		where \Delta\lambda is the displacement of the electrodynamic waves that are dependent on the distance and the constant k in both the macro physics cosmological redshift that is misinterpreted by Hubble as H, and the fractional difference in micro physics that is misinterpreted by Planck as quantum shift h.
		The fractional displacement or difference between the wave-units that I have derived is the same constant k = h = H. This heat radiation entropy displacement \Delta\lambda is dependent on the emitted wavelengths and the covered distances.
		In the end the entropy displacement has elonged the wavelengths until they reaches the wavelengths in the supraleading temperature of the space that is the cosmic radiation's background and the end of the displacement that cause the cosmic horizon for us.

		Wien's displacement law states that the hotter an object is, the shorter the wavelength at which it will emit most of its radiation, and further that the frequency for maximal or peak radiation power is found by dividing Wien's constant by the temperature in Kelvins.
		The surface temperature of the Sun is 5778 K. Using Wien's law, this temperature corresponds to a peak emission at a wavelength of 2.89777 million nm K/ 5778 K = 502 nm = about 5000 Å.
		Because the spectrum resulting from Planck's law of fl body radiation takes a different shape in the frequency domain from that of the wavelength domain, the frequency location of the peak emission does not correspond to the peak wavelength using the simple relationship between frequency, wavelength, and the speed of light.

		(C) Kirchhoff's Law: The radiation law which states that at a given temperature the ratio of the emissivity to the absorptivity for a given wave- length is the same for all bodies and is equal to the emissivity of an ideal flbody at that temperature and wavelength.
		(B) Planck's Law: An expression for the variation of monochromatic emittance (emissive power) as a function of wavelength of flbody radiation at a given temperature; it is the most fundamen- tal of the radiation laws.
