Avi Loeb
player
A Harvard astronomer took the search for alien technology mainstream, and drew fierce scientific pushback for it.
Who they are
Avi Loeb, a Harvard astrophysicist who founded the Galileo Project in 2021.
What they do
The engine treats him as a popular-science contributor to big questions about the cosmos, whose methods are solid but whose conclusions are disputed.
How it works
He set up the Galileo Project to systematically hunt for signs of alien technology in our solar system, and argued that the 2017 interstellar object 'Oumuamua sped up in a way that could hint at a technological origin.
Why it matters
His project's methods are careful engineering, but his conclusions remain contested among astrobiologists, so the engine keeps his claims at arm's length rather than treating them as settled.
The engine's record — word for word
Harvard astrophysicist; founded Galileo Project (2021) for systematic technosignature search within the solar system. Argued 'Oumuamua (2017 interstellar object) showed non-gravitational acceleration consistent with possible technological origin. Engine treatment: Tier-3 cosmological-Apex contributor — popular-science profile; Galileo Project methodology is engineering, but conclusions remain contested in academic astrobiology.
