The volume of the multiverse is generally thought to be infinite. Even the volume of our universe may be infinite. If you want to apply the Beckenstein bound, consider the observable universe since its boundary forms an horizon relative to us.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 theBB on larger and larger scales for as long as we like (in theory) - and if we do so, wewill presumably find that we reach a point where the information content we derive forthe interior of that volume is insufficient to account for its contents. (Or doessomething always prevent that happening in practice - is this the point at which wereach a "cosmic horizon" ? Does the BB have an "information protection conjecture" thatmakes the universe safe for information theoreticians?)
