Pauli Exclusion Principle (W. Pauli; 1925): No two similar fermions in a system, like electrons in an atom, can contain an identical set of the quantum numbers.
Bell's inequality (J.S. Bell; 1964) - The quantum mechanical theorem that explains that if the quantum mechanics were to rely on the hidden variables, it should have non-local properties.
Schwarzschild radius: The radius ‘r’ of the event horizon for a Schwarzschild black hole of mass m is specified by (in geometrized units) r = 2 m. In its conventional units: r = 2 G m/c2
