    Hi, i have recently made a video VIA YouTube on what you would do if time travel was possible.

    First of all, it hasn't yet been established that neutrinos can indeed travel faster than c. An explanation for this apparent result could still be forthcoming. Further, the result would also need to be confirmed through further experimentation before anyone could legitimately make such a claim.

    Second, even if neutrinos can travel faster than light, it doesn't follow that time travel to the past is therefore somehow suddenly magically possible.

    To answer your primary question however, if it was possible to travel back in time and change something, I wouldn't. Not if there is only one time-line anyway. There are problems with the world right now of course, and my own life is far from perfect, but there's just no telling how things might have ended up if even some seemingly insignificant detail had been different. If however we live in some kind of multiverse where all possibilities are realized anyway, or if meddling with the time-line causes it to branch off into an alternate time-line (leaving the original intact) I might be more inclined to tinker. Maybe. And if I did, I'd most likely endeavour to prevent a great atrocity that caused the death and suffering of countless individuals, and there are plenty of those to choose from.

    Indeed this is something often misunderstood by scifi buffs. Lightspeed is a measurement of distance and how long in regards to time that light takes to travel that specific distance. Going "faster than the speed of light" just means travelling the same distance quicker, it doesn't reverse time.

    In fact the consensus tends to consider time to be "one direction only", which means there is no reversibility.

    There is an alternative theory, however it takes the consideration that the universe is emulated within a computer network and it applies the understanding that the planar logic (how interpreters run with one directional time arrows) applied to how current computers architecture handle data asynchronously would have to be re-written to handle "bi-directional data entities". (Namely creating data with an inverse "flipside" that flows from end to start that parallels the normal start to end entity.)

    Of course such a rewrite undermines physics as a whole, since it can all potentially be rewritten to suit any given situation.

    I think that time can be traveled, just like the wind. Time is considered an element, like water and fire. We notices its effects and that its part of the forces that effect us. So even if people don't feel your on the right track, I strongly urge you to listen to your intuition and never give up on the idea. Because it is possible, once we learn what time is.

    As a side note: I've traveled the future and I've traveled to others present time outside my body. If its possible for me to than there is something to consider with time. That its possible that past, present and future happen all at once.

    Possibly we are born in this element with the ability to block out the past and future to be in the now. Some how are ability to block doesn't all ways work, so thats how I somehow get remote viewings of future occurences. as a second thought, time could be slipping back into itself.

    I am sure time traveling is possible but only to the past.

    The connection between exceeding the speed of light and time travel most likely originates from the idea that as you approach c time slows down until at c it stops. Thus if you exceed the speed of light (c), time turns back on itself and you have time travel. Not really very likely or the neutrinos in the recent CERN data would have arrived befor they left not just early.

    Time can only be traveled in one direction, into the future and we seem at least for the present to be limited in how fast we travel into that future to the seconds, minutes, days and years, as we currently experience them.

    There is no going back except in our thoughts, memories and dreams and going forward seems limited to how well we can predict what may happen next. If we were any good at that we would all have bought Apple stock at $5 and held it!

    Well, given that we can travel into the future right now (just go very, very fast) I think we're covered, then.

    Ah! but that's the point you'd never achieve a stop and if it did, it wouldn't reverse, you would be left with an absent space devoid of anything where there would be nothing to have continuity from that point on. So in essence if you managed to get to the point that everything ceases to exist, "you just deleted the universe, you muppet!" (That's a figurative depiction on what to quote someone if they achieved this and not an Ad Hominem aimed at you).

    Like I postulated that isn't necessarily true, it's totally dependent on whether localised physics can be malformed to create specialised abstractions of currently defined constants. Obviously though this isn't going to proven/disproven until it's been fully tested.

    T3 (Time Travel Theory)

    Axiom 1: Time travel to the future at the rate of 1 hour per hour is consistent with the general notion of 'time'.

    Axiom 2: Time travel to the further future (as in the 'twin paradox') is consistent with Einstein's Relativity theories.

    Axiom 3: Time travel to the past is logically possible.

    Axiom 4: Time travel to the past is consistent with the known laws of physics.

    Axiom 5: You cannot 'change' the past.

    Axiom 6: You may be able to 'influence' the past.

    Axiom 7: You can only influence the past if it does not allow the 'bilking paradox'.

    Notes:
    1. The difference between 'changing' the past and 'influencing' the past can be illustrated with the 'Dr. Who paradox'.

    2. There is an interpretation of quantum mechanics, called the 'Transactional approach' which involves influences on the present from the future.

    Hypothesis 1: Time travel to the further future is technically difficult (as of the year 2011).
    Hypothesis 2: Time travel to the past is mentally difficult (it affects the mind).
    It should be called 'Time ravelling'.

    Thus you're not going to get hordes of 'time ravellers' visiting historic events, let alone your back yard.
    You're not going to witness 'Tom Baker style look-alikes', they're going to be discreet.
