Relativity and Cosmology


Ever-Present Lambda and the Quantum Potential of Spacetime

Authors: Willard Mittelman

An approach to dark energy is presented that combines ideas of causal set theory with a Machian perspective and a treatment of spacetime as a condensate, yielding a "quantum potential of spacetime" Q whose density ρQ acts as an effective Λ that satisfies the uncertainty relation ΔVΔΛ ~ 1 of unimodular relativity. In contrast to the ever-present Λ of causal set theory, ρQ's value is always non-negative, and the nonlocality of Q ensures that ρQ is spatially homogeneous, in accordance with observation.
