The universal wave function or the wave function of the universe is the wavefunction or quantum state of the entire universe. It is regarded as the basic physical entity in the many-worlds interpretation of quantum mechanics, and finds applications in quantum cosmology. It evolves deterministically according to a wave equation. The concept of universal wave function was introduced by Hugh Everett III in his 1956 PhD thesis draft The Theory of the Universal Wave Function. It later received investigation from James Hartle and Stephen Hawking, who derived the Hartle–Hawking solution to the Wheeler–DeWitt equation to explain the initial conditions of the Big Bang cosmology.
