> Yes. The BB has to be applied to a finite volume. Indeed it seems
ridiculous, intuitively - the volume of the universe is quite likely
infinite, so we can apply the BB on larger and larger scales for as long as
we like (in theory) - and if we do so, we will presumably find that we
reach a point where the information content we derive for the interior of
that volume is insufficient to account for its contents. (Or does something
always prevent that happening in practice - is this the point at which we
reach a "cosmic horizon" ? Does the BB have an "information protection
conjecture" that makes the universe safe for information theoreticians?)
