For as long as humans have looked to the night sky to divine meaning and a place in the universe, we have let our minds wander to thoughts of distant worlds populated by beings unlike ourselves. The ancient Greeks were the first Western thinkers to consider formally the possibility of an infinite universe housing an infinite number of civilizations. Much later, in the 16th century, the Copernican model of a heliocentric solar system opened the door to all sorts of extraterrestrial musings (once the Earth was no longer at the center of creation and was merely one body in a vast cloud of celestial objects, who was to say God hadn't set other life-sustaining worlds into motion?) While that line of thinking never sat well with the church, speculation about alien life kept pace with scientific inquiry up through the Enlightenment and on into the twentieth century.
But it wasn't until the close of the 1950s that anyone proposed a credible way to look for these distant, hypothetical neighbors. The space age had dawned, and science was anxious to know what lay in wait beyond the confines of our thin, insulating atmosphere. The Russians had, in 1957 and 1958, launched the first three Sputnik satellites into Earth orbit; the United States was poised to launch in 1960 the successful Pioneer 5 interplanetary probe out toward Venus. We were readying machines to travel farther than most of us could imagine, but in the context of the vast reaches of outer space, we would come no closer to unknown planetary systems than if we'd never left Earth at all.
Our only strategy was to hope intelligent life had taken root elsewhere and evolved well beyond our technological capabilities—to the point at which they could call us across the empty plains of space. Our challenge was to figure out which phone might be ringing and how exactly to pick it up. And so it was in mid-September of 1959 that two young physicists at Cornell University authored a two-page article in Nature magazine entitled "Searching for Interstellar Communications." With that, the modern search for extraterrestrial life was born, and life on Earth would never again be the same.
Launch the gallery to see how the search began and where it will take us next.

Why don't we start by looking for Intelligent life on our own planet first?
6 out of 6 people found this comment helpfulWell, if you think about it, there has to be SOMETHING out there. I mean it is space right? It just goes on and on and on. Be crazy to think we are it.

Just not enough data at this point. We really only have one data point, Earth.
You can't make extrapolations with one data point.
I like to think there is something out there though.

assuming the extraterrestrials really exist (and I believe they exist) assuming they are living now on their planets, assuming they have an (Earth-like or better) advanced technology, assuming they WANT to communicate with other species (that may be dangerous for them, like we could be...) assuming they use radio and/or light wavelenghts (rather than zero mass neutrinos or other, unknown, ways) to send their messages everywhere in our galaxy, assuming their planets are close enough to Earth to receive their signals, etc. etc. etc. the ONLY way to find them is to put one or more 10-100 times bigger than Earth's surface (or Hubble) optical and radio telescopes on the FAR side of the Moon
that's possible (and may give BIG scientific results) thanks to the ZERO atmosphere and ZERO radiowaves' pollution of the Moon's far side
unfortunately, a Lunar Telescope will remain just a DREAM for (at least) the next 100 years !!!
that, since, with the current (planned) ESAS vehicles and rockets, we'll have an INCREDIBLY POOR LUNAR CARGO:
the equivalent TOTAL mass of just ONE Space Shuttle by the end of 2080 !!!
everything is explained in this article:

0 out of 1 people found this comment helpfulI am almost certain that there is extraterrestrial life. But what are the chances that they are equally evolved or more evolved than us? Nearly none. Even that WE evolved this far is a miracle. And if we find alien life, would we even know that it is life? Or would it be so far from what we know as life that we would not recognize it as life? (e.g. an interdimensional cloudlike being that does not eat and has no home planet.)
I would be very excited if we found intelligent life on another planet, but right now, it seems like wishful thinking.
1 out of 2 people found this comment helpfulAs Pogo Possum once observed:.
"Some say there is other intelligent life in the universe, some others say we are the most intelligent and advanced creatures in the universe. Either way, it's a mighty sobering thought."
Considering that the building blocks for life "as we know it" have been found in many locations in space it seems likely that we are not alone.
And what can we say about Life "as we don't know it?" Not much.
1 out of 1 people found this comment helpfulAre we alone? Somebody has to be first. In a universe as young as ours could we be them?
0 out of 0 people found this comment helpfulIt will be awhile bfore we can have any meaningful communication even if we discover something. Whatever we discover would be years out of date because of the distances involved! As yet we know of no way to "fold space" or create worm-holes, so traversing such distances or getting signals across them, is, so far, impossible for us.
0 out of 0 people found this comment helpfulIt's a well known fact that Einstein denied the existence of black holes to his death bed. He said that their concept was to mind boggling to even contemplate.
However, that hasn't stopped the rest of society proving conclusively that they are there. Even though only math originally predicted black hole's existence, however, with the advent of technological development we've have been able to conclusively prove that they are there through indirect celestial observations.
Math, science and technology helps humanity see things that we ordinarily would not even know to think about let alone verify really being there.
In fact many science fiction oddities have fast become the main stay of our real-time modern day technology and communications, like cell phones performing much better than the original ideas of them presented on Star Trek.
So, why would it be that much harder to imagine that we already have the math, science and have even begun on the technological development of our very own Interplanetary / Interstellar vehicles.
This is certainly the most obvious conclusion one will come to after reading this PopSci article titled "Taming Gravity".
It's not hard to see the obvious implications of the technology being presented in this article. One would have to be pretty dense and/or extremely Conservative not to see it.
"Taming Gravity" is about our modern day attempts by Dr. Ning Li to apply the "Bose-Einstein condensate phenomena" to technology for the purpose of "Taming Gravity". It's called A/C Gravity and I invite you to read the article to see why it is called that and to leave your own comments as to what you see in the promise of Dr. Ning Li's research.
Suffice to say, that if Dr. Ning Li hasn't already been shut up by the US military, her last employment was with them in 2003, her research should yield the kind of brake through that so far has only found it's way onto SciFi studios.
It makes one think that our current attempts of even thinking that we're on the same wave length as civilizations having any amount of time beyond our current situation as kids playing in the sand box.
One can only imagine what Albert Einstein would think if he were alive today of all this childish hullabaloo resulting from his original discovery of Relativity.

I have had the idea that someone in the know would actually WANT to find other life out there in space!
If there were to be someone who reads these comments, that really cares, it would be amazing!
However;
I believe the scientists who are looking, are thinking in too narrow a field! They are using the assumption that all life requires O2.
Why does all life require O2? It doesn't! Look at life in the gas vents in the ocean! Thay have found life where it was previously believed to be impossible!
When the scientists decide to get off their high horses, and actually try looking for other options, they may find something!
For example: Instead of transmitting radio waves, Why not transmit light??? There is a narrow band of light that can not only be bright enough at a low power, but it would be able to bounce around like a ray of light shining in a pool of water!
Ideas make the world move! Or is that gravity?
S.E.T.I., could use their massive dish to transmit a message , using a beam of light!
Another option would be using a gas-hydrate.
Hey, but what do I know!
I come up with ideas for just about anything and everything.
I have invented a bunch of usefull things. However; Being extremely poor, prohibits me from being able to obtain any patents.
It's too slow when you're looking forward;

In my ACE Series I will write about alien technology that goes far beyond what people claim is alien technology. One of the items is the nuclear battery that will use a super-dense transuranic element that will cause the battery to tap the electromagnetic field of the earth and use it for power which means the battery will have an energy output greater than the energy it stores. If too many batteries are used they will draw so much energy from earth's fields that they could tear open a huge hole in our atmosphere and allow radiation from space to hit us.
Another item is a portable interdimensional portal device that can fold up into a device no larger than a pen so that it can be carried in your pocket. The controller will be a projector that appears when the portal is unfolded into a door-size device that is self-standing. Once you walk through it, the portal will also shift to the dimension you have entered. It will be the way humans and aliens shift between dimensions.
A third item will be the hyperlight speed element synthesizer. The way we make transuranic elements is wrong. That is why they last such a short while. The correct way to create a superdense transuranic element is by blending the particles with the element you want to build onto. With the particles being blended at hyperlight speed, they can be "set" better so that the new element becomes stable. Instead of just bombarding one element with another element and hoping a more massive element is produced, the entire element will be blended together with the particles to produced the desired element. It may require particle expansion similar to a nuclear explosion. But the blending and the field containment of the synthesizer will prevent the controlled explosion from going out of control. It will all happen in a split second. But the results will be massive transuranic elements that could double or triple the number of elements on the periodic table of elements.
I could go on. But I need to wirte the books first to see what is going to happen and to see what marvels are going to be revealed thanks the the ACE Program.
0 out of 1 people found this comment helpfulConsidering the countless numbers of galaxies similar in structure to ours, it simply can be assumed that intelligent life exists in profusion throughout the universe. However, the cosmic distances between stars with habitable planets make it improbable that civilizations ever will physically interact, or that comminication signals ever will be detected, or exchanged. Were it to become possible to find, evaluate and compare other civilizations however, it might be learned whether some intelligent life forms preserved their civilizations and their planets, while others like us followed a pattern of exhausting planetary resources, poisoning the environment, and dissolving into social disorder, lethal conflict, and famines.
0 out of 1 people found this comment helpfulI thought of an analogy to compare contact with extraterrestrial life to the old west contact of east to west coast. Back before the telegraph and electricity, there was no fast communication. In the old west, smoke signals and the pony express was used. After the telegraph, communication speed increased dramatically.
0 out of 0 people found this comment helpfulCurrently, all we are looking for are smoke signals from distants stars (radio transmissions that travel at c over light years) while relying on a pony express style means of communication (radio waves that travel at c for years to reach somewhere).
If there exists a high level of extraterrestrial intelligence, then they probably aren't going to use these forms of communication, that is if they are more highly advanced as us. They will be using some form of faster than light communication, which we wouldn't detect with our current radio receivers.
What we need is the space era version of the telegraph. Now it is probably more difficult to send messages faster than light than to receive messages faster than light. All we need to do, however, is to listen first to see if there is anything out there, so a receiver would work just fine.
What I propose we do is that someone out there with that knowledge start developing a receiver for faster than light communication first to see if there is anyone out there. If so, we could study the forms of transmission and get a jump start on a FTL Transmitter, which could ultimately lead to even higher technology elsewhere.
ok, to start, Research Operation Highjump. "Aliens", as we call them, have already been found here on Earth. They, started contacting our "World Leaders" back when we dropped those Atomic bombs on Hiroshima. They asked that we stop using them, that we're tampering with a power we're not ready for. Our leaders told them to screw, basically, and attacked them everytime they tried to make contact after that. These "aliens" have been living here on Earth for thousands of years. At some point, humans decided to banish them from our countries and they moved to the poles. These aliens would later be called Satan and his minions. Another type of alien created us through genetic enginneering using DNA from (obviously) the ape and DNA from either themselves or from the ETs that were eventually banished. They called themselves Aryans and looked very much human. Also research Sumer and Hopi religion with these things in mind.
1 out of 1 people found this comment helpfulWell, no one has ever counted the number of galaxies out there, (estimated at about 100 billion) or the number of stars in the average galaxy (also estimated at nearly the same), mathematical figures of probability would suggest that anyone who believes that we are the only intelligent life in the universe is incredibly naive.

0 out of 0 people found this comment helpfulHow do we reconcile the idea that we need to search the galaxy for aliens with the denial that aliens have visited earth? Why is there not an effort to communicate with the so called sightings (by supposedly reputable people) of ETs? If, in fact, there were aliens that crash landed on earth and were stashed away by the government and kept secret as reported by Army personnel and the media, why are we searching way out there for something that is supposedly stored in our backyard? Is there some reason that the goverment created the giant listening dishes while at the same time denying the existence of extra terrestrial visitors? Just wondering...
0 out of 0 people found this comment helpfulyou would have to be crazy to think that there isn't life
on other planets out there. explained by the following .
we are just one planet in our solar system, whitch is of 100's of thousands solar systems in our Galaxy..., Where there are 100's of Billions of other galaxy in the universe with there own 100's of thousands of Solar sytems.Each one have there own range of planets.
we cant be the only planet that has life, out of a 100.000 trillion other possible planets in the universe!
SIDE NOTE: The big bang theory by Gonzalo M.
yes there was the creation of our universe and we will
0 out of 0 people found this comment helpfulNEVER know HOW exatly it came to be!
There is one Huge part of the "big bang" that no one seems to talk about.. and im not talking about the God "particle" !!
Im talking about God himself. he created our know universe and beyond. Everything pefectly following his laws and rules that govern our world we live in. and all of the rules and laws that govern the universe that we just can't comprehend..!
from edmond, oklahoma
Though we have yet to find "Intelligent" life on other planets, we have found microbes on a planets moon... I cant remember which one or what planet but I think it was either one of Jupiters or Neptunes moons, and also on the surface of mars a rover found traces of organic life in the soil, unfortunently it can't be for sure until more samples are taken because it may have been cantamination that some how survived all that way to space? I dont think so.....
