The appropriate group of experts to review this material would be a Multi-Disciplinary Committee on Societal Biosignatures, consisting of Theoretical Astrophysicists, SETI (Search for Extraterrestrial Intelligence) Research Analysts, and Cliometricians (historians who use mathematical modeling to study societal collapse).

Abstract:
This analysis evaluates the "Eschatian Hypothesis," a proposed resolution to the Fermi Paradox formulated by David Kipping. The hypothesis posits that the first detectable extraterrestrial intelligence (ETI) signals may originate from terminal, high-energy events—"cosmic SOS" signals—rather than stable, long-term civilizations. This premise is rooted in observational bias, where extreme but rare phenomena (e.g., Pulsar planets, Supernovae) are often detected before more common, subtle ones. The input contrasts this hypothesis with anthropocentric historical data, noting that most terrestrial civilizations (e.g., Mayan, Cahokian, Han Dynasty) collapsed "quietly" without deliberate, high-energy signaling to external observers. The hypothesis suggests a shift in SETI methodology toward searching for anomalous transients—brief, non-physical energy bursts—using upcoming facilities like the Vera Rubin Observatory.
The Eschatian Hypothesis: Terminal Signaling and the Fermi Paradox
0:00 The Eschatian Framework: Introduction to David Kipping’s "Eschatian Hypothesis" (from the Greek eschatos, meaning "last"), which suggests the first alien signal detected by humanity will likely be the civilization's final, unstable transmission.
1:30 Terminal Phase Signaling: The core argument that detectable ETI signals may coincide with catastrophic or transitory terminal phases rather than periods of peace and stability.
2:09 Impact of Observational Bias: Analysis of how astronomical detection methods favor extreme, rare events over common ones; examples include the early discovery of Pulsar planets and Hot Jupiters, which are statistically rare but highly detectable.
3:39 Technological Supernovae: The application of the "supernova" detection logic to technosignatures, suggesting that a brief, momentary burst of extreme energy is significantly more likely to be detected than long-term, low-energy output.
4:26 Historical Signaling Analogies: Review of human historical use of high-intensity, short-duration signaling (e.g., beacons, smoke signals) specifically designed for urgent communication of critical or catastrophic events.
5:47 The Quiet Collapse Counter-argument: Evidence from terrestrial civilizations—such as the Maya and the Mississippian culture at Cahokia—showing that most societal disappearances occur gradually and without external signaling.
8:10 The "Fuzzy Signal" Case Study: A comparison of the Roman Empire and the Han Dynasty, illustrating that coexisting great powers can remain largely unaware of each other's status due to low-bandwidth, intermediary-dependent communication.
9:53 Non-Signaled Decline: Observation that the collapse of the Han Dynasty resulted in an inward-facing "blackout" of communication rather than a loud outward announcement, challenging the necessity of high-energy terminal signals.
11:51 The Toy Model Energetics: Calculation that a civilization must release approximately 1% of its total observable energy budget in a brief burst to be detectable as an Eschatian signal; for humanity, this equates to roughly 40 million tons of TNT per day.
12:55 Shift in SETI Strategy: Recommendation to move beyond traditional continuous signal searches toward the identification of anomalous transients—sudden explosions that defy known physical explanations—with specific expectations for data from the Vera Rubin Observatory in 2026.
13:11 Conclusion on Signal Intent: The hypothesis concludes that a detected signal is less likely to be a "hello" and more likely to be a "goodbye," serving as a final gasp of a collapsing technological entity.
