What is the name for the concept central to solar system creation driven by gravitational collapse of a nebula?
Answer
The Nebular Hypothesis
The Nebular Hypothesis is the central concept explaining how solar systems arise from these massive gas and dust clouds. This process is initiated when gravity overcomes internal pressures, causing the nebula material to contract. As this inward pull continues, the material concentrates, heats up, and eventually ignites nuclear fusion in the core, resulting in the birth of a star accompanied by a surrounding protoplanetary disk. The entire sequence hinges upon the dominance of gravity in condensing the initial diffuse matter.
