Black Hole Dynamic Laws

Laws describing the interaction of black holes and their surroundings.

  1. The first law of black hole dynamics states that the conservation laws of mass-energy, electric charge, linear momentum, and angular momentum, hold for interactions between black holes and normal matter. This is analogous to the first law of thermodynamics.
  2. The second law of black hole dynamics states that the sum of the surface areas of all black holes involved can never decrease during black-hole interactions, or interactions between black holes and normal matter. This is analogous to the second law of thermodynamics, with the surface areas of the black holes being a measure of the entropy of the system.
