Where are these Aliens?

We want to find aliens, but they may not want us.

We all know that it is possible to be in various biological forms other than all the living things that live on the planet Earth, which we want to tell by the word ‘alien’. When we think about many dreams, we can not be alone in this immense stage; “The Drake Equation“, which can be used to estimate the number of civilizations that could exist theoretically:

Of course, we need to have a technological infrastructure that will allow us to research the data to return to these values. The Drake Equation is a simple and effective equation that helps us to understand how we are part of this universe, knowing that it is a natural product of the cosmic development of life, which, in addition to clarifying the factors involved in such an investigation, activates our intellectual curiosity about the universe. The main goal of the SETI Institute(The Search for Extraterrestrial Intelligence) is to do a better quality research that will provide additional information on any of the factors of this fascinating equation.

Is there the edge of the universe ?

If there are so many civilizations, where are they? For decades we have the technology to receive radio signals from a distance, but we rarely get any signal that we can say is a possible message. These were then often disproved as in the case where the pulsars were discovered. Despite the promise of some signals, the discovery of extraterrestrial life still continues to be a future event.

Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.
― Arthur C. Clarke


Fermi’s Paradox
fermisparadoxEnrico Fermi (1901-1954) thought that any civilization with adequate rocket technology and even the poorest amount of the imperial incentive could colonize the entire galaxy. Within ten million years, every star system could be taken under the wings of the empire. Ten million years may come to the ear for a long time, but our galaxy is quite short compared to its age. So the Colonization of the Milky Way should be fast.(The Milky Way is approximately 13.2 billion years old; This value is given by the minimum limit determined by the age of the star named HE 1523-0901, which is assumed to be the earliest star in our galaxy).

So Fermi’s idea was to have enough time for the aliens to cheer on their galactic beings. But when you looked around, there was nothing about their existence; The Fermi asked himself: “Where is everybody?” This incompatibility, which Enrico Fermi put forward, is called the “Fermi Paradox”. “Where is this extraterrestrial life that must exist? Why should they not colonize all the galaxies up to now if they exist?

The first thing to notice is that the Fermi Paradox is a very powerful argument. For the speed of the foreign spacecraft, you can say that it can move at 1% of light speed or 10% of light speed. Not important. You can also discuss how long it will take for a new star colon to form its own colonies. It still does not matter. Any reasonable assumption about how quickly colonization can take place will still result in a shorter time scale than the age of the galaxy. It’s like entering into a heated debate about whether 16th-century Spanish ships could go with two or twenty marine mummies. As a result, they quickly colonized America in both ways.

According to Brian Cox, a civilization with the ability to communicate between civilizations in space can not be expected to live a long life – because such a civilization would also have the ability to self-destruct at the same time. At the same time, the developments in science and technology will quickly overtake the development of institutions that can control themselves over time, and will politically lead to the destruction of civilizations themselves.

I do not think that we will survive a thousand years without leaving our delicate planet” says Stephen Hawking, who has the same idea with Cox. This idea is one of the best known answers, but as humanity, we do not like to think about it yet.

According to Neil de Grasse Tyson, our planet could even be a zoo created by aliens who want to watch stupid people.

Is the civilization destined to destroy itself? Or is the Fermi Paradox entirely different? Perhaps it is wrong that our understanding of how long the universe has survived, and we are only condemned to cosmic loneliness. Anyway, a lot of scenarios can be produced, let us listen to the advice Hawking gave us: “Look up at the stars; Not your feet below. “
