5/9 The problem may lie closer to home than we thought.

Enter the KBC void: a massive depression in space stretching two billion light-years wide. It's only 10-20% less dense than average, but that might be enough to mess with our observations.

Question of the day: does someone know a (recent) catalogue of galaxy groups & clusters in our local universe with redshift-independent distances, redshifts and member galaxy properties like vel-disps? (we know Cosmicflows we are rather thinking of DESI or so)
