This week of advanced science talks at the lab culminated in a lecture by Gross who offered a note of apology about the string theory of reality, to which he has been a major contributor
"It hasn't led to any big observational payoffs," he said.
I think that's a huge understatement. I think most of the audience probably feels the same way as this comment, because I certainly do:
A member of LANL's Theoretical Division, astrophysicist Salman Habib said after the talk that string theory remains difficult to assess.
"It's a funny field to look at from the outside because it has yet to connect with the outside world," he said. "Mathematically, it's very pretty and theorists like to do fundamental mathematical computations, but they have not led to any big observational payoffs so far.
