Solar Nebula Hypothesis Ready for History’s Dustbin? | Space News

All popular theories about the origins of objects in our solar system are based on the solar nebula hypothesis. First proposed in the mid-18th century by the Swedish mystic Emmanuel Swedenborg, the hypothesis proposes that four and a half billion years ago, a primordial cloud called a nebula collapsed gravitationally, forming the Sun and a flat disk, and it was from that disk that our Earth and all of the planets formed. The “competing” theoretical processes that created these bodies are purely gravitational, meaning collisions and accretion over eons of time.

As we’ve documented exhaustively on this series, no number of failed scientific predictions based on this story have yet forced any real reassessment of its tenability. In this episode, we explore the sound theoretical alternatives that the Electric Universe and Plasma Cosmology offer.
