The Big Bang, the Big Bang - The Biggest Bang

The James Webb telescope made a discovery of galaxies that were apparently existing between 400 and 325 million years after the universe began r right? And so that doesn't sound crazy on its surface, until you realize that the previously established theories did not suggest that galaxies could even have formed at that time. So where i'm going to presume actually, is like something that i've thought about a lot. Like, the universe looks 13 point eight billion years old from where we are. But there's no edge of the universe as far as i know - it also has a 13 point 8 billion light ear bubble around it.
