Abstract
In this short article the author makes the case that Dewey Larson's assertion of space and time as fundamentally quantized is an equal contribution to his much better known "motion as the sole constituent of the physical universe." In addition, the phenomena of boundary crossing, required by all quantum concepts, is shown to be a process of much under-appreciated complexity and importance. Finally the author speculates that crossing the quantum boundary may be a phenomena of the "Astral Plane."
