NASA The scientists explained in A new leaf Because they think it’s possible we haven’t encountered intelligent extraterrestrial life — and it’s heartbreaking.
They argue that all intelligent life probably self-destructed before reaching a sufficiently complex point in evolution to support such an encounter. They believe the same fate will likely await humans unless we act.
The “Great Filter” theory – as in the “liquidation” of various life forms – holds that other, possibly different, civilizations existed during the lifetime of the universe. But all destroyed themselves before they could make contact with Earth, the paper noted,Avoiding the “Great Filter”: Extraterrestrial Life and Humanity’s Future in the Universe. “
Scientists fear that all forms of intelligent life, such as humans, suffer from profound imbalances that could “rapidly escalate into the Great Filter,” they wrote.
But there’s still a modicum of hope for humans, provided we can learn and take steps to avoid our own extinction, notes the paper by a team of researchers at NASA’s Jet Propulsion Laboratory in Southern California.
“The key for humanity to successfully pass such a global filter is … identification [destructive] “The qualities in ourselves are pre-neutralized,” write astrophysicist Jonathan Jiang and colleagues in the paper published online Oct. 23.

The authors argue that anything that seems likely to wipe out humans would also threaten intelligent life on other planets. The authors noted that potential culprits — which could be affected by humans or other intelligent life — include nuclear war, the pandemic, climate change, and runaway artificial intelligence.
The trick, the biggest challenge of all, is to work together to survive, the researchers said.
“History has shown that competition between species and, above all, cooperation, have led us to the highest peaks of invention. Yet we perpetuate concepts that seem antithetical to long-term sustainable growth: racism, genocide, injustice and vandalism,” the book warns.
