The fundamental way a paradox is avoided is by throwing an extra minus side into Euclids formula for finding the hypotenuse of a right triangle and using that metric to calculate distance thus s2= c^2t^2-x^2 (or s^2= - c^2t^2+x^2, it makes no difference which you use as long as you're consistent) where s is the distance in spacetime, t is the amout of time , x is the distance in space, and c is the speed of light. So if event X and event Y are at an equal distance in spacetime for me then they are both on the same hyperbolic structure.* *It is necessary that the space component and the time component have opposite signs because if we used Euclids original formulation all observers would NOT agree that two events are always the same distance apart in spacetime, and you could even disrupt causality by have some observers see you winning the lottery before you bought a ticket. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* o3b -- You received this message because you are subscribed to the Google Groups "Everything List" group.
