196 ARTIFICIAL INTELLIGENCE<br />

Ironically, this catastrophic view of planetary dynamics is more<br />

biblical than classically scientific. For many years, scientists<br />

avoided using catastrophes to explain events, since they were hard<br />

to reproduce, difficult to analyze statistically, <strong>and</strong> smacked of biblical<br />

events. In the end, though, science learned that catastrophes<br />

do happen, which is its strength. When presented with evidence<br />

contrary to the theory, science learns <strong>and</strong> grows.<br />

All 63 moons in the solar system should orbit their planets in the<br />

same sense, but at least six have backward orbits. Furthermore,<br />

Jupiter, Saturn, <strong>and</strong> Neptune have moons orbiting in both directions.<br />

This one is really easy to explain. Some of the moons of the<br />

planets formed at the same time as the planets <strong>and</strong> orbit their parent<br />

bodies in the “correct” sense, that is, in the same direction that<br />

the planet spins <strong>and</strong> orbits the Sun. However, it’s possible, although<br />

generally not easy, for a planet to capture moon-sized objects. If<br />

the conditions are just right, it’s not only possible but rather common<br />

that such a captured moon would orbit the planet in the<br />

opposite direction. Jupiter <strong>and</strong> Saturn both have moons that orbit<br />

backwards, or retrograde. All of these moons orbit at large distances<br />

<strong>from</strong> their planet, as is expected in a capture event as well.<br />

Again, using this as a creationist argument is disingenuous on<br />

their part. Retrograde moons have been known about <strong>and</strong> explained<br />

for many decades.<br />

The sun turns the slowest, the planets the next slowest, <strong>and</strong> the<br />

moons the fastest. But according to evolutionary theories, the<br />

opposite should be true. The sun should have 700 times more<br />

angular momentum than all the planets combined. Instead, the<br />

planets have 50 times more angular momentum than the sun.<br />

The sun has 99.9% of the total mass of the solar system, but<br />

99% of the total angular momentum is concentrated in the larger<br />

planets.<br />

According to the cloud-collapse theory, the Sun should indeed<br />

be spinning faster than any solar-system body. When a figure skater<br />

draws in her arms during a spin, she spins faster <strong>and</strong> faster. The
