EXOPLANETA K2-18B | Mars has already arrived. This is known

Los Scientists were trying to know if humanity was not alone in the universeThe hope that increased when astronomers announced this week that they had discovered the most promising signs of life on a planet outside the solar system.

A British American team was discovered in the atmosphere of the external planets K2-18B, the “most promising” effects of “the most promising” of a possible presence of life, in a study whose results must be confirmed.

the milky wayThe galaxy where the Earth exists, It has been around about 10,000 million years ago and has more than 100,000 million stars. It may include a number of planets that are likely to be residence.

But looking at the age and intensity of the universe, why did you not contact with foreigners? Some scholars have been asked for a long time.

Where is everyone? Enrico Ferry asked other physicists during lunch in 1950.

This dilemma was called a Fermi paradox, which mainly indicates this, with enough time, “Each type of species must end outside the planet on its own Elon MuskJason Wright, director of the intelligence center outside the land at Pennsylvania State University, told AFP that the next star will be the next.

“Great Silence”

The fact that life outside the planet is not yet known “The secret of great silence.”

At least 75 virtual solutions were suggested to Fermi’s paradox, According to a book published in 2015.

It is possible that humanity has not yet discovered a strange life because it does not exist.

But many scientists consider this unlikely.

around87 % of respondents in a recent survey of nature astronomy magazine believe that there is at least an external life. More than 67 % believe that there are smart civilizations.

It is also possible that foreigners already exist without discovering or hiding them.

It may be very difficult to cross the space between the stars, as the distances are very wide and the necessary resources.

An animal garden, planet, or a dark forest?

Another theory is that there is a “great candidate” that would prevent life from producing or exceeding a specific development situation.

For example, once civilization dominates technology to travel to space, it can tend to self -amplification or exhaust the natural resources of its planet.

There are more speculative theoriesAs the “zoo” hypothesis, according to what it was outside the advanced technological land, she chose to leave humans alone to monitor them from afar.

Or such a “planetarium”, which indicates that foreigners create an illusion that makes the space look empty for burglary.

On the other hand, there is the “dark forests” hypothesis, which in its name condemns to the second book of the science fiction series “The problem of the three bodies”By Chinese writer Sixen Liu.

This solution indicates that the universe is a dark forest in which no one wants to reveal its existence so that others do not destroy it.

There are other hypotheses, according to which foreigners prefer to “bypass” another plane for existence, which compares some to virtual reality.

But there is a big problem with a large number of these “Solutions”, Jason Wright, from Pennsylvania State University.

All of them start from the principle that all virtual types of civilizations outside the planet behave in the same way and forever.
