General relativity predicts that time ends inside black holes because the gravitational collapse squeezes matter to infinite density.
A star's life begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements.
Doing so helps prevent the gravitational collapse of the airway.
Such a fusion process is triggered by heat and pressure generated from gravitational collapse of hydrogen clouds when they produce stars, and some of the fusion energy is then transformed into sunlight.
This solution laid the groundwork for the description of the final stages of gravitational collapse, and the objects known today as black holes.
When a main-sequence star consumes the hydrogen at its core, the loss of energy generation causes its gravitational collapse to resume.
