TEMPERATURE OF HEAVEN
The temperature of Heaven can rather be accurately computed. 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, 7X7 (49) times as much as the Earth does from the Sun or 50 times in
all. The light we receive from the Moon is 1/10,000 of the light we receive from
the Sun, so we can ignore that... 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 50 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...[However] 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 it's temperature
must be at or below the boiling point, 444.6C. We then have that Heaven, at 525C
is hotter than Hell at 445C.
