Gravitational Collapse

Gravitational collapse is a process by which an astronomical object or system of objects falls in on itself under the influence of gravity, resulting in changes to its structure and composition. This can lead to phenomena such as the formation of stars from interstellar clouds, the creation of black holes from massive stellar remnants, or the aggregation of matter into larger structures like galaxies.

Key Points

• Definition: The process by which an object’s internal pressure is overcome by gravity, leading to a contraction and potential densification.
• Examples:
  • Formation of stars from nebulae
  • Creation of black holes from stellar remnants
  • Galaxy formation through the gravitational aggregation of matter

Related Concepts

Dark Matter Non-Collapse: The Lack of Electromagnetic Interaction

Why doesn’t dark matter collapse into black holes?

• Unlike normal (baryonic) matter, dark matter does not interact electromagnetically, which means it cannot form dense objects like stars or planets.
• Instead of forming compact structures, dark matter largely remains diffuse and distributed throughout galaxies.
