Alien worlds and extraterrestrial life - where are they?! | Brad Gibson | TEDxHull

  • Опубликовано: 5 июн 2017
  • Do aliens walk among us? Have we been
    visited before? Are they out there watching…
    listening…studying us? And if they are out
    there, where might ‘there’ be? Our Milky Way
    can be a nasty and inhospitable place for
    life to develop, but all is not lost. There are
    some very unique and special places hidden
    amongst this hostile environment where the
    building blocks for life might be just right for
    extraterrestrial life to flourish.
    Brad Gibson is a Professor of Astrophysics. He completed his MSc and PhD at the University of British Columbia, building the world’s first Liquid Mirror Telescope Observatory. He was responsible for using exploding stars to determine the expansion rate of the Universe (as part of the Hubble Space Telescope Key Project), for which his team was awarded the Gruber Prize in Cosmology. Clearly a busy guy, he also discovered the first evidence that our own Milky Way’s nearest neighbours were being cannibalised by our Galaxy. Who better
    to answer the question: alien worlds and
    extraterrestrial life - where are they?!
    This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at

      I am no expert, so take this as you will. Just based on the unfathomable size of the galaxy, let alone the universe, I'd say there is not just one circumstance similar to our own, but MANY. The problem is, we still don't exactly know what the "catalyst" if you will, for life is. The amazing thing is life began churning very early on Earth's timeline. That could suggest the barrier to life is low and would happen frequently throughout the universe. If a planet has water, and there are thermal vents that produce heat (energy), and we find life there, we can assume it is very common.

    It is interesting how diverse conclusions are, but an inventory of the real evidence by reasonable minds makes the perpetuation of uncertainty on the subject matter seem propagandistic. Quite simply, I think there is a statistically higher chance that one evidence for engagement by foreign intelligence is true after surveying the testimony and evidences of people who do not seem to harbor a fear of smallness or a need to serve their vanity.

    If the whole universe is really just a vast infinite space of consciousness then this guy isn't even real and what he is saying doesn't even exist. Science can't even explain what consciousness is in the human body so understanding that the entire cosmos is just a living entity of consciousness and we are all a part of that.......well it really makes this video indifferent. And why was this titled alien worlds and extraterrestrial life when they are mentioned briefly at the very end? Mr. Gibson is a very knowledgeable professor and I respect his accomplishments and would love to hear more of what he has to say but the subject matter in this particular video feels speculative to me but that could be because I believe somethings to be different but I always keep an open mind and appreciate the information other people are willing to share.

    I’m not sure how you can claim a pragmatic standpoint when we’ve not even examined a fraction of 1% of the known universe. You lowballed the number of stars as well as the number of planets... and failed to account that nearly half of the galaxy’s mass is in fact outside the visible arms in the “haze”.
    I’m not going to claim your assertions invalid, however... I will say you come across as very limited in your awareness of our ignorance.

    Someone once said "No chance.. zero that we will ever be visited.!" Physics does not rule out interstellar travel via wormholes, warp drive etc.. I have seen crafts and they did things that far surpass our current capabilities so either we have this advanced tech or we are being visited by extraterrestrials.

    Brad, exactly which part are you disappointed in? I thought that this was extremely insightful to the layman. So, a while back... I brought forward the thought to friends regarding the changing of climate on Earth (I am not a scientist, just an observer that tries to engage in critical thinking) that our solar system (as it travels through space) could be affected by non local gravity, charged particles, solar activity, and also that we are actually travelling as a solar system along this "spur" that can possibly interact with other phenomena (that used to occupy that space), etc. Also, knowing how orbits are not perfect (Milankovitch cycles for example describing the collective effects of changes in the Earth's movements on its climate over thousands of years.) and that the earth and the moon essentially slightly wobble as they circle the sun (there is an excellent gif that demonstrates Pluto and its largest moon's effect on the other - regarding the recent flyby). And there is Orbital eccentricity, Apsidal precession, Axial precession, etc. which MUST allow for variance over centuries given that the galaxy as a whole is constantly pulling on our local group... especially as spiral arms are affecting us over millions of years. My point is, that our galaxy does not spin perfectly (there are constant variables including the tug of Andromeda Galaxy and the Magellanic clouds) plus stars which eventually turn super nova (and their energy being expelled in a large event and eventually becoming gravity wells... which WILL affect us locally by minute variances (VERY small variances to be sure) but over millennia... would account for solar effects on our planet (specifically, the solar wind when the sun is more active and less active). But I am blathering now..... my point is, how do climate scientists ever hope to correctly model these additional effects on this Earth as they are unable to quantify those effects? As far as I am concerned, there is not one climate scientist who can correctly assess climate change due to these external variables. And I also subscribe to the Patrick Moore school of thinking regarding CO2's actual effect on climate change (there is no direct correlation due to variances unexplained by Ice Age levels of CO2 plus the example of ice cores giving us plenty of data regarding the past climate/CO2 levels) and given water vapor affects the globe far more and that the earth is slowly greening which actually benefits mankind regarding crop production for the now over 7 billion souls on this planet). And that I believe most climate models don't have enough quantifiable data from the Oceans to give us anything reliable to hang our collective hats on. But what do I know, I only have a High School diploma regarding my CV. Anyhoo, I'd love to see your updated version of this TED talk and what you think now with additional input from the scientific peanut gallery. ;)

      I just wish that I would have had a secondary education that would have allowed me the opportunity to pursue scientific thought in a meaningful way. I certainly can't even engage anyone in this field as my obvious lack of education exposes me after the first sentence uttered (at least it does with my scientist cousin who is a GIS Analyst with the UW Climate Impacts Group - University of Washington). Alas......

    I mean you can make up variables about our life, and what are the building blocks to the life on our planet. You need something to compare that to making sure its the same on all aspects of the universe. We don't know that. Life on other planets may not need to survive on air such as oxygen. Maybe "ET's" are made up of something completely different. Until then we won't know for sure.

    I actually think it's exceedingly unlikely for a civilization such as ours to exist at all. So many things had to go our way that I think it's quite likely we are in fact the only civilization in the galaxy... which is a good thing. I don't think any civilization that reaches the point of colonizing a galaxy is going to be kind to potential competitors.

    One correction, most star deaths do not result in supernova (11:05). The dying star has to be in the range of ~8-15 solar masses compared to our sun. If Mr. Gibson was correct, we would witness supernova far more frequently than we do, to wit 1987A. Our sun is relatively typical in mass as suns go and will die as a red giant and eventually equalize into a white dwart. I'm on supernova watch, but I don't expect to see one in my brief lifetime. Thanks.

    So there's between a billion and ten billion or so planets just within our galaxy that might be able to sustain life. Thing is, that life, just like our life on this planet, is trapped on those planets, as faster than light travel is impossible. The closest sun to our solar system, in the Alpha Centauri solar system is over 4 light years away. So, even though it's a foregone conclusion that life exists elsewhere we will never see alien life.
    Unless someone somewhere invents warp drive...

    There’s one general rule that always holds true with human discovery:
    The more we discover, the smaller, and less significant we are.
    For example, the Sun surprisingly did not revolve around the Earth, and if you go back far enough in time, all life forms are related by a common ancestor.
    With that being said, here are some of the next big discoveries I believe will turn out to be true:
    1. Life on other planets (it happened here, and there’s nothing special about Earth or its location).
    2. Time is not special (our perception of ‘now’ is not significant, but we experience it as though it is).
    3. Everything repeats infinitely, either through alternate infinite universes, or within our single, possibly infinite universe. (This follows the same idea for life, which is that since it happened once (a universe), there’s no reason it couldn’t happen again, an infinite amount of times more).
    These don’t have to be depressing possibilities though. For example, you‘ll see your dead mom again someday (or someone else that you love), and you’re still having the best day of your life somewhere else in time right now, and forever.

    I would like to talk to you about one of my experiences with "extraterrestrial life" couple of days ago I was laying on my bed and I got this tension in my front-head and it felt like a wheel spinning I saw all sort of colors coming out of it, it was beautiful but what happens next its what is interesting, all the sudden there were to beings next to my side of the bed , one was a gray and the other one was a mantis, this two were transparent and I was told they were transparent so I would not get scare for their appearance. I would like to tell you that this is happening worldwide to so many people, if you learn to quite your mind, to meditate you will learn that the extraterrestrials are here right now but they can't interfere with the development of a civilization so that's why they can't land on the white house, they can come to you if you ask for! Now you have to learn trough meditation that we are multidimensional beings and there are multiple dimensions and each dimension is full of conscious intelligent beings, the reason I'm telling you this is because we are not going to make contact using mathematics or physics, you or we make contact with Ets by using our spirit , when you go inside of you and find who you truly are your essence you can ask them to come to you and they will come or you can go there to were they are or you can ask them to let you see their ships and they will as long as there is a good intention, I hope you can meditate and start making contact with the extraterrestrials or their spaceships because they are here but not in the physical plane although they can pass from one dimension to another that is really how they travel in space.

    Well done, Brad. And I appreciate you coming in to further comment on your talk.
    My own thoughts on this subject also involve the consideration for the galactic and cosmic dangers the physical dynamic of the universe imposes on the creation and continuance of life. However, I am constantly bothered by the probability factor. It is that because we exist, we must consider the likelihood that other life also exists. This is especially so when you think of the incredible, almost infinite, opportunities the vast universe offers for life to erupt and to thrive. That said, I also consider the less likely possibility of one original life form to ultimately engage in communication with another because of those same physical properties- that is the vastness and remoteness of places life could come to exist within. So, it is practically a moot point. Why consider other life forms if they are so unlikely to both come into existence AND to end up in communication with each other?
    However, when you think of the potential for spontaneous creation of life as we know it on this little rocky planet, it would seem almost absurd to think of life having no chance to do the same elsewhere given the same physical boundaries. Obviously, chance has a huge impact on such ane vent. But, so did out life opportunity, exposed to those same rules of chance. And, I also think of the many times life has had tremendous setbacks on this planet, with comet impacts, Super Novi and frequent solar upheaval blasting vast portions of the surface of this planet with deadly radiation. For some reason, life, once established, always comes through such disaster only to thrive in fantastic ways.
    Of course, given such rare opportunities for life to "Pop" into existence, and to survive the many chances encounters with eradication, the incredible chances for life forms to advance to intelligent life seems as inconceivable as the opportunity for it to even come into existence. One quadrillion chances times one quadrillion chances? We might as well say the odds against intelligent life are all but "infinite" when thought of in practical terms.
    So, to consider the very rare possibility that there is life, we have to think of the equally rare chance that it could evolve intelligence and think of the life forms as existing in some sort of equal advancement stage so that communication would be possible, and add to that the unbelievably rare chance that it could exist simultaneously in a proximity for that communication to even happen in a parr time frame. What is the point of finding intelligent life on a rock 20 thousand light years distant? I would say none at all.
    Essentially, it comes to this: What chance life has to not be unique as it is found here is not the question. What is the difference if other life forms of an intelligent nature exist simultaneously if the chances of the two ever coming into contact are so remote? They might as well be considered alone and particularly unique to themselves. Thus, I think of us as practically alone in the universe and as such, we should always work toward making sure we do not extinguish ourselves (or get extinguished by some odd chance galactic "dangerous thing" as you so well pointed out)- we are so much more precious when we think that way than considering the excessively remote possibility of encountering another intelligent life form that could either destroy us, enslave us, consume us like chickens or provide us with some enlightenment we do not think we possess.
    I enjoyed your talk very much.

It bafles me how life becomes more complex and is able to even avoid getting anhilñiated, I know it's evolution, but the very fact that life evolves is amazing in a unverse of physical laws and matter, an amoeba evolved into a thing that could realize that it evolved from an amoeba, self perpetuating, maybe there is some giant glowing blob out there called life and it is its own thing just as light or gravity, you can say gravity holds us down but you can also say that life defies gravity. If life is just the result of a one in a billion to the power of a billion reaction, then we are living proof that anything is possible in this infinite space and time.

    True, math suggests that alien life can exist, but he raises a valid point. If life is wiped out every few million years, do to rogue comets and gravitational anomalies, and it takes a few million more years to re evolve life from the ruins, and it varies who gets wiped out and when, the chances of finding life gets extremely remote.

    A romantic thought is to believe we’re the only intelligence life out there, not the other way around.
    Light speed limits our intelligence signals search to our own backyard in our galaxy.
    We can’t ignore how vast our galaxy is beyond our own lightyears limit sample, nor the fact that our own galaxy is just an insignificant part of the whole universe.
    Using our own biology to assume what the recipe for life is, it’s also not a wise approach.

    I am also a romantic and I want to believe aliens exist. They are just too far away to ever meet them. Or are they? I dare to bet that we will have aliens among us in a 1000 years from now. And those aliens are sprung from us. As soon as we can colonize other planets, astroids, moons and/or have generation ships/space-stations, that offspring will be a new species. And if they can cross-breathe from those places it will leap into something new again. Every generation from those off-earth locations will be different and adapt. Very exiting times. I wonder what I will still get to see in my life-time...

Earth is balanced perfectly from the sun with a moon correctly sized to eclipse. C'mon my fellow morons; ET put all that in place. They know everything about us. They do return for real this century.

    no such thing as aliens, because they would have AI and would have no use for us they could easily eliminate us without the destruction of the earth

    What Brad did not address is the fact that if we are still here in a million years when a cataclysmic event is due, we will without doubt have the technology to avoid it. In a hundred years we will be travelling to the stars. In a thousand years we will be living on many different planets in our galaxy. Intelligent Aliens exist, of that I’m sure and it is only our arrogance that makes us ask ‘well where are they?’ Earth is that small island off the coast of India where that unfortunate guy tried to introduce religion a few months ago and got killed. We look up and wonder just as those islanders do. We don’t land a plane on the island and say ‘Hi, welcome to the modern world’. Aliens don’t land on Earth as they know it will have a detrimental effect on our natural evolution. We are extremely primitive but we seem to have trouble acknowledging this. We still burn the remains of dead animals and plants as our primary source of power. We haven’t even managed to visit another planet yet and we think that we are qualified to state that it is very unlikely that intelligent life’s exists elsewhere in the Universe. If you want undeniable proof that aliens have visited Earth, look up JAL flight 1628 in 1986. Offer just one possible explanation of that event that does not involve aliens. Just one.

    If we are alone, I take that as evidence that God exists.
    If we are not alone, the industry of religion will be rocked and will have to evolve.

    Truly intelligent life would view us for what we are: marginally evolved apes. The only reason they would "visit" us would be because we have something they want. And they would take it and we could do nothing to stop them.

    If you consider the *only available* data, then 100% of all planets with liquid water have LIFE. We have found 1 planet with water (Earth) and it has life. We have not discovered another with liquid water. So yep, batting 1000.

    They are here and they are not from "space" > Questions? Explore psychadelics, lucid dreaming answers will come. Reality is way weirder and way more intimately connected to our own experience, than commonly assumed.

    I think it very admirable to get in front of a large audience and try to explain a position that is clearly not a mainstream idea.
    Take the criticism as a good thing. It would have been a much easier road to travel to talk about the possibility for life rather than the impracticality of life; moreover, as you explain in your speech about the twenty-four other speakers before you talking about the possibility for life in the universe. The only suggestion I have for you is maybe tweak the title of your speech or your thesis as to “The Universe is out to get you” or “Extinction Level Events” and maybe get rid of the parts about the impracticality for life. You seem to be very knowledgeable about the extinction level events, and seeing some more data on these large scale disasters would be fascinating.
