For 10 points, name this object which absorbs all electromagnetic radiation incident upon it.
A paradoxical result associated with this object whose name was coined by Paul Ehrenfest in 1911 is in part due to the relationship between frequency and the emitted energy of this object defined by the Rayleigh-Jeans law. That result suggests that at high frequencies the radiated energy of this body goes to infinity. Known as the "ultraviolet catastrophe" other equations which govern this object's properties include Wien's displacement and Planck's Law. For 10 points, name this object which absorbs all electromagnetic radiation incident upon it.
