WebSep 25, 2024 · $\begingroup$ Wikipedia: “Although the symbols $\hat H$ and $ \psi \rangle$ may appear familiar, their interpretation in the Wheeler–DeWitt equation is substantially different from non-relativistic quantum mechanics. $ \psi \rangle$ is no longer a spatial wave function in the traditional sense of a complex-valued function that is defined on ... WebThe equation for canonical gravity produced by Wheeler and DeWitt in the late 1960s still presents difficulties both in terms of its mathematical solution and its physical interpretation. One of these issues is, notoriously, the absence of an explicit time. In this short note, we suggest one simple and straightforward way to avoid this occurrence. We go back to the …
WebAug 22, 2024 · The Wheeler-DeWitt equation provides the probability distribution for the cur-vature perturbation, the gauge invariant quantum uctuation of the in aton. From this, we can nd a tower of power spectra which is not found in a perturbative approach. Since the power spectrum for the modes that cross the horizon contributes to the uncertainty in the 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
