Book: "Dark Integers"
Story: "Luminous"
(The story "Dark Integers" is actually a sequel)
Premise: In reality, mathematical truths are undecided until embodied in a
physical system, until a physical system's state is different depending on
the truth of the system. Fermat's Last Theorem was neither true nor false
until someone actually proved it, thereby modifying the state of their brain
based on the result. Premise: Mathematical truth is restricted to the speed
of light, and hence different parts of the universe might have different
mathematical proofs that are true. Conclusion: Current theories about
integers might or might not be consistent, and mathematical statements might
or might not be true depending on the order in which you try to prove
things. Invent the discovery of such a state in the real world, and discuss
possible ramifications. :-)
A delightful short story, if only for the premise.

Was Greg Egan the author you've touted frequently in the past? I only
recently read some of his stuff. Dark Integers (the story - not the
anthology) was quite good. Perhaps I got it from a link you posted? It's
free to read on Asimov's (magazine) site.
Just about a week ago I read Diaspora (the only book of his that I've
read). It was interesting. Not great, but good enough for me to read
more later. I've heard Permutation City is the one to read.

Yes. I love 99% of his stuff.

Yes. I liked the first chapter of Diaspora best, wherein he describes the
evolution of self-awareness.

A similar SF premise but I can't remember whose it was or the story -
perhaps Asimov ?
That the physical properties of the universe are set by God (or a god ?)
but only when some pesky scientist bothers to go looking at them. The
first time a property is measured there is a large margin of error which
allows time for the deity to determine what the more precise value
should be.
Like Pi - Well its about 3. You know, give or take about 20% That
should keep them busy while I work out the real value.
Then I think it went on that by measuring how quickly the precision of a
measurement could be improved by successive measurements and assuming
that this all works at the speed of light, you could calculate the
distance to heaven. Do this from different locations and you could
triangulate.

LOL! Delightful! Please let me know if you figure out what story this is.

That was me :-) (No, seriously: I love this idea, and have been toying
around with it occasionally for one or two decades by now, and I'm sure
I didn't pick it up anywhere (*). Though I must confess I never wrote
about it :-P)
(* Well, maybe it was inspired by Douglas Adams, and that quote along
the lines of "there's a theory that if anyone ever manages to fully
understand the universe, it will instantaneously be replaced by
something even more bizarre. There's another theory that this has
happened already.")
I find it actually remarkably consistent with quantum mechanics: As long
as you don't look at a particle, it is not at any particular location,
i.e. the answer is undecided. As long as you don't look at how big pi
is, or the charge of an electron, or what atomic nuclei are composed of,
the answer is undecided...

LOL, that's great!

Pretty cool. An example of an actually unprovable truth that isn't
completely contrived:

Ramsey's Theorem in almost english at the start, that might explain why you
might care:

Well, my intent was the take-away that there's actually things like graph
problems where you color the edges of something, that trigger godel, rather
than just a big long artificially-constructed string that nobody otherwise
cares about.
Sort of the difference between the halting problem and some of the actual
useful stuff (like the printing problem, etc) that falls out of it.
I can imagine there's a use for solutions of colored graphs. I can't imagine
there's a use for a Godel string outside of Godel proofs.
