Maybe one day galaxies will be currency. I mean, money is just a representation of value, and what will have value in an era of intergalactic civilisation? Basically galaxies, everything else will be worthless. And there are billions of them.

Been arguing for this for a while it after all solves the radiation problem and much of the resource issues after all increasing complexity means increased problems so I suspect Dyson colonies for the sake of habitation might not turn out all that practical despite the space benefits because of how easy it would be for the whole thing to fall apart, so long as we keep avoiding performing the necessary infrastructure cost maintenance. :P In that sense planet ships are way more stable compared to the effort needed to maintain it as gravity holds them together that is an allure that will probably never change because nature is lazy. :D

It is certainly possible with the right technology to alter a human brain's perception of time, but without doing that a human brain is still a human brain, no matter how long it can live for. It has its hard-wired functions, its limitations, and perception of time is one of them. While that can fluctuate somewhat (the morning always seems to pass slower than the evening because relatively there is less time in the day, which is one segment of uninterrupted consciousness, to compare it to), it will still be restricted to what the brain can (and indeed MUST) calculate and make the conscious mind aware of.

[@dragoonsunite]

I wonder if any economists watch this channel? I really enjoy your content, and I love how many of the ideas you talk about are actually within the realm of current technological plausibility. The issue I usually have is that when I think about the build up of economies of scale necessary to complete these endeavors, even though the technology isn't prohibitive, I realize the economic rapacity to generate the levels of economy of scale needed is not present, at least for now. Considering so many of the ideas discussed occur on cosmological timelines though, I suppose with those periods of time in mind, the economies of scale are more than adequate to say we're literally almost certainly already on our way, even to creating a Dyson swarm just by extrapolating the length of time it takes to complete such an endeavor and comparing it to the frequency of satellite launches and space based activities we participate in today... I just frequently wonder if many of the people watching this channel are aware of the inherent economic barriers that are in place, in spite of the lack of technological barriers?

[@isaacarthurSFIA]

It inevitably would depend a lot on what the technology was, we can, for instance, plow down a mountain and dump it in the ocean to create two nice new large chunks of living area, it's not really a viable approach though as there are very few high-value land area right by a mountain, and you'd need real estate prices rarely found outside downtown metropolises for that to be attractive right now. However, if you've got a robot that can do it, or better a robot that can make robots that can do it, the dynamic changes entirely. Same reasoning, if I had a building material that basically did not erode or corrode on meaningful timelines, and had a good compressive strength, it suddenly becomes more viable to build up, expensive to make but once done, cheap to maintain. Cheap steel makes railroad tracks, skyscrapers, and reinforced concrete highways viable where the notion would have been previously absurd. Flipside though, economically even if you can do X you still might not do it if Y is better, a hammer made of bronze costing $50 would never sell nowadays, when you can get a good steel one for cheaper, but if you haven't got steel you'll sell plenty of $50 bronze hammers. In this case we're arguing that you might have to go much larger with ships not because you want to, but because it may not be viable to use smaller ones for longer distances and/or the effort involved, huge as it seems, might be small enough compared to the value of the goal that you'd go huge just because you felt it improved your odds, as these journeys are so long that it's not really practical to wait to see if the more frugal option worked.

Arthur's imagination can not be contained by a puny little galaxy.

[@mauricioabyara4171]

The only purpose that a civilization would have to leave a great galaxy equal to ours and make an intergalactic journey would be to go to a rich cluster of galaxies in order to settle in it permanently, an intergalactic trip would not have a final objective of going to any place of the galaxy. Universe as going to another nearby galaxy for the purpose of establishing themselves, but would have a very ambitious objective to justify such a venture for example migrate to a cluster of galaxies that are the largest structures of the Universe united by gravity concentrating from a few tens to thousands of times more matter than all our local group gathered in the case resources for their future. We have some really gigantic near destinations. Norma Cluster also known as the local galaxy attractor located in the area of ​​the prevention plan of our vision with mass estimated between 900 trillion to 1 quadrillion of suns being the second most massive cluster of galaxies in our cosmic neighborhood after the Coma Cluster. Perseus Cluster a cluster of 660 trillion solar masses that it has consists of over 1000 galaxies. Cluster Coma the most massive galaxy up to 330 million light-years away has a mass of 1.3 quadrillion suns and concentrates thousands of galaxies and a gigantic reservoir of gas that shines on the x-ray and infrared. And the closest Virgo Cluster among the 4 clusters of more massive galaxies close to the local group it has 600 trillion solar masses and filaments of galaxies that still continue to feed its growth until 2000 galaxies span the Virgo cluster while in the distant future another 1000 at least they fell in the concentration of Virgo thanks to its enormous mass. As far as the coma cluster mentioned above at 330 million light-years there are other clusters of smaller galaxies than the cited four that such a civilization could also choose to migrate. Any of these clusters cited up to 330 million light-years could be achieved with direct nuclear fusion propulsion or INTERSTELLAR CANDLES. Direct nuclear fusion propulsion capable of reaching a speed of up to 9% of light would put anything up to 1.25 billion light years attainable. While propulsion by Interstellar Sails could accelerate more but surely up to 30% of the speed of light with very strong materials we can have putting a few billions of light years more than achievable fusion. If intelligent civilizations are very rare things to emerge in the Universe in general because of the biological issue then it would be highly accepted for a civilization to migrate to a rich cluster of galaxies and ultimately have access to vast resources if intelligent civilizations are not so rare for scales Let's say 1 civilization for every 60,000 stars so it would be quite acceptable if they continued in their local groups or in their isolated galaxies and that would include our civilization also in the distant future. In Star Wars fiction the Galaxy that was the Star Wars fiction galaxy hosted 1 intelligent civilization for every 20,000 stars, but real life is not Star Wars and we do not know for sure what the average star for each civilization is in our galaxy at least can range from at least a dozen to over 1 million. The direct fusion propulsion I mentioned above is that of deuterium + helium-3 possible to make in very advanced systems in the future. Interstellar candles would also be very interesting. Within 1 billion light years away there are many clusters of galaxies currently attainable in the case those listed by Abell in the Abell catalog. In addition to 2 gravitational attractors at this distance the Shapley Concentration located at 650 million light years where it is currently known that 11-12 of its 25 clusters of central galaxies are in the process of gravitational collapse to form a cluster in the future with a mass of 5 quadrillion suns, and a second concentration at exactly 1 billion light years away known as Corona Borealis Supercluster where it is now known that 6 rich and massive clusters of galaxies are in the process of gravitational collapse to form a cluster in the future of the same order of mass than Shapley's collapse. The Shapley concentration is centered on the famous very massive ABELL 3558 cluster which has a mass of 700 trillion suns according to studies. The concentration of Corona Borealis is centered on Abell 2065 a gigantic cluster of galaxies that has mass of 1.5 quadrillion of suns. Here is the list of all clusters of galaxies listed by Abell up to 1 billion light-years away from us. There are actually many and many others who are not on this list because they are not part of the Abell catalog up to this distance, some of them discovered well after the Abell catalog, but most of them are here on this list. www.atlasoftheuniverse.com/supercls.html There is news that was made last year about civilizations migrating to cluster of galaxies, in order to establish themselves in places where there is more matter possible reunion by gravity, thinking about the expansion of the Universe.

[@mauricioabyara4171]

Achieving any of these clusters would require a lot of resources no matter if the propulsion used was by Interstellar Sails or by direct fusion. But if they are little inhabited by intelligent civilizations then the reward would also be enormous, thus also making the endeavor attractive to this civilization, if they are already populated by civilizations that arose in the galaxies that make them then it would not be appreciable the migration leaving us in our case with the local group to explore in the distant future and colonize. It is worth remembering here that our own Solar System has enough resources to keep quadrillion of inhabitants, and if we still have viable nuclear fusion even after our Sun and our white dwarf has also cooled, we could still live in the Solar System for up to 1 quadrillion of years thanks to the vast deuterium and helium-3 fuel in the gaseous planets of the Solar System that would be mined very slowly to supply our habitable spaces with nuclear fusion reactors in that distant future.

I'm too lazy right now to calculate the total energy in that impact, but I assume it'd be comparable to a supernova or hyper nova. You'd also have a very large amount of extremely hot, extremely fast plasma expanding outwards in all directions.

Thank you for your work, Mr. Isaac Arthur ! I discovered your channel a few weeks ago and find it amazing, I was looking for this kind of high-quality information since a long time ago. One thing I have problems with, is the way-too-fast pace at which the information is delivered in the videos via speech and subtitles. And no, I am not a slow-minded person :) Most of the time I need to throttle the video speed to 0.75 to catch all the subtitles and make sense of all the information. The big issue is, Chromecast and some other KZbin clients do not allow speed throttling. You may want to consider optimizing the subtitle and speech pace for your videos, in order to match the pace of regular TV shows. Otherwise, the information presented is really very interesting and informative, keep up the good work !

And isaac works in politics which is very hot subject in America right now with the added interest what will it be like in the future Isaac has a wide knowledge of and views on political systems in sci-fi novels and other interesting topics I think if someone put isaacs forward after 10 minutes of research Joe would say get him on! I'll be honest I'd no idea how much of an intresting chap he was till I saw his lives.

[@benthomason3307]

A dyson swarm configured to function as a shkadov thruster is basically the same thing. except instead of crudely stapling a bunch of planets together around a fake star, you disassemble the planets and use them as raw materials to build orbiting space stations around a real star, except you only put the stations on one side of the star to function as a solar sail, which pulls the star along with it due to gravity.

Heck of a weapon. What kind of defense could do any good against a planet inbound at .1c?

Throw another planet at it, or get out of the way.

[@Mic_Glow]

Throw a moon at it, move your dyson sphere, change it's course using your own laser highway system, send self-replicating robots that would take over and disassemble it.. idk. Many science-fantasy options.

[@jamesmeritt6800]

Let’s see: if you throw a moon or planet at it, instead on one really big thing coming at you at 67 million mph you have a billion things 500 miles or so in diameter each piece doing 6 million mph. Not much better. Move out of the way? At what acceleration? The incoming really shouldn’t care if the object is shredded, but the target is populated and probably has oceans. Isaac describes some of the tidal effects. Push it aside? How much advance warning do you have? Remember it has a lot of mass and some terrific momentum. If you push it too hard with lasers, you just changed it either to molten metal or a massive cloud, neither would be a great improvement. And a cloud might not be as susceptible to laser steering. And ecosphere (like on the target) is a father sensitive thing. Generally speaking, there are a lot of ways to make things worse and not very many ways to make things better. Maybe a higher k level could do the intercept...

[@Mic_Glow]

@@jamesmeritt6800 Collisions at those speeds are more like explosions, if it happens far away your home system is gonna be fine. As for pushing or damaging the thing- a little push off-center far away will cause it to miss. If the target is a planet with oceans and tidal effects are a real problem for it's inhabitants it probably means the civilization isn't too advanced and is screwed no matter what the enemy does to them.

[@jamesmeritt6800]

Mic_Glow,yup, being someplace else is the best protection against explosions I know of. But if the original was aimed at the target, a LOT of pieces will. Instead of a planet-destroying crash you may only have a few billion explosions, each significant larger than what has been known as the “dinosaur killer”. Instead of sudden death it is death spread out over a couple of weeks. Think relative momentum between the incoming FAST world-shell the the momentum of the interceptor. Now think of the expansion after the incoming interceptor. The original target will (probably) still be in the cone of pieces. The target world might not be destroyed, but life on the surface of it would still do ended.

Very Thic Ship Flying At Incredible High Speed

[@NathanNahrung]

Commenting @ 4:30; The moon doesn't cause tides because of the amount of gravity it exerts on Earth, it causes tides because of the difference in gravity it exerts on one side compared to the other (it pulls greater than average near side, and less then average far side, causing a stretching effect). Because it's relatively close to Earth proportionally to its width this effect is greater then the similar effect caused by the sun despite the suns gravity being greater. Note this doesn't cause water to flow to one side of Earth, but two sides. Also, this is more from water flowing laterally and gathering together and at coastlines faster then it can drain, or draining a local area faster then it can refill. My point is this means its hard to compare this to a linear push which might cause a much greater effect even at lower accelerations. Issac may yet mention this, but for this reason repurposing the moon as a gravity tractor might be better, because the worse effects would be isolated to the moon and the acceleration on Earth would be very natural with the main change being the changes to the Luna months phase.

[@chrisgaming9567]

26:00 YES! *YES!!* There seem to be a steady supply of videos and articles floating around the internet claiming that the expansion of the universe means it'll only ever be possible to colonize the Local Group, and, being a longtime viewer of this channel aware of the possibility of moving galaxies with giant Shkadov thrusters, etc., that always seemed like an excessively, even pessimistically, conservative estimate. After all, isn't the only real hard limit (in known physics) to our colonization the Hubble length? That's a lot bigger than the Local Group!

Actually a video on that would be nice too, as long as I'm submitting requests: How best to transition to a "Kardashev 5" (or whatever level controls the "whole" universe) in regard to occupying and capturing as many galaxies as possible and arranging them so as not to drift apart due to universal expansion or form a giant black hole from being too close together?
