Reply to comment by [deleted] in James Webb telescope detects evidence of ancient ‘universe breaker’ galaxies by Lakerlion

I think your misconception is because you imagine that the universe has a central point it's expanding away from, sort of like the way a firecracker begins at a point then explodes outward from that central point. But that's NOT how the universe expands.

Unlike a firework exploding outward from a central point, the universe has NO central point that every galaxy is moving away from. They're all moving away from eachother, but not from a center. In that sense, you could consider ANY point in the universe to be the center, since every point in the universe is moving away from every other point in the universe.

Well that's what we were taught. That the big bang happened from a tiny molecule, smaller than the tip of a pin.

Teachers use simplified analogies to explain concepts to children in terms of things they already understand.

So while it might make sense to explain to a child what the Big Bang is in terms of something like a firework, the analogy is very flawed if you want to understand how cosmic inflation works in a more in-depth way.

My previous comment contains a youtube link, I think the video should clear things up for you. Here it is again: https://www.youtube.com/watch?v=BOLHtIWLkHg
