(This hunch, is Speculative and not yet well thought yet). The Basis of this, is that 64 AU Corelates with the Geologic record of the Dinosaur Extinction. ask yourself these Questions: the Chess Math 64 SQ'rs, the Retirement age, The Computer Process speeds... Their are a lot of, (Heavy in Magnatude), constants too Human use, that come in at 64, and to Say it with 64 AU Relates it well to the Earth. ____ Finding such an object is beyond my Capability, i wish you luck.
