Can someone please explain the nebular theory to me?
NEBULAR THEORY A great cloud of gas and dust is called nebula. This cloud collapsed due to gravity, then it begins to spin faster because of the angular momentum conservation. Because of the competing forces associated with gravity, gas flatten into spinning pancake shape with a bulge last the center. As the nebula collapses further, instabling could cause local regions to conduct gravitational. These local regions of condensation will become the sun and the planets, as well as their moons and other debris in the solar system.
