This is the most remarkable pile of junk I have ever read from a supposedly educated cosmologist. I guess 'drivel' is the best description. Unproven String theory has 10^500 solutions and inflation also has several solutions. Fairies at the bottom of the garden or grantsmanship? and Discover mag foists this stuff on an scientifically uneducated public.
