Aliens are buried under glaciers. Are aliens living deep in the planet’s core?

Will there be too many aliens buried on the ice? That’s exactly what planetary scientist Alan stern of the Southwest Institute in Boulder, Colorado, has come to the conclusion that this may delay human contact with alien civilizations.

Most extraterrestrial life is likely to be in the “depths” of their planetary home, the underground ocean surrounded by frozen ice cores. The idea was put forward by scientists at this year’s meeting of the Department of planetary science of the American Astronomical Society in Pru, Utah.

This hypothesis may explain the lack of signals from other technologically advanced civilizations, which is a problem called Fermi paradox.

Astronomers have only recently begun to realize how common oceans are in our solar system – evidence of their existence can be found on many moons of Jupiter, Saturn, Neptune, and even distant Pluto.

The crust of these planets is mainly made up of water ice. Water ice forms towering mountains and cracked canyons on the surface of celestial bodies, but melts into liquid water at lower depths.

These hydrothermal vents may inject nutrients into the surrounding environment, similar to the ecosystem at the bottom of the earth’s ocean. These “kindergartens” of life protected by thick ice crusts are even more productive than the environment to which humans are exposed.

If the creatures living in the cold ocean world could evolve into intelligent creatures, they might not understand the meaning of the night sky as humans do. Stern speculated that, perhaps different from the human “space program”, their “space program” is only to reach the frozen surface of the earth.

Stern’s idea is not based on new evidence, but is the first to link the universality of the icy ocean world to the lack of extraterrestrial signals.

Psychologist Douglas Wacker, President of the society for extraterrestrial intelligence bioinformatics in San Francisco, California, said the idea was very attractive, although he didn’t think it was necessary to cite Fermi’s paradox. It’s difficult to detect biochemical markers remotely, and new telescopes and technologies are likely to be needed to find them, Vakoch said.

If they don’t find us first, it may be because they don’t think long-distance communication is worth it, especially if they think other people are trapped in their own little ice bubbles, Stern said.

Fermi paradox was put forward by the Nobel Prize winner and physicist Fermi. The meaning of Fermi’s paradox is that theoretically, humans can fly to every planet in the galaxy within one million years, so aliens should come to earth now, as long as they evolved one million years earlier than humans.

In other words, Fermi paradox shows the contradiction between overestimating the existence of alien civilization and the lack of relevant evidence.

At present, the search for extraterrestrial intelligence includes SETI project, which is dedicated to receiving electromagnetic waves from the universe with radio telescopes and other advanced equipment, and analyzing conventional signals in order to discover extraterrestrial civilization.

SETI plans to use a large electronic telescope to detect “sounds” that receive external radiation, including background radiation, radio waves from stars, and other noises.

Scientists will analyze these signals by computer, hoping to find information from aliens.
