The Fermi Paradox With Neil deGrasse Tyson - Where Are All The Aliens?

  • Since the birth of philosophy, we've never stopped wondering about the answer to the question: Are we alone?
    Neil deGrasse Tyson tackles the possibility of the prevalence of life in the cosmos by comparing our sole data-point we have, life on Earth. He points to the fact that life on Earth formed as soon as it had a chance after the late heavy bombardment period.
    Neil deGrasse Tyson also extrapolates from the fossil record that Intelligence as we humans have defined it is not necessary for survival, therefore intelligent life in the cosmos might be extremely rare.
    In the summer of 1950 Italian-American physicist Enrico Fermi, while walking to lunch with his fellow physicists was having a casual conversation about recent UFO reports and the possibility of faster-than-light travel. Allegedly Fermi suddenly during lunch said, "But where is everybody?
    This later became known as the Fermi problem or paradox. Which is the apparent contradiction between the lack of evidence for extraterrestrial life and the high estimate probability for their existence.
    So what could possibly explain this semblant paradox?
    Whatever is preventing non-living matter from undergoing "Abiogenesis" in time, to expanding lasting life as measured by the Kardashev scale, in the context of the Fermi paradox, is known as the "Great Filter".
    As NASA has explored our solar system and beyond, it has developed increasingly sophisticated tools to address our endless curiosity for the possibility of life existing elsewhere in the cosmos. Within our solar system, NASA’s missions have searched for signs of both ancient and current life, especially on Mars and soon, Jupiter’s moon Europa. Beyond our solar system, missions, such as Kepler, are revealing thousands of planets orbiting other stars. Fueling our imaginations further with bewilderment, wondering if there are other civilizations out there, perhaps asking the same question. Are we alone?
    A growing number of people believe we've already answered this question due to recent UFO reports over the last few years. However, eye-witness testimony and ambiguous video footage does not qualify as extraordinary evidence to definitively answer this age old question. But to be respectful to the people who believe we've been visited by extraterrestrial crafts, we will dedicate a whole video on the topic.

    I think the answer is that evolution of intelligent self-awareness is highly circumstantial. Prokaryotic life may exist everywhere you find liquid water. But here on Earth, three key random instances caused it to evolve further. First: The Great Oxidation event likely changed the chemical composition of Earths oceans, causing a microbial mass extinction allowing for the evolution of Eukaryotes. Second: The Cryogenian glaciation may have initiated the evolution of multicellularity. And thirdly and most notablly, the asteroid impact which wiped out the dumb Dinosaurs allowing for the proliferation of mammals that ultimately allowed us to evolve. Now consider that this random succession of important occurrences never happened on other goldilocks worlds and you have your explanation of the Fermi paradox. Earth may be an example of a relatively unique and rare phenomenon where the evolutionary dominos fell in just the right order to allow for the emergence of technological intelligence.

      To your last point, we can never know the number of combinations of events that could occur that could cause life to form. For instance, imagine there was a dead planet orbiting a star that passed close to a black hole. The immense gravity changed the orbit of the planet into a more favorable position, and somehow kickstarted tectonic movement of the plates of the planet. This caused geological activity, which when combined with the new orbit warmed the planet enough to allow chemical compounds to form that can support silica*based life (because theoretically Carbon isn't the only elementt that can form the chemicals of a primordial soup.), And now life of an entirely different order exists from some extremely unlikely circumstances, just like ours. Considering how big the universe is and how many combinations of events can take place, it seems more an eventuality than a possibility.
      I would tend to believe that the great filter is the formation of the eukaryotic cell. The circumstances of their existence are to specific and strange that it boggles the mind. According to the most widely held belief, a cell attempted to consume another cell, however the prey cell was not consumed, and instead somehow ended up both producing energy for the predator cell (forming the mitochondria) and interfacing with it's DNA in a way that caused the predator cell to build a copy of the prey cell within itself that fulfilled the same purpose. While the hand waving answer of "we're talking about a billion or more years, it was bound of happen eventually", is applicable, I counter it with the notion that in the several billion years following, it was not observed to happen again, nor anything tantamount to it. That occurrence, I believe, is about as unique as the order of a deck of cards, improbable to where it will never be seen again.

    There are plenty of perfectly reasonable answers to the Fermi Paradox. One is that interstellar travel may just not be possible, or at least tangible. Another is that, given the age of the the universe and even the Milkway, few if any intelligent species have co-existed at an advanced enough level of civilization that they could have ever crossed paths. Or maybe other intelligent life just couldn't be bothered to attempt interstellar travel. Just because we think it's a great idea doesn't mean everybody does. It is also possible that an intelligent species did develop interstellar travel, got close enough to earth to pick up our radio transmissions, and said, "Those people are crazy!

    Maybe this is a strange thing to think about but I love the idea that maybe one day we can make contact with an alien civilization and learn their language and be able to communicate with them and make some alien friends. And maybe they can in turn learn some of our Human languages. Maybe it's because already as it is, I have a huge fascination with learning other languages than my own, and the idea of communication and talking to people in general. I feel like it would be so cool to learn another life form's language. Who knows maybe there's an alien civilization out there that's like us humans here on Earth, where they have different languages and appearances and cultures depending on the region of their planet they were raised. I think it would also be cool to use slang in an alien language. It already can be difficult learning a new language, let alone learning the proper way of speaking it vs the more common slang used by native speakers especially the youth. It does make me a bit sad to know other life forms may be avoiding us if they are out there and know of us, but I don't blame them either. All though we have so many amazing people on our planet, the way our species tends to behave, we can pose a potential threat, and on the chance they've raised beyond that, they probably don't want to start some kind of unnecessary war. So maybe it's for the best we never make contact with other life forms. Our species tends to take anything foreign or unexplainable as a threat, and it would be very likely for us to attack, causing mass destruction and a shit ton of suffering, on our side and their side. I wish this wasn't the case, because imagine all the nice and wonderful people you could meet. You could hear stories from them about what their home planet is like and where they grew up. Maybe learn about the types of plants they have, animals, the weather. Maybe their days and nights are far different from hours. Like for example, maybe a day could be like 48 hours for them on their planet or maybe even a bit longer. I wonder what their homes would look like and if they have forms of education and places like schools to serve the education. Who knows maybe they'll be nothing like us in anyway. And maybe that's what truly keeps them far, far away from us. Because we're so different and unpredictable that they don't even want to risk trusting us. But again, I don't blame them. I would be afraid at first if aliens came into contact with us too, even though it is very cool in retrospect.

    I saw this story of an alien who really wanted to visit earth so he traveled 3.7 billion light years just to get here. And when he finally arrived, he stepped out of his craft, and the earth was basically a dystopia with no life at all. The amount of time it would take to get here is genuinely that staggering that honestly if you think abt it, it’s pretty believable.
    I mean, it takes about 9.5 years to get to Pluto. And we’ve obviously been observing(somehow)planets even farther away so it’s not hard to believe that if there was anyone out there, by the time they get here, no one reading this comment would be alive to see it.
    Which means we’re basically alone. And if there is other life similar to us(not fantasy aliens with super high tech) they would feel the same, alone. Bc it’s seemingly impossible to get that contact before either one of us went extinct.

      with infinite energy you could technically get anywhere in 5 minutes. The acceleration of an object is always proportional to the force applied to it and inversely proportional to its mass. So as long as you have energy you can accelerate infinitely. But there is a catch. No matter how fast you go, as soon as you turn on a light in front of you, it will go 300 000 km/s in front of you... and also go at 300 000km/s for an observer on your native planet. So for you it might take 5 mins, but for your people it will still take billions of years for you to take that trip.
      So your story still makes sens. Not as it takes to much time for the alien to come here, but in how will the state of their own civilization will have changed by the time they come home from their trip.

Well this is NOT correct. The speed of light can be broken not doubled or trippled but the speed of light can be broken by millions of times, the aliens know how to build spaceships that utilize the zero point energy fields and can travel million times faster then speed of light..Also you may think that because all life on earth needs food and oxygen to survive you fail to see that some alien species simply do not have lungs and stomachs so these human limitations do not apply to them.. You also fail to see that if you found your self on Earth a 1000 years in the past and you started explaining to the locals that where you are from we can fly in helicopters and swim under ocean in sub marines and we have TV and magic communication devices called a telephone, good luck explaining all of this to humans that lived on earth in mid eval Europe for example.. The way technological progress advanced in only last 150 years it would not surprise me if 500 years in the future or less we too will build spaceships that can travell million times faster then a speed of light. And if you consider that all this technology we have today the aliens had lets say 20 million years ago, and if we do not destroy ourselves given the technological progress of only last 150 years where are we going to end up 20 million years in the future technologically speaking? By the way human thought travels faster then speed of light.. If you compare the speed of human thought which is instantaneous in all directions ((LIMITLESS)) then speed of light looks like a snail's speed.. Its like comparing apples to bananas.. Compare to the speed of human thought the speed of light might as well be 1 km per week..

Basically, I’m content to know that I don’t know and that perhaps things may be revealed to me at some point, or not at all.

This is currently not feasible but still a good dream to strive for, however if there is intelligent life out there and it is not on one of the moons of Jupiter or on Mars we will never see any true intelligent alien life within at least the next 4-5 Generations and that’s with rapid Technological advancements.

Just because those radio waves become indistinguishable (not undetectable) from CBR after a certain amount of time, does not mean intelligent species, like our own, are not able to extract meaningful information from CBR especially if those intelligent species have the right equipment and know how that can extract such data, and as of now, we have the equipment to extract meaningful data from CBR if we recognize abnormalities. From what we've seen so far, there have been no abnormal CBR readings we can further extrapolate information from.
      Now as for intelligent life being out there who can't contact us, who cares. They, like us, are on a timescale toward extinction and if they do not find a way off of their respective planets before they go extinct, does it really matter (to us) if they ever existed at all? Not to me. I only care about sentient life that we may someday be able to contact. Not in my lifetime of course, but someday. I also care about humans being around long enough to make the technological progress to be able to contact such life.
      And Radio waves move at the speed of light so we've been broadcasting for more than 100 years which means our broadcasts have spread out in all directions going the speed of light. Are there habitable planets 100 light years away from us? Why yes there are, so where are all the aliens? Probably dead due to climate change and climate devastation. But, only time will tell.

Look at viruses, some people don't consider them as living, and I understand why they would think that but they do things to keep them alive. What I am saying is life could just mean things could reproduce in any way, I know this is the most general thing but could you really expect to go to a different planet see creatures exactly like humans, pretty unlikely.

    1) A need for fire and the ability to make and control it, for without fire you cannot manipulate materials.
    2) Be a social creature, not solitary, since no individual can develop technology on their own.
    3) A sufficiently long life span to develop skills and pass them on
    Take the octopus. A good candidate for intelligence. It demonstrates complex thinking and has the dexterity to make tools. However, they live in water so will never need nor make fire. They are solitary, so do not share and pass on knowledge. They live for only a few years so only have time to reproduce and die, no time to tinker.

      But intelligent life is rare. Neil said it himself. Millions of species on earth in the last 4 billion years have developed eyes, and mouths, and ears, and hair, etc.. But in 4 billion years, on a planet thats abundant with life, intelligence has happened only once.Thats proof beyond all doubt that intelligent life is extremely rare and possibly even unique to us.

      @@joshualee7709 just my humble opinion but maybe intelligence has happened, but it has never passed further. Perhaps this is the edge. Any further and its only void. We built things and put them in space but our progress is minuscule compared to the unfathomable expanse of the universe. Just like someone said, " we're just a grain of sand in the sahara desert ". Just my morbid prediction but once the james webb space telescope launched, if it cannot detect something awe-inspiring like an actual civilization in its images then human intelligence will have little to look forward to. After that, there will only be squabbles and quarrels happening in earth. To rephrase life will be cold and bare, just waiting for the inevitable.

      I think that if anything, we MAY be seeing unmanned probes from other civilizations launched hundreds or thousands of years ago. Much like how we send out probes but on a bigger scale.
      That said, I doubt even that.

    Vast, mind boggling cosmic distances between worlds is what keeps us from finding anything. Advanced alien civilizations may have technology to overcome these distances, but they would be so advanced that we could not yet comprehend their technology.

    If the closest extraterestrial civilisation able to radio transmissions is just 300 parsecs away and is transmitting for 2 centuries we need more then a century from NOW till we pick something up...

    • @stevejensen3471
      @stevejensen3471 Před 2 lety +4

      300 parsecs = 978LY. Assuming a transmission lifetime of 200 years, that would correlate to a 400LY radius with the transmission energy decreasing by a factor of 4 as the distance is doubled according to the inverse square law. So you would need at least another 275 years to listen.

    Sometimes, you have to go beyond knowing everything and know nothing to find what you are looking for. There are riddles in your own backyard that are avoided (publicly) that will lead you to your answers. Somethings are stranger than fiction and the ones who continue with the strange will find life beyond what you "know". Be brave.

    The fact that we can't see it, doesn't mean that alien intelligence isn't there. The universe is unbelievably huge and earth is a very very very small grain of sand. I personally believe that we are most definitely not alone.... I'm pretty certain the Aztecs might have asked themselves the same question at some stage in their civilisation.
