In the nebular hypothesis proposed by Pierre-Simon Laplace, after the formation of the sun, he suggested that the sun rotated more quickly. This is due to the conservation of angular momentum as the material in the solar nebula collapsed under gravity and formed the sun, resulting in an increase in its rotational speed.
