Nebular Hypothesis, Book Reviews

A major critique came during the 19th century from who maintained that could not allow condensation of material. It was also rejected by astronomer who stated that "those who believe in the Nebular Theory consider it as certain that our Earth derived its solid matter and its atmosphere from a ring thrown from the Solar atmosphere, which afterwards contracted into a solid terraqueous sphere, from which the Moon was thrown off by the same process." He argued that under such view, "the Moon must necessarily have carried off water and air from the watery and aerial parts of the Earth and must have an atmosphere." Brewster claimed that 's religious beliefs had previously considered nebular ideas as tending to atheism, and quoted him saying that "the growth of new systems out of old ones, without the mediation of a Divine power, seemed to him apparently absurd."

Giant planets can significantly influence formation. The presence of giants tends to increase and (see ) of planetesimals and embryos in the terrestrial planet region (inside 4 AU in the Solar System). If giant planets form too early, they can slow or prevent inner planet accretion. If they form near the end of the oligarchic stage, as is thought to have happened in the Solar System, they will influence the merges of planetary embryos, making them more violent. As a result, the number of terrestrial planets will decrease and they will be more massive. In addition, the size of the system will shrink, because terrestrial planets will form closer to the central star. The influence of giant planets in the Solar System, particularly that of , is thought to have been limited because they are relatively remote from the terrestrial planets.

The Formation of the Solar System

The region of a planetary system adjacent to the giant planets will be influenced in a different way. In such a region, eccentricities of embryos may become so large that the embryos pass close to a giant planet, which may cause them to be ejected from the system. If all embryos are removed, then no planets will form in this region. An additional consequence is that a huge number of small planetesimals will remain, because giant planets are incapable of clearing them all out without the help of embryos. The total mass of remaining planetesimals will be small, because cumulative action of the embryos before their ejection and giant planets is still strong enough to remove 99% of the small bodies. Such a region will eventually evolve into an , which is a full analog of the asteroid belt in the Solar System, located from 2 to 4 AU from the Sun.

What Your Textbook Says about the Origin of the Solar System

In reconsidering the creation of the earth, the solar systemand the rest of the vast universe a good place to begin is toreflect in awe with the Psalmist of old who penned this wordsas inspired by the Holy Spirit:

that was the supposed origin of our solar system.

Catastrophes affecting the creation evidently occurred sometime after the end of creation week---but not before because ofthe statement of Genesis 1:31---the older "gap theory"proposing a catastrophe between Gen. 1:1 and 1:2 has been wellrefuted by Hebrew scholars in recent years. Disasters affectingthe solar system could have occurred in connection with the fallof the angels, or could be related somehow to the fall of manand the resultant "curse" on the earth. The Second Lawof Thermodynamics and radioactive decay were probably not operativein the universe until after the fall. The angels have a role inthe government of nature (Heb. 2:5), so the fall of one thirdof God's angels may have had major consequences in the way naturehas operated ever since. See
