::We do have pet ferrets. They are cute, It is unlikely that there is another source of pet ferrets in the galaxy.

:I've always found this to be terrible logic. In addition to sci-fi, we also broadcast news and documentaries. In addition to fictional triumphs, we also have real-life failures. We've broadcast that funding to NASA has been cut, and how he haven't been farther than the moon in what, 50 years? We have Mythbusters which is constantly debunking stupid stuff that humans believe, and also showing off the limits of our technology in a practical manner. We broadcast war, so they would be able to see just how deadly we actually are. Worst of all, we broadcast Fox News. I don't see aliens fearing us (if they're technologically advanced enough to spy on us without us seeing them), I see them wondering just what the Hell is going on here.

I think the problem is that traditional SETI methods are of dubious effectiveness at actually detecting radio transmissions from other civilizations due to the low initial power of said transmissions which then only get weaker as they propagate. Switch to our new optical methods of planet detection which have detected scores of planets in just a few years and the "paradox" might need to be reevaluated. Optical detection also makes it doubtful that any civilization would be able to effectively hide.

By the way, the Chinese sci-fi writer {{w|Liu Cixin}} has published a {{w|Three Body (science_fiction)|trilogy}} called "Three Body", focusing on this idea (he called it "dark forest"): what if all the visible civilizations have been destroyed? What if revealing your neighbor's location to the universe is similar to the MAD ({{w|Mutual assured destruction}}) situation? The English version should hit the market this year. --[[User:Ent|Ent]] ([[User talk:Ent|talk]]) 15:51, 4 June 2014 (UTC) | By the way, the Chinese sci-fi writer {{w|Liu Cixin}} has published a {{w|Three Body (science_fiction)|trilogy}} called "Three Body", focusing on this idea (he called it "dark forest"): what if all the visible civilizations have been destroyed?

This is very similar to a *lot* of SF out there. Pellegrino's "The Killing Star" is one good example (with R-bombing and the problems associated with it), but it's certainly not the only one. Listing some of these might be good. Listing the "Central Park at night" example from "The Killing Star" might be a reasonable addition.

− | The real reason seems clear to me: existence of other life forms in the universe is probabilistically certain, but universe is so huge (in space and time) that we have no hope of reaching it. Regarding "huge in time", for example Mars might have been like nowadays's earth one billion years ago with elaborate civilisations and yet we now struggle to find a trace of life{{Citation needed}}. Regarding "huge in space", no hope of reaching it or even have definite proof of discovery. Or, err. Well, I have not said "never", right ? But the point remains: universe is so huge that a lot of life can be "statistically everywhere" and we just can't see it because its density is too small. Which is another way to say: life most certainly exists on many planets (and other types of systems) yet the fact that we don't detect it easily means that the kind of life we are looking for never had a chance to propagate quickly enough | + | The real reason seems clear to me: existence of other life forms in the universe is probabilistically certain, but universe is so huge (in space and time) that we have no hope of reaching it.
