TL;DR

The paper proposes that advanced civilizations must transmit information into space to avoid self-imposed isolation, which could lead to extinction. It argues that active METI (Messaging to Extraterrestrial Intelligence) is a critical survival imperative for civilizations seeking long-term existence.

ABSTRACT

Transmission of the information into the Cosmos is treated as one of the pressing needs of an advanced civilization. The inability to meet this need, the forced withdrawal into self-imposed isolation can lead to the extinction of civilization.

Motivation & Objective

• To address the existential risk posed by the absence of interstellar communication by advanced civilizations.
• To highlight the danger of self-imposed isolation due to the refusal to transmit signals into space.
• To establish the transmission of information into the cosmos as a necessary condition for the long-term survival of advanced civilizations.
• To position METI not as a speculative endeavor but as a fundamental requirement for civilizational persistence.

Proposed method

• Analyzing the long-term survival prospects of civilizations that refrain from interstellar communication.
• Modeling the consequences of a civilization's decision to remain silent in the cosmic context.
• Drawing analogies between self-imposed isolation and extinction risk in advanced technological societies.
• Using logical and philosophical reasoning to frame METI as a rational, survival-oriented action.
• Emphasizing the role of proactive information transmission in maintaining a civilization's presence in the universe.

Experimental results

Research questions

• RQ1 What are the long-term consequences for a civilization that chooses not to transmit signals into space?
• RQ2 How does self-imposed isolation in the context of interstellar communication increase the risk of extinction?
• RQ3 Why is active messaging to extraterrestrial intelligence (METI) considered essential for the survival of advanced civilizations?
• RQ4 What is the relationship between interstellar communication and the persistence of technological civilizations?
• RQ5 How does the absence of transmission affect a civilization's ability to remain detectable or influential in the cosmos?

Key findings

• The failure to transmit information into space can lead to a civilization's isolation and eventual extinction.
• Self-imposed silence in the face of cosmic communication opportunities constitutes a significant existential risk.
• Transmission of information into the cosmos is not optional but a necessary condition for the long-term survival of advanced civilizations.
• The absence of METI may result in a civilization becoming undetectable and thus effectively extinct from a cosmic perspective.
