Jill Tarter: Why the search for alien intelligence matters

[@Ramshobraja]

You can tell how passionate she is about this. Truly an amazing individual. SETI is an amazing quest, too bad it has recently been shut down.

[@SuperYtc1]

It's open.

[@ketchupcommander]

her lies need shut down

[@Iamstupid51]

If the universe is so big and the speed of light is so relatively slow, it should be no surprise that we haven't found aliens yet.

[@EricKlien]

Any civilization in our galaxy would have had plenty of time to colonize every solar system in this galaxy.

[@SuperYtc1]

@@EricKlien I don't agree with this. We don't know how difficult it may be to colonize the galaxy. Even with all of our technology we haven't even been able to land a human on the planet nearest to us. And technology doesn't improve indefinitely. There will be limits.

[@grahamwohlers7130]

@@SuperYtc1 Those are a lot of assumptions you just made to detest eric's theory. How do you know technological advancement has limits? There is no evidence of that. Why is not having landed on a planet yet proof that it is improbable that alien life could do it?

Carl Sagan was Jill Tartar's colleague and collaborator in the search for extraterrestrial life. Many sources also credit her with being the model for Contact's heroine Ellie Arroway. Quite possibly some of Sagan's signature cosmic prose was in fact Tartar's.

[@TheFallibleFiend]

They didn't mention it in the side bar: SHE was actually the inspiration for Carl's book "Contact."

Sure, there are lots of problems down here on Earth. There will always be problems. But we still need to put some effort on something higher than that, something that has more meaning to mankind as a whole than to individual people. We are all in the gutter, but some of us are looking at the stars. - Oscar Wilde

[@liamnute5032]

Id love to see the architecture of civilizations advanced enough to communicate on such a puzzling intergalactic or universal and possibly an inter-dimensional level, two words; ferocious astonishment. Their crafts alone display superior knowledge, style, capability and sheer BADASSNESS. In mans ever growing Goliath of space travel, we are throwing pretty well refined stones.

[@kakudmi]

I am not joining the club. I am getting a farm and growing my own food and this club you're talking about can be on its way to wherever it is going. I don't have to be a part of this and I currently have the whole community of like-minded people who actually see what is being done in the world today and we all say: you can keep it! Yes I did find it and the knowledge is called the Vedas. If you're interested you can study it. I've been studying it for the past 15 years and I am so happy with it.

[@ancalites]

Excellent quality. One thing to point out about her comment regarding Andromeda being the closet galaxy, though; What she means is that Andromeda is the closet large spiral galaxy of kind similar to our own. The actual closet galaxy that can be called as such is a small "dwarf" galaxy known as the Canis Major Dwarf - just 25 000 light years from Sol.

[@havocman100]

hence why i said time is "relative", the clock on a spaceship moving at light speed would be ticking normally", but from an observer on the outside that same clock would be not moving. and with regards to superstring and multi-dimensions, but no technology allows for a particle to move faster than light (that we know of), i did not mention tricking space-time with something like a wormhole, allowing u to beat light to a particular destination whilst moving slower than light

[@Promatheos]

I agree. It's important that all of us, children of this wonderful cosmos, look for each other. As it has been said, "Either we're alone or we're not alone, but both are equally thrilling to think about."

[@taratarotweb]

this woman is brilliant. We are not the top dog, we are not the culmination of Life's chain on earth. we are but one small branch of organisms here.

On the contrary, I think Dr Jill Tarter is an excellent speaker. Obviously very educated and passionate in what she does and believes in. I like her a great deal.

[@MewFushisDad]

Brilliant! Ms Tarter is an exceptional speaker.

[@Megneous]

For those of you who didn't realize, this is a very old recording. Kepler has confirmed, as of the writing of this comment, 861 extrasolar planets, with thousands more candidates waiting to be confirmed. The future will soon be not about finding extrasolar planets... but how to design feasible methods of getting there.

[@TechNed]

You missed a step - deciding which candidates to search first.

[@Kevin-xs8xn]

some notes... “we live on a fragile island of life” “if we’re alone…incredible waste of space” discovering other cultured civilizations could enhance humanity’s bonds with each other “we’re a billion year lineage of wandering stardust” SETI began 50 years ago sun is one of 400 billion stars in Milky Way, among 100 billion other galaxies (!) the more we learn the wider our “livable space” becomes (eg, the more habitable stars we’ve discovered, the more species we’ve discovered here on Earth that live in extreme environments) SETI is the archaeology of the future (when we look into the night sky, we’re looking into our past) on Earth, life happened quickly, Earth spent majority of its time (90+%) developing life, not waiting for it to arise Copernican revolution changed our thinking in many areas (astronomy, physics, theology), discovery of ETI would be comparable Drake conducted first SETI observation of distant stars “we all belong to one tribe, Earthlings” kevinhabits.com/ted-talk-notes-2-jill-tarter-why-the-search-for-alien-intelligence-matters/

[@xdoriandanger]

This blows my mind. It is bittersweet, the idea that a signal we could receive would be "old" by the time it reaches us. Could you imagine hearing a signal of peace and a promise of beauty from another human-inhabited planet, only to have us travel there somehow and find it in ruins? How interesting, yet bittersweet...

[@shack6000]

This is the best TED talk ever!!!

[@orlando098]

One thing that occurs to me with all this - there are probably 10s of millions of species on Earth and we are the only one that could really be said to be "intelligent", so that makes the search for such life even harder, considering we have not yet even got evidence for any ET life of any kind yet.

[@kittimcconnell2633]

Good point; SETI is a better focus for thought than petty differences such as race or religion.

[@adamatepsilon9858]

the distance to the Andromeda Galaxy is hard to fathom as it is so far away. But I did a rough calculation out of interest a few months ago and came to the result that the distance to the Andromeda galaxy equals 20 Milky-Way galaxy diameters.

[@araptuga]

True dat. But with a little patience (say, a couple billion years), it'll only be half that!

[@kindofpoetry]

I see what you're saying, but if the only thing that results from SETI is a change in human perspective, it will still be a monumental achievement. right now, we see ourselves as distinct societies, separated from each other by culture and geography. with the discovery of other civilizations on entirely different planets, we could find a sense of unity that has been lacking since the human race began. it sounds unlikely, but I really think that it's what the earth needs.

[@amirdoit]

[@chilledhoney]

SETI SIGNAL 6EQUJ5 "WOW" Code meaning maybe: The "EQUJ" is Equine meaning "horse" hence the constellation Sagittarius. the "6" is a beginning greeting, and the "5" is an ending salutation. The signal is Strongest at the "U" The "J" is also sometimes used as vowel instead of "I". The 6EQUJ5 code meaning is as follows: "Hello (6), from the "horse" (EQUJ or EQUI)constellation Sagittaruis, (5) Goodbye". This message may have taken 10,000 years to reach earth. Signal is from Sagittaruis, research it

[@sirachman]

While we have many other problems, this other than moving ourselves physically into permanent residence off planet and preserving Earth is the most important thing we can do. Discovery of other intelligent life would be a massive wakeup call that would help every other science pursuit in a way unmatchable by any other method.

[@Desert2GardenLV]

This lady is not a typical ted talk. She has a quite low vibration. I didnt feel inspired. She does have a few good ideas if you call them that. Regretful that she won an award. Cant wait for the next talk.

[@11kirky]

at the same place are you saying that they will both be 1sec=1sec. The other thing is the cern facility, they have done tests on neutrinos thousands of times and when the traces came back they were appearing earlier than anticipated, now i know they've said they found a glitch with a recording instruments but to foul up like that i find...unusual. As for multi dimensions the same establishment along with i think the large hadron collider found that when atoms were being traced at light speed.

[@momentary_]

As others have said, the scale of distance and time involved is an enormous hurdle. I would love it if we found a signal, but I don't think it is all that important to moving forward as a species or as a civilization.

[@illisssy]

[@naryanr]

Yeah it is. He's saying that introducing something we totally can't handle will somehow magically make us realise how bad the thing we've been experiencing has been all along.

[@JimJWalker]

I am not so optimistic that a revelation such as the existence of extraterrestrial intelligence would hold the human imagination for as long as one may think. It would simply become an empty footnote to be acknowledged, as sadly the distances and time differentials prevent any interaction after the fact of discovery.

[@carlacavallimariotti8325]

Got your point, but it would be a blink to the "open mind"

[@araptuga]

Of course that depends on just how far away they are. Chances of anyone to talk to being within say 30 light years (so that we could send a message and get a reply within your lifetime) are admittedly small. But even if we detected someone 1000 light years away, just knowing someone is out there will, I think, have profound effects over time. Knowing there's another race out there (and if one, likely many) -- and statistically, one far advanced than our own -- is bound to get people thinking and discussing what that means for us. Are they dangerous? Can they provide us with clues on how to survive or even thrive? Or at least, give us context for those persistent questions about our origins, and the meaning of life.

[@the_mastermage]

[@bobopatchy]

People have always been searching for more room(i forgot the theory or whatever its called) but people have always found another continent or place to live. So, first I think humans will be able to live in the ocean, then sky, then space. Its just an opinion, so id appreciate it if no one starts arguing about it :)

[@kakudmi]

Naturally, if you imagine only two realities: The one we have now, and the one we have in the dark ages, then yes, one would resist to change. But I've never suggested dark ages, you did. If the child turns out to be a bad person, it's his parents to blame. They had a chance to raise him properly but they didn't, regardless of the excuses. So scientists today, while developing a-bomb or a similar destruction, are like those parents, fully able to make rational decisions, not just work for money.

[@freenational]

Outstanding speech but the speaker did not address about the probability of extraterrestrial civilizations being hostile ones or that Earthlings may be considered too hostile for extraterrestrial civilizations to want to contact us.

[@Trazynn]

I really like the episode 'Rare Earth' by the BBC and presented by Iain Stewart. It's on youtube somewhere. Really worth checking (stunning visuals as well).

Graduate and live a good life, my friend. All the best to you. My whole point is that Reality, here and now, trumps wishful thinking.

[@magicalgold010]

" the story of humans is a story of idead, that shine light into dark corners "

[@DeadWhiteButterflies]

If the stars all consist of old light, how can we possibly ever observe universe in it's current state? How can we know all the stars are still there if they're dead and we're just seeing the afterglow of a universe long gone? Just sharing my thoughts.

[@araptuga]

Yes, the light is "old" by the time it reaches us, but only by somewhere in the range of a few years to a few thousand years. That's nothing compared to the lifetime of stars. More than 95% of stars live billions to trillions of years -- meaning almost all of them are still in existence today, since the universe itself is less than 14 billion years old. (even the rare stars with shorter lifetimes live millions of years -- but those aren't likely to have intelligent life anyway, so we won't be in contact with anyone there). So basically, if we hear from anyone, the chances are 99.99999999999% that they will still be there, now and for a VERY long time into the future.

[@pcpolarbear1]

every thing we know points to the fact that there must be life elsewhere in this gigantic universe, it is mathmatically impossibly for there to not be.

[@WhiteRussianBC]

She is the only person that can even make me consider the existence of extraterrestrial life. But when she's done talking logic comes back to me and I forget all about it. However, great speech!

[@Flyborg]

With our current level of technology, looking for intelligent life in the universe is sort of like looking for humans on Earth, by going out into the middle of a desert, reaching your arms out, and seeing if you feel anyone within 2 feet of you. The amount of our galaxy that we can even partially see from the Earth is a tiny fraction of a fraction of 0.1%, and this is just one galaxy of at least 80 billion.

[@theragemachineau3855]

Try 100 billion galaxies. First we need to work on uniting ourselves, before we go out and start exploring for others. Because we don’t even truly know who we are as a species yet. We fight over the trivial and horde materialistic values. First unite the planet, solve our own issues first. Then reach out into the cosmos.

i think you misunderstood my comment, when i say "tricking space time", i mean to cheat and use a wormhole, or use some type of warp drive to compress and expand space time, without going faster than light. and with regards to the neutrinos, it was reported that they had some loose cables, is that possible, certainly. but more data is needed. all i am saying is that, sure theoretically is it possible to pull some tricky quantum physics and move particles around in terms of dimensions and...

If you want to boil it down that much i'd say "take everything with a grain of salt, find out for yourself and don't take someone else's word for it" would be a better analogue.

[@havocman100]

.. spacetime to a position faster than light could arrive, of course. my point is that to scale it up and somehow apply that to a spacecraft, we simply dont have any way of doing it (yet). wormholes appear to be unstable, warp drives require too much energy and are also too unstable due to their antimatter bubble, and multi-dimensions are still purely theoretical. thats all i was saying

[@cmcil]

nicely put!

[@Promatheos]

We won't find intelligent life elsewhere. Considering the size of the distance and timescales involved, the chances may as well be equal to zero. And even if, against all odds, we found signals of intelligence, we wouldn't be able to communicate with them anyway. Not only because of a language barrier, but because by the time our message got back it would be thousands of years later at least.

[@davidshaw7454]

Excellent talk !!!!

[@Za7a7aZ]

The thing I do not understand is that Seth Shostak (senior scientist at SETI) does not belief that Earth is being visited by ET. His argument is that the distance for a visit is too far. Such thoughts are too narrow minded for a scientist working at an organisation like SETI.

[@kakudmi]

I've mentioned scientists because they were supposed to be the brains of our society, and if the society is rotten, it means that the brain is rotten.You cannot blame your mother for buying a plastic cup, but the ones that decided that plastic cups should be made and sold publicly. It is a sign of irresponsible actions and if scientists are not responsible for their actions,they should stop doing their work and do something else.Responsibility is hard to get these days,everyone is washing hands.

[@havocman100]

no worries man. trying to get a point across on the internet is not the easiest thing in the world to do

I was trying to paint a bigger picture about the nature of humanity and how it has been herded throughout history. Peer pressure, argument by authority and taking things at face value. Stephen Hawking actually said something along those lines though. "If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn't turn out very well for the American Indians."

If you're saying that all the planets with life are the same age and formed at the same time I don't think that's the case. See some stars are billions of yrs. older than ours so if there was a planet in the right spot life would have evolved a lot sooner than here, giving that species if intelligent much more time to evolve. That and new stars and planets are formed all the time. Actually about 4000 stars every sec. are formed. So there's likely life developing on another planet at this moment.

[@Evenstar100]

It would seem that a number of the previous comments are founded in our present scientific and technological understanding and capability. Would Early Man have thought that technology would progress to time when the humans would travel into space? Technologies have been and are being developed that allow us to see deeper into the universe than ever before. Human beings arrived here through experimentation, risk taking and determination it is this that moves us forward. SETI is doing just that.

[@LynxChan]

The goal of finding life on other planets is a great one and it's impact cannot be understated, I disagree about it changing things so much as to make us a global community. The same thing was said when we got the first images of Earth from space; humans would realize we're all in the same boat together, that our differences are insignificant. Obviously that prediction did not come true. It would be a great discovery, but it would not cure people like Punniabi here, I'm afraid.

[@randy95023]

Agree or Disagree, this is an interesting lecture. Not to be pessimistic but if she thinks we will overcome our "Tribalism" and become "one with each other as Earthlings" I'm afraid we are going the wrong direction.

Hmm... What does it mean? Manmade Signal? Prank? or...

[@11kirky]

I never accused you of tricking space time, just thinking outside the box mate, anyway,when you say 1 second is 1 second, is that strictly true, when the astronauts went to the moon and came back their clock recorded thousands of a second less than earth time which makes it slightly less than 1 sec = 1sec because of time dilation. Now if you had 2 spacecraft at the speed of light flying at 1sec=1sec alongside each other and 1 craft hits a magnetic wave and time slows but they end up arriving.
