New Scientist on TOE

The new issue of New Scientist discusses the current situation of our field, it does so relatively honestly, and the spectrum of topics is consequently not the most optimistic one: the conjectured large number of solutions of string theory which is called "the worst embarrassment of riches ever known"; loop quantum gravity; taming the multiverse in various ways, and so forth.

Concerning the anthropic haystack, Susskind obviously supports it, referring to eternal inflation, while Witten says:
  • "More work has always given more possibilities - far more than anyone wanted ... I hope that current discussion of the string landscape isn't on the right track. But I have no convincing counter-arguments."
