Thanks for sharing Duke!

There have also been other hypothesis, another major one is the fact that the reason we have never met aliens is that advanced civilizations end up destroying themselves before they manage to travel interstellar. If this theory is true, then we may never make it to the nearest star and are stuck on Earth :(

That article is just someone making up a possible explanation, it sounds like total BS to me, the universe couldn't be so poorly designed. I am convinced there are alien civilizations and that they even visit earth. We are wasting time looking for radio signals, they are either too far away or they don't use radio anymore.

I agree, isn't any more conclusive than any other theory put forward by anyone else. We've known about habitable zones and such for a good while too. Just too many planets out there for just us to be random chance.

That said - what do you suggest we use to look for intelligent life in the universe if not radio waves? ;)

That's a good question, probably some technology we haven't discovered yet. Not much good that will do us. We can't use a technology we don't have yet but there may be something we can do. If there is an advanced civilization with billions of people, we may be able to detect use of power systems or weapons tests. I know there are gamma ray bursts all over the place, how about we build more gamma ray telescopes and find a star that has frequent small gamma ray bursts or constant abnormal gamma ray emissions and then take a close look at that star every way we can. I don't really expect this would work either but it's worth a try. I think we will just have to wait awhile until we can do better.

I agree what Pi R Squared is saying .
aliens don't use radio signals since aliens are more advance
the human race has advanced so fast since the UFO crash in 1970s
:yh: look 25y ago and what is happen in this century

Earth has not been broadcasting into space very long on a cosmic scale. only a little over 100 years. this means for other beings to recieve them they must be within 100 light years, and if they reply, we wont hear for 100 years. that is how it will be unless we discover a faster than light way to communicate. know how many possible habitable planets are within 100 light years? probably virtually none

Crazy theory here. What if intelligent species have a tendency to destroy themselves when they reach some kind of technological achievement? Maybe they're experimenting with warp drives, or some kind of teleportation tech and create a black hole(or some other cataclysmic event) destroying their worlds?

Other theories
-They don't communicate with radio waves(already mentioned)
-The evolution of intelligence is the exception rather than the rule. Without an asteroid hitting the Earth and shaking things up, there would probably still be giant dumb reptiles running around killing each other.
-Interstellar travel simply isn't possible in a practical sense. Without warp drives good luck actually getting anywhere fast.

Crazier theories:
-Aliens are out there and just don't want us to know about them. They might (understandably) think our species isn't ready yet to join the 'galactic union' or whatever.
-Our government knows about aliens and hides it from the public.

Craziest theory: We're all simulations in the supercomputer of a super advanced society. They're simulating the evolution of intelligent life.

-Other random ideas.
-The existence of life is extraordinarily special and life has never occurred anywhere else(or in very few places in the universe). For all we know the nearest intelligent aliens might be in another galaxy.
-Religious people are right, God created life here and there are no aliens.

The Fermi Paradox (aka "Where is everybody") is about the absence of evidence for extraterrestrial intelligence. Copied from the linked Wikipedia site:

5 Hypothetical explanations for the paradox
5.1 Extraterrestrial life is rare or non-existent
5.2 No other intelligent species have arisen
5.3 Intelligent alien species lack advanced technology
5.4 It is the nature of intelligent life to destroy itself
5.5 It is the nature of intelligent life to destroy others
5.6 Periodic extinction by natural events
5.7 Inflation hypothesis and the youngness argument
5.8 Intelligent civilizations are too far apart in space or time
5.9 It is too expensive to spread physically throughout the galaxy
5.10 Human beings have not existed long enough
5.11 Humans are not listening properly
5.12 Civilizations broadcast detectable radio signals only for a brief period of time
5.13 They tend to isolate themselves
5.14 They are too alien
5.15 Everyone is listening, no one is transmitting
5.16 Earth is deliberately not contacted
5.17 Earth is purposely isolated (planetarium hypothesis)
5.18 It is dangerous to communicate
5.19 They are here undetected
5.20 They are here unacknowledged

I like the one (I read somewhere) that says eventually they figure out how to jump to another, better 'dimension' if you will, which is why they never come here. It's used to explain reported sightings where they appear then disappear (i.e. not with a cloaking device per se that makes them undetectable/unobservable but still 'here'). Eventually, if we don't annihilate ourselves, the theory goes we too will discover how to do that.
