The microwave radiation coming from all directions that is believed to be the red-shifted glow of the Big Bang.
The primordial radiation field that fills the universe. It was created in the form of gamma rays at the time of the big bang, but has since cooled so that today its temperature is 3 K and its peak wavelength is near 1.1 millimeters (in the microwave portion of the spectrum). Also known as the 3-degree background radiation. Also called cosmic microwave background radiation, CMBR.
This is the radiation left behind by the Big Bang. Its detectable today as radio-wavelength radiation, for example in the COBE map of the entire night sky.
An isotropic microwave radiation thought to be the remnant of the big bang; the radiation has a blackbody spectrum at a temperature of 3oK.
(cosmology) the cooled remnant of the hot big bang that fills the entire universe and can be observed today with an average temperature of about 2.725 kelvin
radiation of the cosmos left over from the Big Bang.
The background radiation everywhere in the universe, mostly in the frequency range 3 × 108 to 3 × 1011 Hz, discovered in 1965. It is believed to be the cosmologically redshifted radiation released by the Big Bang itself. Also known as the primal glow.
The remnant radiation from the Big Bang. Its distribution in the universe today can tell us about how the universe may have formed.
Cosmic Background Radiation (abbreviated CMB, CMBR and CBR) is the radiation (energy) which remains from the original Big Bang explosion which formed the universe. This radiation has cooled as the universe has expanded and is now slightly less than 3 degrees above absolute zero.
an electromagnetic radiation, diffused and almost even, that comes from all directions, and that permeates the whole Universe. It has a maximum of intensity at the wavelength of 2.6 cm and, it is thought, is what remains of the radiation emitted during the Big Bang, the massive explosion that originated the Universe according to the modern cosmological theories. It is called "3 K radiation" because its wavelength corresponds to that emitted by a black body at the temperature of 3 K, that is -270 degrees centigrades.
An electromagnetic radiation field at a black body temperature of 2.7 Kelvin that fills the entire universe uniformly to 0.00001 Kelvin. Also known as the Cosmic Microwave Background (CMB), it is thought to be the residual glow from the very hot early universe that followed the Big Bang.
A weak, electromagnetic (mostly radio) signal that permeates all of space, thought to be relic radiation of the big bang.
