In the inaugural ICG meeting, on August 11, 2007 at Penn State, Roger Penrose [1] gave a presentation about an alternative to cyclic cosmological models, which needs experimental tests for falsifiability. As discussed by Beckwith, in EJTP [2], Penrose brought up how wave equation, as simplified in flat space could lead to a rising vacuum nucleation field which would engender the pop up behavior as sought in most emergent field models of gravity. The scalar field pop up with certain qualifications is not so startling in itself. Now for the radical extension Penrose brought to bear. Penrose asserted in his ICG lecture that there was a good chance that there was no collapse in future events, but that matter would be eventually sucked up by “millions” of black holes, creating a clean-up of most interstellar matter. The issue to be brought up is how to come up with a mapping for re-combination of the black hole collected material, for a big bang, a topic which was not solved by Penrose.
