    If it was ever possible, wouldn't someone from the future have come back and told us already?

    Um... I would hope that, if it becomes possible in the future, they will never let us of the present know about it because - let's face it - too many people in positions of authority are self-serving fuckwads and they'd probably only eradicate all existence.

    how do you know?

    If time travel is possible (and theories abound about it being both possible and impossible) why would they come back to this time? to right now? to last week? or the week before? we have lived in an age of absolute cataclysmic boredom, there is nothing of interest besides political bullshit and why on earth would they want to come back for that.

    And assuming they can travel through time, if they were to come back and make any changes it could potentially creat a cataclysmic event in the future including making time travel having never been found possible.

    Also, there are theories that is say someone came back in time, told us about the existence of time travel that a new existence would be created both an existence of things continuing unchanged and unknown (ie, our currant time line) and a new off shot, everything up to this point would be the same but everything beyond this point would be different for the off shot then for us.

    on top of all that, to actually time travel would probably require both massive amounts of energy and unbelievably complicated mathematical equations well above our currant understanding.

    One of the theories I'd heard was that if time travel is possible and ever actually turned into reality, that it may be possible to go forward in time and backward, but not to a point before it was made possible. I pictured it like opening a wormhole into the future that someone from the future could follow back to the point/time it was opened. I have no idea how reputable this theory was - but it would explain why nobody from the future is visiting us around here and now. They can't until we figure out how to do it.

    My own thoughts are that backward time travel causes too many paradoxes / contradictions that it will never exist.

    It's possible for us to go back in time.....but it would be impossible for someone from the future to come back to us.....because the future hasn't happened yet....."Ye canna change the laws of physics Cap'n" icon_wink.gif

    What is time? I don't think time exists, so time-travel is not possible.

    If you can move back into the past then, there will have to be a future.

    Time may not be linear. Of course, it's a made up measurement, like "centimeter," based on a subjective reference frame, meaning the rotation of the earth on it's axis, and it's motion around the sun. Which is rather a bit silly. We don't talk about traveling back in centimeter after all.

    Now, if you COULD go back in time in a time machine sitting in your living room, you would have a small problem when you arrive at your destination time:

    The earth will not be where you left it. Neither will the solar system. Or the galaxy. The movies generally leave this part out.

    True, time travel definitely involves space-travel as well. But it's all just space-time, right?

    That's why you should really only listen to the good Dr. Who. He makes the most sense of it. icon_biggrin.gif

    Eh, not exactly. Space-time is a general term to describe the jello-like universe, according to my friend Chris, who is an astrophysicist. If you travel back in time, your location would remain the same, unless your time-travel device were also a space-ship. There was a really good general article about this in Scientific American ages ago.

    Ever thought that someone coming from the future might get mistaken for someone who is insane and committed to an asylum?icon_twisted.gif

    Time travel is certainly interesting, but it might open doors to parallel universes where things developed very differently (eg. with Hitler winning WWII). icon_confused.gif

    Everything I ever needed to know about time-travel, I learned from ONE man:

    "People assume that time is a strict progression of cause to effect, but *actually* from a non-linear, non-subjective viewpoint - it's more like a big ball of wibbly wobbly... time-y wimey... stuff."

    hehe...time-y wimey...stuff

    This is where you need Carter icon_razz.gif she knows all!

    assuming that we could potentially move back in time, universe expansion (or, in this case contraction) would need to be taken into account, however, over our own history that expansion would be tiny, thus, precision wouldn't be absolutely pivotal, although, you'd need it enough to not end up inside a mountain I'd assume.

    Going further back would be a lot more interesting, how far has not only the earth moved, but, our entire solar system, the surrounding systems and our own sun and more so, does gravity have an effect on our movements through time, the sun has massive gravitational pull, so, would it affect our movements through time and by how much and if it does, other planets and heavenly bodies would need to be taken into account and the more precision you want the more you'd need to know.

    it would be an incredibly interesting thing to do, travel back in time, it would be awesome to see where we started, where we the only ones, was there something more to it...

    Yeah, but the Doctor...he can see everything that was, everything that is, and everything that will ever be. He's inspiring - intrigued by everything, non-violent to a fault...I only wish I could be like him (and yes I'm aware he's a fictional character, lol)

    ...besides, it's bigger on the inside }-P
