I'm also not against the inflation model, which is what I guess you're referring to when you're talking about 'solid physics'. Unless you're talking about the physics the inflation model is stuck into, General Relativity and Quantum Field Theory.
The discussion isn't about inflation cosmology which is pretty well attested, even without the latest data coming about polarisation of the cosmological background radiation, we already had several independent lines of evidence for it: lack of magnetic monopoles, flat spacetime, distribution of the microwave background. And a typical consequence of most inflation models is that there's a lot of little space time bubbles floating around.
The problem unfortunately is that its unlikely that this process could run infinitely into the past, at least not without introducing specially constructed spacetimes. This is not something cosmologists accept, its the accepted approach so far to assume that there won't appear to be anything special to the way the universe is arranged. Its a typical distribution.
