These kinds are designed and computer programmed to produce simulations. They are employed on the Virtual Newton Telescope, the William Herschel Telescope, the Hubble Space Telescope, etc. (Hubble repairs in Dec. '99 included \""the installation of a new 'brain'...swapping its old computer for a new one.\"" Now we can oooh and aaah at the simulated images programmed into it to prepare us for the pre-planned super dazzling virtual reality \""discoveries\"" of evolving life forms from \""out there\"". Reports of Hubble discoveries \""as distant as galaxies 10 billion light years away' (Give us a break, please!) are products of pre-programmed Saganesque hallucinations, i.e., lies. Viewing computer prepared objects produced by funny mirrors and spectroscopic ultra violet tricks may be cool, but it ain't real.
