    If we are talking about generation ships it might be easier to have artificial wombs rather than reproducing naturally.

    I'm thinking of ship designs: you showed a planet ship in another video – instead of a full planet use a small control ship to be the heart of a spherical ship. Each layer added over time, the seed ship separates and begins making more layers again as it gathers and stores materials like fat in the body. The first sphere will be the first colony with all the materials it would need. Space and time would not be complicated as it would be added as needed for any basic technology if no significant advances are made. Using well developed current technologies we could start a seed ship from earth to the moon; from the moon to Mars; from Mars to Asteroid Belt and so on. WAITING for our PERFECTION may not be WISE. Though ALL these IDEAS are SAFE and PLEASING – they might be what keeps us from getting away.

    a very interesting statement from Isaac about tears and oceans… here from the Buddha 2600 years ago :

    Which is more: the flow of tears you’ve shed while roaming and transmigrating for such a very long time—weeping and wailing from being united with the unloved and separated from the loved—or the water in the four oceans?” “As we understand the Buddha’s teaching, the flow of tears we’ve shed while roaming and transmigrating is more than the water in the four oceans.”

    “Good, good, mendicants! It’s good that you understand my teaching like this. The flow of tears you’ve shed while roaming and transmigrating is indeed more than the water in the four oceans. For a long time you’ve undergone the death of a mother … father … brother … sister … son … daughter … loss of relatives … loss of wealth … or loss through illness. From being united with the unloved and separated from the loved, the flow of tears you’ve shed while roaming and transmigrating is indeed more than the water in the four oceans. Why is that? Transmigration has no known beginning. … This is quite enough for you to become disillusioned, dispassionate, and freed regarding all conditions.”

    Isaac, thank you 🙂

    Even as late as the 1840's, people in Ireland who were lucky enough to have an opportunity to immigrate to the US held what was called "An American Wake" which was basically a funeral for the person who was leaving. Because to friends and family who were staying, the immigrant was, for all intense, dead.

    ISAAC, Please could you write a fictional space book combining all your science facts and videos into amazing book one…I love all your videos and think it would be amazing as a movie or book (Im sure John Micheal Godier would not mind helping with it) please consider it!

    Methuselah ships are the ultimate form of social stagnation – a king has his reign and then he dies, it’s inevitable.

    The discussion around the prospect of someone leaving and never seeing their friends and family again reminds me of the old Irish traditional called The American Wake (https://www.encyclopedia.com/international/encyclopedias-almanacs-transcripts-and-maps/american-wakes). It was one last party before the person left for America and was the last time most of the people would ever see them again.

    Isaac, I assume you know about dunbar's number, the general limit of ~150 people that one person can know. I was reminded of it when you talked about how colonies would have a lot in common if they came from the same gardener fleet. At first I found that hard to believe, but then I realized, mind augmentation.

    I am now pretty sure changing that kind of thing will be common once possible.

    Isaac. Have you read any Alistair Reynolds? More specifically the Revelation Space series? Listening to this video has got me wanting to dive back in a reread the main trilogy. I highly recommend it if you haven't. Methusala style travel, Fermi implications and AI/transhumanism escapades. What's not to love?

    Just found your channel a couple days ago via Curious Droid and can't get enough.

    Keep making these videos, please. The animations, the the deep topic development, the duration, your voice; it's just a perfect combination. This is way better than any other sci-fi content on any other platform.

    What if the paradox is like you said they have seen or are afraid of the colony attacking so they do not make colony but limit birth rate to maintain stability of the planet population

    Gotta say, I love the way you integrate the sponsors into the topic so seamlessly. If I look away, it will be a couple sentences before I even notice the advertisement, because it ties in so well.

    Hey im a huge fan, I found your videos a few months ago. you really got me interested in space, science and the future. I'm not a scientist or anything but I have been thinking about how the universe expands faster and faster and why it does that… Could it be that all the mass and matter at the starting point of the big bang got ejected at such a rate or with such force that instead of leaving no mass, it leaves negative mass and there for keeps on speeding up for ever. You know because of negative gravity. Is there any way that this could happen? Or is my brain just playing tricks on me? Keep up the great videos I really enjoy them

    I would recommend that you prepare to scale your videos to 4k resolution (maybe in 2-3 years it will begin to be mainstream, so that you can do it bit by bit).

    Are those rumours about Moon volcanic caves real?

    Apparently there are a lot of long galleries on the Moon created by volcanic lava billions of years ago …. I'm a bit skeptic about it.

    :46 We won't send colony ships. The concept, its pro's and con's, and many thought experiments have already taught us that we should NOT exceed the range of our vehicles top speed. Meaning Don't go anywhere if you can not complete a round trip within short time spans.

    Hey Isaac, ever read The Conspiracy Against The Human Race?

    I recommend it.

    Oh, and btw Transhumanism is a form of religion. You worship technology as your savior and believe it to be your salvation. Sounds a lot like the Christian after life. Living forever, boundless resources, no problems, all things solved.

    I get the idea of where technology can get us. But… and please forgive me if I missed something… just because we can does not mean we should. We set a narrow and likely incorrect definition of life and use it to justify concepts like "harvesting whatever we need" from the universe. Like we feel it is ours. We cannot take care or each other nor stop killing and wars. We totally trashed this place and exterminated species. We set off thousands of nukes inside our ecosystem. Now we feel it necessary to trash space around us. Who do we think we are going anywhere else? Doesn't it seem as though we are putting the cart before the horse?

    It seems it would be impossible to colonise the galaxy without the colonies diverging so much they would become alien to each other.

    I've always felt that for us to become a true space fairing species we will have to master manufacturing in space. Not just some disciplines of manufacturing but virtually all of the processes we have here on Earth will have to be transferred to space. Shipping stuff up from Earth is just too expensive and energy/resource hungry. We have to be able to refine metals from the moon and then turn that material into construction components. We have to be able to manufacture electronics. We have to grow our food in space. We have to be able to do everything and at the same time protect ourselves from not being killed. It seems logical that we culminate in the O'Neal cylinder / Babylon 5 type of structure. This would allow a multi-generational / Methuselah paradigm to operate in the colonization of the Galaxy. There is one fundamental problem with this scenario. Once we got there we wouldn't want to get off the ship. We'd much rather build more ships since we would be so good at it by this time. By the time of arrival we would have become a space born civilization and our robots/fabricators can build any number of habitats without the annoyance of a gravity well.
    Ever been on a cruise? I mean a good one? Did you want to get off at the end of it? Now instead of a week imagine your whole life on the cruise. Are you really going to get off you're nice clean habitat to go live on that dirt pile down there? I don't know about anybody else but I'm staying on the ship.
