| dc.description | We point out that the recent WMAP findings of a suppressed large scale power in the Cosmic Microwave Background anisotropy power spectrum, if of cosmological origin, make the case for a new cosmic coincidence problem.The observed suppression of anisotropies at large angles requires an explanation for why this suppression is occuring {\it only} for perturbation wavelengths of the order of our present Hubble horizon. This is a very challenging task since a consistent model for the emerging picture of the universe has to address any cosmic coincidence and thus may reveal a deeper inter-relation with the dark energy problem. | |
