In Special Relativity time is diluted by the factor γ which is equal to 1 / √(1 - v²/c²) ; and an object's length will be reduced by a factor of the inverse of γ. So Length contraction reduces the length by 1/γ, and Time Dilation increases the time interval by γ. For example, at 87% the speed of light length contracts to half its original rest length, and time dilutes by a factor of two.* *The bottom line is that when two observers are in relative motion, like the garage man and the car driver are, they measure space and time differently. An event has a position and a time, and the closing of both garage doors is an event, so they will not agree if that event happened simultaneously when the entire car was in the garage or not.* *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* tgc > > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
