Well there is another similar interpretation of the voids, which could go under the same subject heading of "multiple bangs" . but in the sense of sequential "little bangs" instead of Penrose's idea of black hole evaporation. He still seems to be tied to the overriding notion of one singular event. Gold and Bondi are responsible for some of the alternative thinking.
Maybe "sequential little bangs" with no singular event - is the same thing as Penrose describes, under a different name; but if so, he should give credit. Penrose has identified concentric circles (spherical voids) within the CMB data - regions in the microwave sky in which the temperature is uniform and markedly smaller than elsewhere, which he sez are the spherical ripples of gravitational waves that were generated when black holes collided or extinguished or whatever. Why not look at the voids as the result of an entire (local) universe collapse? I think Gold's thinking is more accurate - that instead of one big bang, there was never a single event at all . and the voids are instead "prior universes" all of which started with little big bangs; which have eventually opened up voids after long lifetimes (>15 billion equivalent years each). The CMB marks the furthest cumulative expanse of all prior little bangs, which is to say - the limit of a less than infinite expanse. It is like a mirror, and the microwave background we receive is a reflection of the actual limit of space. Not only that - many "galaxies" we see in extreme red-shift are reflections from that same "mirror" - and NOT direct light sources, since are no longer there ! For some reason, many observers seem to fear the implications of a spatially limited universe more than an infinite one. The proof of this, and especially of the "no longer there" claim - will come when computers have completely mapped out the universe, probably within the next decade; and in a future automated secondary survey of the 'old timers' - quasars of extreme (>10 billion year age) we will find a "disappearing act" ! That may have already happened, yet the grad student who observed it has not had the courage to come forward with the evidence . since this evidence can easily be confused with human error.
