Why Advanced Alien Civilizations Might Self-Destruct Before We Find Them

The Fermi Paradox has long puzzled scientists by questioning why no signs of advanced extraterrestrial civilisations have been detected. In 2022, researchers Michael Wong and Stuart Bartlett proposed a new explanation called the Collapse-Homeostasis Hypothesis. Their theory suggests that civilisations either collapse or stabilise in ways that make them difficult to observe from afar. The Kardashev Scale categorises civilisations by their energy use into three types: Type I harnesses planetary energy, Type II taps into stellar energy, and Type III exploits galactic energy. Wong and Bartlett argue that many civilisations fail to progress smoothly through these stages. Instead, they often collapse before or during their transition to Type I due to unsustainable energy demands and societal strain.

The hypothesis warns that rapid expansion without restraint leads to a critical breaking point or singularity. Some societies may avoid this fate by recognising the risks and shifting priorities inward. These civilisations enter a state of homeostasis, focusing on stability rather than outward expansion. Such societies become harder to detect as they no longer seek to spread across galaxies.

Certain technological advancements, like blockchain, can worsen instability by increasing energy consumption without improving systemic balance. However, breakthroughs in energy production or population control can sometimes delay collapse. These temporary solutions buy time but do not guarantee long-term survival. The Collapse-Homeostasis Hypothesis offers a possible answer to the Fermi Paradox by explaining why galaxy-spanning civilisations are absent. It suggests that many either collapse or adopt low-visibility lifestyles focused on internal equilibrium. This aligns with the lack of observable evidence for advanced extraterrestrial societies.
