According to scientists, there are more than 30 ex̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s on other worlds with which humanity may speak.
According to a research conducted by a group of specialists from the University of Nottingham in the United Kingdom, our galaxy has 36 a̳l̳i̳e̳n̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s. The investigation’s findings were published in the Astrophysical Journal.
The researchers, lead by astrophysics professor Christopher Conselice, came at this conclusion because they think intelligent life exists on other planets in the same manner it does on Earth.
“Our findings show that searching for a̳l̳i̳e̳n̳ intelligent c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s not only reveals knowledge about how life is formed, but also gives us indications about how long our c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳ will persist,” Conselice said.
Professor Conselice says, “Our new research suggests that searches for a̳l̳i̳e̳n̳ intelligent c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s not only disclose the existence of how life forms, but also give indicators of how long our own c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳ will persist.”
“Finding intelligent life in our Galaxy would be a positive sign for our own long-term survival; conversely, finding no active c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s in our Galaxy would be a terrible omen for our own long-term survival.” Even if we find nothing, we are determining our own fate and future by searching for a̳l̳i̳e̳n̳ intelligent life.”
The “Copernican principle,” which is based on a philosophical theory used in astronomy and posits that the Earth is not the only planet in the Universe where life may exist, was the starting point for astronomers.
Scientists also employed the Drake equation, which takes into account seven prerequisites for the emergence of intelligent life on another planet, including the star and a planet surrounding it with suitable circumstances for life.
Based on mathematical calculations, scientists estimate that there are around 36 technologically advanced c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s in the Milky Way.
The researchers also took into account the fact that developing sentient life on other planets would take at least 5 billion years, or about the same amount of time as it would on Earth.
As a result, astrophysicists believe our galaxy should include at least a few dozen functional intelligent c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s.
