Once the sun and planets took shape, heat became readily available in the form of solar radiation, asteroid impacts, and gravitational pressure.

太阳和行星成形后，太阳辐射、小行星撞击以及重力压力继续提供着热量。

Eventually, the mass of the dark matter star would exceed its "Chandrashekar limit" - beyond which a star cannot withstand gravitational pressure.

最终中子恒星中暗物质恒星的质量会超过它的“钱德拉·塞卡极限(Chandrashekar limit)——超过了这个极限值，一个恒星就经受不住引力所引起的压力。”

If the gravitational pressure overwhelmed the neutron degeneracy pressure, the neutron star would be crushed into a singularity, producing a black hole.

如果引力压过中子简并压，中子星将被压成一个奇点，变为黑洞。

The process naturally occurs in the core of the Sun where huge gravitational pressure allows this to happen at temperatures of around 10 million Celsius.
