Is There a Difference Between the Age and the Mass of the Galaxies?

It could be that these galaxies actually are maybe younger than what we initially think, and son that everything is fine. But then the other possibilities tat maybe our models are a little bit off. There's also a lot of uncertainty in the mass measurements. Overall, people are excited about this data,. but i'd say it's still too fuzzy to draw any strong conclusions. Nobody likes it when photos make you look older than you really are. That's always a bummer.
