Webnebular hypothesis n. A hypothesis concerning the formation of stars and planets, and therefore the origin of the solar system, according to which a rotating nebula underwent gravitational collapse into a star with an accretion disk, from which planets condensed or formed by coagulation of dust particles into increasingly larger bodies. WebThe nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud, most likely at the edge of a Wolf-Rayet bubble. The …

This theory proposes that our sun and its planets were formed 4. 6 billion years ago when a cloud of interstellar gas and dust (the solar nebula) began to contract due to gravity.
The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets. … See more There is evidence that Emanuel Swedenborg first proposed parts of the nebular theory in 1734.
