Abstract

For the first time in human thought it is now possible to observationally  determine how much matter is in the Universe as a whole. These observations - pending the results to be announced Mar 21 from the Planck satellite - strongly support the "Concordance Model" of Hot Big Bang Cosmology, and reinforce earlier indications that ordinary matter (atoms, nuclei and electrons) make up at present at most 4% of the total of the Universal energy density. The big surprise was that the rest consists of *two* kinds of unknown forms of matter: the so-called Dark Matter and Dark Energy. I will summarize for non-specialists the various lines of evidence for their existence, and some of the theoretical ideas which have been proposed to account for their properties.
