Do JWST galaxies strain ΛCDM?

Do early galaxies strain the standard model, or the assumptions used to estimate their masses? A good answer distinguishes revised estimates from a conflict that survives them.

Dru's spoken stance is that the mass revisions matter. The Hubble tension question is another test of how measurement and physics come apart.

Sub-questions

• Which mass estimates were revised?
• What assumptions drove the revisions?
• Which galaxies still strain the model?
• What observation would settle the disagreement?
