Van Vleck and Weisskopf 1, in an interesting paper, have shown that the well-known Lorentz formula for the shape of a spectral line is incorrect except at frequencies close to the resonance frequency.
Black hole spin, or angular momentum, is a fundamental property determined by the rotation of the black hole's event horizon, influenced by the progenitor star's rotation and conserved during collapse ...
