The Long Term Perspectives of Nuclear Energy: Revisiting the Fermi Paradox
Post revised and readapted from “The Hubbert hurdle: revisiting the Fermi Paradox” — Published on “Cassandra’s Legacy” in May 2011
The discovery of thousands of extrasolar planets is revolutionizing our views of the universe. It seems clear that planets are common around stars and, with about 100 billion stars in our galaxy, organic life cannot be that rare. Of course, “organic life” doesn’t mean “intelligent life,” and the latter doesn’t mean “technologically advanced civilization.” But, with so many planets, the galaxy may well be teeming with alien civilizations, some of them technologically as advanced as us, possibly much more.
The next step in this line of reasoning is called the “Fermi Paradox,” said to have been proposed for the first time by the physicist Enrico Fermi in the 1950s. It goes as, “if aliens exist, why aren’t they here?”…
