The Fermi Paradox — Where Are All The Aliens? (1/2)

  • The Fermi Paradox — Where Are All The Aliens?

    6:22

    The universe is unbelievably big – trillions of stars and even more planets. Soo… there just has to be life out there, right? But where is it? Why don’t we see any aliens? Where are they? And more importantly, what does this tell us about our own fate in this gigantic and scary universe?

  • The Fermi Paradox II — Solutions and Ideas – Where Are All The Aliens?

    6:17

    Where are all the aliens? The universe is too big and too old, why have we not met aliens yet? Do they live in computers? Were they wiped out by an ancient super intelligence? Or are we just to primitive to understand their motives? Whatever the answer is, it is incredibly important for our own future.

  • The Fermi Paradox - 10 Mind-Blowing Explanations

    7:40

    A lot of this came from - where else - an awesome article on Wait But Why.



    Here I take a question by Mark Lott, asking why, with all the billions of stars out there, we haven't been able to detect a single intelligent civilization out there. This is the Fermi Paradox.



    The universe is impossibly big. Even our own galactic backyard has 10,000 stars for every grain of sand on Earth. Shouldn't it be teeming with intelligent life? If this sounds bizarre, the reasons science has come up with to explain this are freaking bananas.

  • Why Have We Not Found Any Aliens? - with Keith Cooper

    51:38

    After six decades of examining signals from space, why have we yet to discover evidence of extra-terrestrial life?
    Keith's book The Contact Paradox: Challenging our Assumptions in the Search for Extraterrestrial Intelligence is available now -

    For the past six decades a small cadre of researchers have been on a quest, as part of SETI, to search for extraterrestrial intelligence. So far, SETI has found no evidence of extraterrestrial life, but with more than a hundred billion stars in our Galaxy alone to search, the odds of quick success are stacked against us.

    Keith Cooper explores how far SETI has come since its modest beginnings, where it's going and the assumptions that we make in our search for extraterrestrial life.

    Watch the Q&A:

    Keith Cooper is a freelance science journalist and editor. Since 2006 Keith has been the Editor of Astronomy Now, and he is also the Editor of Astrobiology Magazine. In addition he has written on numerous space- and physics-related topics, from exploding stars to quantum computers, for Centauri Dreams, New Scientist, Physics World, physicsworld.com and Sky and Telescope. He holds a BSc in Physics with Astrophysics from the University of Manchester.

  • The Fermi Paradox - Are we alone in the Universe?

    4:00

    The Fermi Paradox - Is there life in our Solar system?
    Is there life in our galaxy?
    Is there life anywhere else in the vast Universe??

    Given the the size of the Universe with an unimaginable amount of stars and solar systems....there has to be life out there somewhere....surely?



    Many of us have often thought......are we alone?
    Is there life in our Solar system?
    Is there life in our galaxy?
    Is there life anywhere else in the vast Universe??

    Given the the size of the Universe with an unimaginable amount of stars and solar systems....there has to be life out there somewhere....surely?

    In 1950 physicist Enrico Fermi asked this question amongst colleagues and quickly went to work on calculations on the probabilities of life existing elsewhere.

    Just in our own galaxy, the Milky Way...... which is thought to contain up to 400 billion stars.... Estimations suggest there are roughly 20 Billion stars composed just like that of our Sun.

    If just 1 in 5 has an earth like planet in orbit within the habitable zone, also known as the ‘Goldilocks zone” where it is not too hot or too cold, that would give us 4 Billion planets that could potentially support life....

    If just a mere 0.1% of these Earth analog planets do actually have life within them.... then this amounts to 4 million life dwelling homes.

    If just 0.1% of these planets contain ‘intelligent life’ comparable to humans....that gives us 40,000 civilisations

    And if just 0.1% of these civilisations we’re capable of space flight and like humans, are explorers who want to expand to other planets, then there will be 40 whizzing about in space around the Milky Way!

    And this is just from using low estimates.

    But the problem is.....we have ZERO evidence that these calculated probabilities are actually happening! And this is the basis of The Fermi Paradox.

    So where are they?

    There are many theories as to why we are yet to detect any other forms of intelligent life...and these include....

    We are the first to emerge with technology capable of transmitting and receiving communications across space and therefor it is currently impossible to make contact.

    Natural disasters such as super volcanos or large asteroid impacts are wiping out developing civilisations.

    Weather conditions and climates on other planets could be too unstable to sustain life long enough for sufficient evolution development.

    Their planet is poor on resources so may never have the ability to progress technologically.

    Other civilisations are choosing not to look outward.

    Maybe we are just not able to detect them through incompatible technologies, using methods and devices we have no understanding of.....or you could say....completely alien to us!

    Other civilisations that may have became capable of communication have already lived out their existence and no longer exist, possibly by destroying themselves through wars, or with much more powerful and advanced technology! But should we be able to see some form of evidence of previous existence in the cosmos?

    Maybe, just maybe we are a fluke, an anomaly, and are the only ones out there....anywhere!

    Or worse yet, we could have been created, physically or virtually, and are currently being observed by a super intelligent species hiding from us, just to see how we develop. We could potentially be some sort scientific experiment that could end anytime!

    It’s a scary thought.

    Whatever the truth actually is......we may never discover it.

    But that will not stop us from trying.

  • Where Is Everybody? - The Fermi Paradox Explained

    14:38

    Enrico Fermi once asked a simple question during a luncheon. 'Where is Everybody?'. Since then, scientists around the world have been scratching their heads to find an answer.

    Where are all the aliens? Are we alone in the Universe? Do Aliens Exist? If you ever look up at the night sky in awe, chances are you have had some version of the questions above.

    Many scientists believe we are not alone in the universe. It's probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone -- just as it did here on planet Earth. This basic question about our place in the Universe is one that may be answered by scientific investigations. – NASA

    The Fermi paradox or Fermi's paradox, named after physicist Enrico Fermi, is the apparent contradiction between the lack of evidence and high probability estimates, for the existence of extraterrestrial civilizations.

    In this episode of Journal of Things (s2e04), we are going to discuss the Fermi Paradox, Drake Equation and delve deep into the universe in search of the extraterrestrial lives, our place in the Universe, what the future holds for us, and various reasons for which we haven’t yet come in contact with other intelligent civilizations.

    Seeking new life beyond the earth is a fascinating, even romantic, branch of astronomy. One fascinating example of the work that has gone onto this area is the Fermi Paradox which highlights the disparity between projections and actual results and data.

    Joseph Silk is a renowned cosmologist who currently holds posts at three of the world’s top Universities: John Hopkins University, Le Sorbonne and the University of Oxford. Professor Silk is one of the world’s leading experts in theoretical cosmology, dark matter, galaxy formation and cosmic microwave background. Professor Silk’s studies of galaxy formation and his work on the dynamics of mass loss and the feedback mechanisms from star formation and evolution formed a highly significant basis for subsequent work in this important field. In 2011 he won the Balzan Prize for this pioneering work on the infant universe. You can find out more about Professor Silk by visiting his Professor page:

    Professor Silk's inaugural series for Gresham College is titled 'The Biggest Questions in the Universe'. In six lectures, Professor Silk will examine the earliest moments of the Universe; discuss the first stars and the future of the field as 'galactic archaeology' expands our understanding of the Universe. You can see all of the lectures on the website:

    Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 1,800 lectures free to access or download from the website.

  • Fermis Paradox and the Psychology of Galactic Empires | Matthew O´Dowd | TEDxTUWien

    23:45

    We now know that the Galaxy is full of potentially habitable planets. So why do we see no signs that any civilizations have come before us? Matt O'Dowd, astrophysicist and host of PBS Space Time, explains why Fermi's paradox really is so surprising, and he offers a new piece of evidence that may point towards the solution.

    Astrophysicist Matthew O’Dowd spends his time studying the universe, especially really far-away things like Quasars, super-massive black holes and evolving galaxies. He completed his Ph.D. at NASA´s Space Telescope Science Institute, followed by work at the University of Melbourne and Columbia University. Currently he is a professor at the City University of New York´s Lehman College and an Associate at the American Museum of Natural Historys Hayden Planetarium.

    A short documentary explaining solutions to the Fermi paradox.

    The Fermi paradox, named after the physicist Enrico Fermi, is the apparent disparity between the high probability estimates for intelligent civilizations, and the lack of evidence.

    In simpler terms, if we are so sure that they exist, then where are they?

  • Are we alone in the universe? Where are all the aliens? Fermi Paradox Solutions & Drake Equation

    10:23

    Do Aliens exist? Are we alone in the universe? Where is everyone? Fermi Paradox and Drake Equation: Where is everyone? You probably already know that there are more stars in the universe than all the sands on all the beaches of earth. In fact, Keppler data shows that just within our own Milky Way galaxy, there may be 10 billion earth-size planets orbiting sun-like stars in the habitable zone of its solar system.

    Physicist Enrico Fermi, in the 1950’s, asked why, given the vast number of potential planets with life, haven’t we been contacted by aliens yet?
    Fermi reasoned that any civilization could colonize the galaxy by building AI robot probes that could self-replicate as they journeyed beyond their home planet. Even though the distances between habitable planets are much too vast to be traversed in a human lifetime, the theoretical robots would have had millions or even billions of years to make the journey.

    This seems to be a reasonable assessment because when our instruments look out into the universe, we can see that the materials and conditions for life that are present here on earth, But the fact is that our instruments can see no evidence from all our observations of any tell-tale signs of intelligent life anywhere in our solar system, our galaxy or the rest of the observable universe.

    In order to detect the kind of signal that Fermi was talking about, that life also has to be super intelligent…One that sends out electromagnetic signals. And in order for us to detect intelligent life on other galaxies, that species would have to be a space colonizing species. Such a galaxy should light up unnaturally. So even having intelligent beings on a planet is not enough, because many intelligent beings have evolved on earth, but super intelligence – space-faring species, like us humans, only evolved only once over 4 billion year on earth.

    The Observation selection effect creates a bias in our thinking because no matter how unlikely super intelligence in the universe is, because it has happened here on earth, we are biased to think that it should be easy and can happen anywhere, no matter how unlikely it actually is.

    There are several features of our evolution that makes it reasonable to assume that we got here due to extreme circumstances. For example going from simple single cell bacteria to complex organelle-containing cells from which all complex animal life came took about 1.5 billion years on earth to evolve. But maybe the natural progression of such an evolutionary leap is on the order of 20 bilion or more years.

    There is no evolutionary reason for life forms to be a space colonizing species. There is nothing that it does to our species to help us eat or reproduce better. We don’t seem to have evidence that this intelligent life form will continue to evolve into a super intelligent life form like we did.

    We can look at the fermi paradox mathematically. The Drake Equation shows the many variables used to estimate the number of active extraterrestrial civilizations in the milky way galaxy.

    N = R Fp Ne Fl Fi Fc L

    R= average rate of star formation in our galaxy
    Fp = fraction of those stars that have planets
    Ne = avg number of planets that can support life per star that has planets
    Fl = Fraction of planets that can support life that actually develop life
    Fi = fraction of planets with life that go on to develop super-intelligent life
    Fc = fraction of civilizations that develop a technology that release detectable signs into space
    L = length of time that such civilizations release detectable signs into space

    Fi – is an utter guess, and may be an extremely small number. Fp is large, nearly 1, but our failure to detect intelligent life tells us that there may be a filter or several filters that prevents super intelligent life from emerging.

    There is a possibility that there is a great filter between where we are now and the beginning of earth. Or there is a great filter between where we are now and some event in the future that prevents intelligent life from colonizing the galaxy.

    This is why finding life on one of the other planets in our solar system would spell doom for us. Why? Because Finding a life form that evolved independently of earth on a planet in our own solar system, would mean that life is likely very easy to evolve. This would mean that we are probably staring straight down into the barrel of the gun that is about to fire in our face. The great filter – would be an event that is likely to spell the death of our civilization and technology. So let’s hope that there is no other life on our own solar system.

    There are theorists that say that aliens are keeping us like in an alien zoo and have conspired to make us unaware of it.

    The simplest explanation is that Intelligent life is very difficult to evolve. It fits all the evidence. But given the size of the universe, even if life is extremely rare, it can still be abundant.

  • Robin Hanson - the Fermi Paradox & the Great Filter - Are We Likely Doomed?

    1:13:09

    What's the worst that could happen? - 16 years ago Robin Hanson said: “Humanity seems to have a bright future, i.e., a non-trivial chance of expanding to fill the universe with lasting life. But the fact that space near us seems dead now tells us that any given piece of dead matter faces an astronomically low chance of begating such a future. There thus exists a great filter between death and expanding lasting life, and humanity faces the ominous question: how far along this filter are we?” :

    Post on SciFuture:

    Refuge Markets:
    Refuge Resorts:
    Galaxy Calc Shows Aliens:

    - The FERMI Paradox? Where are they all? Sagan said: “The universe is a pretty big place. If it's just us, seems like an awful waste of space.”
    - What do you mean by Great Filter - xRisk - what forms?
    - How is our society currently brittle - what kinds of things are likely to wipe us out?
    - What kinds of technologies/advancements in general would make humanity less brittle/more resilient?
    - how old are the earliest Goldilocks Zones?
    - What kinds of evidence for technologically advanced alien civs should we expect to see at this time? (in our light cone)
    - Recently SETI Institute Dr Seth Shostak bet everyone a cup of coffee that we would detect alien life within the next 25 years… advanced alien life? your thoughts?
    - Dr Seth Shostak also caused a minor stir when he proposed that it is much more likely if and when another intelligence is discovered it would be non-biological… what kinds of evidence for ET life would increase your estimates of human survival in the future?
    - how about an extinct alien civilization on mars?
    - Are we almost past the great filter? How far along this filter are we?

    Alternative Explanations
    - Rare earth hypothesis?
    - STEM theory - John Smart? Transcendence?

    - what does the current view of likely great filters tell us about what we should be doing to avoid these great filters?

    - sci fi stories that deal with the great filter?


    Robin’s talking points on the Great Filter:
    -1. Last step of filter, go very visible.
    0. Selection effects mislead track records.
    1. Early life out there is bad news.
    2. Selection effects make it worse.
    3. AI can’t be it.



    Ticket Markets (what could go wrong in the future?): &



    'Galactic Calc shows Aliens' (where is earth in the distribution of planets out there?):

    Combining standard stories of biologists, astronomers, physicists, and social scientists would lead us to expect a much smaller filter than we observe. Thus one of these stories must be wrong. To find out who is wrong, and to inform our choices, we should study and reconsider all these areas. For example, we should seek evidence of extraterrestrials, such as via signals, fossils, or astronomy. But contrary to common expectations, evidence of extraterrestrials is likely bad (though valuable) news. The easier it was for life to evolve to our stage, the bleaker our future chances probably are. :

  • A Physicist Has Explained Why Weve Never Seen Aliens

    10:26

    Recently, astronomers were able to map about 1 billion stars around us. Sounds impressive, but that’s less than 1% of the total stars in the Milky Way. So it’s statistically impossible for us to be the first intelligent species in the galaxy! But if there absolutely should be developed civilizations in the Universe, then where is everybody?

    We’ve been looking for about 70 years for any sign of extraterrestrial life, or any communication from little green men or whatever they are. And we still have absolutely nothing to show for it. How is this possible? That exact question was once asked by famous Italian physicist Enrico Fermi, the creator of the first ever nuclear reactor.

    Music by Epidemic Sound

    SUMMARY:
    - The Fermi Paradox has a lot of potential solutions. The first group is all about two big ideas: The Rare Earth Hypothesis and the idea of the Great Filter.
    - Can you imagine, how much would have to fall into place for an advanced civilization to rise to our level? Let’s just say we hit a jackpot in all categories.
    - Jupiter is hugely beneficial to us. Its mass attracts all the space debris, meteors and comets like a giant vacuum cleaner. If not for it, the Earth would be bombarded with giant space rocks all the time.
    - The size of our planet and its speed of rotation make an optimal day and night cycle. Our planet has lots of chemical elements, crucial for the development of life.
    - Eventually, it’ll have beings that look at the skies from time to time and think that they probably aren’t alone in the Universe.
    - But these intelligent folks still won’t be the ultimate winners of this universal lottery. They still must develop technology to go into space and send signals.
    - Another solution is far more optimistic. Aliens are out there, but we just can’t communicate properly with them.
    - What if they went through a significantly different route in technology; one that’s not even comprehensible for us. What if they did so because their own communication is different than ours?
    - The next solution is far more possible. In basic terms, it proposes that we aren’t alone, but we are the first to advance our civilization to the needed level of technology.
    - There’s also a funny argument that aliens are so unlike humans in their way of thinking that they simply don’t want to communicate with anyone else.
    - And finally, the solution all fans of UFOs want to believe in – they really are common in the galaxy, but they can hide from us and maybe they’re already around us.

  • David Brin on the Fermi Paradox

    3:24

    Author David Brin comments on why we haven't found any extraterrestrial neighbors yet.

    These comments are from an interview conducted on April 7, 2013.

  • The Fermi Paradox Hindi

    7:52

    Hello friends in this video we will watch the fermi paradox where are all the aliens why aliens had not come till the date to the earth or not send any of the signal.So where are all the aliens
    the possible reason for this can be
    Extraterrestrial life is rare or non-existent
    No other intelligent species have arisen
    Intelligent alien species lack advanced technology
    It is the nature of intelligent life to destroy itself
    Periodic extinction by natural events
    Intelligent civilizations are too far apart in space or time
    Civilizations broadcast detectable radio signals only for a brief period of time
    Human beings have not existed long enough
    We are not listening properly
    They are here undetected
    So friends watch this full video till the end

  • Where Are All The Aliens? The Fermi Paradox

    4:37

    Click to tweet: . There are sextillions of stars in the Universe, quadrillions of which are like the Sun and around many of these orbit Earth-like planets. Given all that, where the heck are all the aliens? This thought is called the Fermi Paradox, first voiced by the physicist Enrico Fermi over half a century ago. A number of answers have been given:

    1. There is something like Star Trek's Prime Directive in force (Star Trek and the Prime Directive are copyright Paramount - no infringement intended). This is the idea of an ethic preventing interference with our civilisation. This is a somewhat elaborate idea which follows from a lot more assumptions than the others.

    2. There are no aliens and we are alone in the Universe, possibly because Earth-like planets are rare. I was planning to say a lot more about this, so i'll probably do a separate video on this. The idea is basically that the conditions which enabled a technological species to evolve here are very rare for carious reasons. This is known as the Rare Earth Hypothesis.

    3. They are here, but in disguise. That is, it's possible that aliens visit this planet all the time but given that their technology is capable of travelling interstellar distances, it is also clearly going to be capable of making itself invisible, or alternatively, that there are simulacra of human beings among us. In fact, it has occasionally been suggested that I am an alien. Heaven forfend! UFOs (flying saucers) are problematic for this reason, and therefore i believe most of them are either misidentifications of well-known phenomena or secret military aircraft. If they wanted to be seen, they would be.

    4. It's a self-fulfilling prophecy. Each civilisation notices the suspicious silence of the skies and acts accordingly out of caution.

    5 (Am i keeping in step with the video numbers here?). Civilisations are short-lived because they do something to wipe themselves out, like steer an asteroid into orbit and accidentally crash it into their planet, build technological systems so complex that they can't control them, wage nuclear war, suffer from the Grey Goo Scenario and so on. Therefore we don't have long to spot them and will very shortly go the way of the dinosaurs ourselves.

    6. They don't care, either because they're not like us, they're enlightened spiritually and have no interest in such worldly things or they spend all their time on an extraterrestrial equivalent of Facebook in cyberspace.

    7. We're in a nature reserve and are being observed by aliens. This is a kind of combination of (1) and (2).

    8. We've not been looking long enough or our technology is incompatible with their signals.

    9. It's too expensive to travel to other star systems - maybe we could hitch-hike?

    Ten. Sorry, i can't remember. Clearly i'm going to have to come back to this.

  • The Fermi Paradox and the Rare Earth Hypothesis

    46:01

    Enrico Fermi once asked, 'Where are all the aliens?' With trillions of stars and planets out there, we really ought to have seen them by now... if they are there. The Rare Earth Hypothesis seeks to explain the missing aliens by pointing out just how difficult it is to produce life, especially intelligent life, in the short time window of about 5 billion years before a star like the Sun turns into a red giant and destroys its Earth-like planets.

    ABOUT ALPHATUCANA
    This channel is about 'waking up' from our matrix-induced slumber, and about leaving the World a better place than we found it. For most of us, our powers and motivation are strictly limited. We are fundamentally alone in a vast and mysterious Universe, but In the struggle to survive, to 'succeed', or to just get by, we sometimes forget the bigger picture, and we sometimes forget to just relax for a while and remember what an amazing World this is. There is plenty to look at: science, Nature, society... And there are plenty of games to help us get away from it all... So on this channel, I vlog about science, Nature, enlightenment, current affairs and much else besides, I upload sightseeing videos showing London, England, or my holidays elsewhere, and I upload gameplay videos. So why not join in for a while and see what you think?

    POSTING SCHEDULE
    This depends in part on whether I have had time to record videos in between going to work and living the rest of my life! Usually it runs like this:
    - Sat or Sun: a vlog or sightseeing video at midday (UK time).
    - Gameplay videos: pretty random - typically at midday on weekdays, but not all the time.
    - If I have something extra to post it usually appears at some random time :) I may livestream occasionally too.

  • Das Fermi Paradoxon II – Ein paar Ideen – Wo sind die ganzen Aliens?

    6:09

    Wo sind die ganzen Aliens? Das Universum ist so groß und so alt – warum sind uns noch keine Aliens begegnet? Leben sie vielleicht in Computern? Wurden sie von einer uralten, superintelligenten Macht ausgerottet? Oder sind wir einfach zu primitiv um ihre Motive und ihre Lebensweise zu begreifen? Egal was die richtige Antwort ist, sie ist unheimlich wichtig für unsere eigene Zukunft.
