Question:

The peak intensity of the CMBR occurs at a wavelength of 1.1 mm.

(a) What is the energy in eV of a 1.1-mm photon?

(b) There are approximately 10⁹ photons for each massive particle in deep space. Calculate the energy of 10⁹ such photons.

(c) If the average massive particle in space has a mass half that of a proton, what energy would be created by converting its mass to energy?

(d) Does this imply that space is "matter dominated"? Explain briefly.
