The apparent contradiction of the thermodynamically smooth CMBR temperature, a highly entropic state achieved long before the moment of decoupling at 380,000 years after the big bang, is reconciled with the Second Law by comparing it to the exceedingly vaster entropy of today's universe, filled with black holes.
The existence of this preferred frame is implied by the wave analysis and its observability provides the essential empirical basis for asserting at last that objective simultaneity coincides with the Einstein simultaneity of observers at rest in the CMBR frame.
CMBR is the leftover relic radiation from the Big Bang event that kickstarted the formation of our universe.
It starts with the fluctuations in the density of the universe seen in the CMBR, then models the way that matter collapses into today's galaxies over the subsequent 13 billion years.
The data release of the CMBR - in essence a map of the Big Bang - is also scheduled for 2012.
The CMBR is 1,000 times cooler today, corresponding to a black body radiation temperature of approximately 3 [degrees] K.
The continuous fluctuation of energy in the quantum field which are believed to be responsible for tiny variations of temperature in the CMBR provided the 'seeds' from which stars and galaxies were formed.
Since the 1960s, radio astronomers have known that the CMBR bathes Earth from all directions.
The cosmic microwave background ration (CMBR) is linearly polarized and as such must have undergone Thomson scattering.
This is the 'cosmic microwave background radiation' (CMBR).
In the first decade of the twenty-first century, some remarkable measurements on the fine structure of cosmic microwave background radiation (CMBR) found acoustic peaks in this "surface of last scattering." According to the current theory, about 370,000 years after the Big Bang, the primordial plasma soup of photons, baryons, and electrons had cooled to a temperature of 3000 degrees Kelvin, at which point the equilibrium shifted to the formation of neutral hydrogen atoms.
