Aliens can hide in the ocean, says astronomer Alan Stern

The search for intelligent life outside the planet on other planets is an old issue. A few decades after the beginning of this research, many theories were proposed, trying to explain the reasons for our failure in this matter. One of the most famous theories is called Fermi Paradox. Named after the Italian physicist Enrico Fermi, and wondered why humanity did not meet life outside the planet to this day, if all buildings indicate that in our world there must be other civilizations capable of traveling between the stars.

Many have tried to answer this question. In the view of some, we simply look at where we need it. Others believe that foreigners are in hibernation. According to the third, we are the only technologically advanced civilization in the universe.

Alan Stern, the planet scientist and science pioneer in the New Horizons space mission, has this theory. He participated in the forty-ninth annual meeting of the Earth Planet at the American Astronomical Society.

As wrote, Stern came up with the idea that extraterrestrial life might already exist in other parts of our galaxy, but probably lives deep in the dark ocean beneath the surface of the planets. Such oceans must surely exist in our galaxy, at least because there is in our own solar system - Pluto, Saturn's moons, Titan Saturn satellite, to name a few. The underground oceans, according to Stern, can give life more time to develop and protect against the impact of external threats, which usually affect any exposed surface of the planets.

"Solar flares, supernova explosions, orbital peculiarities, the presence or absence of a magnetic envelope and the atmosphere - all of these factors in this case are not important," Stern said.

Stern was able to continue to look at his theory. He also suggested that extraterrestrial civilizations, all living under the surface, may have no doubt about another super-surface world. If so, these civilizations certainly know a few of us around the surrounding galaxy. Unfortunately, if these civilizations want to establish contact with someone (in this case with us), we probably will not be able to detect the signs of these attempts. Of course, low-frequency radio waves may help, but even in their presence, the detection opportunity will be very low.

Fixed life in the ocean can only postpone its mark. With the discovery of the possibility and desire for interstellar mobility, these civilizations must seek a solution to the serious problem associated with life support systems, since these civilizations will certainly work on water in the first place. On an incredibly large volume of water. Water, you know, is a very heavy material. Therefore, even if their planet's orbit enters Earth, these civilizations will have to use large quantities of fuel that are more important for dispersing the spacecraft.

However, Stern's theory is only a theory. The astronomer never saw this as a final answer to Fermi's paradox.

    "Maybe this puzzle has no answer." My theory only adds a new element to discuss the issue, "- says the world.

Humanity will undoubtedly continue to search for intelligent life outside the planet, and its discovery will undoubtedly be the greatest in human history. Precisely to predict when this happens, we can not, but at least we will have a plan to take further action when this time comes.
