11:33 am
headlines more news for you here on out is era also the stream next. ok you know what listerine in today's episode we also the question all humans alone in the you know this. is a professor of science at harvard university he joins us to talk about that kid a subject plus his new book extraterrestrial the 1st sign of intelligent life beyond us i have been reading this book from my research i started to turn down the
11:34 am
pages whenever i found anything interesting every other page is turned down i know you will have questions as well jump into the you tube comment section and you too can be part of today's discussion the reasons for me to buy this book basically it's like brain candy it's like junk food for the brain because there's always this nagging question what is out there we may never know but to have these thought experiments. has always fascinated me has been to me ever since i was a child i'm very hard years old now so i'm going on far but i still have sirens. it keeps the mind going and it keeps me wondering and that's where this comes into play it still keeps me wondering it doesn't have all the answers but it is food for thought. that's one way to make i guess smile professor loaf welcome to the stream
11:35 am
so good to see you. think don't kill write your book fall who is it. well thank you for having me i wrote the book for the young generation who i hope will occupy the horrors of it could be me in the future because young people do not carry a prejudice they don't carry biases they're not a patch to their ego as much as senior people are and frankly i told the publisher that if the person around the world would decide to become a saint is this after reading my book i would be satisfied it so happened that a couple of weeks ago i received an email from malawi africa from a woman that said the your book is great i'm contemplating becoming an astronomer after reading it and that made me satisfied already there was another one from columbia in latin america an undergraduate student who said they're reading about
11:36 am
your work change my life there was another one from a lawyer in palo alto who said similar things on. i'm quite satisfied the facile i'm looking at an article that you've read why do we assume extraterrestrials might want to vincent us so here's the question that a lot of people are wondering what and you want to in your book are we alone. right and that my suspicion is that we are not in fact that thinks like us existed for billions of years because most stars formby disappears before the sun and that the sun is that depict star and heart of the sun like stars have a planet the size of the earth roughly at the same separation so if you arrange for similar circumstances you might as well get seen our outcomes i don't think that we are special i don't think that we deserve special attention like many other people
11:37 am
who think you know when my daughters were young they were torment they thought very highly of themselves they thought that they must be you know the smartest in the world that they are the center of the world but then when we took them to the kindergarten they realized there are smarter kids around and our civilization will be much sure once we meet others we tend to think very highly of ourselves you know the ancient greek philosopher ari startled suggested that we are the center of the universe and people have believed him for a 1000 years and there are local paralegals and go you will realize that the earth moves around the sun and it still took a while before people accept that. i think you know we are not at the center of anything and we should look out and find others and just looking hair has not his saying here is what she knew right now and says of course there is intelligent life beyond earth how could we prove. what i am wondering though professor is
11:38 am
at exposure to science fiction of a mental wards and how that impacts even how insane how scientists feel the idea of extraterrestrial life what does that. right so science fiction i think plays a very important broadly in expanding our imagination as to what we might expect out there i have a problem with most of the storylines in science fiction i'm not a fan of science fiction i'm a fan of science or fiction separately but but they do value the fact that science fiction expands our our horizons the reason i don't like many of the story lines is because they violate the laws of physics very often but there are other scientists because of that tension of the public to science fiction and to reports about and they did it but flying objects and so forth they shy away from discussing this topic they say you know it said to popular 1 are it's controversial we don't want
11:39 am
to discuss it at all and my point is simple you know if you go back to ancient history there were people claiming that the human body has a soul and that we should not engage in anatomy and imagine if scientists would say all the subject of the human body is controversial some people claim it has a source some not and we don't want to discuss it just like the response to do science fiction what would happen with modern medicine where would we be i think in fact science has an obligation to attend to a topic that is of great interest to the public and clear it up using the same effect method using equipment telescopes that we have are we the smartest kid on the block you know that's a very fundamental question christopher shop has a question for you professor how many said how long. i mean huge fan of yours and i
11:40 am
believe that you're inspiring a generation of scientists to actively. curiosity out statement from the scientific community my question relates is saying actually may now u.s. government is actively investigating it is and is taking the phenomena seriously happy what is your opinion all you have is and. by the u.s. government to help them nervous to gay sions what would you respond city. yes that's an excellent question and what they think we should rely on is really the very best ecommerce an all of your sensors that we have a car hands right now rather than on or the reports from the pentagon that they're being declassified because they were not using the very best instruments and are based on partly on their eyewitness testimonies it's obvious why the u.s.
11:41 am
government was classifying these reports because there was always the concern that they might represent the chronology is that other nations possess and that poses and national security risk but them from the point of view of science what we would like to understand these are there are unusual phenomena that represent perhaps something else and for that purpose or we need to do is deploy the very best cameras and all of your sense source in the same locations and record everything we see you know science is about reproducibility of results you have to reproduce results in order to believe them there is their own biblical story of them abraham that. heard the voice of god and the the talking to sacrifice is only son isaac and then you know if abraham had the cell phone on with
11:42 am
a voice memo up equal have pressed the button and recorded the voice of god and then we would all believe it but given the fact that he didn't have a cell phone we have to decide whether we believe this testimony or not and i think you know it's much better to focus on how we get reliable evidence in the future rather than look at documents that were based on or the quick meant and i'm very open minded the family asked to lead a group of people that will perform same difficult experiments in the same locations recording the sky and looking for unusual for now. i would be very interested in checking this out you know it's just the way we do science we look for every day as we are guided by theirs and we should not be guided by bridges i love that you talk about looking for unusual phenomena which brings me to something that was spotted in 2017 that some think is on my laptop surrounded by a little blue so call professor for those of us who are new to this tell
11:43 am
us what you're seeing what they're seeing and what your hypotheses is that this is . yet this is an object the 1st one that was discovered near the earth that came from outside the solar system it's sort of like finding an object in your backyard that came from the streets and it may have taken a long time to get here and he saves you the triple for going to the street then figuring out what's going up there and this is the very 1st one that we not these you know our vicinity it was given the name award one because it was discovered by a periscope in hawaii and there are more and more means to sculpt in the hawaiian language and at 1st the stronger merced thought well it must be just like the rocks we have seen before in the solar system either a comet or an asteroid the problem was that it didn't have any cometary taters no
11:44 am
gas or dust around it and also as it was spinning around every 8 hours its brightness changed by a factor of 10 and that implied that it has a very extreme shape most likely flat. pancake shape so it's just like a piece of paper tumbling in the wind and then it exhibited an excess push away from the sun that can only be explained in terms of reflection of sunlight pushing it and in september 2020 we saw another object that exhibited the same kind of push by reflecting sunlight and not commentary tale thus are the battle ject which was called 2020 s all is actually a rocket booster that we launched in 1966 and their mission and we know that we produced it artificially the question is who produced or more more. sale
11:45 am
let me say that question back to here because this is a 5 asking such a big scientific debate around you asking who purchased a more her because you are saying possibly professor fill in the blank an alien civilization and the can a logical civilization you know for the past 70 years we've been searching for of your signals and we didn't get any that's just like trying to have a conversation you need the counterpart to be alive we cannot have a phone conversation with the mayans with the mayan culture because it's not around anymore but we can find evidence that if they existed in archeological digs we can find relics that they left behind and in much the same way we can do space archaeology we can look for equipment but was sent into space just like we sent voyager one voyager to new horizons and it's floating audience space every now and
11:46 am
then there would be a piece of equipment that we would discover in our city it's just like walking on the beach and every now and then seeing a plastic bottle among the rocks that they're naturally produced and of course the way to tell the difference between a plastic bottle and iraq in space is to send a spacecraft that we come close to it and take a close up photograph they say a picture is worth a 1000 words any in my case a picture is worth 66000 words the number of words in my book seth professor is out of extremely article right now but you started up huge storm of controversy and other scientists said with quite a lot of determination that you are so loose wrong in your hypothesis let me introduce you to one of them this is captain. and the
11:47 am
representative of the after gumbo community and myself and many others disagree with dr logs assessment of more and more as an actor terrestrial space probe the science just isn't there yes the moon boy is from interstellar space yes it has an odd shaped yesterday experience gravitational acceleration and a higher suns but all of these things have natural when ations collision between fine terry bodies are very common in the universe and you're going to outgassing had been shown to be a buyable explanation for why more accelerated and the path by our science so what i think we're really looking at is just a visiting chunk of another solar system. right so there were various suggestions that were more ways than natural object and the latest one among them is in nitrogen iceberg hypothesis that it's an object made of pure nitrogen and before that there was a suggestion that it's an object made of pure hydrogen and we just can't see the
11:48 am
cometary tape because it's transparent for hydrogen the problem is that we showed it in a sink depict paper that it would have operant very quickly an object of the size of a football field will not last very long and can survive the journey for nitrogen iceberg and that's their plot this is that was published just a week ago i'm currently writing a paper showing that you just can't make enough of them to explain all more and more up there would be too few but all this of magnitude compared to what you need from a population that whose members are abundant enough to explain an object like that because if you think about it their view is that it's a chunk of frozen nitrogen and that you can make on the surface of planets like brutal or which are you know a small component in the solar system and so the chance of that happening is really
11:49 am
small if you will chip off the surface of a planet like brutal and that you have enough brutal for every star what you need as thousands of pluto's for every star such that you have enough chunks of nitrogen to explain or warm we're up and there are other eye porpoises that maybe it's a cloud of dust particles but these a 100 times less dense than air the problem with that is as it gets close to the sun it would be heated by hundreds of degrees and then it would not maintain its integrity so on all of these natural explanations involves something that we have never seen before. and my point is simple if we invoke something that we've never seen before we must keep on the table the possibility that it's our professional in origin and the fact that this is controversial just reflects on my colleagues not on me i'm just following the standard thing to fit procedure where i put all possibilities on that they both without prejudice professor i feel like i just
11:50 am
experience what it's like to have to hear trash talk from a professor of science at harvard university there has been a lot of controversy that continues a new theories that your work has inspired one of them in a and you just mentioned this one this is from the smithsonian magazine or they share this new theory suggesting that more and more is a nitrogen ice pancake we spoke to a professor of. astrophysics who actually subscribes to this now i would love for you when i when i play this to explain what he's asking and challenging iran before you reply to it because it's a little complicated have a look have a listen i've been funded by nasa for a long time to help devise strategies for looking for ilion life on exoplanets and it's by trying to understand the geochemical cycles on these planets and eliminating false positives and every astronomer i've worked with we're all
11:51 am
confident that we're going to find evidence of alien life maybe even within our lifetimes but we know that we're going to do this by eliminating false positives in the same it's all normal we have to eliminate all the natural explanations 1st no responsible scientist is going to look at a normal and say it's alien technology if there are reasonable natural explanations like an end to a scrag minute off of the trunk of the next. yes. steven is one of the author or so of the recent 2 papers that were published last week arguing that maybe or more is a chunk of pure nitrogen and for this scenario to work you cannot allow carbon for example to be a source she added with that the iceberg because the spitzer space telescope would very tight limits on any carbon based fuels in the vapor that comes came out of fear or what if it thought it so there was no carbon and the claim is
11:52 am
ok maybe it's just pure nitrogen and one environment where you find pure nitrogen with live very little carbon is the surface of brutal very thin veneer you know less than a percent of the mass of blue dog on the surface is made of pure nitrogen so that proportionally ears that you just scrape off the surface of pluto like planets around other stars you create chunks and what we are seeing as the 1st interests that are objects or more and more are was one of these chunks the think that you have to keep in mind is we have never seen and nitrogen object in the solar system saw we have the saw cord or plug of you know about a 1000000000 objects larger than manhattan island in this in the periphery of the
11:53 am
solar system and all thousands of those examples of objects that we saw from the environment of the solar system were made off i see rock you know the kind of things we find on earth rocks including carbon including water on their surface in the form of ice and that's what we've seen thousands of times we've never seen and nitrogen pure nitrogen chunk and then get you know sleet some. thing that we have never seen before and we're supposed to believe that more than anything artificial and dismissed artificial possibility based on that and the other thing is you know carbon and nitrogen are produced in stars by the same process and usually you know there is one example of a nitrogen rich comet that we have seen that the authors of the speaker are mentioning and that one actually shows also evidence for carbon so i rest my case whenever you know typically you get carbon together with nitrogen and why would you
11:54 am
scrape off the surfaces of pluto like objects and create the bust majority or being the star object this way or it is of special fractional being does that our object this way rather than have the majority of them being rocks like we find the source is the problem saying is we look at our backyard that we see iraq's then you tell me all in this street there are very different type of thought jets actually nitrogen pure and i said ok maybe you know that's a possibility but it's certainly not an appealing possibility let me show our audience this path check this is galileo italian astronomer it was a physicist who was a philosopher as well going up against the church the church was furious at his idea of what our solar system looked like he was right they were wrong you mentioned this in your book a you're a modern day galileo. well that's
11:55 am
a good question and you know it really is the bends and the response of the community i am just just like busted but players keep my eyes on the ball not on the audience i don't care how many likes a head on twitter and what the response of you know the personal attacks that people. launch at me that really is irrelevant because we have we have to look at the evidence and if it looks anomalous and the arc of the show origin appears to be more likely than things that we've never seen before then i advocate for that once we get more evidence i basically say let's take a photograph of the next object that would be looking us we are still more in what we would learn something new or no matter what because even the natural origin ideas like the one we just heard about the nitrogen ice berg even they talk about something that we've never seen before so there must be factories of objects that we've never seen before let's figure them out by getting more evidence that's my
11:56 am
advocacy and the only reason we would not get that evidence is if you listen to those people that say you know it's always rocks it's never illions to me they remind me of a cave men that plays with rocks all of his life and then present it with a cell phone and arguing a certain one must be just the shiny half f.s.a. you have just insulted so many of your peers and colleagues i am enjoying this immensely sound when our new chief says remaining skeptical is so important which says if we know the truth about aliens it will change everything that we fly and one more thought here and that is the idea of from 70 he says what should we expect from the future while at church a restaurant life ever come to feel some of us here on our earth and that thought is a very quick thought professor because we have right at one end of the show and i'm going to give you one minute go ahead it's very important it's
11:57 am
a very important question and that. recall fermion famous physicist where he's everybody you know i think it's presumptuous us to expect them to visit us we should go out and search for them we are not that significant we're not that important it reminds me of the friends of my wife when i met her they were waiting for prince charming on a white horse to come and make their marriage proposal and it never happened we should expect that you know a lot of others to appreciate us we should go out and search and you know frankly we are born into this world like actors good on a stage we felt the script the 1st thing to check is are there other actors around and we ask them what the plays about thank you so much professor. extraterrestrial the 1st sign of intelligent life beyond earth and that is his new book string the controversial enjoy digging into that and then come to your conclusions professor thank you for being on the string today really enjoyed your company side and i'll
