The temperature of heaven can be rather accurately computed. Our authority is the Bible, Isaiah 30:26 reads, Moreover, the light of the moon shall be as the light of the sun and the light of the sun shall be sevenfold as the light of seven days. Thus, heaven receives from the moon as much radiation as the earth does from the sun, and in addition seven times seven (forty nine) times as much as the earth does from the sun, or fifty times in all. The light we receive from the moon is one ten-thousandth of the light we receive from the sun, so we can ignore that. With these data we can compute the temperature of heaven: The radiation falling on heaven will heat it to the point where the heat lost by radiation is just equal to the heat received by radiation. In other words, heaven loses fifty times as much heat as the earth by radiation. Using the Stefan-Boltzmann fourth power law for radiation
(H/E)4 = 50
where E is the absolute temperature of the earth, 300°K (273+27). This gives H
