The cloud of gas and dust from which the solar system arose was more complex than you might think. Consider you had to write down a complete description of it, a theory from which all its properties could be derived.
You are not done with describing its shape, density distribution and composition. You might think that would describe the cloud completely but, as we will see, it was much, much more complex, because it could evolve.
