formulated an equation to calculate the number of detectable extraterrestrial civilizations in our Milky Way. Rather than being a scientific principle, the equation was intended as a thought experiment that summarized the challenges SETI researchers faced. This became known as theThis is motivated by ongoing research into the origins of life on Earth and the preconditions that led to its emergence.
As noted, the Drake Equation was not intended as a tool for estimating the number of extraterrestrial intelligences but as a guide for how scientists should search for life in the Universe. The formula for the equation is:is the length of time that these civilizations would have to transmit their signals into space.
In their paper, the team calculated the fraction of ordinary matter that is converted into stars over the entire history of the Universe based on different Dark Energy densities. Stars are essential to life, creating heavier elements through nuclear fusion that allow for planet formation, biochemistry, and all life as we know it. Their model predicts that the most efficient density for star formation would be 27%, compared to 23% scientists have observed in our Universe.
These findings could have significant implications for cosmology and the ongoing debate about whether or not our Universe is “fine-tuned” for life. As Dr. Sorini explained in a Royal Astronomical Society
