We discussed in class the idea of pair creation (creation of a particle and its anti- particle from two photons) in the early universe. Assume that the photons have on average an energy of 2.7 kT, where k is the Boltzmann constant and T is the temperature of the Universe. What is the lowest temperature in which pair creation can produce a proton and anti-proton ? How about an electron and anti-electron ?
