At any practical pace of interstellar travel, the galaxy can be completely colonized in just a few tens of millions of years. According to this line of thinking, the Earth should have already been colonized, or at least visited
there is indeed the possibility for BILLIONS of advanced technological civilizations to be extant, thriving and rampant all over the universe.
On the other hand, the Universe is VAST. The very same statistics that give positive indication of probability for life elsewhere is the very same thing that makes it almost impossibly improbable that any single intelligent technologically advanced culture anywhere in the universe at any time frame (important) will encounter any other culture.

Honestly, may be my bias on this, but I think that paradox actually argues in favor of visitation and covert existence on Earth.
Seeing how if Earth is typical, then there would be a high likelihood of galactic civilization. And it just doesn't stand to reason that Earth is this exceptional. I'd say a decent case could be made from this paradox that aliens may indeed have visited Earth.
I think it is more likely that a superior civilization exists and hides than there being no other analogous civilizations in the universe.
The Fermi Paradox Simplified The Fermi Paradox was first stated by Enrico Fermi in 1950 during a lunch time conversation. Fermi, a certified genius, used some straight forward math to show that if technological civilizations were common and moderately long-lived, then the galaxy ought to be fully inhabited. The vast distances of interstellar space should not be a significant barrier to any such civilization --assuming exponential population growth and plausible technology. "Contact" should thus be completely inevitable; we ought to find unavoidable evidence of "little green men" all about us. Our Search for Extraterrestrial Intelligence (SETI) should have been quickly successful. We don't. It hasn't been. That's the paradox.

What's your problem bro? You're the one leaving higher brain functions out of your thinking by insulting and generalizing a group of people based on your own emotional need to be correct.
I went off the quote you provided...If the basic theory is that common intelligent life throughout the universe would mean a colonized galaxy, and Earth seems not to be colonized by a superior species, there must not be intelligent life...then I stand by my point.
It is more likely colonization has indeed happened with us being unaware about it, then it is likely that Earth is home to the only intelligent life in the universe.
But sure, I'll look into the theory a little more.

The problem with humans attempts at detection is our methods are so....human. We're applying assumptions about life and intelligence entirely based on humanity and Earth. These are probably extremely weak assumptions. Radio communication is an example.
The reality is that our universe is so big and unknown, that speculation is every bit as valuable as verification. And there are too many possibilities to really discount anything.

Vid's not working...and I'll admit it is an interesting paradox that I hadn't read before, thank's for posting it..
'
But I can't come to the conclusion of nonexistence of aliens based on it. I can't come to the concrete conclusion of existence either, but I've always placed a very high probability there.
Have you concluded that intelligence life does not exist anywhere besides Earth?
Or are you,like me, just leaning hard in one direction.
ETA: A good explanation for there being no sign of life out there would be teleportational travel. Not outside the realm of possibility by any means.edit on 11/27/2012 by PatrickGarrow17 because: (no reason given)

Our understanding/knowledge of the universe is so undeveloped and minuscule- it is ignorant for one to say in fact what is and what isn't, what exists and what doesn't in such a case.

In Our yet 'exploration' of the universe, we have not even gone past our own sun (in fact we are still billions of miles away from it), something that we see everyday and revolve around, our understanding of the universe and knowledge of so is so undeveloped and minuscule- it is ignorant for one to say in fact what is and what isn't, what exists and what doesn't in such a case.

most people do not wish to open their minds to such a thing because the unknown scares the living hell out of them

To turn that on its head; there are too many possibilities for NO Aliens to account for anything.
Everywhere we've looked, so far, equals no life, not even microbes.

From a numerical standpoint, sure, there's possibility for aliens, but, from a physical standpoint, well, you may want to consider how deadly Gamma Rays, and other very high energy hazards, not to mention the cold vacuum of space, hazardous gravity wells like super massive stars, neutron stars, black holes, and all the giga-tons of super deadly dangerous hazards like little bits of rock travelling at relativistic speeds that could turn anything they impact into a beautiful blossom of nuclear equivalent blast, and then there's antimatter, plus any number of unknown hazards all over the universe.
Outside the comfort and safety of our warm little planetary bubble, it's a harsh deadly dangerous, not-friendly-at-all jungle of death dealing hazards.
