#6 A Brief History of Time - Black holes

Updated: Jul 31, 2023

Chapter 6:

  1. Formation of a black hole

    1. A large amount of gas starts to collapse in on itself, after the pressure of the heated gas balances the gravitational force, a star is formed

    2. A star can collapse to a white dwarf, a neutron star, or a black hole( depends on its mass)

    3. The size and shape of a black hole only depend on its mass and rate of rotation, "a black hole has no hair"

    4. The number of black holes is high, since there are a lot of stars collapsed

    5. Black holes glow like a hot body, the smaller they are, the more they glow
