It's Official: We Were WRONG About the Big Bang

Here's a maybe silly question, and maybe exactly what you talked about. But if the universe didn't expand from one single point, but was rather just more tightly packed together - is the theory that everything is expanding everywhere and every atom or sub atomic particle the raisons you talked about? Like if every sub atomic particles all expanded from each other in a constant way, there would be no way for us to measure it right because it becomes relative to everything else and what was once "X distance" between two particles later also is "X distance" because our measuring of them is in a way expanding along side it? Though the "raisons" far away from us have so much materia between, we could actually see them going away from us? Like, if every atom is constantly getting bigger, we wouldn't notice because everything is getting bigger and expanding...

Well, my mind is also blown, so I have no idea what I'm talking about :D
