The '''nebula hypothesis''' (alternately, '''nebular hypothesis''') is a [[Big Bang]] theory model of the formation of a [[solar system]]. It theorizes that a solar system begins as a rotating cloud of [[gas]] and [[dust]] that contracts to create a flat disk with a [[star]] at its center. [[Planet]]s grow from the [[particle]]s surrounding the star, creating a solar system.
