Robert H. Gray
In 2016, Gray published an article in "Scientific American" about the Fermi paradox, which claims that if extraterrestrials existed, we would see signs of them on Earth, because they would certainly colonize the galaxy by interstellar travel. Gray argues that the Fermi paradox, named after Nobel Prize-winning physicist Enrico Fermi, does not accurately represent Fermi's views. Gray states that Fermi questioned the feasibility of interstellar travel, but did not say definitively whether or not he thought extraterrestrials exist.
Manifold Trilogy
The second in the series, "Space", proposes the opposite: that life is endemic to the universe, and there is intelligence in nearly all possible places of the cosmos. The solution to the Fermi Paradox in this novel is that intelligent life is continually wiped out by cosmic disasters before it has time to spread too far.
