A new user has appeared, johnny, with the same argumentative style of Gilles.  Upon checking, I found that johnny and Gilles both use the same IP address, 77.202.161.156 (Grenoble, France).  A clue was the email address used: starmanhh@gmail.com (recall Gilles is an astrophysicist).

I have set the new account status to Spammer, and warned others to not waste their time on replying (and why):

Will this be a further issue if he trots out a new email account, now that he knows a viable workaround?

Apologies if I overstepped.

Very irritating re-appearance, basically taking the arrogant position that he has a better understanding of physics than everyone here, and proceeding to make a 'magical natural cycles' argument.  Good riddance (again).

Per your thread comment, he has now magically disappeared!
