What if we can see things on the solar system plane because of some yet to be discovered laws of multidimensional physics that hide other objects from detection that live outside the plane. Maybe an infinite multiverse is all around us and we just don't have capabilities to see it with human senses or tools, or to comprehend how it interacts with what we can measure and detect?
