  • Incredible guy. Really knows his stuff.

  • infowars . com

    PLEASE LOOK THIS UP, OUR EARTH IS DIEING!

  • he seamed very nervous at first, but he gave a great and informative presentation, and also seams like a nice person :)

  • Only thing I would like to be skeptical about is giving years in when science discovers something... if there's something I've learnt is that these predictions are usually wrong.

  • thumb up you bastards ! this guy is genious

  • I wish women would procreat with this guy. We need more scientifically-smart people like this on Earth

  • good talk but he sounded liek he was going to die lol

    nervous much

  • Very interesting talk. I loved how he had an Asgard from Stargate as his alien picture :D

  • I just watched a video that said the actual size of the universe (visible) if you take space time into account, it would make the universe 92 billion light years large, The areas in a galaxy in which a earth type planet could even possibly form is limited to about 5 percent of a individual galaxy because of deadly gamma rays, etc. Watch the how large is our universe video, it's in my favorite if you click the top right button.

  • If the universe is 14 billion years old, and it took 9 billion years to get an element like carbon, (the only element that can support COMPLEX molecular formations) this then leaves roughly 5 billion years, which is the approximate age of the earth. Does this then mean that the earth is as old as any planet in the universe that can have advanced intelligent life?

  • Not all stars and planets are created at the same time; stars have their own life cycle including deaths, and not all galaxies were created at the same time; so another planet which could have life could be older or younger than the earth; remember space is constantly expanding since the big bang and different galaxies were formed at different times, and are still being created now i'm sure.

  • I agree, there are galaxies much older than our own. And planets, due to their method of creation, must be younger than the stars they encircle. But as you said, the universe is expanding, and it's expansion is "flat" or even. What's here is what's there, is what's over there. And so the question becomes one of the chance of the abundance of carbon in said galaxy, not about the question of whether said galaxy is older than another.  The older galaxies would have had less, or no, carbon.

  • I proud of my father :)

    pap jan i love u ;-)

  • he has a good delivery, nothing phoney about him

  • bulgaria?

    what's his nationality?

  • he's pure Armenian. Living in Tenerife, working in IAC

  • I thought he was greek or something, but that makes sense. What was the name of the bulgarian scientist , can u hear it correctly?

    I didnt get his pronunciation.

  • Heres a story:

    On a planet far away, two aliens are sitting on a couch watching a tv show about life on other planets. One asks "I wonder if there is life on Earth?" the other says "Don't be silly! There is too much water and oxygen and not enough radium."

    If you want to believe in alien life you need to first believe in evolution. Then don't forget Anaerobic organisms. Scientists will want to ignore this because this little factor actually means life could be almost ANYWHERE.

  • And scientists don't want there to be life everywhere?

    The notion that water is necessary for life isn't anthropocentric, it's very fundamental physics. Water allows organic compounds to replicate.

    The only partially reasonable alternatives are ammonia and hydrogen fluoride, yet the former has much weaker hydrogen bonds than water and the latter is improbable to be found in large quantities, especially since silicates would react with it to form inert compounds.

  • @Saerain "The notion that water is necessary for life isn't anthropocentric, it's very fundamental physics."

    No.

    Water is necessary for life _as we know it_.

    What is good or optimal for other forms of life, we cannot begin to know.

    The more we know, the more we know that we don't know.

    However, when looking for life, it's best to start with the types of life for which we have evidence of existence (i.e. the type we find here on earth).

    If we don't, we'll blunder about blindly without a clue.

  • Besides, the argument about how common water is throughout the universe is very well moot at this point. We're finding it everywhere. On our own moon, on Mars, in Saturn's rings, on Saturn's moons, on Jupiter's moons, and in spectroscopic imagery of exoplanets. We're bound to find plenty of life in the galaxy, at least in very simple forms.

  • @superchimp

    The thing about anaerobic life: Yes, it's possible to have life without free oxygen. The reason SETI people are so interested in O2 is that free oxygen is unlikely to exist in large quantities without life.

  • good lecture, but he said -200 kelvin, rofl

  • I'm sure the guy fully understands kelvin. Maybe he was nervous or something.

  • I am sure he does. He probably meant to say -200 celsius but got lost in translation.

  • I wonder where this guy is from? LOL

  • With all due respect: you don't seem to have any idea of the (often irreducible) complexity of life. This has nothing to do with arrogance. Earth has been extremely fine tuned to support life. God is not an "old bearded guy", but the unmoved mover outside of space-time. Ever heard of thermodynamics/entropy? The universe is not improving, it's running down, implying a start-up. Matter + energy + time do not lead to organization, you need intelligence for that. Not to mention origin of morals etc.

  • Well looks like ure close minded person and ure wrong from start, organization of atom is not based on its intelligence but on matter+energy+time, 1+1=2 and the fact that someone is dumb dont change that for the rest of the world but only for him.

    Earth is not tuned to support life, life is byproduct/result of different elements.

    For it to be the way ure saying there would be HUMAN first and the the EARTH would form but thats not the case. There was earth and then we came/developed.

  • The fact is that the conditions found on earth are extremely uncommon (O2 based atmosphere, active iron core, the right position from it's star and so on) We have yet to find a planet that meets all these prerequisites and even then it's not certain that we'll find life. Life is not a natural occurence in the universe it's more like a glitch in the system,

  • There is billions of planets so u cant say that is uncommon, when we explore all the planets then u can say that it is uncommon. Also why cant u accept the fact that conditions u have mentioned are needed for this kind of life form. Same as there are species on earth that need extreme temperatures to live but human would die under those conditions. Universe is full of life and to think that we are only ones is more than STUPID!

  • i wouldnt jump to the assumption that the universe is full of life, but even then, i am not also to agree wif the fact tht we are the only ones, its just tht we simply cant come to any conclusion yet, since as u have said, we have yet to adequately explore even a percent of the universe

  • I don't appreciate being insulted just because I don't agree with you. Plus I never said we're the only ones just that if there is extraterrestrial life it wouldn't be so abundant like the movies portray it. Also we only know our carbon-based life form so we can draw conclusions only on it. Yes there are bacteria that live in boiling water and so on, but the all living beings on earth share 90% of their genetic structure.

  • There are the same laws of physics throughout the universe, so there's a good chancel that life would take exactly the same form as life on earth and so require the exact same conditions. To believe there are fantastic creatures made of gas or whatever is IDIOTIC!

  • You Sir (?) are a Idiot and have no idea how evolution works! It´s not a detirmeted process. Read a book about evolution and than come back and make your comments.

  • Maybe you should go back to school and learn to spell again... AN idiot and detirmeted? I don't even know what you were going for there. Pretty good try I guess.

  • Hi, I am from Germany, english is not my mothertounge, so i spell some words wrong, sry. But my point remains, even on earth there are a couple of different animals with different metabolisms, such as bactiria with sulfur based brathing, and even life that is based on ironoxidation.

    I hope you get my point, and let me ask you, how many languages do you speak?

  • Learn to spell first, reading a first grade schoolbook will help. And then go and throw insults. Evolution has nothing to do with our discussion here so I suggest you go and watch some laughing babies videos or something.

  • Here we go again, why are u referring to earth organisms? We are talking about organisms that would live under different conditions, so they MUST be different than ones on earth, so simple but yet so difficult for you to understand. Oh, and im not insulting you, you are doing it if you think that we are the only ones. This is not meant to insult you but to express my opinion on the subject.

  • nothing is idiotic... there are more things in heaven and earth, imalimase, than are dreamt of in your philosophy.

  • Without proof you're telling me nothing. Face it, the universe is a lonely place and with the rate it's expanding, even if there's life somewhere the chances are good we will NEVER find it.

  • If you qualify that by specifying that you mean intelligent life, then I agree with you wholeheartedly. The chances of intelligent life evolving are high, but the chances of intelligent life evolving on two planets in the same galaxy at the same time are very low, unless we assume that intelligent species often last more than 100k years after developing radio communication.

    Of course, maybe that is the case, and that's why we look and listen, but we have no reason currently to believe so.

  • In about 1977 when they were doing radio signal reception testing to space they did receive what they believed to be radio signals from a distant source, but after that they were not able to relocate it. With modern technology, we probably could find iti; but we would be unable to visit there.

  • if youre talking about the guy that wanted to find the source of white noise within radios etc in the 70s. they later found the source to be the supermassive black hole located in the center of our galaxy

  • Don't debate issues in which you have no understanding of. Thermodynamics does not support creation and your hilarious matter+energy+time equation shows your ignorance on the topic. I'm assuming your a Christian, or some for of it, and the biblical view of creation is absurd. Update your arguments instead of regurgitating the same bullshit.

  • form**

  • Ohhhhhh Pul-ease!

  • sigh, arguments from design

  • Actuall,y God is a flying spaghetti monster, and if you were better educated you would know that.

  • Alien star? kewl :D

  • First off i'd like to start with a Death to Israel! and continue on with my famous ***** Goyim of the World, Unite! *****

    while finishing off with forwarding you to videos introducing Plasma Cosmology for your consideration, a new and old "science" at once and much laughed at by the academic establishment. Yet it is highly likely the truth..

  • I dont understand why are ppl so focused on oxygen and water as a must for life on some planet, there might be other life forms made of gas or some other material that live in lava or fire or just lifeform that is pure energy etc...

    Water based lifeform that need air like us is on planet that is made of water and has oxygen, so we are adapted to our environment, other lifeforms are adapted to their...

  • No, we have not "adapted" to our environment, we simply wouldn't exist without these conditions. Life is not something normal in the universe, it's an anomaly that requires many factors to occur.

  • There is no "anomaly", everything is normal.

    Ppl like to think that they are special but we are not, there is plenty of life in universe.

    Water and air are what is needed to live on this planet, to live on planet with gas u would need to be life form that breaths gas or is made of gas or any other substance.

    We are not product of some old bearded guy, we are product of different atoms coming together. Just like they do anywhere in universe. And then we evolved. ( well some of us...)

  • Absolutely markok27.

    We really don't know what other lifeforms could exist, what environments they could survive in, and they could be based on other processes altogether.

    We now know of basic life surviving long periods in space, in the insides of nuclear power plants, and who would have guessed we'de find the myriad lifeforms we did around the ocean floor vents (Black Smokers).

    Although the universe is all made of the same stuff, to image life can only exist as on Earth is a little arrogant.

  • 04:28 Minus 200 Kelvin...? Isn't the absolute point zero at 0 Kelvin (K)? Isn't it how you would define Kelvin? At 0 K, the particles stop vibrating and thus stop emitting heat. How could you possibly get a particle to vibrate less than not at all??

  • he meant Celsius I guess :)

  • Great as always.

  • Excellent spectroscopy video, can't wait to see the results of Keppler combined with the new 'greater' HARPS they are constructing. Exiting times

  • AMAZING!!

  • Very interesting: He has an Iranian Accent but his name says "Israelian" .. is he a israeli scientist?

  • that's a 100% jewish armenian last name.

  • LMFAO

  • Cant see the comments

  • i <3 Rolex

  • Awesome! But, I don't understand why he says he isn't looking at the star? How is looking at spectrum chart any different than using a computer attached to a camera reinterpreting a ccd or cmos data pixel array into into a visual picture on an lcd pixel array any different? One is a data sheet that the brain interprets visually as a data abstraction containing visual data and the other is merely a reinterpretation of collected photons for immediate visual evaluation. Both require interpretation.

  • The way I hear it is that that method isn't sensitive enough. You're standard JPEG image only has a few thousand pixel color options, and if you take a picture fo the sun, imagine how many of them could be represented in that yellowish range. They need to seperate the light and judge the distance between the color bands in order to interpret the composition.

  • brilliant! :D

  • most interesting and sensible talk from TED in a while -

  • Plants .. sending out a call to the universe ...

    We are here .. We are here ...

    And now there is a species that is capable of hearing the call, and perhaps even answering it ...

  • He can't very well tell us he can find life, when we have yet to finish defineing it.

  • His views of the parameters for life are not based on fact yet expressed as such. They are merely assumptions.

  • "They are merely assumptions"

    ...That have been based on fact.

  • A mole wizard should know better.

  • I'm sorry, what??

  • good video!

  • rolex ad was impresive too.

  • heh heh...good call

  • Good and the bad. The bad made this really good!

  • This is real pioneering!

    I just love listening to this, this is the future of some science :-)

  • -200 Kelvin? Oops!

  • This is what TED should be about, not this other stuff that keeps popping up like the woman who banged on about the "Golden Rule"...

  • I agree, but, TED is Technology, Entertainment, Design. So, pretty much everything is able to be talked about at TED>

  • If a planet is void of tectonic activity does that mean it is too cold to support life as we know it?

  • Probably, but it's also a very basic mechanical issue - it'd be like trying to make bread and not stir the dough. You need to have a continuous recycling and redistribution of elements to have a working ecosystem, at least if you want something even remotely like what we have here.

    For example, hot ocean floor vents wouldn't exist without volcanic activity.

  • hahaahah is there anybody out there awesome!

  • This leaves me to wonder if NASA has ever thought to have one of their telescope satellites orbit a planet which is further out in the solar system.

  • There is a NASA spacecraft on its way to orbiting mercury, will be a couple years though.

  • I think they should try something further away from the sun though - not closer.

  • physics is AWESOME.

    fuck your religion.

  • amen to that (wink)

  • Comment removed

  • Haruhide86 ____ HE is not a Jew but even if he is one whats your point?

  • Very impressive.

  • Stop it ALL!!

    We are AL-ONE!!

    Even if there was "life" out there, that would not change the deceptive human nature - there would still be wars and starvation and conflict etc... We cant even sort this out (aparently) and we are already thinking about meeting someone or something (who/that will save us?like "god"?) ... and then what? We would remain the same shit.

    thus - we must take responsibility for ourselves and stop ALL mess - then we can have fun in this UNIverse.

    We are ALL-ONE!

  • You know... TED is mented to change THAT "deceptive human nature" in the first place... so, i'll invite you to stop being negative and start thinking -or dreaming- TED

  • i believe in extraterrestrial life, i believe they influence in history, pyramids, coral castle, UFOs and i believe they are closer than we could imagine.

  • That is the amazing thing about "beLIEf":one can beLIEve anything and justify it with "I have free will,I have the choice"-which is also but a belief.

    That is no diferent than believing in a god -god influenced history,the piramids etc..it inFLUences the now..entertains everyone,distracts..and we do not stand up and take responsibility for ourselves.

    If you have a look at your life,you will see how your beliefs entertain you and justify you not taking action to sort yourself and the world out.

  • and what wold motivate your life if you don't believe in anything. stand up to what?? for what purpose?? you are demoralizing life.

  • tenisplayer,

    How about believing in love as an ideal and striving for it?

    How about believing in justice as an ideal and striving for it?

    How about believing in joy and enjoyment and teaching self and others to live it?

    I believe in those.

    And I do not need to believe in deities or any other supernatural entities to hold to those purposes in life.

    I hope I have provided an example of how you can live without belief in the supernatural or "demoralizing life".

  • People believe in stuff because they do not KNOW - if you KNOW, you do not require a beLIEf - you simply know.

    To "stand up" for beLIEfs is to stand up for LIEs. One can only STAND UP for REALITY, everything else will be a "stand up" for ILLusions.

    Reality is EQUALITY and ONENESS - as that WHICH IS CANNOT be SEPERATE from it-SELF.

    This is what I stand up for, since this is WHO I AM / WHO YOU ARE / REALITY -- THIS is LIFE.

    Thus, LIFE is the MOTIVE, LIFE is the MOveMENT.

  • If you don't believe you don't act.

    believe in change.

    believe that it matters.

    believe you can make the difference.

    believe it could be.

    IF YOU DON'T WHATS THE POINT OF DOING.

    but to know something and understanding for sure its hard.

  • I have no choice but to act

    I have no choice but to stop and change all my dishonest behaviours

    I have no choice but MATTER -the physical!

    I have no choice but to "make the diference" and be the ONENESS

    I have no choice but to BE WHO I AM, because the POINT is ME / REALITY -not a beLIEf

    Have a look for yourself how beliefs control you and your life, making you be dishonest:"I dont belief I can do it"/"I dont belief I am good enough"/"I dont belief I deserve it"

    Beliefs are mind made Illusions.

  • Just cause someone doesn't believe in supernatural beings doesn't mean he believes in nothing and has nothing to live for. Only people in deep depression can believe in nothing. You're really close-minded.

  • try convincing everyone...

  • That was a really good talk. I'd like to know what the results are with those Stars with odd spectra!

  • Great work! Looking forward to seeing the hard work pay off.

  • Amazing work 1

  • Jesus, don't those cameras have tripods? That dude's arm looked like it was about to fall off.

  • I am amazed! To see that there's water and/or vegetation from a SPECTRUM! wow!

  • Sounds hopeful, we need something else to consentrate on, maby finding other life would bring humans together.

  • Thats awesome, I'm glad we have scientists with enough passion and patience to study phenomena like this.

  • can anyone tell me the name of the vid of the man who made the protein from pig heart cells to kill anthrax?

  • can any fellow ted fans recommend other awesome channels, the reason i ask is because i have only one other to recommend myself, Informed Citizen News

  • lwanatt - look at the playlists or subscription list at TheKnowledgeProject channel

  • they is foratv

  • faved... this video is why i love youtube...

  • this kinda makes me wanna go to school and get straight into astronomy

  • fuck looking at stars from earth, i wanna travel there

  • i want to eat other planets.

    you, give me your planet.

  • Freaking AMAZING

    one of the best videos TED has put out yet !

  • Yes it's awesome. Makes me little more angry on myself for being so lazy in high school and at University. All we need is more sensors, more data, more connectivity and more transparency. With enough data and a little time people eventually come up with clever algorithms.

  • Don't be too hard on yourself, you are a mere 1 outof 100 billion people who have ever lived.

    There's a lot of blame to share around.

  • ;) but that's the only life I would have

  • OMG I luv this video....hope it has nothing to due with my lack of sobriety right now...awesome

  • Loved it. Though the talk was lacking cohesion a bit it was technical enough to talk specifically about some aspects of spectroscopy. Nice to learn something. :D

  • Long range sensors detect life. This is straight out of Star Trek!

  • like this?

    watch?v=dWBmaKk32fE

  • I see this more as a question of where is life than if..

    Given the distances involved, knowing where is paramount.

    Given the probabilities (infinite) it has never been a question of if... at least for me.

  • Brilliant.

  • If in 5 years we can detect stars and detect what ever small form of life, then not only must the galaxy be teaming with life, but the chance of intelligent life being out there would be almost a given.

    We need to settle this.

  • Very clinical, this type of data collection and analysis.

  • Very cool.

    TED always has interesting vids.

    Bravo!

  • ARECIBO!

  • hehe......i like it.

    SETI vs Cosmic Miracles....Awesomed.

  • WOW!! TED is so amazing, you never hear about things like these really, they're only mentioned on the side in news and then more attention is given to petty unimportant things. I adore TED!

  • I strongly believe that crop circles are made by people ;)

    Also UFOs as we see them on movies or on tv-news are made by people!

    Actually,in my opinion,there are not UFOs made by aliens!

    They haven't found life similar to people - at least in size - out there yet!

    I assume that by life we also mean micro-organisms!Such life may exists!

  • Wow!

    Look at all those thumbs down and yet only one response from someone.

    Thanks goddess for the reply,

    I imagine that the evidence will incrementally increase. I was once a 'not sure' person. Thankfully I never was a person 'certain' of nonexistence.

    Nobody anywhere in any stage of evolution can deny something that they do not know. <That is the truth

    Like the term UFO is to UNIDENTIFIED, Garik can also tell you that he doesn't know. Does that make it impossible for life anywhere else?

  • Of course I am not saying that life out there does not exist!I can't Know and I can't be sure either!That's right!But I am talking particularly about what tv shows!I believe that those UFOs as they present them and those crops exist but they are not made by aliens!There are a lot of political reasons to make us believe that!I've once heard that UFOs seen by so many people are military weapons presented as aliens' means of transportation!

    What's your opinion about that?

  • There is always that possibility for sure,

    As the military is concerned, UFO's called 'foofighters' outmaneuvered easily the old prop planes of the day.

    There is also a video out there somewhere showing a crop circle being made in just moments and little objects circling the area above. Whether or not those are military one can only suppose I guess. It would seem odd though that the messages are more to the contrary to ignorance, hate and warfare as the military.

  • You are completely comprehendible and I think I agree with you!We should be more open-minded and not so absolute especially with not proven scientific issues like this!

    Thank you for answering to my message!We were given the opportunity o exchange our opinions!This rarely happens on youtube!

  • Life out there exists! Once you understand how evolution works, and once you know that there are trillions and trillions of planets, the answer to that question is not as much important. You know the answer is yes. What becomes more important is the following question: Is there intelligent life on a planet/moon that can be reached in one life time of a human

  • I believe that life out there exists but I doubt that they have come to earth with UFOs!

  • i would argue that question is completely irrelevant. I think a better question is...can we build a bomb that will kill the intelligent life of a planet and make it habitable for us so that our children will have a place to live when we destroy earth or when our sun dies, and will our AI slaves protect us as we rest in stasis for the journey? (i'm just kidding :) )

  • i think the better question than that is do we deserve to survive

  • Comment removed

  • no offense, but that is the dumbest thing i have ever heard. to deserve survival is antithetic to the very nature of survival. the standards of deserving anything is a human construction and we would not be able to recognize the rubric of another power's standards of any being's deserving of any right, especially life. therefore, in my opinion, to have survived at all is to have been deserving of survival. so my answer to your question is...YES, we do deserve to survive, given we achieve it.

  • point taken, but i still dont like humans, they consume and destroy, like a virus infecting spreading and destroying its host, but i suppose viruses deserve to live just as much as any other self replicating molecules, i just personally hope either we learn some self control or die out before we kill our host

  • What a limited world view.

    Destruction, is that all you see? I just see humans moving a bunch of things around.

  • i dont think i really need to defend myself in my views, if you are under 30 you may live, but you will be witness to the death of more life than one can comprehend, and then you will understand, this is of course assuming stay the current course, if we got our act togather and started behaving responsibly we could probably save our own asses, i just dont personally see that as likely

  • I'm sorry to tell you this, but your hatred of humanity, according to the best psychologists, is a projection of your own self-hatred. I think you should listen to Michael Jackson's song "Man in the Mirror." TED makes me happy because it lets me know people are thinking about our effect on the earth and working to do something about it. You should connect with the good that people are doing in the world, and seek to effect a positive change from there. Don't live hating life, or your species!

  • i like this dialog we are having i always like any meaningful dialog! im afraid i dont "hate" my self i dont particularly like some of the things about myself much needs improvement but thats what life is for, the average man i meet however is a very different story, there is good in the world you are correct but its just a matter of statistics, gah its such a complex issue and im out of room, humans have potential but we need to make MANY changes before we deserve this planet.

  • David Sereda the UFOlogist? Well, I think TED is kinda about more, hmm, sane science.

    Oh, and I dare you, I DOUBLE DARE YOU to call me close minded!

  • You're close minded.

  • wow dude wow. Spectroscopy is obsolete? David Sereda lol. R u serious? He's a complete joke.

  • It's hard to take your comments into consideration since you have no friends, no videos, no favorites, and no subscriptions.

    You bad mouth that which you haven't researched.

    That qualifies as Troll.

  • i have researched him in the past when I first heard his bs claims.

    I just looked at the book you recommended and it is full of pseudoscientific garbage.

    He claims to have found the secrets of the quantum reality, yet he never mentions the Heisenberg or Schrodinger equations or what magical mathematics he has used to dicover these "differentials." He doesnt even appear to know what a differential equation is.

    You badmouth spectroscopy without doing any research. You sir are the troll.

  • You obviously haven't researched anything.

    I wish you well.

  • Where has he been published? By that I mean scientific journals not self-published e books.

    Who are these emminent PH D's who are so excited about his work?

    Why does his book include no citations?

    How can u possibly take him seriously?

    Did u buy some of his "Universal Balance Quantum Vibrational Jewelry?"

    Did it "increase your body voltage to much more holistic levels?"

    Is that why you like him so much?

  • Spectroscopy is how the planets are found, Its not obsolete at all.

  • Hi Verbz,

    Just like 'man cannot break the speed of sound' and other once amazing 'impossible' dreams, a time comes of realization in the possibilities.

    The membrane that you find others not noticing is just that.. The realization of possibilities. Once the palm strikes the forehead, they are a runaway god thyself

    In order to find, one must be open.

    That is an evolution in itself. Like the saying...

    "Eliminate all other factors, and the one which remains must be the truth. "
