How I independently conceptualized Exoplanets and Galactic Rotation through a thought experiment on cosmic hierarchy

Hi everyone,

I recently had a thought experiment about our solar system and cosmic mechanics that I wanted to share with the community to get your perspective.

I started thinking about how our Sun revolves around the center of the Milky Way in a fixed galactic orbit. If the Sun is orbiting something, there must be a massive central body or gravitational mass pulling it—which led me to learn about supermassive black holes (like Sagittarius A*) and galactic center dynamics.

This led me to a conceptual framework:

Re-framing the hierarchy: If we view the Sun as a "planet" orbiting the galaxy's center, then our planets (Earth, Jupiter, etc.) act functionally like "moons" orbiting the Sun.

Extending the pattern: Applying this logic to the rest of the galaxy, the billions of other stars orbiting the galactic core should also have their own "moons" (planets) revolving around them.

Implications: This cosmic pattern implies that planetary systems are the norm across the galaxy, making the existence of exoplanets and potentially life elsewhere statistically very high.

I later found out that astrophysics already confirms these concepts under terms like Galactic Rotation, Exoplanets, and Exomoons. However, arriving at this nested hierarchy purely through logic was an exciting exercise for me!

How do you usually explain this nested structure (Moon --> Planet --> Star --> Galactic Core) to beginners or space enthusiasts?

I'd love to hear your thoughts!
