Will it really happen to see life on the other planets? Does anyone believe the miracles of NANO Technology i?

If there is life on other planets (outside of our solar system), the odds of ever finding out that there is life there is infinitely, ridiculously small. The next-closest star to our solar system, Alpha Centauri, is just a shade under 4.3 light years away. Even if someone or something from a planet orbiting Alpha Centauri had the ability to travel the distance between our two solar systems and not die of starvation or, if they were able to achieve near-light speed, keep their molecular structures from becoming severely distorted, they would have to make an amazing pinpoint shot to hit Earth. Even if there is "intelligent" life out there, I think it's impossible for us to ever make any sort of meaningful contact with it. Anyone who has ever shot a rifle knows how just a fraction of a degree can determine a hit or miss on a distant target. The odds are that much more exponentially outlandish if we imagine interstellar travelers getting lucky enough to find our planet and solar system out of all the others out there, no matter how "close" we are.

I think since the universe is so big and since so much time has passed by, at least somewhere along the way, there was another form of intelligent life out there based on pure probability.  I don't remember the odds.\n\nHowever, I doubt we'll ever make contact with any other intelliegent life forms.  There are tons of theories out there why.  For one, humans have only existed for the briefiest of moments out of the life of the universe so the chance that another life form exists at the same time as us is really small.\n\nAlso, one of us would have to master interstellar travel in order to communicate effectively.  The universe is so big that there's a very low chance for collision.  Finally, our civilization is very weak, so our wimpy radio waves going out are such a small blip that a large civilization wouldn't be able to recognize it from just noise.\n\nThere's plenty of reading on the net about it.

Well extraterrestial planet hunting is only just beginning to be able to discover "smaller" planets. As before only the giant ones indicated their presence, by the effect of their gravity on the parent star.\nRemember even the most powerful telescopes on earth merely see a distant star as a point of light.\nAs for a signal, surveillance equipment is steadily becoming more sophisticated, and discoveries are continously being made to enhance the resolving power of the apparatus. \nMy view is life will not be that common, but a fair few systems will have, or have had life on them at some point. I am sure that in the next twenty years, an umistakeable signal, either intentional or not will be received on earth, and we will know that we are not alone.

Not yet, but that is the hope for the future. We hope to be able to create nano robots than can go in and repair our cells at the molecular level

No. Icy moons in the outer solar system may very well be teeming with life. Beyond our system there is definitely other intelligent life. \n\nHopefully a lot more intelligent.\n\nBeam me up, Scotty.

The one video shows what looks like something much larger than insects.Until people have had some sort of contact or psychic impression such as Remote Viewing it's too soon to tell.Maybe they are as one person said some type of probe. It could be possible for other civilizations to create organic devices or to mimic them. These might also be some sign of a return of a certain species or about some climactic event that's about to happen here.Yea I think I'll go with probes. Maybe nano probes?

Yes (personal judgment)\n\nwith the size of the universe as it is, it would be ignorant and elf-centered to say no. Especially since the sun is a mediocre star and the earth is a mediocre planet even in our system... Now, practically...\n\n-- Astronomers found planets by other stars, but not the size of Earth (too small for what we can detect now)\n-- the next star over is about 5 light years away? (not sure) so even if we travel at 99.999...% of light speed (as we are not massless) it would take ten years and trillions of trillions of dollars/Euro/tugrics, whatever you like. That is even if that star can support life.\n-- no reason to assume that there is multicellular life anywhere close, and if there is no reason to assume they are more advanced.\n-- Popular Science actually had an article last month on a non-DNA based "unicellular" primitive life that could have entered Earth on a small meteor. This is an idea scientists have been toying around with for a while. From my highchair it is possible, but I really don't know enough to say how probabble, afterall the space is mighty cold and the entery of our atmosphere mighty hot. Some say new viruses (which are not alive as virus is not a living entety) enter Earth in that way... that is doubtful since the DNA can't stand more than 50 degrees and the virus shell denatures at 42 (all in Celsius)\n\nI think there is life elsewhere but we will never see it... \n\nIf you have any more info or comments or just want to chat on this subject email me, I like interesting conversations.

In a few years we will be able to take readings of the atmospheres of exoplanets. That´s about it. But we could still be able to detect life on such a planet by studying it´s atmosphere. Molecular oxygen can´t be explained in another way.

Come to think of it... we all know that our planet is an insignificant speck circling an ordinary star, far out on a spiral arm of the Milky Way Galaxy, which is an ordinary congress of a few HUNDRED BILLION stars among at least a HUNDRED BILLION GALAXIES!!!\nWe are still the only intilligent life we know of anywhere. But now humankind has taken a dramatic leap towards a possible demotion. Planet-hunting scientists and astronomers world wide are refining their technique in detecting other planets in far off stars & galaxies. who knows that one day, we may be able to find a world that is much like ours?\nFor now, humanity can bask in its special status as the only life known to be contemplating such questions. Many scientists predicts that this distinction, too, will crumble. But the search for other worlds is not only a quest for kindred intelligenc. it is also about the destiny of human species. Where are we going to be a hundred million years from now? Where will we go, and how will we get there? And how will it change who we are? _end

Since there is no planet UMO in our solar system, I assume you are referring to a planet outside of our solar system.  \n\nScientists have discovered extrasolar planets,[1] but all of the planets we discovered are so far away, that even if we had sent a electronic signal to them the day we discovered one, since such signals move at the speed of light, our signal to them would not yet have arrived.[2]  Therefore, regardless of the name of the planets we have discovered, the limits imposed by the finite speed of light preclude the possibility of any ongoing communication with the planets (or more precisely, with any possible intelligent life that might inhabit them).\n\nIn short, no, there isn't.

Yes, I think it is possible.  We live in such a great universe and there is probably another life form out there.

Very little chance, considering most life will not exist outside our solar system from the huge heat of the planets.\n\nOHANDPOSTINGINCAPSLOCKSWITHNOSPACESMAKESYOUREALLYMATUREIMSUREYOUHAVEAHOTGFANDARETOSEXYFOREVERYONEHERE!!!

I assume you mean life on another planet since you can see the microscopic life here on Earth with a microscope, which is pretty good proof.\n\nThere is some disputed evidence of fossilized microbes in a meteorite that originated on Mars. Nothing more than that though.

Absolutely! The odds that they exist are overwhelming when you think of how GALAXIES are scattered like specks of dust!\nNow... even though aliens exist, what are the odds that they are on another planet in our galaxy right NOW? Think about it... It took 50 million years for humans to appear on Earth. How long will we be here?... only 50 to 100 thousand years (hopefully)? How many other planets will bring forth intelligent life - not a whole heck of a lot. And of them, when will that life be around? Just a tiny amount of relative time.\n...What I am saying is that EVEN IF other civilizations were, are, or will be... the timeline of the universe is too insanely long for any of us to be co-existing. The reality may very well be that we are currently very alone here in our time and place. I hope this gives you a new, more realistic way of seeing things. Sorry it's such a downer, though!

Yes!  I think it could most definitely happen to us.  One would have to be very naive and simple-minded to think it could not happen.  Many people don't let current FACTS actually sink into their brain.  There are so many conditions on other planets that are habitable for small organisms.  Certain bacteria(extremophiles) thrive on extreme living conditions.  That is how life started on our planet, and if nothing else there are definitely other forms of life elsewhere.  But still, someone would have to be so self involved to think that there couldn't possibly be a other life form of superior intelligence.

Very niave!  We have been shown that there are other living organisms on other planets that we have have snet out to study.  Just because they are not in human or (our) peoples form does not mean that the planet is not alive. We have also been shown to where some planets have shown previous life on them.

The short answer is: \n- - - - - - - - - - - \n\nYes I think it is fairly likely that there is life someplace outside our solar system. I have written a short historical survey, and then summarized some of the reasons behind my answer. They boil down to 2 points:\n\n1. The universe is a big place\n2. Life seems to be pretty common here on earth and start pretty easily. \n\nThe Long answer:\n- - - - - - - - - - - \n\nA. History\n- - - - - - - \n\nThis is a question that people have asked for a long time. The Greek philospher Epicurius (341–270 B.C) speculated that there were an infinite number of other planets like earth, with life on them, in the universe:\n\n“There are infinite worlds both like and unlike this world of ours...We must believe that in all worlds there are living creatures and planets and other things we see in this world.” Epicurius (c. 300 B.C)\n\nThe Dominican Monk and philospher Giodarno Bruno conjected in his 1584 work, "On the Infinite Universe and Worlds", that there were an infinite number of other worlds with intelligent life on them. He refused to recant this and other controversial beliefs, and was burned at the stake during the Inquisition for this. \n\nThe famous physicist Enrico Fermi formulated the Fermi Paradox (sometimes known as the Fermi Principle by skeptics), which states that if advanced intelligent life was widespread in the universe, we would have evidence of it already. Since we do not have good evidence, where are they? \n\nThis was later addressed by Frank Drake with his Drake equation (aka the Sagan equation or the Green Bank equation) for trying to estimate the probability of using coming in contact with an advanced extraterrestrial civilization. \n\nBoth a modification of the Drake Equation and the analyses associated with the Fermi Paradox can be used to try to estimate the likelihood of there being life beyond our solar system (the interested reader is directed to the references). Basically, depending on what is assumed for a number of parameters, it appears either quite likely that there is life outside the solar system, or quite unlikely. However, at least one has a better handle on what the quantitative factors are that go into estimating this probability by this kind of investigation. \n\n\nB. Reasoning Behind my Opinion\n- - - - - - - - - - - - - - - - - - - - -\n\n\nMy own opinion, after having read this material and some of the links contained, is that it is quite possible that life exists beyond our solar system, or even possibly does or has in other places in our solar system than earth. \n\nFirst, consider the very large number of stars even in our own galaxy (200-400 billion) and the large number of visible galaxies. This leads to about 7x10^22 stars in the visible universe (according to  Dr Simon Driver of ANU). This is more than 10 times the number of grains of sand on earth. This is 100 billion times more than the number of letters in the 14 million books in the Library of Congress. If this is coupled with the seeming presence of a large number of exoplanets around these stars (170 found as of the end of 2005, and we have barely started looking), then this translates into a HUGE number of planets. With this extremely large number of potential planets, there are bound to be some like earth. \n\nLife seems to thrive readily, since life started soon after the earth cooled and existing in environments that we can barely imagine, like miles underground, or near deep ocean vents, or under the Antarctic ice. It has been well known for years that there are amino acids, the building blocks of life on meteors in space. Scientists have also created amino acids in environments similar to deep space environments (see reference). The Miller-Urey experiments in the 1950s were also able to readily create amino acids in environments meant to duplicate a primordial earth environment (reference below). \n\nWith the evidence that there are probably many planets with eart
