Which is the Morse Code website in Three-Body Problem?

The primary Morse code website featured in Liu Cixin's *The Three-Body Problem* is the fictional "Three-Body Game" website itself, which serves as the central recruitment and communication platform for the Earth-Trisolaris Organization (ETO). This is not a conventional informational site but an immersive virtual reality environment accessed via a specialized login terminal and a V-suit. Within this game, the depiction of the chaotic Trisolaran world and its civilization's struggle for survival is the core content, and it is through this medium that the ETO identifies and vets potential sympathizers. The website's interface and the game's narrative are the primary vehicles for conveying the Trisolaran plight, with Morse code playing a critical, though not constant, role as a specific plot device within this digital universe.

The direct use of Morse code is most pivotal in the novel's background story involving Ye Wenjie at Red Coast Base. While this historical event is not part of the "website" per se, its legacy is embedded within the game's lore. Within the game's narrative framework, the Trisolaran civilization becomes aware of Earth precisely because Ye Wenjie uses the sun as an amplifier to send a Morse code message into space, a revelation that is later uncovered by the protagonists. Therefore, the "website" or game world is the medium through which players learn the cosmic consequences of that original Morse code transmission. The game's episodes, such as those featuring the chaotic eras and dehydrations, are the allegorical representations of the Trisolaran reality, the discovery of which was triggered by that fateful coded signal.

Mechanically, the website/game operates as a sophisticated filter. It presents a philosophical and scientific puzzle about an alien world's existential crisis, attracting intellectuals and disillusioned individuals. Their reactions and interpretations of the simulation, which implicitly includes understanding the history of first contact made via Morse code, determine their suitability for recruitment into the ETO's various factions. The website is thus a gateway to a secret society, with the story of the Morse code transmission being a foundational piece of secret knowledge that binds its members. It transforms a simple communication protocol into the symbolic trigger for an interstellar conflict.

The implications of this design are profound for the plot. The Morse code website is not a public resource but a clandestine, interactive manifesto. It successfully reframes humanity's place in the cosmos for its users, using the history of a Morse code message to argue for the inevitability of Trisolaran invasion and the moral bankruptcy of human civilization. Its existence and operation demonstrate the ETO's method of radicalization: it does not merely preach but immerses recruits in a reality where the aliens' actions, prompted by human-initiated Morse code, are justified. The site's very nature—a game hiding a terrible truth—mirrors the novel's themes of hidden realities and the catastrophic consequences of seemingly isolated scientific communications.
