a . “ [The following is] a somewhat surprising outcome considering the size of the Moon and the assumption that most of its heat energy had been lost. ... These unexpectedly high lunar [heat flow] values seem to indicate the Moon’s interior is much hotter than most thermal models had anticipated. If the temperature gradient in the lower regolith is extrapolated to great depths, the lunar interior would appear to be at least partly molten—a condition contradicted by other evidence.” Nicholas M. Short, Planetary Geology (Englewood Cliffs, New Jersey: Prentice-Hall, 1975), p. 184.
u In 2011, the Moon was discovered to have a small liquid core. [See Renee C. Weber et al., “Seismic Detection of the Lunar Core,” Science, Vol. 331, 21 January 2011, pp. 309–312.]
u “ Actual values of heat flow determined on the Moon at the Apollo 15 and 17 sites were two and three times higher than had been predicted.” Short, p.183.
b . Dr. Kent Davey developed a 40,000 finite element model that considered a body of water 1/2 mile thick at temperature 150°F only 1/2 mile below the Moon’s surface. After 10,000 years that water’s temperature would only have decreased 53°F. Kent Davey, personal communication, 9 November 2015.
c . The unexpectedly large heat flow may be a consequence of large impacts occurring on the lunar surface soon after the global flood. Because the flood was recent (only about 5300 years ago) excess heat should still be present. [See "When Was the Flood, the Exodus, and Creation?" on page 485, Figure 175 on page 311 and "Did the Preflood Earth Have a 30-Day Lunar Month?" on page 327.]
