What theory explains the formation of stars and planetary systems from nebulae?
Answer
Nebular Hypothesis
The comprehensive theory describing how a central star surrounded by a flattened disk of leftover material evolves into a full solar system is termed the Nebular Hypothesis. This concept posits that the entire process—starting from the collapse of a large, rotating cloud of gas and dust—is the universal mechanism for birthing stars and their attendant planetary bodies. The necessary angular momentum that prevents all material from falling onto the central star and ensures material orbits in a planar structure is provided by the initial spin of the nebula.
