Is the Universe really this complex?

26-dim bosonic string theory, based on the Monster
(Vertex Lie Algebra)?

Are mathematical physicists merely applying the
absolutely hardest math that they can find, or
is all this truly "out there"

PGH

we'll never know what is 'out there'. the best we can
do is to set up
some model and see how well it matches the
experimental data. in
principle it doesn't matter how complex the model is,
as long as it
works in a sense that (a) it can model the observable
phenomenas and
(b) it can predict some phenomenas yet to be
observed. My
understanding is that the major problem with string
theory is its
'prediction' part.

Right, in fact there may be no "out there" out there.
I know that, for example, with lattices, they are a bit of a fiction, in the sense that they are discrete, but useful as models.

I also wonder if some of the math is somewhat blown up, so that one can distill down from that to an essence which is more useful. In other words, there is a certain amount of overhead neccessary to get a model which has relevance?

The Leech Lattice as a blown-up version of S(5,8,24)
comes to mind, but then again, I still don't even
see why 24 -> 26 dimensions (bosonic string theory)

And so forth

PGH
