What physical mechanism allows nebulae to function as 'stellar nurseries'?

Answer

Gravitational forces overcoming internal pressure, causing inward collapse

Star formation occurs when gravitational forces within dense knots of gas and dust become strong enough to overcome the internal pressure, leading to material collapse, core heating, and the ignition of nuclear fusion.
