What primary process must gravity overcome for cloud collapse to begin?
Answer
The outward push provided by various pressures
Collapse commences only when the cloud’s self-gravity successfully overcomes the combined outward resistance provided by internal pressures attempting to keep the cloud puffed up and stable.
