re: 20 Questions...
Nick,
You are a true scientist and a gentleman. Too many scientists get overly attached to their theories, and refuse to accept any contrary evidence that is placed before them, no matter how compelling. I respect you a lot for not being one of them.
That said, even if Mars did have a Blue Mars phase, I suspect that many of the dynamics developed in your White Mars model will still have much to tell us. Probably the truth about Mars involve elements of both, with a few extra ingredients thrown in that nobody has thought of yet.
Regards,
Nathan.
