The macroscopic hidden logic in the evolution of astronomical telescopes, from the days of Galileo, points towards a cylindrical horse shoe design, resembling the fork. This design has the advantages of both equatorial as well as altazimuth mounts; but it inherits pointing problems inherent in the current logic of evolution. Whereas the orientation-analysis of stellar objects reveals that in spite of: (1) the lateral shift of the telescope due to spinning and two orbital motions of the earth and (2) the `big-bang expansion' of the universe, we can refer multi stellar objects simultaneously for error free offset tracking. The emerging fundamental logic demands no references to earth which is seen as a rattling platform and hence it circumvents the pointing problems caused by gravity, wind, ground noises, atmospheric refraction, wobbling of earth, etc. The resulting new concept telescope has the following features: (1) It is floated on multi layer air cushions; (2) two bright stars are used for auto guiding; (3) the central shadowed portion of the primary mirror is utilized as the reflector of guide field; (4) telescope shape is spherical; (5) tube is of classical Serrurier strut design and (6) four to eight folded Cassegrain stations are located around the primary mirror.
