Explanation: Our Earth is not at rest. The Earth moves around the Sun. The Sun orbits the center of the Milky Way Galaxy. The Milky Way Galaxy orbits in the Local Group of Galaxies. The Local Group falls toward the Virgo Cluster of Galaxies. But these speeds are less than the speed that all of these objects together move relative to the cosmic microwave background radiation (CMBR). In the above all-sky map from the COBE satellite, radiation in the Earth's direction of motion appears blueshifted and hence hotter, while radiation on the opposite side of the sky is redshifted and colder. The map indicates that the Local Group moves at about 600 kilometers per second relative to this primordial radiation. This high speed was initially unexpected and its magnitude is still unexplained. Why are we moving so fast? What is out there?
grooovy
The truth is out there.
A lot more is going on here. Astronomy magazine for December had an article I think is on this topic. Dipole anisotropy is only the lowest order. It gets worse in octupoles. The microwave background might be a local phenomenon.
ying yang
red top is global warming, lower blue is global cooling, you lose Al Gore now hand back all the monies you made on this scam convicing the mentaly challenged that we are killing the earth
Who would of though we live in a “tie-died” universe? Oh dude.
That tao thingy might indeed be a map of the entire heavens. Who knows, maybe they knew about this thousands of years ago.
