{wiki=Gravitational_collapse}

Gravitational collapse is a process that occurs when an astronomical object, such as a star, cloud of gas, or a galaxy, undergoes a significant loss of internal pressure, allowing gravity to overwhelm the forces that hold it up. This leads to a rapid decrease in size and an increase in density as the object contracts under its own gravitational pull. In the context of star formation, gravitational collapse typically begins with a cold, dense region of gas and dust in space known as a molecular cloud.
