The core concept of this paper is the relation between an accelerating field and time uncertainty. This relation distills from the derivation of Newton's Law of Gravitation via the uncertainty principle. It's shown, further, that this relation can be used to derive the Coulomb Force, suggesting that it may be a general principle in nature. Taking this concept further, this paper draws a connection between expanding space and acceleration---offering an explanation for the missing-mass problem in galaxies. The paper goes on to draw a connection between the expansion of space and time uncertainty, leading to a startling conclusion: The expansion of space is not a function of the energy contained therein, but conversely, the mass of the universe is created in concert with the expansion of space. Further, because this expansion is a function of time, the mass of the universe is a function of time and increases in lockstep therewith. It's deemed that the model of the universe presented herein obviates the need for dark matter and dark energy to explain our observations of the cosmos.
