15. Given that the cosmic background radiation has the spectrum of a black body throughout the evolution of the Universe, determine how its temperature changes with redshift $z$. In particular, give the temperature of the background radiation at the epoch $z\approx 10$ (that of the farthest currently observed objects). The current temperature of the cosmic background radiation is $2.73\ \mathrm{K}$ .
