I've watched the video. Susskind re-affirms the notion that the universe is fine-tuned on a very sharp knife's edge in order to permit life - which refutes random claims on this thread that the universe isn't fine-tuned or the fact that there is nothing remarkable about it - hilarious claims.
Then he goes on and debunks the notion that a constant such as G could only have been G, as he states G could have really been anything; there's no reason that gravity could not have been a 100 times stronger - and therefore, abolishing all life on the universe.
Finally, he states that since the evidence of fine-tuning has been established, an explanation is required, and such fine-tuning can be attributed to:
1) God
2) Luck/Accident
3) Multiverse nonsense
He goes and divulges in his theory of multiverse as I guess that's his line of work, much like a priest would have divulged into God, the afterlife, etc. The multiverse is unprovable, unobservable, and therefore, unscientific. It's no more than fiction.
The video simply re-affirmed the premise of the argument, and that's what Susskind did. The theory stuff, is just baseless speculation.
Well come on now!
You introduced Susskind and posted that video (twice!) as evidence from an expert witness.
You described Susskind as "a renowned professor of physics at Stanford University". But now you're backtracking and dismissing the main point he makes in that video as a "theory" that he "divulges" merely because "that's his line of work", but which is "no more than fiction". But he explains precisely why it's not "baseless speculation".
You can't have it both ways. You can't assert that Susskind "re-affirms" the things you like and "debunks" the things you don't like when you agree with him, while also dismissing what he says as "fiction" when you don't agree with him. You mock "the theory stuff", but your whole argument is all about "theory stuff" when you speculate about non-actual universes. You've never observed any universe in which the laws of physics were different, and neither has anyone else - it's purely theoretical!
You also can't say "The multiverse is unprovable, unobservable, and therefore, unscientific. It's no more than fiction" when
exactly the same thing is true of God. You've said yourself in this thread that God is unprovable and unobservable and, necessarily, cannot be perceived or detected by scientific instruments. I think, as it happens, that your reasons for saying this are weak, and you're actually making your case worse than it needs to be, but whatever. If being "unprovable" and "unobservable" makes a hypothesis "unscientific" then theism is unscientific, and if being unscientific makes a claim fiction, then theism is fiction. That's by
your standards. You can't have it both ways. If the multiverse, and for that matter the string theory that Susskind thinks supports it, is merely "baseless speculation", why isn't that the case with God?
You've cited a lot of scientists in this thread, of varying respectability (I can't believe no-one has picked up on your apparent endorsement at the start of the thread of crackpot Frank Tipler, whose views are in any case wildly divergent from classical theism, and from much of your own views as given in this thread), and you've mocked your opponents for, as you see it, refusing to agree with them about the cosmological constant. So to turn your own criticisms back against you: why should we believe
you on the scientific respectability of the multiverse, and not Leonard Susskind, who is one of the foremost theoretical physicists in the world? What makes you right and him wrong? If you're so certain that his theories are "baseless speculation", what papers have you published in professional journals explaining this to the scientific community? Because anyone able to refute a current theory so definitively would certainly have no difficulty publishing that refutation.
