Dewitt equation
Webing equation of such a function, and the central equation to quantum cosmology is known as the Wheeler-DeWitt equation. This equation, which the wave function must satisfy, takes steps towards a theory of quantum gravity as it blends ideas from both quantum mechanics and general relativity by Dirac quantizing the Hamiltonian WebThe Wheeler-DeWitt equation is based on the use of canonical quantization rules that may be inconsistent for constrained dynamical systems, such as minisuperspaces subject to …
