What are the stages?
- The blast wave compresses the gas and dust cloud. It now begins to be attracted to other molecules by the force of gravity.
- The debris begins to compress and spin. Over time it forms a disk.
- Larger particles begin to collide with other particles. They fuse together forming even bigger ones. As they grow, the gravitational attractive force that they exert begins to increase.
- Eventually all the debris in a path is swept up leaving a single large body called a planet.
What evidence supports this theory?
- The chemicals that make up the solar system are all the same age.
- The planets of the solar system all rotate on the same orbital plane.
