What specific event can initiate the collapse of a cold, dense molecular cloud?
Answer
A shockwave from a supernova
Molecular clouds are generally stable and do not collapse on their own. However, external disturbances can force these clouds to lose their stability. A significant event, such as a shockwave passing through from a nearby supernova or a collision with another cloud, provides the necessary force to disturb the cloud's equilibrium, causing localized regions within the nebula to collapse under their own gravity and eventually leading to the formation of stars.
