Thoughts on the raqîa‘ and a Possible Explanation for the Cosmic Microwave Background. The Cosmic Microwave Background (or “CMB” for short) is radiation from around 400,000 years after the start of the Universe. It is an important source of data on the early universe because it is the oldest electromagnetic radiation in the universe, dating to the epoch of recombination. The discovery of cosmic microwave background radiation is one of the strongest pieces of evidence supporting the “Big Bang” theory of the origin of the universe. Cosmology also offers a unique means of searching for new physics through the effect on the CMB of relic particles from the early Universe, including sterile neutrinos, light bosons, and other new particle species. Discovered in 1965, the CMB is the relic radiation left over today from an early hot phase of the universe (often referred to informally as the ​“Big Bang”). Research; Cosmic Microwave Background; CMB. The recent discovery of the previously predicted acoustic peaks in the power spectrum has established a working cosmological model: a critical density universe consisting of mainly dark matter and dark energy, which formed its structure through gravitational instability from quantum fluctuations during an inflationary epoch.
