What I like about these 31 newly identified ancient quasars

What I like about these 31 newly identified ancient quasars from Euclid is that they’re not “breaking cosmology,” they’re tightening the constraints on how fast massive black holes could form after the first stars lit up. Every time we find more of these early bright objects, the interesting question becomes less “are they impossible?” and more “which growth pathways did we underestimate?”
