In a Stanford University press release today, Susskind promotes the “Landscape”, calling each different vacuum state a “pocket universe”. Referring to people like David Gross who oppose the idea, Susskind says: “More and more as time goes on, the opponents of the idea admit that they are simply in a state of depression and desperation”.
I’m wondering exactly which string theorists have admitted to him their depression and desperation.
It seems that Susskind’s new book coming out in a couple months isn’t about the Landscape, but rather black holes and holography. He’s writing another one now, to be called “The Cosmic Landscape”.
In other news, Witten will be giving a Distinguished Lecture Series in April at the Fields Institute in Toronto as part of their year-long program on the geometry of string theory. Witten seems to have decided that there’s not much to say about string theory these days, since the topics of his talks are listed as “Relativistic Scattering Theory”, “Gauge Symmetry Breaking”, and “The Quantum Hall Effect”.
