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.
