How do you even know “Unicorn” is a scientist?
I don't know...don't really care...he/she makes sense & used logical/scientific arguments. I am not playing the "I see your scientist and raise you one "scientist" game...(or "Janes expert" or ???). Bring physics, optics & contrail facts not so-called "experts".
