In 1994, the comet shoemaker-levy 9 was observed hitting jupiter. it was the first time that humans observed a comet hitting a planet in the solar system. how would this finding affect the status of the outside-in model and the inside-out model, in terms of the models being elevated to a possible theory? it supports the outside-in model but more observation is needed to elevate this model to a theory. it supports the outside-in model and justifies the model's elevation to a theory. it supports the inside-out model but more observation is needed to elevate this model to a theory. it supports the inside-out model and justifies the model's elevation to a theory.
