Thanks to esquire.com (and their source, applied optics), I’ve acquired some new knowledge today:
Revelations 21:8 calls hell a “lake which burneth of fire and brimstone.” To maintain liquid (lake) form and not vapor (cloud), molten brimstone or sulfur must be ≤ sulfur’s boiling point (444.6°c).
Isaiah 30:26 says heaven receives from the moon as much radiation as Earth from the Sun, plus “sevenfold as the light of 7 days.” The Stefan-Boltzmann 4th power law for radiation (H/E)4 = 50, where E is the absolute temperature of Earth (300°k), deems Heaven 798°k or 525°c.
Heaven is hotter than hell.
