Timothy Clifton, at Oxford University, said in an interview published at Space.com on October 1, 2008 that the solar system might be enclosed in a volume of space having a disproportionate lack of matter. According to his "void model," light from far-distant objects appears dim, not because the objects are retreating from the earth or even because the cosmos is expanding, but because the void condition does not focus the light as a matter-filled cosmos normally would. Clifton expresses one misgiving about his model that clearly reveals his worldview, however: it would negate the so-called Copernican Principle and require astronomers and cosmologists to regard the earth as a special place.<ref name=Clifton>Moskowitz, Clara.
