[QUOTE=JohnnyMo1;34470744] [QUOTE=King of Limbs;34469673]Time is a measurement. So no.[/QUOTE] Wat [editline]30th January 2012[/editline] So, because distance is a measurement, I am incapable of moving backward[/QUOTE] What he was trying to say is that, in a nutshell, time is not a physical thing, but a representation of changes in a physical system (thermodynamics basically). Time travel relies upon the concept that time is a tangible thing, and that the past is a place (not a memory or record), as is the future. From a basic viewpoint time travel is obviously not possible, however when you get into special relativity and other areas of physics, theoretically it could be. It's all very confusing stuff. [QUOTE=userman122;34498109]There is no doubt that time travel is possible. We do it all the time. EDIT: Look: Just traveled 4 seconds in time.[/QUOTE] [img]http://farm5.staticflickr.com/4119/4876696414_d3f62d18be_m.jpg[/img] [highlight](User was banned for this post ("Image macro" - JohnnyMo1))[/highlight]
The time is different for all of us. No doubt. Its just so small differences we cant notice.
[QUOTE=GetOutOfBox;34522533]What he was trying to say is that, in a nutshell, time is not a physical thing, but a representation of changes in a physical system (thermodynamics basically).[/QUOTE] Time is just as "physical" as space is. In matters like this it's best to just forget everything you know by intuition and view time as another dimension.
[QUOTE=Rad McCool;34528975]Time is just as "physical" as space is. In matters like this it's best to just forget everything you know by intuition and view time as another dimension.[/QUOTE] Agree.
[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] By Wiki's definition, no its not possible, but by my definition it is in ONE direction, not both. It is possible to go forward in time, which was proven by Einstein. By putting an atomic clock in a satellite, which was matched up with another one of his atomic clocks, moving at high speeds around the Earth, when the clock was retrieved, it was several seconds slower than the one on Earth. This showed that the clock in the satellite aged slower than the one on Earth, proving his thoery that, at speeds close to the speed of light, hundreds of years will go by feeling like seconds to the traveler. You also shrink alot when you go that fast. So traveling into the future? Possible! Traveling to the past? ... Not so much :(

I want to believe it is, but at least at the moment, I think it's still science [B]fiction[/B].
[QUOTE=CorporalCupCake;34551415]I want to believe it is, but at least at the moment, I think it's still science [B]fiction[/B].[/QUOTE] Assuming we can go faster than light (which is only impossible because of our current understanding of acceleration), it's quite factual when looking at modern physics (which look to be very correct).
[QUOTE=Rad McCool;34498190]4 seconds in relation to what?[/QUOTE] Four seconds related to ABOUT the rate at which our heart beats. If I understand how time works right, those same 4 seconds passed everywhere in Space at the same time just elsewhere, here, everywhere! BUT just 4 seconds is a tiny fraction of a considerable fraction of the time that has passed so far to this second.
What is your point?
[QUOTE=Gekkosan;34573066]If I understand how time works right, those same 4 seconds passed everywhere in Space at the same time just elsewhere, here, everywhere! [/QUOTE] You don't understand how time works.
It occurs to me, if I ever did make a perfect time machine, I'd go into the past and give it to myself. Thus eliminating the need for me to invent it in the first place. I guess we'll just wait and see...

[QUOTE=JohnnyMo1;34576154]There is no absolute notion of the rate at which time passes. It depends on your reference frame. [url]http://en.wikipedia.org/wiki/Introduction_to_special_relativity[/url][/QUOTE] Oh I see what you mean.. That's funny as hell! We couldn't possibly tell the rate at which time passes, but yet it is passing all the time, even second by second if you want to see it that way. Or hour by hour, or billion years by billion years. So.. what I can tell is that time moves slow, or that there is just simply so much time we could rebuild our civilization like ten times over and over again. Mind-boggling.
[QUOTE=Gekkosan;34587206]That's funny as hell! We couldn't possibly tell the rate at which time passes,[/QUOTE] Sure we can. Use a clock.

I say it is not possible but you are able to travel to alternate dimension where it is a replica of what it was like in the past of your current dimension.
[QUOTE=JohnnyMo1;34588992]Sure we can. Use a clock.[/QUOTE] "There is no absolute notion of the rate at which time passes." but alright
[QUOTE=Gekkosan;34594710]"There is no absolute notion of the rate at which time passes." but alright[/QUOTE] Right, but there is still a relative notion. You can measure how much time elapses between two frames of reference.
It's such a stupid concept. Time is an intangible manmade form of measurement. You have a better chance building a machine that teleports you to Valhalla.
[QUOTE=Ryan Reefer;34614755]It's such a stupid concept. Time is an intangible manmade form of measurement. You have a better chance building a machine that teleports you to Valhalla.[/QUOTE] time is a measurement, like distance you can move along it either way. saying time is a man made thing is like saying distance is man made. the unit of measure is but not the measure itself and saying its stupid is blatantly ignoring the FACT that travelling in time (forwards at least) is possible
Don't fuck with the fabric of the universe, it would be quite unlikely that we would be able to time travel , let alone use some kind of teleportation device with any [U]success[/U]. [editline]9th February 2012[/editline] Valhalla is another name for heaven. Heaven does not exist, so Valhalla does not exist too.

Well, we once said it was impossible to fly, and we ended up on the moon. But time travel has a few faces. Such as physically going from point C to point A or vise versa. OR that sci-fi Time Manipulation centered plot device that makes FTL possible. Soooo honestly, given enough time I'm positive some sort of time travel be it "Skip-go" into the future or a ride back into the past. The thing i really wonder is why? If we could "Look" into the past without actually physically being there wouldn't that be enough? Going back in time has the potential to do extreme damage. Putting all the paradox's and ripping the fabric of reality aside for a moment. If a person could go back in time and try to prevent a mistake. Then that person would never take responsibility for his or her actions, and basically never learn from mistakes. And i wouldn't want to even start to begin now bad things could get if people fell into this mindset. Now if we created some sort of time-machine that would allow us to fly around space safely and at stupidly-ridiculous speeds, which i have my doubts is even possible... then cant see it being to bad.
I've watched many shows on this, and they've all convinced me its possible. We cannot travel back, but we can travel forwards. See, according to what some scientists say; you cannot travel back past the date the Time Machine was created because it did not exist. There are many theoretical ways to travel in time though. Just going into space is one. Another is going around a black hole, worm holes is another. Then there's traveling at the speed of light. Main problem with those is theres no turning back, but I guess its a down-side one could get over with flying cars on Mars.

Example: Guy A and Guy B are friends, Guy A goes back in time and kills Hitler himself, Guy A disrupts his timeline and changes it for him. However, Guy B did not go with him, Guy B will live in his own time without Guy A. Time travel is a strange concept, what if Guy A comes back, does Guy B in his timeline meet him, or is Guy B never gonna see Guy A in his timeline again?
I thought it was fairly common knowledge that a sense of accelerated "time travel" is possible through relativistic effects. [URL="http://www4.ncsu.edu/%7Ecarroll/time_travel/forward.html"]http://www4.ncsu.edu/~carroll/time_travel/forward.html[/URL] When we have the ability to do so is obviously a completely different story. I'm happy to believe travelling to the "past" is a bit of a null concept though, I think there's a good reason it brings up so many paradoxes - we're trying to translate [I]our[/I] interpretation of time onto the physical world - it's the limiting nature of our consciousness that leads us to think of existence in terms of past, present and future and trying to apply these limited ideas outside of our own minds will unsurprisingly cause mind fucks. /opinion
