Pirilao Posted January 9, 2006 Share Posted January 9, 2006 The search for new worlds ESA's mission: to discover new worlds outside of our Solar System, to help answer the ultimate question; are we alone in the universe? Research goes on during and after Cassini/Huygens' exploration of Saturn with a planned new mission, Darwin, seeking the origins of life. Everything started with the Big Bang and 15 billion years later we are starting to understand as the universe really functions. Currently the scientists are rethink very radically the questions on the key of our existence: - Because we are here? - Of where we came? - We are alone in the universe? The researchers are making discovered surprising, as the existence of the primordial blocks of the life in the universe. We are knowing world beyond our solar system for the first time, all indicating the most surprising of all conclusions, of that we can be foreign in our proper planet. We are dust of stars?

Ide Jima Posted January 9, 2006 Share Posted January 9, 2006 The chances of there being extra terrestrial intelligent life forms are incredibely low. The requirements for life are so precise that only about a dozen planets could even fit the criteria - and then the chances of life coming into existence on these planets? Very low. Link to comment

Europa Posted January 9, 2006 Share Posted January 9, 2006 Well, don't be shocked, but I do believe extraterrestrial life forms could excist. I once said that in at school, years ago, and they looked at me like I came from Mars or something. However, I believe there is a change life can excist on other planets, which doesn't necessaraly mean intelligent life. I'm talking about bacteria, micro organsims and stuff like that, not about the "one-eyed green aliens coming over here in their flying saucers abducting people" which are typically associated with the term "alien". The Universe excist of billions of galaxies, containing trillions of stars. One of those galaxies is the Milky Way, and one of those millions of stars in it is our Sun, which supports our solar system. Even if the chances are small, I believe there might be a realistic chance life has developed somewhere out there.. Link to comment
Ylania Posted January 9, 2006 Share Posted January 9, 2006 Does life exist on other planets? I can see the possibility, but whether there actually is life out there, we don't yet know. So I'm sticking to my answer of "maybe". Hm... I'd like to try an experiment in thought. I'll explain later if I get a few responses from this. Now, imagine the world sometime in the future, when we finally manage interstellar travel pretty nicely. One day, we manage to chance upon a planet with intelligent lifeforms. How would we interact with them, if they had the same level of intelligence and technological developments as us? What if they were less developed? More developed? Link to comment
Scipii Posted January 9, 2006 Share Posted January 9, 2006 There is life on Earth so why not elsewhere? Link to comment
Ide Jima Posted January 9, 2006 Share Posted January 9, 2006 Depends what sort of conditions that life has evolved for, though, doesn't it? Any kind of life needs precise conditions to function, and for this life form to actually become significant the margin in which it could exist would be tiny. And like EE says, if life does exist, it is almost infinitely more likely to be single celled organisms. Link to comment
Europa Posted January 9, 2006 Share Posted January 9, 2006 Also you have to keep in account time and space are relative concepts.. Given the fact that the Universe is some billions of years old, and humans only appeared on Earth some hundred thousands of years ago, while most of the major scientific discoveries and technical inventions were only developed in the past couple of hundred years; electricity, machines, ships, cars, trains, airplanes, radio-signals, rockets, satellites,... It could very well be that there was intelligent life, or maybe even a civilisation if you will, on some planet at the other end of the Milky way... some 10 millions years ago. Who knows? The Universe makes you feel small, doesn't it... Link to comment
Pirilao Posted January 10, 2006 Author Share Posted January 10, 2006 I believe in intelligent extraterrestrial life. Do not exist evidences that support the idea of beings of other planets to visit the Globe nor of that exist intelligent life in the solar system are of the Globe. The great distances between the stars and the limitation of the speeds that the bodies can acquire become improbable such visits extremely. In the last decades, however, they have been stopped quarrels, constantly brought up to date, on the probability of extraterrestrial life. For the whole world, millions of annual dollars are expenses in research that searchs the detention of signals emitted for extraterrestrial intelligent civilizations. The great characteristic technological advance of our time can be in leading the wide steps for the detention of these signals that, a time caught, confirming the existence of intelligent extraterrestrial life, can come to modify significantly the current society human being.

Emakera Posted January 11, 2006 Share Posted January 11, 2006 I kinda like this kind of topic, ?cuz no one gets an exact answer, but we all get wiser from it. Well, we?re not alone in the universe. Probably there are at least bacterias somewhere. If there?s intelligent life forms out there, we?ll only know when we pay them a visit, or vice-versa, and i bet this is going to take an awfully long time... Link to comment
Koku Posted January 12, 2006 Share Posted January 12, 2006 * lid a 'glow in the dark' * I think we are not alone... However, we might be too far to reach our neighbour; either by distant travel, or by technology to make it possible...in near future... However, it's a good and constructive challenge to stretch our effort toward such goal, as the applications of the technology along the way is very fruitful. Link to comment
Gomaria Posted January 12, 2006 Share Posted January 12, 2006 myself I would like to find out what the hoot might try to probe me...... Link to comment
Orioni Posted January 14, 2006 Share Posted January 14, 2006 I must say I do agree with Europa. Sure there is other life in the galaxy. If we can be here, so can others. I just don't believe that extra terrestrials have visited earth. They exist, but they're probably not close-by. Link to comment
Tamurin Posted January 16, 2006 Share Posted January 16, 2006 Any kind of life needs precise conditions to function, and for this life form to actually become significant the margin in which it could exist would be tiny. This is correct - for Earth-based lifeforms. We have no frame of reference how non-Earth-based lifeforms could be. Mankind has just analyzed the life of one planet in a universe with so many stars that we can't even count them. How can we possibly say that there can be no other life out there? In my ears that sounds like the statement of a caveman saying that beyond the "big mountain" the end of the world awaits. Link to comment
Ide Jima Posted January 16, 2006 Share Posted January 16, 2006 The existence of any life form larger than single celled organisms in irregular or elliptical galaxies would be unrealistic. Planets are frequently subject to turbulence from supernovae in such galaxies, whilst we may not have a reference these events would cause such change that something would have to adapt to conditions left behind by this at a fantastically speedy rate. Whilst this isn't impossible, it is very unlikely, but for smaller life forms it would be easier. The force of gravity is universal, beyond a certain size, a planet won't even be able to support rocks more than a few feet high, let alone life forms. Anything too big would be crushed, regardless of how advanced it is. Such sizes would not allow for anything larger than ants, which are unlikely ever be regarded as intelligent (unless you take several billion years of evolution into account). Whilst these two things don't rule life out, they do make it very difficult. Certainly, life can adapt through evolution - but if a planet has been intolerable since it's existence it would be very difficult for life to start in the first place. Link to comment
Tamurin Posted January 17, 2006 Share Posted January 17, 2006 The existence of any life form larger than single celled organisms in irregular or elliptical galaxies would be unrealistic. Your facts look nice and I'm sure that they represent today's scientific opinion. But before Voyager 2, "today's scientific opinion" also stated, that vulcanism was something you wouldn't find on a moon...that "fact" died when the pictures of Io were sent back... So...unless an Earth survey ship scouts those galaxies and finds no life form, I won't accept such "impossible"-statements. They sound too much like "it is impossible to cross the Atlantic / to break the sound barrier / to build a computer that fits on a desk"... No offense to you, but as someone who studies history in his free time, I have often read some statements from scientists who "proved" that this or that was impossible... Link to comment
Nevareion Posted January 17, 2006 Share Posted January 17, 2006 I would say the chance of us being the only intelligent life, let alone the only life is so unlikely. We have lost all the other elements of Earth-centred thinking except this one. Link to comment
Ide Jima Posted January 17, 2006 Share Posted January 17, 2006 At the end of the day, what this argument comes down to is opinions. We won't be sure of this for a long time to come, but for the time being, I remain sceptical. Link to comment

Tamurin Posted January 18, 2006 Share Posted January 18, 2006 I have no problem with scepticism, Ide. I just have a problem with "impossible"-statements. Also, we SciFi-geeks need to have our sceptical counterparts... If we were to have more advanced weapons technology (all other technology doesn't count), history would be added with another colonization era... Link to comment
Ide Jima Posted January 18, 2006 Share Posted January 18, 2006 I suppose I did make a few very sweeping statements, still - two sides to every argument Link to comment
