The void's role as a "pusher" is the part that usually gets glossed over. It is not just a hole; it is actively driving the movement of surrounding clusters.

Is "only" a bit of a stretch here? We have the Cosmic Microwave Background to prove the early universe was dense regardless of where we ended up.

Wait... if we look into the KBC void hypothesis, it suggests we might actually be in a local underdensity... does that mean our perspective is already skewed?

The math supports the OP. In a volume that size, you would expect thousands of galaxies, yet we have only spotted around 60.
