Consider what Stanford physicist Leonard Susskind, one of the architects of the string-theory multiverse, has himself said about the underlying impulse behind the construction of this immense theoretical superstructure. “If, for some unforeseen reason,” he says, “the [string] landscape turns out to be inconsistent—maybe for mathematical reasons, or because it disagrees with observation,” [then] “as things stand now we will be in a very awkward position. Without any explanation of nature’s fine tunings we will be hard pressed to answer the ID [intelligent design] critics.”
