From Columbia mathematician Peter Woit’s Not Even Wrong blog:
Today I happened to come across a really wonderful discussion there though, and wanted to draw attention to it, even though it’s from a year ago. It’s entitled A View from an Ex-String Theorist and consists of a long piece by someone who has recently left string theory, as well as some answers to questions asked by others. If you want to understand what string theory looks like these days to good theorists who are working on it, read what “No_More_Strings” has to say.
The suggestion that “string theorists” should stop calling what they do “string theory” is an excellent one. … If you didn’t have to start every grant application by explaining that you’re motivated by “our best hope for a theory of everything”, you might find it easier to work on something quite different, with no relation at all to quantized strings. More.
In other words, the best multiverse theory going is a bust.
But don’t expect that to make any difference when pop culture needs the multiverse so badly.
