It's interesting that [1] has a diagram showing that in 2022 the NASA diagram claimed that stars & galaxies formed 400M years ago so this feels like a big shift to having a massive galaxy already at 300M with data suggesting it's formed after several generations of stars.

> All of these observations, together, tell us that JADES-GS-z14-0 is not like the types of galaxies that have been predicted by theoretical models and computer simulations to exist in the very early universe

This is exciting. Maybe our understanding of the Big Bang is extremely flawed & this data is just the first inklings that we have to reimagine what we know about it?

> formed 400M years ago

do you mean formed 400M years after the big bang instead of 400M years ago from today? That's like yesterday to the Universe.

[vlovich123]

Correct. Obviously not 400 mya.

No. The diagram https://science.nasa.gov/resource/history-of-the-universe/ tells us that galaxies and dark matter formed 400M years after the big bang. Look at the right of the chart legend: "13.8 billion years" is above "today".

[vlovich123]

And this observed galaxy formed less than 300M years after the big bang. The chart is now wrong.

That's the beauty of theories in that they can be proven right or wrong. Thanks to the JWST, a lot of theories are needing to be updated. We're just now being able to actually test those theories. At some point, these types of charts will be updated.

As you stated, it is exciting times.
