Description

We discuss possible signs for early quintessence in the light of the high precision spectrum of CMB anisotropies from WMAP. Early quintessence would have interesting consequences for our understanding of the dynamics of dark energy and the fate of the cosmological constant. We also address the new macroscopic fundamental interaction that would be mediated by the cosmon field and its implication for the time variation of fundamental "constants".
