Its (just) an analogy just for BH's..

Yep AA, this new "river" BH model is a re-hash of the old Painleve-
Gullstrand metric that was discussed here several times (with credits
to Zinni). It's carefully couched as an analogy so as to never imply
anything is *literally* flowing.

Yet space is declared to *expand* from the instant of the BB. So how
pray tell, does it expand *without* flowing?

As flows the black holes, so flows the universe!
