The biggest void known to mankind

The biggest void is a massive 1.8 billion light years across. It is also colder than than normal areas; this was one of the clues to finding it. Scientists were surprised by the scale of it but it can be explained by the Big Bang theory, or maybe it can't (don't you love astrophysics).

Incidentally, I would have thought that a void would be an empty space, but this void is not; it has "an underdensity of galaxies of around 30%". So basically it's an empty hole with only 70% of the number of galaxies which would be expected.

When Alice said "curiouser and curiouser" she could well have been talking about the universe.
