Unless you believe that QM necessarily entails a multiverse, in
which case they exist somewhere.
Do we know that? If we know 2+2=5 doesn't hold in any universe, how
do we know about complex things like fire-breathing dragoons.
That's something that bothers me about everythingism. Lots of
things are impossible in QM, like cloning an unknown state. Bruno
says Newtonian physics is impossible under comp (because there's no
FPI). So I think some agnosticism should be spared for "everything
happens somewhere".
Agreed. But I guess people always means everything consistent. "2+2=5"
is just inconsistent, or it means something else than what we mean by
such expression (and it is a wordplay)

What else could maths be, apart from abstract relationships between
numbers?
They could be the ur-stuff of a TOE. Bruno says they're not stuff -
but then I don't think "stuff" is any better defined that "primitive
physical".
Primitive means "assumed necessarily in the TOE. With comp we don't
assume particles, or space, or time, usually assumed in physical
theories.

(Maybe that word "abstract" causes problems? It's possible (if comp
is correct) that "abstract" relations are more real
than real ones.)
