In recent months several leading astrophysicists from NASA to Harvard have suggested aliens are not science fiction: that advanced and ancient technological civilizations may exist but be beyond our comprehension or ability to detect. Silvano P. Colombano at NASA’s Ames Research Center proposes that we may have missed signals when it comes to looking for UFOs.
“Our form of life and intelligence,” observes Colombano, “may just be a tiny first step in a continuing evolution that may well produce forms of intelligence that are far superior to ours and no longer based on carbon “machinery.”
In a similar vein, the director of Columbia University’s Astrobiology Center Caleb Scharf proposes that alien life could be so advanced it becomes indistinguishable from physics. While Harvard’s Avi Loeb suggests that the first-known interstellar visitor to our Solar System, Oumuamua, could be a probe sent by an alien space-faring civilization, and that the scientific community should be more willing to acknowledge and embrace uncertainty.
