text: When the pressure and temperature in the core become great enough to sustain nuclear fusion, the outward pressure acts against the gravitational force.
text: Ultimately the temperature becomes great enough within the condensation for nuclear reactions to begin, thereby giving birth to the Sun.
text: Within 50 million years, the temperature and pressure at the core of the Sun became so great that its hydrogen began to fuse, creating an internal source of energy that countered gravitational contraction until hydrostatic equilibrium was achieved.
