Abstract
Motivated by the problem of obtaining a plausible account of dark energy, we describe the microstructure of spacetime as continually fluctuating between discreteness and a generally continuous state, with dark energy taking the form of a quantum potential of spacetime that emerges from this process of fluctuation. In addition, we consider the problem of explaining the initial conditions of our universe, which leads us to entertain the idea that spacetime itself is a superposition of both discrete and continuous metrics.
