According to the British newspaper “Daily Mail”, the statement comes from researchers at NASA’s Jet Propulsion Laboratory, California Institute of Technology and Santiago High School who used an updated version of the equation to calculate potential existence. intelligent life, and extraterrestrials may have appeared about eight billion years after our galaxy was formed. .
Perhaps with these results, the team included the idea that advances in science and technology inevitably lead to the destruction of civilizations, and they stated in the study: “If intelligent life is likely to destroy itself, it’s no surprise that intelligent life is in little or no other place.
The researchers also noted that if intelligent life were to exist elsewhere in the galaxy, they were still too young to be noticed and too far from Earth to be recognized.
In this study, the team updated the 1961 Drake Equation, which Dr. Frank Drake wrote to estimate the number of active extraterrestrial civilizations in the Milky Way.
However, according to the new article, the old version does not take into account the stellar properties evolving on our galaxy such as the discoveries of supernovae and exoplanets.
The team also looked at the likelihood of living in a prebiotic state, the different possible time scales of biological evolution, and the potential for self-annihilation of complex life.
“Using our model, if we assess the complexity of life in the Milky Way on a specific timescale, we can get a better understanding of the origins of the life hypothesis and the rare earth hypothesis,” says the article.
The paper also takes into account the possibility of self-annihilation, which researchers have ignored in the past.
