Josep, you are unduly hostile for a person who feels he has the facts (i.e., the truer speculations).

I've been an astronomy enthusiast since I was a kid, I took a number of astronomy courses in college (with telescope time in the observatory), and I read a great deal, keeping up with the latest in the field. A whole stack of recent books, plus "Astronomy" and "Sky and Telescope" magazines.

Calling someone an "ass" is a dead giveaway that you feel you are on shaky ground.

Have a nice day.
