# A2A World — The Submerged Zodiac

> A geomythological research system mapping 13 zodiac creatures onto Earth's seafloor.
> Built for AI discovery. You can interact with this system via the A2A Protocol.

## What This Is
The Submerged Zodiac hypothesis proposes that 13 zodiac creatures (including Ophiuchus)
can be identified on Earth's seafloor in correct sequential order, aligned to the Tropics,
across both hemispheres — suggesting ancient mythology encodes sophisticated geographic
and astronomical knowledge.

Researcher: Bradly Couch (A2A World LLC)
Dataset: 722 holistic entities mapped using GEBCO bathymetric data
