Oops. Sorry, I did misunderstand. If they're using anything analogous to
a one-time pad, then of course.

In fact, it would *be* entirely random, which is what threw me off:
Why would anyone ever have a *language* based on total encipherment?
It makes no sense.

I guess I can see that: as you were saying, you could run some machine
at one set of randomly chosen galactic coordinates for one picosecond,
then run the next part of the computation light years away at another
randomly chosen location, and so on.

Sounds plausible. Certainly someone would have to go through
a lot of trouble for this, and I don't see why anyone or anything
would evolve to do it.

Yes. Was that the point? Sorry, I've forgotten what the point here
I've generally said that among the swirling dust clouds and random
particle motions of deep intergalactic space one could eventually
find a set of atoms isomorphic in structure to my brain at this instant.
That was sort of Hilary Putnam's point when he said that any rock
emulates anything. But to me, it's pointless unless an emulation is
driven causally in real time in order to effect a computation.
By the subject line, my claim was that any meaning found in a
communication (or artifact) if in order to truly be objective,
must exhibit isomorphism. Some message that has meaning
which needs an exterior Rosetta stone or one-time pad to
decipher does not have objective meaning. For, as you and
others have said, then anything can mean anything, with the
