What’s interesting about Euclid’s 31 early quasars isn’t

What’s interesting about Euclid’s 31 early quasars isn’t just “we found more.” Some appear so luminous that they strain the usual timelines for how supermassive black holes grow in the first billion years after the Big Bang. That doesn’t mean physics is broken, but it does mean our models for early feeding, mergers, or obscuring dust may still be missing part of the story.
