and you lot can't interpret :uhoh: smilies :dozey:
It's been donkeys since I studied basic relativity theory - can't remember whether it was in school or in 1st year physics-, but rest assured that human time travel is for all practical purposes ( like getting yourself a life :p : ) impossible, and will remain so unless your friend Einstein missed something we don't yet know about. :)
Cosmonaut Sergei Avdeyev spent a total of 748 days on the Russian space station Mir during three separate missions. Because Mir was moving relative to Earth, it was also a time machine. Avdeyev is 0.02 seconds younger than he would have been had he never traveled in space.

Or you could say he traveled roughly 0.02 seconds (20 milliseconds) into the future.
As a formula

sure, so now use your formulae to work out how many days he'd have to spend on mir to rejuvenate some practical amount :)
Id say a Railgun would be the best bet, however they are still in development.Quote:

that happened in the film 'the mexican', a guy who brad pitt was with suddently died, and when he looked at him he saw a bullet had fallen from the sky and went straight right in the middle on his skull...nice.Quote:

Lets go back to the original here and now you. So you've travelled 5 years and asked that question, great...nice one. So you carry on with the rest of your life. In 5 years, you'll know that you'll get a visit from the 5 years younger version of you (as you travelled originally to the older, which is who you are in 5 years).
To conclude this ridiculously complicated scenario, if you travelled forward in time, you will be created a parallel universe infinity times over. who knows what would happen if that happened.
a further note, myself and viperman once spent until the early hours, about 4am discussing this whole predicament, forwards backwards, stopping time all of this philosophical stuff.
We got baffled, but we didnt come up with scenarios to prove that it is all impossible. a typical student night you might say
i work with a swedish bloke who comes out with all the american trash talkQuote:
