New research: There are at least 36 intelligent civilizations in the galaxy

Research published in the prestigious American astrophysics journal suggests that Earth is just one of many regions with intelligent life in the galaxy.

Research published in the prestigious American astrophysics journal suggests that Earth is just one of many regions with intelligent life in the galaxy.

CNN noted scientists from Nottingham University (UK) based on the "biological Corpenic Limit" to complete the study.

According to Professor Christopher Conselice, who led the research, the team used assumptions and limitations on the development of life on the planet, similar to the Earth, thereby analyzing the possibility of intelligent civilization. in the galaxy.

"When conditions become available, life will form. It is possible to assume this is similar to that on Earth," GS Conselice said.

Associate Professor Tom Westby - co-author of the study - said that the basic condition for creating intelligent civilization is time. The team estimates that planets that have a high-tech civilization like the Earth must now have a lifespan of between 4.5 and 5.5 billion years.

At the same time, the planet is influenced by a metal-rich back like the Sun. Especially with intelligent civilization, the planet needs connections to the universe through radio and satellite radiation .

Some of the other constraints the group makes in the equations include the age, the star's support ability; history begin; whether the planet lies in the region of life or not (suitable distance, neither too hot nor too cold, liquid water on the surface .)

After completing the equations based on the above limits, the team estimates that there are currently about 36 intelligent civilizations operating in the galaxy.

However, according to Professor Christopher Conselice, these civilizations can be as far as 17,000 light years from Earth, so it is still very difficult to connect with each other right now. This leads to another difficult problem of determining the specific distance and time of these vital signs compared to the Earth.

Conselice further analyzed: within the limits of research, the factor within the habitable zone is very important. In addition, the planet must orbit a stable star for billions of years.

"Studying intelligent civilizations in outer space not only lifts the curtain on new life, but it can also elicit how long civil society answers can last , " said Professor Conselice.
