A gravitational collapse is the process by which a massive object, such as a star, collapses under its own gravity. As the object's core runs out of nuclear fuel, the outward pressure decreases, causing gravity to overcome it and compress the core. This compression can lead to the formation of a black hole, neutron star, or white dwarf, depending on the mass of the collapsing object. Gravitational collapse is a fundamental concept in astrophysics and plays a crucial role in the evolution of stars and galaxies.
Gravitational collapse is a crucial step in the process of star formation. When a cloud of gas and dust in space collapses under its own gravity, it becomes denser and hotter, eventually leading to the formation of a protostar. This gravitational collapse is what initiates the fusion reactions in the core of the protostar, eventually leading to the birth of a new star.
A white dwarf's stability is maintained by electron degeneracy pressure, which prevents further collapse due to the immense gravitational pull.
The main force that causes a star to undergo gravitational collapse and transform into a black hole is the inward pull of gravity, which becomes stronger as the star's core runs out of fuel and can no longer support itself against its own gravity. This collapse results in a dense, compact object with a gravitational pull so strong that not even light can escape, creating a black hole.
When a black hole collapses, it shrinks in size and its gravitational pull becomes stronger. This process is called gravitational collapse. The consequences of this collapse include the black hole becoming denser and more massive, leading to an increase in its gravitational force. This can result in the black hole consuming nearby matter and energy, and potentially emitting powerful radiation and jets of particles.
An object needs to surpass the Chandrasekhar limit, approximately 2.0 × 10^17 kg/m^3, to develop a gravitational field. This limit represents the point at which electron degeneracy pressure can no longer support the object against gravitational collapse, leading to the formation of a neutron star or black hole.
