Is this where the cosmological principle's uniformity and isotropy take over? Straightforward cosmological schemes do predict upper limits to the scales of perturbations that could have reached significant amplitudes by now, but after seeing the notion of inflation show how to grow perturbations once thought to be impossibly large, having data always beats having pure models. .....
