Today, perhaps, only a few scientists believe that Earth is the only place in the Universe where life exists in all its diversity.
Astronomers regularly discover potentially habitable or at least habitable exoplanets, but humanity still has no proof of the existence of extraterrestrial life.
A study conducted as part of the SETI (search for extraterrestrial life) project shows that the probability of the existence of highly developed extraterrestrial civilizations is extremely high, but we cannot come into contact with them because they undergo, for example , climate change.
On distant exoplanets, just like on Earth, the seasons also change, climatic conditions change and, most likely, not for the better.
Extraterrestrial civilizations have probably found themselves in a situation where their planets have become practically unsuitable for normal life.
In order to survive a difficult and life-threatening time, progressive ETs may deliberately enter a state of suspended animation or commonly referred to as “biostasis”.
Biostasis is the temporary slowing or stopping (short or long term) of biological functions in order to preserve physiological capacities.
Representatives of SETI are convinced that dozens of highly developed civilizations inhabit the Milky Way, with which we cannot come into contact because they are dormant.
“Some living organisms have proven that biostasis helps them survive in extreme conditions,” said SETI Principal Astronomer Seth Shostak. “Representatives of extraterrestrial civilizations, being locked up on their own planet, could consciously “hibernate”, waiting for the natural stabilization of climatic conditions. »
Some scientists believe that if humanity does not find a way to stop global warming and does not begin to urgently colonize objects in the solar system, then we will also be forced to resort to hibernation in order to save at least a piece of our species.
