Fermi Paradox and Its Explanations: Rare Earth, the Great Filter, and the Dark Forest

To the point

The Fermi paradox asks why we see no signs of intelligent life in a vast universe, and scientists such as Enrico Fermi, Frank Drake, Michael Hart, Frank Tipler, Peter Ward, Donald Brownlee, Liu Cixin, John Ball, and Nikolai Kardashev offer explanations like Rare Earth, the Great Filter, the Dark Forest, and the Zoo hypothesis, with exoplanet studies and the James Webb Space Telescope helping test which idea might be correct.
