Planck time limitations to cosmogony

Planck time (10⁻⁴³s) is the time it would take a photon traveling at the speed of light to cross a distance equal to the Planck length (1.616252×10⁻³⁵ meters). It has been proposed that this may be the hypothetical "quantum of time", the smallest measurement of time that has any meaning, although in current physics theory time is not quantized.

Although the laws of physics lose experimental support at the Planck time, modern science has sought to clarify the nature of these paradoxes, so far with only limited success. For example, one can apply the current understanding of grand unified theories (GUTs) – both quasi-classical (such as general relativity) and modern (such as quantum gravity, superstring, and M-theories) – to these three primary cosmogonic paradoxes in thought experiments. While these result in some contradictions and lack completeness in a mathematical sense (being based on axioms that are 'merely' self-evident, but not robust under the stresses of radical scepticism) these paradoxes can nonetheless be analyzed rationally using the subatomic applications of quantum cosmology, particularly through the employment of the Schrödinger wave equations.

In each case, where general relativity fails as the curvature of space-time invokes singularities from its equations at t=0, the statistically "grey" nature of quantum cosmology tends to allow a scientific rationale to account for each paradox, and in so doing allows for a scientific perspective on previously theistic terrain. For example, application of quantum "fuzziness" (per the Wheeler-DeWitt application of subatomic position and momentum equations to universal radius and expansion) avoids boundary issues, as developed in the Hartle-Hawking Wave Function.

All such equations are based on differentials, which assume a continuum, where in our universe, affected by the Planck length and other minimum scales, this continuum has only limited meaning, about which philosophy remains in a state of semantic flux.
