In February 2020, four distinguished astrophysicists —Jonathan Carroll-Nellenback, Adam Frank, Jason Wright, Caleb Scharf— suggested that Earth may have remained unvisited by space-faring civilizations all the while existing in a galaxy of interstellar civilizations seeded by moving stars that spread alien life, offering a solution to the perplexing Fermi paradox. They concluded that a planet-hopping civilization could populate the Milky Way in as little as 650,000 years.
