By this I mean does the Kuiper belt a necessary and vital part of our solar system. There could be several interpretations to this question. Here's mine in the beginning I think the collection of matter happened from magnetism within the metals of the Kuiper belt and that it being pushed out to the outer rim of the solar system was ideal. I do believe however that the Kuiper Belt although interesting and we may be able to learn from it, I can see that there is something to learn on how these formed, why they formed, the significance and insignificance of the Kuiper Belt. The more the human race discovers about the belt could change our perception of the early solar system and make give us some hidden information about our own world, and how it affects the people on this planet. The Kuiper is a necessity at this point because it hasn't been studied enough to this point.
