A new study, how many space space the scientists have managed to explore. How much time we have invested in searching for extraterrestrial life. And still without a clear result. The extraterrestrial signal or the confirmation of extraterrestrial civilization, according to research published in Astronomical Journal, was not found precisely because we do not exactly know what we're looking for. So we do not even notice that we could find it long ago.

Alien life is like a needle in a haystack. But how many hits did we see? If we do not know exactly how the needle looks, how can we start looking? We are waiting for a clear signal from aliens "Hello, here we are!". Maybe we just didn't notice the signal, though it did. Are we watching the right signals?

Students and research

Postgraduate students of astronomy at Penn State University attended a seminar workshop NASA in Houston. Astronomers wanted to accurately calculate how an extensive search for extraterrestrial intelligence or SETI had already been performed by that date.

Simply - the group constructed a mathematical model space-based 33 000 light years. They also verified the 60 years of the SETI project and also included the 8 of different types of search for alien civilizations. Their calculations revealed how small the space we have explored.

“The researchers found that human collective search for extraterrestrials was about 0.00000000000000058%. We could compare it to a bathtub full of water in all the oceans on Earth. ”

If we do not know what to look for, we can not even find it. We can compare it with another analogy: We will drink a glass of seawater to discover fish in the sea.

Modern binoculars

The new era offers more advanced technology and modern binoculars that can greatly help in finding a stop for extraterrestrial civilization. There are also many enthusiastic ideas and practices on how to find these traces. For example, astrophysicist, astrobiologist and scientific educator Brendan Mullan he believed that one way we could find alien civilization was to look for infrared radiation and the heat drained from the spheres of the Dyson sphere.

What is Dyson's sphere?

Dyson sphere (Dyson sphere) is a hypothetical superstructure that would allow the use of absolutely all the energy released by the star. The American designed it Freeman dyson, according to which she also gained her name.

The sun and its entire planetary system is enclosed in a sphere from which the inner wall receives energy and which can be used for eventual colonization and expansion of usable area even out-of-planet settlements throughout the system. Dyson's sphere is one of the less frequent topics of science-fiction literature or programs, but it also appeared in such series as Star Trek, but also in the superhero film Avengers: Infinity War, which takes place in part in the universe.

For example, Dyson predicted that similar structures would be a logical consequence of the increasing energy demands of a technologically advanced civilization. He proposed that such structures be searched to find evidence of a highly intelligent extraterrestrial life.

The author of Dyson's concept is physicist and mathematician Freeman Dyson, who realized that every civilization, evolving in the same way as humanity, increases with its development the demands on energy consumption. If this civilization exists for a long time, there will be a time when it will have to use all the energy of its star. That is why he assumed that he would create a system of structures orbiting the parent star so as to capture all the energy this star produces.

Searching for extraterrestrial life

If alien civilization lived at a similar pace as humans, it would use more and more energy every year. One day they would turn to the source - the sun. However, Mullan and his colleagues have not yet found any signs after many observations Dyson swarms.

Even though it is does not prove that there are no foreign civilizations, maybe something else shows us. Even advanced civilizations must still work in the laws of physics. If this civilization exhausts too much energy, it could destroy itself.

Dr. Mullan adds:

"If we use more and more energy every year, it could make it impossible for our planet to live until the end of the 24th century, if not sooner."

The ways in which we are trying to find extraterrestrial civilization are finally can help to understand that we have to take care of our planet and strive to create a sustainable and prosperous future for themselves and their descendants. Otherwise, the Earth will soon show us another exclamation mark, such as natural disasters, global pandemics, etc.

Michael Hesseman: Meeting Aliens

If extraterrestrials visit Earth, why do they come and what should we learn from them? "Uphology" will never become a science because at the moment of understanding who controls the spacecraft, they will cease to be "unknown flying objects".
