Inventor of string theory Leonard Susskind, for one:
If, for some unforeseen reason, the 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 critics.
– as quoted by Amanda Gefter in New Scientist Magazine, December 17, 2005.
Here Bill Dembski notes that Susskind told Alan Guth “You know, the most amazing thing is that they pay us for this” and that Nobelist David Gross admitted, re string theory, “We don’t know what we are talking about.”
Evidently, it’s not important that they know what they are talking abut, as long as they know what they are not talking about.
