The nebular hypothesis of the formation of the solar system assumes that the material that became the solar system began as a large spherical cloud of gas and dust, rotating slowly. As the solar system formed, most of this material was transformed into a compact, flattened disk, rotating more rapidly. What is the explanation for this change in shape and rate of rotation?
Then What process heated the early solar nebula as it slowly condensed toward a central protosun? I. e. why was the temperature rising in the center of the contracting nebula?
