11. What is the relation between accelerating universe, cosmic inflation, Hubble's law, event horizon, and gravitational collapse ? 12. The gravitational collapse of a star is a natural process that can produce a black hole. 13. That's presumably because of some still-unclear feedback mechanism involved in the gravitational collapse of primordial clouds. 14. :: : Any rotating gas cloud that undergoes gravitational collapse will tend to flatten into a disk. 15. :: : Returning to that sentence, it now reads " the final stages of gravitational collapse ". 16. The condition for gravitational collapse is therefore: 17. The pressure of expanding hydrogen in the cloud slows the gravitational collapse , making it smooth and uniform. 18. Well-developed back-thrust faults, microfractures and gravitational collapse are found in the accretionary wedge of the Manila Trench. 19. A brown dwarf, like a star, is formed by the gravitational collapse of a cloud of gas. 20. It is also a very important quantity in the physics of white dwarf stars against gravitational collapse .
