Black Hole Radiated Power

The total radiated power of a black hole comes from Hawking radiation, caused by quantum effects near the event horizon.

The total radiated power decreases quadratically with increasing mass.

Formula

QuantityVariable["P", "Power"] == Quantity[1/(15360*Pi), ("ReducedPlanckConstant"*"SpeedOfLight"^6)/"GravitationalConstant"^2]/QuantityVariable["M", "Mass"]^2

symbol description physical quantity
P total radiated power "Power"
M mass "Mass"
