One of my favourite personal story ideas I keep meaning to write about is a type of medical nanite that posses a gestalt sentient mind. They only live in the human body and are symbiotic with "their" human. Their focus however is on the macro scale, so they don't care much about what their human does in their day to day life but more on how it effects their shared body which is their home.

Asimov's Science Fiction magazine, April 2001, "Cockroaches" by Joseph Manizone had several neighboring aliens living in Virtual Reality on their homeworlds, making "bubble universes" with their VR that connected to other alien worlds in VR space only via hyperspace. Travel in real-space was unheard of. Until they found a new planet, Earth, whose inhabitants were making progress with space probes instead of VR.

The Matrioska civilization discussed towards the end is such a fascinating concept to me. The way the different shells offer different experiences of time and different levels of social connectivity is mind-bending to think about. I mean, imagine how much the societies in each ring could evolve and diverge from one another, some changing thousands of times faster than others. Obviously this would be dampened somewhat by the immortality of individuals, as I assume that would decrease the general population’s propensity for change, but still!

Good discussion of the tradeoffs of large Dyson spheres - large size for cooling, small size for interconnectedness. (Or Dyson swarms, but let's not get caught up in that. Dyson called them spheres) I've often thought that we might do better by using a large sphere as a huge heat rejector and conveying the refrigerant to a smaller inner sphere where the computation is done. Heat transfer by conduction or convection is generally more efficient than radiative heat transfer. One downside would be that it would take many years for the refrigerant mass to make a complete orbit so you're not getting as much use out of it as you could.

I think keeping it radiative would be best. Innermost shell/swarm (lets just call it shwarm) collects shorter, high energy photons (UV?), extracts some energy, rejects rest as a lower energy visible photons outward to next shwarm. That shwarm does similar, now radiating out to the next shwarm in the infrared. We do already have photocells that can collect infrared, so make a shwarm for that wavelength. Possibly you could keep doing this all the way to just above the 2mm cosmic microwave background.

Instead of focusing on Dyson spheres collecting a zillion times the energy we can, they start by doing a zillion times more work out of every watt of power than we do now. A Qualitative Kardashev scale instead of a Quantitative scale. Elements of miniaturization fits perfectly into such a scheme.

And most importantly, a vertical farm is more easily automated, and more easily serviced by technicians within the city.

Given just blind luck and happenstance to provide an opportunity for life and an observable universe that seems around 14 billion light years in any direction it would seem to me that we must be among the very earliest to develop possibly even the first truly technological civilization. Give me a moment for this, even starting with say hydrogen and discounting all subatomic activity as factors for simplicity, consider the number of fusions required to produce enough materials to form a human ( I will not even touch the numbers required to produce such an elaborate electromagnetic machine from biological parts) even given a trillion stars per galaxy and a trillion galaxies in the known universe so we have greater chances of success and start with that as our proxy universe. The deck is stacked in favor of life forming as we have unlimited time to achieve it. What we supposedly know of the universe relies on "inflation" to grant us the space to perform our task. What if it never happened and what we see as the inflationary period was merely due to proximity of mass and time dilation caused by such mass. In other words it just looks like inflation due to our current temporal perspective. What I am driving at is simply are we a really lucky fast solution or is the universe far older than we think.

Increase cognitive capacity just a bit, plus grant the ability of minds to "upload," and those alters/characters could genuinely wander off to become their own people.

Ship 3 just sends a people printer/downloader. Once they land they begin printing out souls that were beamed 20,000 years ago from the launch civ. So they are potentially 20,000 years behind ship 1. But if the beaming civ is able to advance technologically at twice the rate of ship 1, they will be even.

I would imagine any civilization, even digital ones, would find value in having offspring simply from the standpoint of strength through alternative points of view. Any civilization not doing this necessarily falls under the Fermi paradox and explains why we never hear anything about them.

That assumes they value alternative points of view. It's also possible that a hyper-conservative civilization could define "strength" in terms of preserving continuity of Tradition, and (if equipped with digital immortality) might reject procreation precisely because the young might get "crazy newfangled ideas" and become troublemakers.

I'm a big fan of your channel, Isaac. Particularly the way you present the logical reasoning for your conclusions (I did physics with Open University). I don't always agree with the conclusions, but the point is this site makes me think about them. For example, not convinced that the human brain can be so easily put onto computer: it's been a few years since I read Roger Penrose the emperor's new mind, but the basic argument makes sense. Evolution will find the least inefficient solution. That solution could well be that our brain's can use subtleties in quantum physics, like entanglement or many worlds, that we are only just figuring out. In that case simply replicating the neural connectome will not capture the subtleties. Also, there does appear to be growing (subjective) evidence that dreams are more than the standard model of neuroscience would have us believe, and that near end of life patients really do appear to connect to "the other side" before death - see publications by Peter Fenwick. I make a point of stating that the evidence is subjective and not objective, but it is statistically significant. To be clear I am not religious, but declare myself as pantheist (regarding the universe as inseparable from spiritual aspects). No doubt I will post more thoughts on other SFIA subjects as time allows...

We are already creating the civilization you describe Arthur, with the "Metaverse." I think we will find that our human (and AI) creations will be far more interesting and exciting than the actual universe we were born into (assuming we aren't already in one).

the intro to this video is basically how I view most of your channel: what happens when we solve all possible problems to making monuments in space.

One solution to the Fermi Paradox could be that there are vast differences from one galaxy to the next, in terms of the amount of habitable planets that also have strong magnetic fields, or some other factor that permits digital devices to exist free from solar wind damage. And perhaps the Milky Way is middling, or even deficient, in this regard. Perhaps there is a galaxy nearby, maybe even in our Local Group, that is much more digital friendly? Or it could be even simpler. Perhaps, once a galaxy exceeds a certain metallicity, you will find that it is teeming with life. Or perhaps there are factors that we aren't even considering. But if this life friendly galaxy is not the Milky Way, we probably won't find it for many thousands of years.

The Landauer Limit and Planck Length are theoretical limits and the practical reachable limits are orders of magnitude higher.

Here's the thing that never seems to get taken into account with the Fermi Paradox. Humans - Homo Sapiens, to be precise, emerged 300K years ago, but due to evolving during a period of glaciation on the planet, farming was not started until less than 12K years ago. Farming is at the very heart of civilisation because without farming you don't settle down. An alien civilisation that evolved on a planet without an ice age, or during one if its warmer periods could be conceivably 300K years more advanced than us. They're probably advanced past radio so any radio signals they leaked likely reached us when we were still hunter gatherers. It's hardly surprising we hear nothing now.

Well we don't just rely on radio communication as our only way of detecting another civilization. We also look at heat. If a star is giving off more heat than the light it gives off suggests, that is an indication that the star may have something around it collecting that light for power, but as excess heat must still be radiated away this shows possible advanced technology. Not to mention that even with a few hundred thousand years head start on us, their signals depending on our relative proximity to them could just now be arriving. An example is if the Milky Way is 200,000 light years across as some now believe and the other civilization started up 150,000 years ago on the far side of the galaxy from us we might have already had their signals pass, they are just arriving, or they have not gotten here yet. As all this depends on when they started using radio and how strong. While they probably would use radio as it is one of the low hanging fruits on the Electromagnetic Spectrum, there is no way to predict if our advancement to it was fast, slow, or average. Nor since we have only sent a few probes out and have no need for powerful communications across stars, just when such a system would be in wide, powerful use. Or for that matter if we ourselves would even use radio to communicate with other stars we ourselves may colonize. This also works with any technology we have developed. It could be we developed farming rather quickly, took forever, or are average as compared to other possible civilizations. With a sample size of one we really can't say how likely many things are. My personal beef with the Fermi Paradox is it's premise that there should be other civilizations out there. The Fermi Paradox as I understand it is that due to the age of the universe there should be other civilizations out there. This is however not exactly true, but instead how we perceive time. We look at the universe as billions of years old. Because that is ancient beyond measure compared to us. Even by the most radical theories I have heard the human race is still less than half a million years old. So we look to the 13 billion approximate years old and think that is ancient. In reality the universe is relatively young. Estimates range of star formation continuing from 100 billion to a trillion more years. And some of the smaller stars lasting trillions and some estimate quadrillions of years. To me this puts the universe still in it's toddler years at best. And based on that I think we are the first or one of the first. If any others do exist we simply haven't had enough time to see them yet.

This seems to contradict itself. I tend to agree more with your second paragraph than your first. Bare in mind that the universe didn't start out day one being able to have life. It took quite some time for even stars to form. Then more time for stars to create the elements in abundance. Then more time for those elements to coalesce into planets. And more time for life to start. The we begin the long climb up that ladder. Which from our one and only example took billions of years. And as that is the only thing we have to go by we must assume that it is average that it takes a long time and has many points along the way in which life can be snuffed out and the process must begin all over again. All of this points to us being one of, if not the, first in the universe.

Has your channel touched on the topic of alternate or parallel dimensions? The existence of these, and the ability to tap them, might explain the Fermi Paradox very neatly. Once a society reaches the level of technology necessary to interact with this alternate dimension or dimensions, they do so and we simply cannot detect them at all with our current tech.

Can you please do a video on parapsychology referencing Dmitry vereshchagin (verishchagin)

from this episode, I propose the grow-slow solution: intelegent civilizations odn't expand to the stars until they use up all the resources in ther home star, and none have yet. this assumes that the assumption in the paradox of an ancient universe falls apart in the math. let's assume that population growth and resources used per person growth are small enough to not outgrow their home star yet. let's also assume that waste energy can be reused, maybe not infinitly but enough to allow a star to dissapear and leave no obvious IR radiation tell tale therefore 14 billion years isn't enough to consume a whole star system if you are agressive about using resources wisely, and since proximity to others matters if there's no FTL communication, no intelegent civilization has reason to colonize the galaxy quite yet. they don't have beacons and havn't intentionally tried to contact us yet. we can't see them because they're all hidden. because you can hide and they won't need resources for another several billion years (or way more) they all might be hiding from each other. this requires science we don't have yet and there are exclusitivity issues possibly at play but it's pretty plausable of an explanation TL;DR we see no aliens becvause they use/store all their star's energy and waste heat, and they havn't used enough of it up for it to be worth it yet to colonize another star. 14 billion years isn't long enough to start seeing beyond K2 civs

Just wanted to comment an idea.

Going to cover the DARPA "warp bubble"?

Disconcerting thought - if it turned out to be the case that we were in a VR, I wonder what the likelihood is that we are in a Matrioshka brain already. The architecture of that doesn't quite remind me of Leonard Susskind's holographic findings in all respects but it's got a similar flavor in terms of 2-D spheres within spheres. Clearly just a random thought but one I'm definitely going to file away for later.

What if we make a simulation that procedurally generate a universe ahead of our exploration to the exact laws what the actual universe have except we can implement ways of traversing this distance. In that sense we can achive space exploration as it would be in the real thing with less resources as we only generate the explored areas in meaningfull detail and the distance this algorithm starts to produce significant deviation from the real thing might be so far out in the digital realm that not even our hacks on it would be enough to reach it in a life time (including a digital life time, counting a desire to die into it). If nothing else this would be a grteat alternative to compensate those generational ship's generations that die trough the voyage but experience the real thing close to death in such a way so effectivelly they wouldn't feel to be just a means to to the end and wastly reduce stress or other complications related to missing fullfillment.

Just an FYI, in "ad infinitum", the last "i" is a long vowel sound.

The main problem for the digital society, that for them it would be even simpler to travel other solar systems. For them existing in a space ship or on the surface of a planet would be the same, living long enough to see the result of the voyage is expected and so on. And since they need much less resource, they could much easier colonize non ideal solar systems, they only need basic materials and solar energy, probably available in any solar system. Also the much smaller needed space means smaller interstellar spaceships, so once again, simpler and faster travel. The only downside would be losing the access of the original network as the lag grows, but that only an issue if we assume every "individual" in this system is 100% addicted to the network.

++ this was a good one

something that kept coming to mind, is the movie "downsizing". they miniaturized humans in some mysteries way, that was never really looked at. but, it was a main plot point, that they used less of everything, costing that much less, to live day to day. so, if some people have gone smaller, how much easier would it be to send they to colonize, and start production plants, for the "normal" sized humans to come to? sending the tiny scouts, who dont need as much fuel, to bring everything they need, to start making everything that the larger people will need. using that split between, to speed up and make colonizing more planets, solar systems, etc. but then, you also have the speed they live their lives, and the cultural issues between, since both groups are still meat, not machines, yet.
