The secret Cold-War-era installation where Ye Wenjie discovers she can use the Sun as an amplifier to boost a radio transmission to interstellar power, and sends humanity's first reply to Trisolaris — the single act from which the whole saga flows.
Across The Three Media
📖 BOOKSTENCENT ’23NETFLIX ’24
The Red Coast dish, the Cultural-Revolution backstory, and Ye Wenjie's fateful broadcast are present in all three media — the books, Tencent's faithful Chinese series, and Netflix's relocated version (which keeps the Cultural-Revolution prologue and the young Ye Wenjie intact).
The Real Science [HALF]
HALF. Radio SETI is entirely real (Arecibo, the 1974 Arecibo Message), and the danger of broadcasting our location — the METI debate — is a live, serious argument among scientists. The dramatized part is the trick: using the Sun's plasma as a giant radio amplifier to reach four light-years is physically dubious as written. Real contact tech, fictional amplifier.
