going back in time to see the 'true version' of events, has been debated often, the 'uncertainty principle' still applies - the event can be affected by the observation - however I wouldn't be surprised if Incog is also correct with her post - i.e. that 'travel' to the future may be possible, but not 'travel' to the past?
Bob Shaw's 'Slow Glass' stories are good for an illustration of what I mean  |
Its allready possible to travel forward in time, though only by seconds.
Its a fact that when traveling at supersonic speeds time affects you less than it does when you are stationary or traveling at sub sonic speeds.
From what I remember the effect is so slight that 4hr flight might only move you 1 second into the future, so allthough the flight only took 4hrs to you it actually takes 4hrs 01second to everybody else.
Obviously this is useless to us for a practical time machinethough it does shed a tiny bit of light on how time works and may lead to a soloution for making time travel a reality.
