I am watching a lecture by Susskind on his book The Cosmic Landscape. And he is going on about how "tuned" and unlikely it is. Largely based on work done by Weinberg. He said it was one of the biggest surprises in science and can't be ignored. How fine tuned the cosmological constant is. Is this true? I have read a little on here and people do not seem to be too big on him or string theory. And seem to side with Smolin. What do you guys think of this? Is this fine tuning really the problem that Susskind says it is?
