Rainbow (Noon Universe)

Rainbow (Noon Universe)

Rainbow (Радуга, pronounced: Raduga) is a fictional planet described in Far Rainbow by Arkady and Boris Strugatsky. This planet is a part of the so called Noon Universe and presents a planetwide experimental laboratory used by null-physicists (scientists working on null-T, a sort of teleportation used in the Noon Universe since the second half of XXII century). It isn't clear when it was discovered but, presumably, somewhere between 2146 and 2154 AD.

Rainbow is a very comfortable planet with a moderate climate, a calm atmosphere, little seismic activity and a rather phlegmatic native fauna. There is only one continent (in the Northern hemisphere) and some small archipelagos (in the South one, which is covered with an ocean). Remarkably, the coastal line between the southern ocean and the northern continent roughly coincides with the equator.
