Their theory posits that if in fact Earth and our surrounding neighbors are in fact in an unusual or special region of space, ie, a void, then our perspective on the universe would be severely challenged

If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.
Rene Descartes

An axiom methinks.

Gravity collects mass, and bends space-time, so why couldn't it collect space-time? After all of these billions of years, the fabric of space of space-time must be spread pretty thin over the void. Perhaps it's sprung a few leaks. Could also mean that the universe is bigger than we thought, because we didn't take the voids into account.
