What is the force that keeps the star from blowing apart?

It is true that within most stars there are violent hydrogen fusion reactions churning away, but these do not cause the supernova. Stars are so large that the gravitational forces holding them together are strong enough to keep the nuclear reactions from blowing them apart.

What does a collapsing cloud do as it shrinks?

Why did the solar nebula heat up as it collapsed? As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal energy. However, as shown in the video, the nebular theory predicts that a cloud will rotate rapidly once it shrinks to a small size.

Why does a cloud collapse rapidly at first and then slow down as it gets denser?

6) Why does a cloud collapse rapidly at first, and then slow down as the it gets denser? Answer: The self-gravity causes the cloud to collapse. Gravitational potential energy is turned to heat (through friction) and released as infrared light from the cloud.

What makes the nebula collapse?

Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.

What two things started Earth?

When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.

What do you think is the difference between the terrestrial and jovian planets?

The main atmosphere of terrestrial planets is a gaseous mix of carbon dioxide and nitrogen gases, and all terrestrial planets have rocky surfaces. Jovian planets are larger, further from the sun, rotate faster, have more moons, have more rings, are less dense overall and have denser cores than terrestrial planets.
