The universe appears to be expanding, and the expansion is accelerating at different rates when measured by different methods. Looking at the cosmic microwave background (CMB) gives a value of around 68 km/s per megaparsec for the Hubble constant, whereas Type 1A supernovas (SN1A) yield a value of around 74 km/s per megaparsec. That is, the acceleration of the expansion of the cosmos increased by about 9% over 4 or 5 billion years. Given the time difference, a binary choice seems natural: Is there something about the data reaching us from different epochs or the space they traversed that skews the answers, or has dark energy gotten stronger over time? A third option is to make the passage of time itself an explicit factor in the measurement of distance. If there are physical effects that depend on the amount of time that an object has existed in a given place, the rate of apparent expansion might be equalized across all epochs. The specific proposal being made here is that spacetime should not be exempted from physical laws like inertia, conservation, and E=mc^2. In turn, imaginary constructs like gravity wells should have real physical effects, beyond gravitation, that manifest by means of spacetime's actions.
