What external event is widely believed to have triggered the initial compression and collapse of the stable solar nebula?
Answer
Shockwave from a nearby supernova explosion
Scientists widely believe that an external event, specifically the shockwave from a nearby supernova explosion, compressed a section of the gas and dust cloud, disrupting its equilibrium and initiating the collapse.
