Lee Smolin, what's he got against strings? |
Not being of the physics community, and thus being (what do they call
those things?) ... a lay person, what's Lee Smolin's beef against
superstring theories? Apparently he's written stuff about strings too.
What's his favorite theory instead?

Maybe it has something to do with the notion that string theory is
thirtysome years old and has yet to make any concrete predictions
about nature. He has made many contributions to the theory of loop
quantum gravity:

Ah, ok, thanks for the link, have to admit that I had never heard of
that theory before. So perhaps Smolin's got a reason to detest Strings,
since his Loops aren't getting any airplay.
