WebApr 7, 2024 · These sensors are calibrated using a traditional two-point approach, with one source typically a free-space blackbody target and the second a clear view to the cosmic microwave background ... WebA blackbody is an object that absorbs all of the electromagnetic radiation going at it. Since nothing is reflected or passes through, a blackbody often appears "dark" to the naked eye. However, a blackbody is always emitting a spectrum that turns out is extremely temperature dependent. WebDec 26, 2024 · From Brent Follin's Quora answer to How is Hubble constant calculated from Cosmic Microwave Background Radiation measurements? The redshift is known quite precisely from the theory, since a hot big bang model (the standard model of cosmology) predicts the point at which the plasma de-ionized to form neutral hydrogen. ciao octopusenergy.it
