Why has humanity never been visited by aliens (as we know it)? This question has puzzled scientists for decades, but two researchers have come up with a possible – and unsettling – explanation: Advanced civilizations could stagnate or die out. before the chance.
The new hypothesis suggests that, as space civilizations grow in size and develop technology, they will eventually reach a crisis point, where innovation can no longer keep up with demand for energy. What happens next is the crash. The only alternative, the researchers say, is to reject the model of “invincible growth” in order to maintain equilibrium, but at the cost of one’s ability to expand across the stars civilization.
Argument, published May 4 in the journal Royal Society Open Sciencetry to find a solution for Fermi .’s paradox. Taking its name from the ordinary lunchtime thoughts of Nobel Prize-winning physicist Enrico Fermi, the paradox draws attention to the contradiction between the vast range and age of The universe – two things suggest that the universe should be filled with advanced alien life – and a lack of evidence that extraterrestrials exist anywhere in sight. “So where’s everyone?” Fermi is said to have commented.

The researchers of the new study say they may have the answer.
“Civilizations collapse from exhaustion or redirect themselves to priorities homeostasisAstronomers Michael Wong of the Carnegie Institution for Science and Stuart Bartlett of the California Institute of Technology, write in the study, making them difficult to detect from a distance. – homeostasis or collapse of civilization – would be appropriate for the absence of [galactic-wide] civilizations. “
The two came up with their hypothesis by studying studies of the “super-linear” growth of cities. These studies suggest that cities grow in size and energy consumption at an exponential rate as their populations grow, inevitably leading to crisis points – or singularities – that cause a rapid collapse in growth, followed by an even more severe collapse, potentially ending civilization.
“We hypothesize that once planetary civilization transitions to a state that can be described as a virtually connected global city, it will face ‘asymptotic burnout’, an eventual crisis in which the singular-interval time scale becomes smaller than the innovation time scale,” they wrote.
The researchers suggest that these collapsing civilizations would be the easiest for humanity to detect, as they would dissipate large amounts of energy in an “extremely unsustainable” way. “This suggests that many of humanity’s early discoveries of extraterrestrial life may have been made by intelligent, though not unwise, people,” the researchers wrote.
To prevent their demise, the researchers suggest, civilizations could undergo a “homeostatic awakening process,” redirecting their production from unrestricted growth across regions of the world. why to a priority of social welfare, sustainable and equitable development and harmony with their environment, the researchers suggest. While such civilizations may not give up space exploration entirely, they will not expand on a large enough scale to make contact with the Earth. The earth likely.
The researchers point to some “small awakenings” of humanity that have resolved global crises on Earth, such as reducing the global stockp of nuclear weapons from 70,000 warheads to less than 14,000 warheads; stop the hole that once developed in the Earth’s ozone layer by banning chlorofluorocarbon emissions; and the 1982 international whaling ban.
However, the scientists stress that their suggestion is simply a hypothesis, derived from observations of the laws that appear to govern life on Earth, and is designed to “stimulate the discussion, introspection, and future work.”
Their proposal joins countless other popular and scientific suggestions as to why we’ve never had direct contact with celestial visitors. These include many practical challenges posed by interstellar travel; that aliens may indeed be secretly visiting; or aliens arrived on Earth too early (or humans too early) in the life of the universe for direct contact.
Another theory, published April 4 in the Astrophysical Journal, posits that the sheer scale of the universe means it could take up to 400,000 years for a signal sent by an advanced species to reach other species received – a period much larger than the short period of time when humans were able to sweep the sky.
