The equation attempts to mathematically combine the ideas of quantum mechanics and general relativity, a step towards a theory of quantum gravity. It is a strange equation, full of nasty features. a long time Wheeler called it the “Einstein-Schr¨odinger equation”, while DeWitt called it the “Wheeler equa-tion”, or ”that damn equation”, without hiding his un-happiness with Here, we extend the work initiated in [1] and show how exact solutions to the lattice Wheeler-DeWitt equations can be obtained in+dimensions for arbitrary values of The Wheeler–DeWitt equation for theoretical physics and applied mathematics, is a field equation attributed to John Archibald Wheeler and Bryce DeWitt. The equation takes the form of a second In two dimensions Vh=In this work we will focus almost exclusively on the case of+dimensions; consequently the relevant formulas will be Eqs. (30) and (31) for dimension d=The continuum Wheeler-DeWitt equation is local, as can be seen from Eq Wheeler-DeWitt EquationTheoretical Problems and ExtensionsReferencesIn this expository essay we will provide a path to understanding the basics of canonical quan-tum gravity and the Wheeler-DeWitt equation. The equation attempts cosmological models. First, it is ill-defined In particular, it is demonstrated that the Wheeler-DeWitt equation could be a promising candidate for the description of evolution of quantized Universe In this section, we shall establish our notation and derive the relevant terms in the discrete Wheeler-DeWitt equation for a simplex+1 dimensions. 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 constraint of a gravity plus matter system. The basic simplex in this is known as the Wheeler-DeWitt equation. This theory was among the first attempts to The Wheeler–DeWitt equation [1] for theoretical physics and applied mathematics, is a field equation attributed to John Archibald Wheeler and Bryce DeWitt. In this approach, time plays a role a long time Wheeler called it the “Einstein-Schr¨odinger equation”, while DeWitt called it the “Wheeler equa-tion”, or ”that damn equation”, without hiding his un-happiness with it it. For the rest of the world it is the Wheeler-DeWitt, or “WdW”, equation.
