A recent study has revealed that there may be dozens of civilizations in the Milky Way galaxy waiting to be found, which sheds light on the fate of human life on earth.
According to various British and American media, a research paper published in the journal Astrophysics suggested that other planets could be home to alien life, assuming that life develops on those planets in a manner similar to how they evolve on Earth, which could be home to similar virtual biodevelopment.
"There must be dozens of active civilizations in our galaxy, assuming that intelligent life takes 5 billion years to form on other planets as on Earth," said Christopher Conselice , a professor at the University of Nottingham.
"The idea is to look at evolution, but on a cosmic scale, by relying on calculations called bio-bioniccopic copernicus," he said.
The calculations of the Bionics limit come in two forms: a strong and a weak limit, the British newspaper The Independent reported.
The calculations of the weak limit indicate that intelligent life is formed on a planet at any time after 5 billion years. The calculations of the strong limit indicate that intelligent life is formed after 4.5 billion and 5 billion years.
The new research used strong limit calculations on the assumption that these new civilizations would need to evolve in mineral-rich environments. This is because human life has evolved near a mineral-rich environment.
Previous research from 2012 suggests that there is the appropriate "minimum star metal" required to form planets similar to Earth.
The researchers relied on those assumptions about planets where life or intelligent civilization might be formed in order to figure out how many planets in the Milky Way galaxy could be able to meet those vital conditions.
The discovery of any civilizations in our galaxy depends strongly on the extent to which we can capture signals sent in space, through signals transmitted over radio waves and satellites.
If these intelligent civilizations can continue like human civilization on earth, which has been sending signals over the past century, it can be estimated that there are some 36 intelligent civilizations continuing on other planets in the Milky Way.
If the signaling is to be transmitted as it is currently being done, interaction with those civilizations will be difficult, especially since the average distance to any possible civilization will be about 17,000 light years, making communication extremely difficult.
The other scenario is that the intelligent life of the Milky Way is life on Earth, that civilizations on other planets disappear before we can detect them, and that the prospects for long-term survival on this planet are lower than we think.
"Our new study indicates that the search for intelligent civilizations outside the Earth not only reveals the existence of how life forms on other planets, but also gives us clues as to how long our civilization will last before its extinction," says Conselice.
He added: "If we find that intelligent life on other planets is common, then this would reveal that our civilization could survive longer and for hundreds of years, and if we cannot find active civilizations on other planets in the Milky Way, then this is a bad sign." How long will human life last? ”
And Conselice pointed out that by searching for any intelligent life on other planets, even if we do not find one, we will discover something about the future and destiny of human life on Earth.
This study is not the first to indicate the evolution of smart life on other planets in the Milky Way.
Scientists have found a possible habitable planet called "Proxima B" that orbits the star Proxima Centauri, about 4.2 light years from the sun.
This planet receives quantities of star energy similar to that the planet receives from the sun.
If liquid physical forms are found, this means that the planet can be a habitat for smart life.
However, the researchers pointed out that there are many things that must be done to verify this matter, such as checking for the presence of atmosphere or chemicals that could support life on the face of the planet.
