I think it is a more than a little weird, as we find that over different scales our ability to predict loses its precision. We attribute this to an unknown something, that is sometimes referred to as "dark matter", but in reality is something we have not directly observed. Dark matter is essentially a placeholder for our ignorance, but with a little bit of assumption sauce thrown in.
