Spacetimes
black hole spacetimes | vanishing angular momentum | positive angular momentum |
---|---|---|
vanishing charge | Schwarzschild spacetime | Kerr spacetime |
positive charge | Reissner-Nordstrom spacetime | Kerr-Newman spacetime |
Quantum theory
The radius of the horizon of a Schwarzschild spacetime black hole of mass is called the Schwarzschild radius,
where denotes the gravitational constant and denotes the speed of light.
Another physical unit of length parameterized by a mass is the Compton wavelength . Solving the equation
for yields the Planck mass
The corresponding Compton wavelength is given by the Planck length
fundamental scales (fundamental/natural physical units)
