81% Informative

The appearance of microscopic objects with distinct topologies and different Euler characteristics, such as instantons and wormholes, at the spacetime-foam level in Euclidean quantum gravity approaches leads to spacetime topology changes.

Since the latter in a dynamical spacetime is in general time-dependent, one obtains an effective dark energy sector of topological origin.
