Quantum Theory is embodied by the Heisenberg Uncertainty Principle (HUP) which states that there is a natural limitation in the measurement of certain paired quantities. Perhaps the most direct explanation for this limitation is that uncertainty is caused by changes in the quantities themselves as the Universe evolves. This short paper references a solution to Einstein`s field equations that forms the basis for a cosmology in which the base quantities of space, time and energy (mass) change monotonically in an opposing manner parameterized by the expansion ($a$).[1} Each instance of $a$ would therefore be defined by its own unique inertial frame. The author postulates just such a possibility and then utilizes the HUP relationship to determine if an identifiable number appears mathematically. In this case a relatively straight forward calculation produces a number within a few percentage points of the empirically derived $h$.
