Beacon in the Galaxy (BITG): A 204,000-bit METI-Style Binary Message Proposal to the Milky Way Using FAST and the Allen Telescope Array

To the point

BITG is a METI plan to send a binary, MATLAB-generated interstellar message to a carefully chosen Milky Way region using FAST and the Allen Telescope Array, expanding on the Arecibo message by outlining universal math and physics, hydrogen-based time and length units, a timing anchor to cosmic age, a 3D galactic reference frame from globular clusters, sections on Earth and life, Solar System maps, and Earth's crust and atmosphere, with an explicit reply invitation and a galactic address, created by Jonathan H. Jiang and colleagues in 13 parts (~204,000 bits), encoded for delivery, and it argues for upgraded observatories and precise timing to target 2–6 kpc from the center on specific dates, while acknowledging the debate about contacting ETI but presenting BITG as a practical step toward interstellar dialogue and future content ideas.
