I'd not totally rule out some of his ideas, such as 'evolution of universes', 'natural selections in universes'. Both theses ideas, seem to me, may have come from observations of natural things on this planet and in space.<br /><br />I haven't read any of his books, but like to read 'Trouble with physics'. This is what I have heard so far is an anti-string theory book. I'll throw any theory into trash cans if it says from the current knowledge of the cosmos, "This is exactly what happened". <br /><br />Another thing that beats me is when people talk about intelligence, they always attach it to a 'life form' as we know it. Intelligence in other universes, if there is one, may not be in the same shape and form as we call 'life'.<br /><br />BTW, Lee's quantum loop gravity, IMHO, is another theoretical rant like string theory.
