As far as we know, Earth is the only place in the Universe where life has arisen, let alone developed an intelligent civilization.
This baffling contradiction is known as the Fermi Paradox, first described in 1950 by the physicist Enrico Fermi.
Scientists have been trying to resolve this mystery for decades, listening for radio signals from other worlds. Weve only sampled a fraction of the radio spectrum, and so far, we havent detected anything that could be a signal from an intelligent species.
How can we explain this?

talking on their obamaphones.
We don’t want to find intelligent life. We need life we can eat.
Rudimentary creatures of blood and flesh, you touch my mind, fumbling in ignorance, incapable of understanding. There is a realm of existence so far beyond your own you cannot even imagine it. I am beyond your comprehension. I am Sovereign.
Reaper? A label created by the Protheans to give voice to their destruction. In the end, what they chose to call us is irrelevant. We simply... are.
Organic life is nothing but a genetic mutation, an accident. Your lives are measured in years and decades. You wither and die. We are eternal, the pinnacle of evolution and existence. Before us, you are nothing. Your extinction is inevitable. We are the end of everything.
Confidence born of ignorance. The cycle cannot be broken. The pattern has repeated itself more times than you can fathom. Organic civilizations rise, evolve, advance, and at the apex of their glory they are extinguished. The Protheans were not the first. They did not create the Citadel. They did not forge the mass relays. They mere found them - the legacy of my kind. Your civilization is based on the technology of the mass relays. Our technology. By using it, your civilization develops along the paths we desire.
We impose order on the chaos of organic life. You exist because we allow it, and you will end because we demand it. My kind transcends your very understanding.
We are each a nation - independent, free of all weakness. You cannot grasp the nature of our existence. We have no beginning. We have no end. We are infinite. Millions of years after your civilization has been eradicated and forgotten, we will endure.
We are legion. The time of our return is coming. Our numbers will darken the sky of every world. You cannot escape your doom.
They are waiting for extraterrestrial amnesty. :-)
Texas, New Mexico, Arizona, California, Montgomery County, MD, Oregon, Washington State and Colorado, for a starter.
The Votans are expected to arrive sometime this year.
If the closest planet with life is a million light years away, it's just the same as if we were alone in the universe.
11,000,000 aliens in the United States, including at least one in our White House. Why would we want to find more - so McCain can invite them to our country at our expense?
They’re in sanctuary solar systems.
If they are more advanced than us, maybe they stopped using radios a long time ago. If they are less advanced, they don’t have radios yet. Or maybe the aliens communicate some other way.
Still appearing to two-toothed Mississippi and Louisana swamp drellers. If ETs are so smart what is their navagation so screwed?
In the beginning ...
They’re sitting right next to you in the 5th Dimension
Don’t you know that you are a shooting star ...
(our neighbors died.)
They don’t use radio spectrum. HD only.
most people cannot grasp the enormity of our galaxy let alone the universe. Mathematics is important here, if "tricky numbers" make sense, you're Polly not sitting out side on a cold night waiting for visitors to sneak down to make crop circles.
over the last 50 years there have been many proposed answers to the Fermi paradox; my favorite is that no one would ever make the trip between stars unless “its” civilization developed three things; money, banks, and compound interest
If there were another civilized society in the universe, one has to question would they want to be found by us. Our history, of this planet, does not mimic civilization which is civilized.
Even our lighting is converting over to LED, and that will reduce visible frequencies even more. Eventually an advanced solar system wide civilization would build a roof over the whole place and even their central star would disappear.
A sufficiently active dyson sphere might glow in infrared but we'd think of it as a likely failed star!
Our local galaxy cluster has BILLIONS of what seem to be failed stars.
Sheriff Arpaio keeps on pointing one out, but others keep on insisting he’s a domestic humanoid.
maybe and maybe not ... is fun to speculate though, then again, one has to ask is Heaven a civilization?
That must be a different ship than the Illegal Votans, scheduled to arrive in Fall 2014.
We are probably not as intelligent as we would like to believe.
Or maybe we are first.
Ah, your Earth languages are so tricky!
...Usually found in the Home Depot system as asteroid belts.
ONLY two possible answers (if aliens do exist):
1. They couldn’t overcome their bureaucracy and it keeps them at a low technological level- or even led to their extermination.
2. They see our beauracracy and, naturally, quarantine us until we overcome it.
I never saw that picture of Madame Speaker... in the middle of one of her cosmetic procedures! Neat!
Don't understand it either. They should fit right in on either coast, since they're supposedly frail, skinny, and pale.
“A sufficiently active dyson sphere might glow in infrared but we’d think of it as a likely failed star!”
I read a sci-fi book that postulated that the reason red dwarfs are so common is that some actually much larger stars inside of dyson spheres. I suppose it would help with all the missing mass they talk about.
Carl Sagan wrote something in Cosmos that really blew my mind. He said there are roughly 10,000 stars visible on a clear night to the naked eye. A handful of sand holds roughly 10,000 grains. There are more stars in the universe than individual grains of sand on every beach and desert on the planet.
Yes, the universe is that big!
I have no doubt that uncountable other planets have life, even intelligent life. Many of them have probably mastered intergalactic space travel at sub-light speeds. They just don't know we're here. If they had telescopes that could detect made-made objects, geometric shapes and such, they wouldn't see them if they were more than 4,000 light years away. If they were looking for radio signals, that lowers it to about a mere 80 or so light years away.
Good points. Light speed communication is basically new to the people of our planet.
Spot on. Folks who ask where all the aliens are have no comprehension of the size of this universe.
To paraphrase Douglas Adams, they have about as as much understanding of space and time as a concussed bee.
We have had the ability to communicate electronically for only a few years. We assume that intelligent civilizations will last forever—but what if they don’t? What if they flower and then decay for all kinds of reasons. They may destroy themselves. They may degenerate due to ennui (reverse evolution). Or, as Arthur C. Clarke suggested, they may evolve to a higher plane that has no desire to communicate with physical beings.
Take your pick. It could be that the life a an intelligent civilization is anywhere from 50 to 10000 years. Potentially, a very short window. I find this the most likely explanation.
You left out golf.
"I myself have dreamed up a structure intermediate between Dyson spheres and planets. Build a ring 93 million miles in radius - one Earth orbit - around the sun. If we have the mass of Jupiter to work with, and if we make it a thousand miles wide, we get a thickness of about a thousand feet for the base.
And it has advantages. The Ringworld will be much sturdier than a Dyson sphere. We can spin it on its axis for gravity. A rotation speed of 770 m/s will give us a gravity of one Earth normal. We wouldn't even need to roof it over. Place walls one thousand miles high at each edge, facing the sun. Very little air will leak over the edges.
Lord knows the thing is roomy enough. With three million times the surface area of the Earth, it will be some time before anyone complains of the crowding."

Thank You for the LOL.
