The bright lights of downtown seen from our distant suburb
Is our planet at the centre of a giant cosmic void? If the hypothesis gets rid of dark energy, I am all in favour of it. It might also account for why the Earth has yet to be sterilized by Berzerkers.
our uncertainty about galaxy distances allows an interesting possibility. The distribution of matter could look the same in all directions, but vary with distance from us. In particular, we might be sitting in the middle of a "void" - a vast spherical bubble in an otherwise homogeneous universe. This bubble is not devoid of matter. In fact, most of the stars and galaxies we can see from Earth would be contained within it. It's just that everywhere beyond it, which is too far away to see, the density of stars and galaxies is much higher.
