The observable universe is a big place that has been around for more than 13 billion years. Up to two trillion galaxies made up of something like 20,000 billion billion stars surround our home galaxy. In the milky way alone scientists assume there are some 40 billion earth like planets in the habitable zone of their stars. When we look at these numbers it is hard to imagine that there is nobody else out there.

  • If you consider the current age of the universe relative to its predicted total lifespan, the universe is still incredibly young. We could very easily be the first civilization to reach our level of technological advancement. Depending on how long it takes, on average (whatever that means if we don't even know if there is a distribution), for a planet's tree of life to produce a space-faring civilization, if there isn't another such species in the galaxy right now, we could potentially expand across the entire Milky Way before another one forms to compete with us. It's really a matter of how rare it is and how long it takes for a species to reach the point of interstellar travel versus how quickly a species can expand once it does so. If we expand quickly enough and utilize all of the galactic resources, we may prevent any other species from doing so by out-competing them. Alternatively, another species with even a slight head start on us could be doing the same right now. It could only be a few hundred years before automatic mining drones arrive in our solar system to wipe us out. Or it may never happen. From this point of view, offensive aggressive expansion may be our best defense as a species.

  • I have a problem with the idea that "since we haven't found evidence, there should be no very advanced civilizations". As you said earlier, we have just started looking, and so far, we can only be sure that there are no such remmants or signs in our solar system, which is only ONE star in a sea of countless trillions of them. If they haven't arrived here yet it doesn't mean that they do not exist, maybe there are better places to look for something, better stars to exploit, or better peoples to conquer. It's as if a single fish in the pacific ocean doesn't believe humans exist just because it has never seen a fishboat. Maybe some strange things we do see are caused by very advanced civilizations but simply rule that out because, well...there's really not way to know from millions of light years away.

  • You should make a civilization building game with this graphics, with real science in it. I would buy that game. So would ten million more people. Do this. By the way, we wil not be an interstellar civilization. Long before we achieve that, we will be able to transfer all humans' consciousness' to a mega\giga\uber computer, and live inside it as immortal personalities in a fantasy world. Each one of us will be able to understand each others' thoughts and experiences, and each one will have a private space where it (maybe by then gender will be meaningless) can create its own personal pocket universe. After that point, we will just find an inexhaustable power source, like a red dwarf, attach our (probably many kms in diameter) giga computer consciousness heaven to it, and live happily ever after. Or at least a few trillion years, then we will have to find another host as parasites. This also explains Fermi paradox neatly. Do a video on this maybe? After you finish the game you promised?

  • So your theory is that if there were any Type 3 or higher civilisations in our home galaxy now (or in the past), then we would be able to clearly see the signs of their presence and know that they were there, because they're too big and powerful to NOT see, right? But because we don't see that stuff, they can't be there and never could have been... But what if they're so powerful, that their actions just look - from our perspective - to be part of how the universe works normally. That the only reason that the universe even looks and acts the way it does is because Type 3+ civilisations have been redesigning it to work in a logical manner that is beneficial to them (and the fact that it's habitable for us is merely a coincidence)? After all... Any sufficiently advanced science is indistinguishable from magic. What if any sufficiently advanced "sufficiently advanced science" is indistinguishable from the natural laws of the universe?

  • I like idea that once a civilization advances far enough, it ceases to expand and turns inward to virtual worlds. Harness enough energy to sustain for civilizations. Then escape into virtual worlds. Where death, etc is no longer a thing. Modify your subjective time so that a second on the outside feels like a million years on the inside. These virtual worlds could be as limitless as your imagination.

  • So first few seconds into this video. War, terror, and violence were the sole responsible factors to human success. Wow Kurzgesag, let me ask you why do human beings spend more time in infancy then any other animal on earth? I will just give you the answer which is culture. Humanity has not evolved because we do not have to our culture evolves for us. So culture allows shared information on helping us to build our own eco systems which gives us the ability to survive any where and go everywhere. We were not the only animals with this ability like look at crocodiles. They create a pond and a stream to that pond to farm fish. This is true with many animals just not to the degree of humans. War yes can inspire culture, to advance in weaponry but it is not the only thing responsible for it. Really the answer to human success is culture. Okay I got out my grrrrr time. Thank You

  • 3:23 I'm skeptical about a multi-galaxy-spanding civilization. Last time I checked the universe was expanding exponentially. The only other galaxy we are ever likely to reach is Andromeda, only because we're moving towards each other. You'd need faster than light travel to reach any other galaxies for how fast they are moving away from us. Which I believe all scientists agree is impossible. So our only hope lies on the slim possibility of controllable wormholes. We would need hundreds of years of study just to get to a point where we can semi-accurately predict the exit, let alone find/create one.

  • *Open question/discussion to anyone who is particularly knowledgeable on this subject* If X civilization (say, humanity for simplicity) were to harvest 33.4% of the energy from 3 planets, each planet having the same total amount of harvestable energy as earth. Would that make humanity a type 1 civilization? Because we are harvesting 1 total earth worth of energy but we are harvesting less than half of the energy of our native planet. If there is a definitive answer then just tell me because I am curious and have no clue how to phrase it to google, and if there isn't a definitive answer then give your opinion, I would love to see a bunch of smart people talk about it.

  • The Kardashev Scale has always pissed me off because it's so incredibly presumptive. Why assume that living things inevitably trend towards civilization? This reflects an outdated and unscientific conception of evolution. And why is the possibility that life is unique to Earth always dismissed out of hand? We cannot even begin to compute how likely it is for life to evolve, as we have insufficient data to work with. Also, look around you. The future is a lot more likely to be a dystopia than a utopia. High-IQ people are pretty much going extinct, being drastically outbred by low-IQ individuals. I do believe humanity has the capacity to colonize other planets, but I think that's a future that only could have been if the 20th century played out differently. Frankly, the only future I can imagine now is a world where every inch of the planet looks like Haiti - covered with trash as far as the eye can see, and dominated by a cosmopolitan billionaire elite which rules over a deracinated, monocultural global serf class. The future of mankind is to be entombed within our own machines, molded to fit a mechanical world, with everything that originally made us human stripped away. Technocracy is by far the most authoritarian ideology as of yet introduced to civilization, just think about it - when in human history has power been this centralized before? Authoritarianism isn't merely some boogeyman from mid-twentieth century regimes, it is very much alive and well in the form of globalist neoliberalism. Wages have stagnated in the west since the 70s. We aren't becoming more advanced, we're being acclimatized to a third world environment. Sure, robotics is developing, but that will only ever be relevant to the rich, with most of us facing a lifetime of paying rent to live in a tiny box and no sense of community to speak of, in fact the Covid lockdowns have basically criminalized community activities. And believe me, they'll never end. Also, if you haven't noticed, most people are depressed. At what rate does it stop being a "chemical imbalance" (blaming the individual) and start being indicative of a societal malaise? I'd say when suicide is one of the leading causes of death for young adults. I hate to put a damper on a fun video, but I just feel like the whole "Look how cool the future will be" message simply doesn't ring true. For most of us, the future will just mean more nihilism and less rights. And no aliens will ever come to save us.
