Originally theorized in the early twentieth century, blackbodies are invisible to human instruments. Science describes them as being perfect absorbers and emitters of energy.
A blackbody is a theoretical device, so Science invented a theoretical property called emissivity.
Blackbody
A hypothetical entity which absorbs all energy, reflects none and emits
energy with perfect efficiency. A blackbody is assumed to satisfy
the following ideal conditions;
A blackbody absorbs all incident radiation regardless of wavelength and direction.
For a prescribed temperature and wavelength, no surface can emit more energy than a blackbody.
Although the radiation emitted by a blackbody is a function of wavelength, it is independent of direction. A blackbody is defined as a diffuse emitter.
Emissivity
The ratio of emittance of a given object and a theoretical blackbody at the same temperature. The emissivity of a theoretical blackbody is defined as 1.0 and that of a perfect reflector as 0.
(Thus emissivity = 1.0 - reflectivity.)
When Human Science measures energy, it is limited to measuring differences, fluctuations in the strength, direction, etc. So, stating that blackbodies are perfect emitters and absorbers of energy is a fancy way of saying we can't see them. This does, however, lead to an inevitable conclusion: If we can't see them, blackbodies never get measured, and so remain in perpetually undetermined state.
