUS;33424385]they are very very small, no you do not see them[/QUOTE] Small as in human size or smaller? Still, there's no documented sight of them, so it's all based on theories, right?
In my opinion, there is no way to go into the future, or into the past. Time however is not a fixed constant, and can be manipulated. [URL="http://en.wikipedia.org/wiki/Time_dilation"]http://en.wikipedia.org/wiki/Time_dilation[/URL] When two observers are in relative uniform motion and uninfluenced by any gravitational mass, the point of view of each will be that the other's (moving) clock is ticking at a slower rate than the local clock. In other words, if I take off in a space shuttle going 95% the speed of light, for me 20 years may go by, but for the stationary person on earth, 30 years may have gone by. Therefore, I "slowed" my clock by 10 years, and can be thought of as "going into the future", but in reality, all you did was slow time for yourself. ***No math was involved with that, the theory is correct, but I did not use any formulas. This was also proven, from sending atomic clocks orbiting around Earth. This means that two clocks that had exactly the same time on them, to some crazy decimal place, like 30 or something, were created. One left on Earth, and thought as "stationary" and on was sent to orbit Earth. When the orbiting clock was retrieved, it had less time on it then the stationary clock.

FACEPUNCH, I am from the future. I came here from the year 2036 to warn's you ALL. a NUCLEAR war is upon us. ALL non christians will be punished as a result (we ruled out it was there fault). I am spreading christian teachings all over the net to SAVE you ALL. this is nothing to joke about transmersion OUT
Anything is possible. Practical? Different debate entirely. Is it a good idea? FUCK NO its not a good idea. Too many variables and far too much power for any individual or group of individuals, but again... different debate entirely.
How can you go back in time to like the prehistoric times if your aren't even born yet, wouldn't your age also go back in time?
