Stu the fraud in action... check out this specious argument...
Stu said...
"String landscape itself does not include a Multiverse proposition. Multiverse is an extension from string theory."
his argument sounds good, like a person with the balls to make such a declaration must understand the science....
but... the reality is... stu's statement is dead ass wrong. Susskind coined the term Landscape to describe the results from string theory.
Landscape and multiverse are virtually the same speculation.

Not one to despair over lemons, Susskind finds lemonade in that insane-sounding result. He proposes that those 10500 possibilities represent not a flaw in string theory but a profound insight into the nature of reality. Each potential model, he suggests, corresponds to an actual place - another universe as real as our own. In the spirit of kooky science and good science fiction, he coins new names to go with these new possibilities. He calls the enormous range of environments governed by all the possible laws of physics the "Landscape." The near-infinite collection of pocket universes described by those various laws becomes the "megaverse."
Susskind eagerly embraces the megaverse interpretation because it offers a way to blow right through the intelligent design challenge. If every type of universe exists, there is no need to invoke God (or an unknown master theory of physics) to explain why one of them ended up like ours. Furthermore, it is inevitable that we would find ourselves in a universe well suited to life, since life can arise only in those types of universes.
