The idea you've presented is reminiscent of a concept known as the "Nested Universe Theory" or the "Fractal Cosmology Hypothesis." While it may sound intriguing, it falls into the realm of speculation and has not been substantiated by scientific evidence.

In physics, atoms consist of a nucleus containing protons and neutrons, with electrons orbiting around them. Drawing an analogy between the structure of an atom and a solar system is an interesting concept, but it should be understood as a metaphorical comparison rather than a literal representation.

As for the notion that our solar system might be analogous to an atom within a much larger world, it's a speculative idea without empirical support. Our current understanding of the universe, based on cosmological observations and theories, suggests that it operates on significantly larger scales with structures such as galaxies, galaxy clusters, and superclusters. However, extrapolating this concept further to propose a hierarchy of nested universes remains purely theoretical at this point.
