What in the theory suggests that landscapes are a problem? Is there

preconception/hope of physicists who've spent a big chunk of their
lives looking for a unique theory?
But that would be a problem for comp. Comp predicts, at first sight,
that the physical reality is unique, and the same for all universal
machine. If we find an empirical reason for believing in cluster of
different physical realities comp might be in trouble. Physics is
unique because, below our substitution level, it is somehow a sum on
*all* computations, by the first person indeterminacy. It is weird,
and this might point on some reason to believe comp false. With comp
physics is determined entirely by arithmetic (or computationally
equivalent).
To me, the effort of finding some mathematical explanation for why
only one set of physical law can be is a lot like the Copenhagen
theory's attempt to rescue a single history, despite that nothing in
the theory or the math would suggest as much.
Not sure. Copenhagen and Bohm, try to select a model, or a solution of
an equation among many. The selection is at the level of the model (in
the logician sense), not of the theory. The theory QM might suggest
that in showing the interferences of the solutions of the equations
(through superposition), but the first person indeterminacy does not
lead to much choice, in comp.

Stephan,
I solved the landscape problem by assuming that each monad was
distinct
consistent with the astronomical observations that the hyperfine
constant
varied monotonically across the universe.

Good! Now to see if there any any other possible explanations
that do not have the landscape problem...

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.
