Our Earth [ http://antwrp.gsfc.…] is not at rest. The Earth moves around the Sun [ http://antwrp.gsfc.…]. The Sun orbits the center of the Milky Way Galaxy [ http://antwrp.gsfc.…]. The Milky Way Galaxy orbits in the Local Group of Galaxies [ http://www.seds.org…]. The Local Group falls toward the Virgo Cluster of Galaxies [ http://antwrp.gsfc.…]. But these speeds are less than the speed that all of these objects together move relative to the cosmic microwave background [ http://spectrum.lbl…] (CMB). In the above all-sky map [ http://space.gsfc.n…], radiation in the Earth's direction of motion appears blueshifted [ http://imagine.gsfc…] and hence hotter, while radiation on the opposite side of the sky is redshifted [ http://www.space.co…] and colder. The map [ http://map.gsfc.nas…] indicates that the Local Group [ http://www-hpcc.ast…] moves at about 600 kilometers per second relative to this primordial radiation [ http://www.nap.edu/…]. This high speed was initially unexpected and its magnitude is still unexplained. Why are we moving so fast? [ http://zebu.uoregon…] What is out there? [ http://antwrp.gsfc.…]
