Gravity collapse
Gravitational collapse means that a heavy object falls in the center direction due to gravitational effects in astronomy. If all the other forces produce enough pressure to balance gravity, then the heavier objects will reach a static equilibrium state. Gravity collapse is at the center of universe structure formation. The material that was initially distributed evenly is finally collapsed, creating a system of structures such as galaxies, clusters, stars and planets. For example, stars are created through gradual gravitational collapse of interstellar matter. Compression, as the collapse progresses, increases the temperature until nuclear fuel inside the star begins to burn and stops collapsing. The degree of increase in pressure due to heat offsets gravity and leads to a dynamic equilibrium between these forces. The gravitational collapse of a star occurs at the end of a lifetime, also known as the death of a star. When all of the star energy sources are exhausted, the star starts gravitational collapse. In this case, the star stays in a temporary equilibrium between gravitational collapse of star birth and gravitational collapse of star death.
