Is that necessarily true in the earliest moments of the universe? Probably there are good reasons for it to be so that I don't understand, but then most of what cosmologists understand about the period that JWST looks back to is from extrapolating backwards, and it seems like the new observations it has enabled keep disagreeing with previous assumptions. Anyway, I really look forward to finding out what improvements to theory can be made to better explain anomalies like these lonely quasars or the apparently overdeveloped young galaxies.
