/ The temperature of Heaven can be rather \
| accurately computed from available      |
| data. Our authority is Isaiah 30:26,    |
| "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 we do from the Sun, and in |
| addition seven times seven (49) 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, i.e., Heaven loses fifty     |
| times as much heat as the Earth by      |
| radiation. Using the Stefan-Boltzmann   |
| law for radiation, (H/E)^4 = 50, where  |
| E is the absolute temperature of the    |
| earth (~300K), gives H as 798K (525C).  |
| The exact temperature of Hell cannot be |
| computed, but it must be less than      |
| 444.6C, the temperature at which        |
| brimstone or sulphur changes from a     |
| liquid to a gas. Revelations 21:8 says  |
| "But the fearful, and unbelieving ...   |
| shall have their part in the lake which |
| burneth with fire and brimstone." A     |
| lake of molten brimstone means that its |
| temperature must be at or below the     |
| boiling point, or 444.6C (Above this    |
| point it would be a vapor, not a lake.) |
| We have, then, that Heaven, at 525C is  |
| hotter than Hell at 445C.               |
|                                         |
