| In the Nebular Hypothesis, a cloud of gas and dust collapsed by gravity begins to spin faster because of angular momentum conservation | |

| The collapsing, spinning nebula begins to flatten into a rotating pancake called accretion disk |
 |
| As the nebula collapses further, local regions begin to contract gravitationally on their own because of instabilities in the collapsing, rotating cloud. This process is called fragmentation of accretion disk |
