This documentary investigates one of the most controversial questions of the past hundred years... are we alone in the universe?

This is not one those films that claims to have conclusive proof, but rather a look at the serious science of the search for extraterrestrial life.

The search for extra-terrestrial life has been going for 50 years – but there’s been a recent breakthrough. Astronomers have discovered a new planet called Gliese 581 c.

It is the most Earth-like planet ever found. It orbits a star and may have habitats capable of supporting life. NASA hopes to find 50 more Earth-like planets by the end of the decade, all of which increases the chance that alien life has begun elsewhere.

  1. the chances of intelligent life out there is minimal to say the least, it was a freak of nature that enabled life on earth, we just have to accept that we are alone.

  2. We aren’t alone their every around us they have electrical currents flying around ,Everywhere .Get a IR CAM ya will see for ya self ,They are stalking every 1 of us ,Ya may think a plane flys past ,chopper fly past,They can make anything look like they want to .We are like a bunch of ants They can manipulate anything they want.

  4. as long as travelling many time faster than the speed of light is impossible, the answer is yes -we are alone!!! and noone will come to save us from ourselves, so....

  7. I have questions too. I do not however consider myself to be in to this particular theory nearly as deep as you.
    Please though, take this information; the US federal government has been actively involved (on record but publicly denying) in Extra Terrestrial evidence since the mid to late (19th century)1800's. In these alien circles, the US cavalry chased into a cave out west while pursuing bandits on horseback, and gray aliens with disks were first documented here, in the US. THIS IS INFO I READ THAT I FIGURED YOU MUST HAVE, CONSIDERING WHAT YOU SPEAK SO INTENSELY ON.
    ***I have no first hand knowledge, and I am not confirming or denying, I am simply telling you what many alien theorists have as "basic knowledge", this predates your , "50 year" time period by quite a bit.

  8. my guess is they dont want to contact because they can see what a$$holes we are

  9. smugg... searching is important. But i give you absolutely right. We people should really wake up, let some search on, but let the rest do what we want to do best. Is to care for the earth.. i just wish those few people who really dont want to work with us, should be gone!

  10. wow, humans are so anxious about discovering livable planets... they don't even know how to take care of this one...

  11. Has anyone ever noticed that every pyramid or ancient building system for our solar system is pointing and has been pointing to Orion's belt for thousands of years?
    Why don't we look their?
    I think our ancient ancestors are telling us something!

  12. Exciting isn't it. I wish we had some space discover race all over the world between countries that have space programs instead of wasting money on weapons that won't be used at all. Pitiful.

  13. I have always been a skeptical about the existence of aliens,however,paying atention to science and watching documentaries like these,you cant at least ignore the possibility.These days im convinced that it is very likely the existence of life elsewhere in the cosmos. Its almost sure there is. Thanks for posting this great documentary.

  15. Side note, we are just now starting to understand string thoery. Which is very strange stuff indeed. It says basically that all matter is created on these tiny vibrations. So light waves and radio waves are essentially bound by the exact physics that created us. What does this mean. It means we are all connected. Every single thing you see,feel,hear,taste and touch is a part of us. So its not so far fetched to think that an alien civilization millions or billions of years more advanced than our own, would have vastly more knowledge of this. And in there understanding, would know how to manipulate these tiny strings for anything they needed to. Thoughts themselves are mearly energy waves transmitted between your brain cells. So perhaps they dont need technology at all to communicate and they simply use there thoughts. How do we detect that?

  16. I think its ludacris and massively egocentric to assume we are alone. Billions of stars in our galaxy with billions of galaxies around it. That leaves an astronomicaly large number of stars to have orbiting planets ,each with the possibility of life!

    Depends mostly on your view of the world I suppose. How do you see your god. If you believe in the father universe version of god(which I do), rather than the image that he sits on a throne in the sky! Then its easy to understand the possibility of life elsewhere. My own understanding of god is that he was created during the bigbang ,as a single atom. Then he created 2 more atoms in his own image and made the first cell, then they in turn combined to make 8 pairs resulting in the first protein and so on.The dogans believed this and many more ancient civilizations understood it as well,why cant we? This is what I mean when I say until science and religion come together as 1 coherent study, we will never rediscover god. I feel strongly god is in all of us, we are mearly a vessel for him to explore the physical plane. In a sense we are all gods.

    They are here now, theyve been here for thousands of years. If you feel as I do, then you kinda begin to understand ,they are here to help us mature and develop. I feel strongly they came in masses around 1947 for no other reason that the atomic bomb. Killing each other is one thing, but splitting the atom (which I consider god in a sense) is the worst thing we could have ever done. Well see what happens in 2012, Im not going with the end of the world scenario. I think in some way we will be awakened to something. Maybe it has to do with the 1999 seattle incident when people all over the world stood together and said WE HAVE HAD ENOUGH. Thats the first time in recorded history that people from all over got to together for a common goal, Peace. This is an important time for us all and we need to learn the lesson those people taught us.

  17. I for one am sure that we are not alone in the universe. If we are then we should be very humbled.

  18. um...guys...radio signals ARE light. Just a spectrum of light that we cant see, because it isn't necessary for our survival to see them. in fact it would probably be fairly distracting.

  20. I think the point is that people are looking for life based on what we know is 100% fact. That is a carbon based life that communicates using one of the fastest traveling and easily generated forms of communication.

    Im sure alot of people out there would like to look for something more exotic but it seems a waste of time. I mean I could go butterfly watching on the north pole... and I might even find one. But it is NOT a good bet.

    Everyone talks about other technology. I would like to know what other kind of technology we should be trying to detect and exactly how it is detected. Don't forget little things like the fact that our power grid creates radio waves, even the ignition system in your car creates radio waves. So its not exactly a search for "communications", its a search for any kind of technology.

  21. Masharaki - agreed.

    Our physical forms have evolved, adapting to this planet. On other planets physical forms also evolve and adapt to the conditions of those planets.

    There is no reason to suppose that what we call the human form is unique to planet Earth and there is no reason to suppose that people have to have the same physical forms which we currently have.

    Um ... observing that the physical form which we currently use here is perfectly designed for the riding of motorcyles it is obvious that someone was thinking ahead >grin<

  22. @Raymond i admire your No 3 point on 'material form' .The scientist are making a serious kind of error if they approach this issue on assumption of our technological advancement,if there are other forms of life out there do is it mean then another world might be within this like when we have waves and it cant collide with this one?
    On the other hand it might be possible there are other hospitable worlds exactly like this one with say monkeys are superior and humans not realy developed like us or our lvel but below animals hehehehe

  23. Too many assumptions ...

    1. "Earth-like planet" - why assume an Earth-like planet is necessary?

    2. "Radio Signals" - Why assume communications would be via radio signals?

    3. And the biggest assumption is the Life requires a materil form (at least, as we understand 'material form') to be expressed and experienced.

    These, imo, are invalid assumptions.
    They could usefully think outside the box created by these limiting assumptions.
