String theory predicts the viscosity of the quark-gluon plasma

Hi Richard,
Could you link some sources on this?

Hi guys,
Neither CYM's nor strings physically exist-- instead, they
represent things that exist.
Anything in equation form is itself nonphysical, although the
equations
might describe something physical.
The equations of string theory describe strings. So how does it
follow that strings aren't real. That's like saying a sentence
that describes my house shows that my house isn't real.
I agree that string theory (or any other theory) is a model of
reality and not reality itself. But, if it's correct, it refers
to reality or at least some part of reality - like, "My house is
green." refers to a part of reality, but "My house is blue." does
not.

When and if string theory makes a prediction that is then
found to have a physical demonstration we might be more confident
that it is useful as a physics theory and not just an exercise in
beautiful advanced mathematics. The LHC is looking for such
evidence...
For example, if I live at 23 Main street, 23 Main Street is not
my house,
it is my address.
