Been asking this since 1994.


50,000 years have passed since Colony spaceship A and Colony spaceship B launched from Earth. Like in a star trek episode, they all reverted to barbarism, and then regrew a new technological society. Forgot where they came from, and what theyre doing. Theyre big colony ships.

Colony ship A gets on the radio and finds out that they are 1 light-year away from Colony ship B. They start commmunicating with eachother, and discover they are also at rest with eachother. They decide to join forces, but Colony ship B's propulsion system is broke. So Colony Ship A then accelerates REAL FAST at 99.99999999999999% the speed of light in 1 minute to dock with Colony ship B, 1 year later Colony Ship A decelerates and then docks with the other colony ship.

So according to relativity colony ship A only aged a few hours, while Colony Ship B aged an entire year.


------B ----------A


Some guy on Planet C thats monitoring the entire situation, notices that Colony ship A and B are wizzing by at 99.9999999999999999999999% the speed of light. Planet C sees that A decelerates to zero, then reaccelerates to 99.99999999999999999% the speed of light to dock with B. PLanet C notes that B experienced time dialation the entire time.

So what is it?

A) A new universe is created for Planet C that says Colony Ship B experienced time dialation.

B) Each particle in the universe has a history log showing every velocity change, so paradoxes like this cant happen.
