Exactly, MM, if I may call you that. It's my belief that as the Universe contracts, it is refilled by incoming dust and whisps of hydrogen. In a void, a black hole will be forced to eat its Aquisition Disc. In a particularly rich area of space, a black hole's disc will probably grow. I believe Mable's disc is growing - in this case, tho', the expansion is limited, and in no way resembling any Big-Bang. Hence the 'newly arrived material.' Beyond that, I can only repeat myself - we're Expanding Inwardly, into Mable. Thanks for all your invaluable help. You have given me much room for thought.
