One interpretation is that these are older (more red shifted), larger (more stars) galaxies. But that's just one explanation. A pretty good one, but still, it could also be something totally mundane and boring. Remember FTL neutrinos?
I'll be ecstatic if the existing model of the universe needs a massive update based on this new data. But it's important to search as hard as we can for answers that aren't the one we really want to see.
- joe__f 4y agoIt's much more reasonable to think about changing the cosmological or galaxy formational models than it is to consider adding FTL neutrinos. I remember thinking the FTL neutrinos were nonsense as soon as I saw it. You're right that this could be explained differently given time, but it at least seems plausible to me that it could be real.
