1 hour ago · The structures, which were established in the very early universe, have imprinted themselves on the cosmic microwave background. The fine patterns, tiny disturbances on an otherwise homogeneous surface, provide us with a wealth of information about the state of the early universe, its development, and its current geometry.
Relation between the wavelength of the black-body radiation curve peak and the temperature
In physics, Wien's displacement law states that the black-body radiation curve for different temperatures will peak at different wavelengths that are inversely proportional to the temperature. The shift of that peak is a direct consequence of the Planck radiation law, which describes the spectral brightness or intensity of black-body radiation as a function of wavelength at any given temperature.
