    The structures in maps of the cosmic microwave background created from balloon/ground/satellite data are images of sound a few hundred thousand years after the Big Bang, when light decoupled from matter, and also of the rippled gravitational patterns on our past light cone. The two vintage figures below are from the Boomerang long duration balloon experiment's "B98 map" of the first & second acoustic peaks of 2000/2001 heralding the high precision era in CMBology which we have been very much engaged in a series of projects up to now, and in to the future.


  

    The vintage figures have been considerably improved with maps from Boomerang 2002, 2003 & 2006 (B03 polarization, and third peak), from the Chile-based Cosmic Background Imager 2002,04a,b,05, 08 (polarization, fourth and fifth peaks and the damping tail), from the South-Pole-based ACBAR 2002, 2006, 2008 (damping tail), the L2-based satellite WMAP 2003, 2006, 2008, 2012 data (large scales and the first, second and third peak), the Atacama Cosmology Telescope 2009, 2010, 2011, 2013, 2016 (third to seventh peaks), and the Planck satellite (2013 & 2015, shown in Figures 3, 4).
From this information we determine the mass-energy density of baryons (the ordinary matter that makes up stars and humans); of the dark matter (that clusters in galaxy halos);  of curvature that warps space (nearly zero, i.e., a nearly flat U on average);  and, when combined with large scale clustering observations pre-WMAP Boomerang/Maxima 2001 in Figure 2), of the "dark energy" of the vacuum that seems to dominate the Universe - definitely not Einstein's blunder; now DE evidence from CMB alone, using graviational lensing of the CMB from Planck 2015 (Figure 3).

We also learn of  the tiny patterns of quantum noise generated in the ultra early universe  that  grow into the structures of that bit of the Universe within our cosmic horizon that we can observe - the galaxies, their clusters and superclusters, the stars and planets, and us, Pythagoreans all, knowing this harmony is to be understood with mathematics. Fig.4 is the Planck 2015 map of temperature, which reveals the Pythagorean simplicity. Oruborus: our cosmic consciousness.
