The Five Biggest Contradictions in Fitness

Itís no secret that when people contradict themselves, it has the effect of making the flaws in their actions or statements seem glaringly obvious. But what about when WE ourselves get caught contradicting ourselves by someone else?

    Time Travel

    Alright my friends and I were discussing the possiblity of time travel and what the implications would be. I have some questions for those who are interested in the science and philosophy of it. I always find discussions on Time travel, paradoxes, multi-dimensions extremely fascinating.

    1. Is it realisticaly possible for humans to travel in time? Would we be able to survive the travel?

    2. Does Time actualy exist, or is it something that humans created for themselves? Some say there is no past or future only now so there is no time to travel.

    3. If we could travel in time would it be in the same Time plane, or a seperate Plane? Would be able to say go back and kill hitler and change the present, or would it only change the future of that existing time plane. If say we were to kill go back and Kill our mother would we instantly disappear? What would happen if you met yourself in the future or past, would you really disrupt Time( like back to the future).

    Arrgh!!

    Time travel discussions make my head hurt,time travel is one big contradiction.

    Personally IMO I think that it's like the cloning issue,there are some things we shouldn't be able to do.

    I think this analogy should work."Time is like a river,it goes in many different directions.And interupting time is like ripples in a pond.These ripples could have unseen consequences both good and bad"

    Watch the Back to the Future trilogy,that is a perfect example of what happens when you fool around with time too much

    You cannot turn back time, If you drive your car in reverse will you go back in time nada, if you reverse trough a black whole, do you go back in time, nada.

    If we chould turn the earth the other way.....




    But uhh...doing something like killing Hitler or something enormous like that? That...thats a pretty ****in big change, dont you think? What if the French went back in time (like we'd let them) and aided the British to win the American revolution?

    Or what if the Germans went back in time and killed Lincoln, or FDR, or Patton? Montgomery?


    WHAT IF THEY KILLED JACK DANIELS???

    If you went back in time and changed something (eg killed hitler), then hitler would already be dead when you went back in time, so you wouldn't go back to kill him. You can't change the future because its already happened, so if you go back in time and change it, you still haven't changed anything, because the change you made has already happened, so you haven't changed anything.


    lol, that last part was hard to phrase.

    Depends on how you define "realistic," I guess. There are theories out there that are consistent with current knowledge of physics, yes, but practical implementation is *far* from reality. Most of these ideas revolve around cosmic strings and black holes, or similar massive distortions of space-time.

    2. Does Time actualy exist, or is it something that humans created for themselves? Some say there is no past or future only now so there is no time to travel.

    Again, that's a highly volatile question. The laws of physics are generally time-independent; that is, they work whether time is moving "forwards" or "backwards." There is a slight exception, however-- backwards-time matter would have the opposite spin, making it anti-matter.

    Additionally, there is the measure of entropy which is also a time-dependent quantity. Entropy always increases in a closed system (whether the universe is a closed system is a different matter, however).

    Those two facts lend credence to the idea that time is a "real" event.

    3. If we could travel in time would it be in the same Time plane, or a seperate Plane? Would be able to say go back and kill hitler and change the present, or would it only change the future of that existing time plane. If say we were to kill go back and Kill our mother would we instantly disappear? What would happen if you met yourself in the future or past, would you really disrupt Time( like back to the future).

    This is where it does get tricky. Two main schools of thought here: one, there is no way to time travel, or if there is, the past is self-consistent. In other words, if you travel to the past, then things happened how they did *because* you were there. This brings up issues of free-will and so forth.

    The other idea is that the entire universe, much like a single particle, has a wave-function that expresses "reality." If you travel to the past and change something, the most-probable universe changes. So when you return to the future, you return to a different future than the one you left.

    However, that would make things kinda suck for the time traveler, since by default even his/her presence would change the past. He/she would likely never return to the original universe.

    Millennium was a good flick on time travel. Whenever someone did something that changed the future, the foreign world comes one step closer to destruction. It had a non-stellar cast- Cheryl Ladd and Kris Kristofferson.

    I was discussing stuff like this with a friend and we came on to talking about stuff like teleporting. There are issues with all this stuff. For example, you walk into a teleporter, all the atoms in your body are scanned, and the info is sent to the other teleporter, where you get constructed. Now you've got two copies of yourself on either side of the teleporter, each claiming they have a right to life because they are identical. The copy will be happy because they actually went where they wanted to go, the original was just a tool to get there, so its really unfair if you let them live... This means you have to somehow kill the original, in a completely painless and unnoticable way. This means that everytime you go into a teleporter you die, and some other guy walks out the other end.
    Pretty bent, huh?

    Too bad that can't actually happen because there's no way to scan an atom to that level of detail.

    The theory of quantum mechanics is incomplete anyhow, so we don't know whether the universe is indeterministic or deterministic...

    I'm with the school of thought that, if you went back and time and changed anything the future would be completely different. Therefore, the thing that you went back to change, would no longer have existed in the future that you went back in. So, you wouldn't have gone back. So you wouldn't have changed anything, so the future would be exactly like it was before.

    Oh, and I believe that time doesn't exist. Just like germs and gravity. Just enough people believe in it to make it real.

    Satellites actually have time shifts frome earth, due to there accelation. Its measureable but not noticible. I think also jets flying over the sound barreir too. But Einstein said that travel at the speed of light is impossible since the mass would have to go zero. Did the proofs in Quantam physic but don't rember them. Is there a parrell universe for the satellite that losses time, I doubt it.
    The rest of this thread sound like a you been watching to much star trek.

    I must be bored. But as far the whole hitler thing, if you kill him how do you know that one of the jews he killed wouldn't have been worse then him? Or there offspring.

    Berserker, I think you're talking about how the closer you are to the speed of light, the faster time passes. That parts actually been proven, set two atomic clocks (v accurate) at the same time, then send one off to china and back again on a plane, and have one sat in your office. The one that took the plane journey will be ahead of the other.
    Strange huh?
    I'm not in a thinking mood at the moment so I can't be bothered applying that to what we're talking about...

    Seriously, Rezza. I had to get some sleep before I came back.


    I am more partial to the 'alternate plane of existence' theory.

    And also how do we know that when hitler 'committed suicide', he wasnt assassinated by someone from the future? Or freakin Kennedy?

    Maybe Kennedy would hav started a nuclear war a 'la 'Terminator 2' and he was assassinated by a robot(t-800 grade) from the future? That might explain the rapidity and accuracy of those shots, which mind you, was astounding.

    Or maybe the guy on the hill was from the future, and knew that Oswald wouldnt have killed him with those two shots, so he went back in time to finish him off?
    To stop the war, of course....

    Or maybe we've been doing all of that as of recent and we've just been royally ****ing up some other plane of existence, and Earths 2, 4, and 9 are all just smoking balls of rubble?

    Hmmm....

    Nahhhhhh!

    ChrisH said it perfectly.

    1. We can't travel in time.

    2. The slightest change in time would cause terrific differences...you never know how moving one rock out of its place can change the course of history.

    3. If time is continuous, if time travel is possible, then our present world would constantly be changing because someone in the future is ****ing with time, right?

    The repercussions and even the possibility and ways of time travel are quite intriguing but easily the most brain wracking.

    Yet. That doesn't mean that a "sufficiently advanced" technology couldn't.

    2. The slightest change in time would cause terrific differences...you never know how moving one rock out of its place can change the course of history.

    That would be proportional to the amount of time between the event and the traveler's present. Going back ten years and killing a cockroach wouldn't do much, but going back ten million years and killing a cockroach would probably cause big problems.

    The further in the past the change is, the greater its effect.

    3. If time is continuous, if time travel is possible, then our present world would constantly be changing because someone in the future is ****ing with time, right?

    The hypothetical paths that particles trace through space-time (called worldlines) can't be broken. So no, once an event has happened, it has happened.

    This doesn't preclude the possibility of the alternate outcomes being expressed as other probability functions, though.
