In curved 4D non-Euclidean spacetime the shortest path between any two points along the space station's orbit is the space station's orbit itself. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* Ill -- You received this message because you are subscribed to the Google Groups "Everything List" group.
