On June 15th a new study published in the Astrophysical Journal by the University of Nottingham in the United Kingdom suggested that there may be 36 active intellectual civilizations in the entire Milky Way. The researchers hypothesized that intelligent life evolved on other planets in a similar way to Earth, leading to the existence of other extraterrestrial civilizations in our galaxy.
Christopher Conselice, a professor at the University of Nottingham, said: “Assuming that, like Earth, intelligent life takes 5 billion years to form on other planets, there should be at least a few dozen active civilizations in the banking system.” “
This calculation is based on two limits of astrobiology Copernicus: intelligent life, which took less than 5 billion years to form, similar to the human civilization that formed 4.5 billion years after Earth;
The number of civilizations depends largely on the amount of time they send existing signals to space, such as satellite or television radio transmissions, the researchers say. If other intelligent civilizations can continue to be 100 years old, and calculated, there will be about 36 intelligent civilizations throughout the Milky Way.
However, the average distance to these civilizations is 17,000 light-years, which makes it very difficult to detect and communicate with our current technology.
The researchers point out that the search for extraterrestrial intelligent civilization not only reveals the way life forms exist, but also provides us with clues as to how long human civilization will last, allowing humans to understand their own destiny and future.
