Researchers at NASA’s Jet Propulsion Laboratory, California Institute of Technology, and Santiago High School who updated the 1961 Drake Equation, written by Dr. Frank Drake to estimate the number of active and communicative extraterrestrial civilizations in the Milky Way, reports the Daily Mail.
According to their study, extraterrestrials may have emerged some eight billion years after the formation of our galaxy.
The team included the idea that advances in science and technology inevitably lead to the destruction of civilizations, and that while humans have yet to make contact outside of our planet, scientists believe they have discovered Why. “If intelligent life is susceptible to self-annihilation, it is not surprising that there is little or no intelligent life elsewhere,” the study read.
The researchers also note that while there is intelligent life elsewhere in the galaxy, it is “still too young to be observed by us” and too far from Earth to identify.
