Meeting 75 - March 2019
The Firmi Paradox ~ Ronald Anderson
Since the age of the Universe is so great and its size so vast, with hundreds of billions of stars in the Milky Way alone, many of which have their own planetary systems, then unless the Earth is remarkably atypical in having the conditions to harbour life, the Universe should be teeming with it, including intelligent civilisations, many of which would have the technology required for space travel and would have visited Earth by now.
So, where is everybody? The query posed by Enrico Fermi in 1950.
