Science is learning that there are a succession of big bangs, and the universe had no real beginning.

Another nail in the coffin for the need of a prime mover.

Sounds like a return to the old idea of an "oscillating universe".
First it expands then stops, then collapses onto itsself, then explodes again.

These suppositions are highly speculative. How would they be verified empirically? Could they be falsified empirically?

Hi,

You have to take a look at the work of Sir Roger Penrose (Oxford, UK). No need quantum mechanics machinery, just based on the Weyl Curvature and conformal geometry which is more fondamental than the metric one needed in Einstein General Relativity.
This is in a sense "classical", no need quantum gravity to treat the big bang problem.
I admire Roger Penrose for several years!

Experiments could be done by observing at the CMB. And more precisely, looking for some circle patterns in it. These circles could come from gravitational radiation emitted in an previous universe, existing before the big bang of our present Universe.
Penrose calls these various Universe (previous one, future one, present one...): AEONs
These circles could be seen as the circles made by the raindrops on a puddle...

:)
