Could our universe be part of a larger atomic-scale system?

This isn't about science fiction, but about the logical extremes of scale invariance and hierarchical models in physics. We model atoms with solar system-like orbitals, and galaxies cluster in web-like structures. I'm wrestling with whether this self-similarity could extend upward, making our cosmos a component in an unfathomably grander scheme. It's a question about the fundamental nature of reality and our place within it.

I’ve engaged with this fascinating thought experiment many times. While a compelling metaphor for popular discussion, as a scientific model it faces severe challenges. The scaling of forces is the primary issue; the relative strengths of gravity, nuclear, and electromagnetic forces are finely tuned constants in our universe. An “atomic” mega-universe would have a completely different set of fundamental interactions and constants. Therefore, while logically possible, it’s physically implausible as a literal description, as it cannot account for the specific laws we observe.

Thank you that’s really helpful. I like the idea as a metaphor, but your explanation makes it clear why it doesn’t work as a physical model.

Adding to that, modern cosmology already explores related ideas in a more rigorous way, such as multiverse theories or brane-world models. These don’t rely on simple size-scaling analogies but instead emerge from attempts to unify gravity with quantum mechanics. Even then, these ideas are highly speculative and currently lack direct experimental evidence.
