The Long Term Perspectives of Nuclear Energy: Revisiting the Fermi Paradox

This is a revisitation of a post that I published in 2011, with the title “The Hubbert hurdle: revisiting the Fermi Paradox Here, I am expanding the calculations of the previous post and emphasizing the relevance of the paradox on the availability of energy for planetary civilizations and, in particular on the possibility of developing controlled nuclear fusion. Of course, we can’t prove that nuclear fusion is impossible simply because we have not been invaded by aliens, so far. But these considerations give us a certain feeling on the orders of magnitude involved in the complex relationship between energy use and civilization. Despite the hype, nuclear energy of any kind may remain forever a marginal source of energy. (Above, an “Orion” spaceship, being pushed onward by the detonation of nuclear bombs at the back).
 

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?”…
