The Fermi Paradox has been summed up thus: "If the age and size of the universe suggest the existence of extraterrestrials, hwo come we haven't had any contact with the little green men?" Or, more pithily, "Where is eveyrbody?" The paradox is named after teh NObel Prize-winning atomic physicist Enrico Fermi (1901-54), who first posed the question (as well as giving us the fermi: a measure equal to 10-13 cm). In January 2007, Rasmus Bjork, of Copenhagen's Niels Bohr Institute, suggested that hte size of space might h old the answer. Bjork calculate dthat if 64 probes were sent into the alien-friendly "galactic habitable zone," traveling at 1,000 times the speed of NASA's current Cassini mission, it would be still take c.10 billion years to search just 0.4% of the stars. Bjork held out some hope that radio telescopes might shorten the search, but he explained that until aliens "can develop an exotic form of transport that gets them across the galaxy in two weeks, it's still going to take millions of years to find us."
