WebA black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The name "black body" is given because it absorbs all colors of light. A black body also emits black-body radiation. In contrast, a white body is one with a "rough surface that reflects all ... http://www.bigbangcentral.com/microwave_page.html
Blackbody Radiation
WebThe CMB Black Body Spectrum as Measured by COBE The term black body refers to any object that is a perfect absorber of electromagnetic radiation (in other words, light). While no electromagnetic radiation passes through or is reflected from a black body, theory predicts that the body will emit radiation at all possible wavelengths. ... WebTools. CMB spectral distortions are tiny departures of the average cosmic microwave background (CMB) frequency spectrum from the predictions given by a perfect black body. They can be produced by a number of standard and non-standard processes occurring at the early stages of cosmic history, and therefore allow us to probe the standard picture ... binary brother definition
