    What load of crap ass is this? I saw this article posted on another forum.

    The first time travellers from the future could materialise on Earth within a few weeks.

    Physicists around the world are excitedly awaiting the start up of the £4.65 billion Large Hadron Collider, LHC - the most powerful atom-smasher ever built - which is supposed to shed new light on the particles and forces at work in the cosmos and reproduce conditions that date to near the Big Bang of creation.

    Regardless, it sounds pretty stupid.

    If time travel was already possible, we'd most likely have met somebody from the future already ;o

    You may just not know it

    Well I guess they couldn't come even if this machine works for time travel purposes. They claim it can cause wormholes at sub-atomic levels. You'd have to be a midget to fit in.

    Just guessing but I think some people believe this a real historic moment for mankind, thus the interest of time travellers from the future.
    All that belongs to human understanding, in this deep ignorance and obscurity, is to be skeptical, or at least cautious; and not to admit of any hypothesis, whatsoever; much less, of any which is supported by no appearance of probability...Hume

    don't get your hopes up though, it would be very unlikely we'd ever meet anyone from the future, considering that it could possibly interfere with their time line and such.

    and as far as I'm concerned, that wouldn't be something they'd want

    Irina Aref'eva and Igor Volovich are based at Moscow's Steklov Mathematical Institute. They have published a paper, not yet accepted by a peer reviewed journal, that considers consequences of the soon to be switched on Large Hadron Collider at Cern.
    They suspect that the LHC could create wormholes and these, in turn, could provide an opportunity for time travel. It would not be possible to travel from the future further back in time to a point before such wormholes existed.
    Their suggestion, therefore, is that when the LHC goes live in a few weeks that this could provide a conduit from the future for time travellers to return to our time.

    Time machines have been created in the future. Unfortunately, in the future there is 1 lawyer for every 2 citizens, this has created a huge legal battle over its use, so it will be tied up in the courts well into the past.

    I don't see the problem with going back in time.

    So, you'll be at a different time position, but the position in space would stay same. (why should it change if we are only moving in time?)***

    If the spatial positon would change during moving back in time, the substance going back in time would change its space coordinates, thus the timetravel never happened. -correction: The timetravel happened, still it would not be noticable.


    ***if every thing stays the same (spatial positions) you won't be able to tell the difference between the different time positions.
    I haven't come to fight my word, but to find the truth.

    There are in fact MANY problems with going back.
    1. Even if we can create a wormhole, how do we know it is stable enough to have matter pass through it completly without it collapsing?

    2. IF the wormhole doesn't start collapsing on us, many X-rays and Gamma rays would pummel us consistintly, and unless we have developed some Anti X-ray, Gamma ray suit, how do we even live inside one?

    3. Last but not least, how do we know this wouldn't affect the spacetime? if you look at what a black hole does to spacetime, what would a wormhole with matter travel completly through it affect it?

    If you have found out any plausible answers to any of these I would REALLY like to know.

    (P.S, Heres the website where i got all this fun info! http://cosmology.berkeley.edu/Educat...q.html#top#top it's a little blackhole research, look at the what is a wormhole bit)
    weeehoo!

    Time travel is impossible.

    When do they think CERN will be operational? Hopefully I wont see a large flash in the sky when they start it up.
    Of all the wonders in the universe, none is likely more fascinating and complicated than human nature.

    If dark energy exists it is possible it could provide enough resitance to the closure of the wormhole. This requires that as the Universe expands the amount of energy in a unit volume actually increases. (This is held to be likely by a minority of physicists, but it remains a possibility.) This increase in energy would, perhaps, be sufficient to hold the wormhole open.

    I don't think we live inside it. We just pass through it. Haven't you seen Stargate?

    We don't. This is a theoretical speculation based upon well founded equations and more tentative derivatives from them.

    Time travel does not violate the laws of physics as currently understood. Therefore you are expressing an opinion, or are in possession of an improved version of the laws of physics. Nothing wrong with the former, but it is not science. Great news if it is the latter. 8)

    ? CERN of course has been operational since the 1950s. The LHC is expected, finally, to come on line in May this year.

    Just an addtion to Opholite's post.

    Whilst the laws of physics don't disallow time travel they do disallow time travel further back than when the time machine is switched on (See "Black Holes, Wormholes and Time Machines").

    This of course gives us the fairly amusing situation that the moment any time machine is switched on the earth would suddenly be drowned with a massive volume of people who travelled back in time to see the historic moment. (Thus potentially catostrophically increases the earths mass, knocking it out of orbit and to a violent solar death :P).

    Personally I don't believe this is possible because of the implications it would have on time being linear and independent of space.
