Description

We show that Dark Matter consisting of ultralight bosons in a Bose-Einstein condensate induces, via its quantum potential, a small positive cosmological constant which matches the observed value. This explains its origin and why the densities of Dark Matter and Dark Energy are approximately equal. References: S.Das, R. K. Bhaduri, arXiv:1808.10505, arXiv:1812.07647
