Hot Planets
Jupiter, Saturn, and Neptune each radiate away more than twice the heat energy they receive from the Sun (a). Uranus (b) and Venus (c) also radiate too much heat. Calculations show that it is very unlikely that this energy comes from nuclear fusion (d), radioactive decay, gravitational contraction, or phase changes (e) within those planets. This suggests that these planets have not existed long enough to cool off (f).

d. To initiate nuclear fusion, a body must be at least ten times as massive as Jupiter. [See Andrew P. Ingersoll, “Jupiter and Saturn,” Scientific American, Vol. 245, December 1981, p. 92.]
e. Ingersoll and others once proposed that Saturn and Jupiter could generate internal heat if their helium gas liquefied or their liquid hydrogen solidified. Neither is possible, because each planet’s temperature greatly exceeds the critical temperatures of helium and hydrogen. (The critical temperature of a particular gas is that temperature above which no amount of pressure can squeeze it into a liquid or solid.) Even if the temperature were cold enough to permit gases to liquefy, what could initiate nucleation? When I mentioned this in a private conversation with Ingersoll in December 1981, he quickly acknowledged his error.

Jupiter would have rapidly cooled to its present temperature, even if it had been an unreasonably hot 20,000 kelvins when it formed. Evolutionary models require too much time. [See Edwin V. Bishop and Wendell C. DeMarcus, “Thermal Histories of Jupiter Models,” Icarus, Vol. 12, May 1970, pp. 317–330.]
For the last 150 years, the age of the Earth, as assumed by evolutionists, has been doubling at roughly a rate of once every 15 years. In fact, since 1900 this age has multiplied by a factor of 100!
Actually, most dating techniques indicate that the Earth and solar system are young—possibly less than 10,000 years old.
