| This is a shot in the dark, but since this is my favorite site of toy-playing adults, I was wondering if anyone knew of good playmobil fan sites or databases of sets apart from the official site? Anyone? Anyone? Bueller? Jonathan (24 years ago, 7-Nov-00, to lugnet.off-topic.geek)

| (...) Hi, let's do some math. IIRC T = t/(sqrt(1 - (v/c)^2) where T: time elpased for stationery observer t: time elapsed for moving observer v: velocity of moving observer c: speed of light assuming minimal acceleration. T = 11.5 yrs. Experiments (...) (24 years ago, 7-Nov-00, to lugnet.off-topic.geek, lugnet.space)

The traveler won't notice the slowing of time, since everything in his frame of (...) (24 years ago, 7-Nov-00, to lugnet.off-topic.geek, lugnet.space)

(btw, it's not a 1/x ratio, I think it's closer to a 1/x^2, but highschool was a long time ago...). For the people on earth, (...) (24 years ago, 7-Nov-00, to lugnet.off-topic.geek, lugnet.space)
