SPIRAL cosmological redshift hypothesis and cosmology model in theory does not require hyper-dense proto stellar formation, just that the proto-stars existed by he cosmic inflation expansion event. However from my limited perspective the natural observations align best with proto-stellar formation being hyper-dense with a proportional expansion, during a /the cosmic inflation expansion event, hypothesized in SPIRAL..
So assume SPIRAL and hyper-dense proto stellar formation.
How could the scientific process have worked if this is the actuality?
What factual natural observations appear to align with this?
What if any factual natural observations might precluded this?
