Solar Nebular Hypothesis The idea behind the Solar Nebular Hypothesis is that the solar system was condensed from an enormous cloud of hydrogen‚ helium‚ and a few other elements and rocks. Around five billion years this cloud of materials began to spin and contract together into a disk shape under their own gravitational forces. The particles started combined together‚ protoplanets‚ to eventually form planets. A great mass of the material eventually began to form together‚ protosun‚ and make
