75 Solutions to the Fermi Paradox - New Space Economy

The Fermi Paradox presents a compelling contradiction: the vastness of the universe, filled with billions of stars and potentially habitable planets, suggests that extraterrestrial civilizations should be common. Yet, humanity has encountered no clear evidence of such life. This tension between high probability and apparent absence has inspired decades of scientific speculation, theoretical modeling, and philosophical inquiry.
