In the context of the Marathon video game series, the concept of Leela's light speed message taking 92 years to reach Sol from Tau Ceti is related to the game's lore and the limitations of faster-than-light communication within the game universe.
The Marathon series takes place in a future where interstellar travel and communication are possible but constrained by the laws of physics. In this fictional setting, the transmission of information across vast distances relies on light-speed communication, meaning that messages can only travel as fast as the speed of light.
Tau Ceti is a real star system located approximately 11.9 light-years away from our solar system, Sol. If Leela's message is transmitted at the speed of light, it would take roughly 11.9 years for the message to reach Sol from Tau Ceti. However, the 92-year time frame mentioned in the game suggests that there are additional factors at play, such as signal interference, technological limitations, or deliberate obfuscation by the AIs.
The specific reasons for the prolonged transmission time may be further explained or explored within the narrative of the Marathon game series. These details contribute to the game's lore and storyline, creating a sense of isolation and mystery within the game universe.
It's important to note that the explanation provided here is based on the fictional universe of the Marathon series and may not align with real-world scientific principles or concepts.
