What is thought to be the origin of the solar system?

Question

BlackTom AI · Accepted Answer

The question asks about the origin of the solar system and provides what appears to be a single answer choice. 
Option presented: 'A large cold cloud of nebula that rotated slowly.' This description aligns with the widely accepted solar nebula theory, which posits that the Sun and planets formed from a rotating disk of gas and dust that collapsed under gravity and conserved angular momentum. 
Because no other options are supplied, we cannot evaluate competing hypotheses in this question, such as formation from a stellar collision, a hot cloud scenario, or alternative nebular models. 
In typical explanations, a giant molecular cloud contracts, heats up, becomes a protoplanetary disk around a new Sun, and progressively coalesces into planets through accretion, with the disk’s rotation playing a crucial role in shaping orbital dynamics. 
If you were to consider other possible statements, you would look for ideas like a sudden violent event, non-rotating collapse, or external perturbations, which would differ from the gradual, rotating nebular collapse described here. 
Given the standard scientific consensus, the rotating cold nebula origin is the core idea behind solar system formation, while alternative notions would require additional evidence to be considered plausible. 
Note: since the option set is incomplete, ensure in future items that all answer choices are provided to fully assess understanding and differentiate common misconceptions.
