There are fewer planets than atoms in the universe? Wow, any more breaking news, oh revelator?
Fermi's paradox is only a paradox is you assume there should be other civilizations able to reach us. Why would someone assume that?
Quote:not assuming. but their pattern electromagnetic signals would be transmitted and detected.
You do understand just how many light years most possibly life supporting planets are away from us? And why assume all life evolves to include intelligent life? We are rather a rarity on earth.
As someone just pointed out in another thread, even if there are advanced star-faring species out there, when we train a telescope on distant galaxies, we see them as they were billions of years in the past.
The nearest observable star viewed through a telescope is 4.3 light years away.
The closest habitable earth-like planet is 493 light years away. That means we see it as it was 493 years in the past. Radio waves travel the same speed as light in a vacuum.
We didn't invent the radio until 1820, 194 years ago. That means our very first radio transmissions won't even reach the closest earth like planet for another 299 years, and we didn't start publicly broadcasting radio until 1910, so it will take 389 years for the first frequent radio broadcasts to reach the closest habitable earth like planet.
Here's the rest of the currently known exoplanets similar to earth: http://kepler.nasa.gov/Mission/discoveries/
Even if there is a well traveled federation of star-faring races, they probably wouldn't even know we're here, and won't for a long time to come. If they're even looking for radio signals.
