A viral post on X claims interstellar object 3I/ATLAS emitted a Fibonacci-pattern pulse signal — 8 • 13 • 8 • 5 • 13 • 8 — at 1420 MHz. The account named @surajit_ghosh2, decoded the signal as "Observe. Prepare. Understand. The Gate Awaits." However, no observatory, space agency, or SETI-affiliated facility has confirmed this detection.
