back to article Time travellers outsmart the NSA

If there are time travellers around, they're being careful not to leave their fingerprints on the Internet. That's the conclusion in a paper published at Arxiv, put together by Michigan Technical University physics professor Robert Nemiroff and PhD candidate Teresa Wilson. They searched the Internet for “prescient” signatures …

    Any time traveller would not to leave any noticeable traces, because they either can't, or they don't want any other time travellers to easily find those traces e.g. some kind of opponent or Time Police.

    The best changes would be very subtle 'surgical' tweak, which would cause limited unexpected damage.

    It could be simply

    That such as Twitter and Farcebook are but mere blips that vanish in the night like other sites we remember used to be popular and have gone into oblivion.

    Mine's the one with the long scarf and keys to the blue box.

    I used to date a time-traveler...

    But that's all in the past now...

    Actually our future descendants will know how to travel back in time.

    The problem will be, that they won't find a way to alter their spacial-position at the same time. Therefore all their travel-back attempts will land them in the middle of the void of space, not where their start point used to be. Their planet, solar system and galactic arm hasn't yet reached the point at which they started their journey.

    There's loads of them floating around out there somewhere, deep frozen....

    We're here!

    Looking for a prescient post?

    Time travelers do indeed exist. Just look at the NANEX data just prior to any announcement by the Federal Reserve.

    Won't work anyway.

    It will find lots of false negatives, such as people like me, who merely give the impression of being from the future, by the relatively simple action of predicting it.

      Will work everywhere and especially well in busying pleasure for treasure and drive

      Look out for those who are perfectly enough prepared for futures predicted but not too oft led with distinction to sustainable fruition and growth. Cities and Markets have a Novel and NEUKlearer HyperRadioProActive Meme to Chill Out with there in Live Operational Virtual Enterprise Zones.

      That dictates that the likes of NYSE/FTSE/NASDAQ/ accept a catastrophic hit requiring Systems Rebuild, rather than suffer Degradation and Slow Ruination and Operations Malfunctions.

    Not enough of them

    If these researchers were seriously wanting to think this through, what makes them think that the (probably) tiny number of time travellers would come to this period, be spending time using our primitve and slow internet to communicate or have anyone online to comminicate with.

    But I rather doubt that they were being serious - even with grant money to squander.

    A timehonoured interpretation

    'They focussed on mentions of Comet ISON, and Pope Francis'

    There is no need for time travellers. Just interpret the prophecies of Michel Nostradamus (1503-1566) in the "correct" way.

    Time travel is possible, visit the Cosmology tab at the Faux Science Slayer website for errors in the 'big bang' hypothesis and the reasons why the Rotating Universe Model has been suppressed for sixty years.

    they ARE here

    and I replied to the # tomorrow, it should be there yesterday :o)

    as for time travellers, you really need to go into historical incidents, and I nominate the man on the grassy knoll as time traveller #1

    or if it WAS the future, and you wanted to go back to a specific place, you would need to have a geographical location down tight, OR a major man made feature that has stood already for 000's of years

    so off to Egypt then

    who will fund me ;o)
