This debate has been cross-posted to sci.astro.amateur, sci.astro.planetarium,, and alt.paranormal as CNN did not choose to list sci.astro among the Usenet sites where information on Hale-Bopp could be located. Check

You're admitting that you had NO actual orbit to base your statement on, so lets concentrate on what you describe as "a set of orbits similar to the best determined orbit of HB". What ACTUAL orbits are similar? What ACTUAL orbits did you use? And while your listing those actual orbits, if in fact they exist, please tell us when that orbiting object was OBSERVED to be returning last to the Solar System? What we anticipate is that you are either

  1. not using actual orbits or that you are
  2. inserting orbits of what you assume to be repeating comets, having no documentation on their last visit, and
  3. inserting the speculative period of these speculatively returning comets to cobble up the speculative return date of your fraud Hale-Bopp!

Is this not true?
