What role does high-level turbulence play in actively disrupting large-scale gravitational contraction?
Answer
It injects momentum, dynamically heating the gas and increasing pressure support that halts free-fall.
Vigorous, chaotic motions driven by energy injection (feedback) churn the cloud, injecting momentum which effectively increases the dynamic pressure, thereby halting or resisting the ongoing gravitational contraction if the energy input rate exceeds the dissipation rate.
