In the Star Trek universe, almost all of the Federation’s capital ships have one universal feature, the ‘Saucer Section’. This is often the main hull of the vessel, with some designs like the Miranda, NX, and Faraday class having no secondary-hull at all..

But why a saucer-shaped disk?
What if the disk shape wasn’t just aesthetic but had a practical purpose. What if the internal structure of the disk was spinning and producing artificial gravity through centripetal force?


Schematics and blueprints created of the USS Enterprise and other ship designs have detailed drawings of the internal decks of the saucer section and no, my theory is not-canon. Pitty.
If perhaps if they ever do a series set before the ‘Enterprise’ timeline, a pre-prequel, they could show a centrifuge-disk design in use on Starfleet vessels before they developed ‘gravity plating’ technology? Why would starship designers keep that aesthetic after it served any practical purpose? For the same reason parts of a ship are still called the ‘bridge’ and ‘forecastle’; Tradition.
