Planet Ships

- Опубликовано: 12 сен 2024
- Earth has often been compared to a spaceship, one that's successfully orbited our star and the galaxy many times over billions of years. So what about moving our planet or even converting it or another world into a spaceship? Can we use entire planets to cross the intergalactic void to settle planets in distant galaxies or superclusters? And what sort of engine and drive could move a whole planet?

This channel is insane. Just casually talking about moving planets and even solar systems. What next, using galaxies as shurikens? I LOVE YOU
😂😂😂. I'm guessing you haven't seen "Colonizing the Sun" or "Black Hole Farming" yet. 😂😂😂
Seriously though, this channel is insanely good. I'm already saving money for my first O'Niell Cylinder.
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. We could well see a universal stock exchange where corporations spanning billions of light years are trading in galaxies. What they will be buying and selling is beyond my comprehension.

@@someguy3766 You're not far off, actually. In such a highly advanced, post-scarcity civilization, there will essentially be two types of currency: raw mass and energy. Information might also serve as a form of currency as well.

Total badass
He sure makes it sound easy.
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

Cool quote... Bad TV Show... I mean I guess alright TV show, it's basically justt our reality TV today, but witth future technology, and no solar systtem... Which to be fair, in most earth drama, thte solar system doesn't play a really big part. I think itt could be made 'more' interesting perhaps if you focused less on the 'people' and more on the voyage in installments... IE the episode start... "Generation: 243, Near Rogue Black Hole Pass" and then the next episode "Generation 321, Whatever Cool Thing Happens Then."
This is actually the concept of a science-fiction novel and movie that's popular in China, 流浪地球 or The Wandering Earth. It mainly talks about the sun's instability and how humanity uses engines to propel the earth out of its orbit in order to avoid the sun going supernova. It's quite an interesting read (if you haven't read the books or watched the movies already), so give it a try! Oh, and also happy arthursday!!!

The more we extend out lifespans the shorter these trips will seem. Who's to say in a billion years that a 1000 year journey would be little more than an afternoon walk in comparison.
Exactly. We can also get time dilation traveling at relativistic or ultra relativistic speeds.
@@crazyahhkmed ultra relativistic??
@@supershenron9162 practically at light speed. For example 99.9% of light speed.
I dunno about that, certainly a lot of modifications would have to be made to human brain physiology to make 1000 years seem like nothing. 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.
@@someguy3766 Easy with a sleeper ship. Wake up and find millennia are gone.
There's a French sci-fi book about Earth turned into an insterstellar ship, "Terre en fuite".
We're really just a century into really beginning to understand physics. We just got to the point where we know that we know very little about physics. There are solutions to this that haven't been dreamed of yet. It's like asking a person in the middle ages to conceptualize how to build a cell phone to communicate around the world instantly.
And we have no idea what new technologies, sciences, and surprises await us, it just gets crazier and more incredible from here

Hmmm...Next Episode, Moving the Milky Way, after that, Moving the Local Group...
@@mortimerhasbeengud2834 Moving the Milky Way is just a case of sticking shkadav thrusters around most stars. I think he touched on this in intergalactic colonisation.
Every project needs a budget, and I guess that must wait for other technological milestones.
I’m late to the party.
On that note, it’s kinda funny how we went from whole solar systems as ships with shkadov thrusters and then scaled down to planets.
Even in the future this will be known as:
1. Sticker Shock
2. Budgeting.
Mortimer Hasbeengud damn straight. I’m sure budget cuts are bound to still be a thing.
@@nickwalker4936 Ha! Nick! Everything in the future will have a budget (Like THX1138!) including like, the Omega Point, but the cash flow will be based on computing cycles, rather than, Bitcoin. Hey man, don't look at me like that! "It's in Revelations People!" (pant-pant)
Mortimer Hasbeengud I know. I was thinking that “currency” wouldn’t really be something to exchange but rather a system of measurement for productivity for post scarcity societies.
We scaled DOWN to moving planets! Welcome to SFIA!!
"since the sun is not coming along... this time anyway," i love quotes like this iconic of this channel
Just discovered your channel a few weeks ago and I really like it.
Assuming we do convert Earth into a spaceship, how will we get it out of the hangar bay(i.e. the solar system?)
Assuming our thruster tops out at 10 micro G's, that means we'd have to escape solar orbit by making a SUPER long spiral path as we accelerate along our orbital path. The solar system may not be totally flat but pretty close. Using this method, is there a danger of getting caught in say Jupiter's gravity well?
Aim for it to get a slingshot.
@@roblaquiere8220 Noooooo don't do that! Remember 10 micro G's is our limit here. Doing a slingshot maneuver will blow WAY past that. Maybe just move the planet "up" relative to the solar plane?
@@carloguerrero6583 Didn't think of that one. The truth about moving planets though is that if you can control enough energy to move a planet, you control enough energy to not use a gravity slingshot while doing it.
Moving a planet has more problems then that though... imagine what will happen to the ecosystem should the Earth be moved this way! Better to just move the Sun, and let the planets tag along with it...
@@roblaquiere8220 I forgot something too. We'll be changing the solar system in big ways before moving planets is even considered. I say let future peeps choose how they pack up and leave :p
I'm so far behind!

The people that downvoted this video are the reason we dont have a working movable planet spaceship.
It is not the quantity of the down votes, but the quality, that counts..
So if a 11 to 12 xenophobic technophobe people hit a down vote.
Does that not count as an up votes?
@アテナ2003麻宮 , Some do hate humanity. But most hate the fact that they are not in command! So calling them misanthropes, might be over generalization. Then again, perhaps not..
As for leaving my biological humanity behind, I hope for a more dualistic approach. As being both man and machine sounds fun..

However, I would not recommend someone playing with fission in their backyard..
Imagine some force trying to attack a relativistic planet ship and the space clearing lasers just cutting them to bits before any dramatic battle could even be thought of.
*OR,* better yet, a force knows they have this tech, so they bring an easily melted shell full of lead chunks so that when the lasers auto target the meteors, the just spray a debris field across their path.
What I'm saying is sci fi should adopt this idea in a battle sometime in my lifetime.
What they forget is that planets often have real life force fields called atmospheres.
@@johnrickard8512 and depending on weapons used the magnetic field could cause issue too.
And perhaps the attacking fleet would make extensive use of mirrors to deflect the point defence lasers, while either re-directing them or using their own point deffences to destroy railgun slugs and missiles trying to destroy said mirror.
Which also gives the thought, a micro black hole could be a nasty thing to fire at someone if you got it going fast enough since you can't simply shoot it down, you either have to evade or fore something at it to deflect it, that could be a fun-if-extreame sci-fi weapon that something like a Planet ship would have more than enough energy to power
@@johnrickard8512 Well, we're talking about lead god-rods being put in the way. I doubt measly nitrogen and change can stop that while cruising at relativistic speeds lol
@@EnPriBricks True.
Now I'm wondering what would happen if you smashed together two planets that are traveling at near light speed
many asteroids flying everywhere would happen
@@jgr7487 no, I think the material might get vaporized or something similar to that, perhaps they'd collapse into a black hole? I don't think it would be that boring
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.
I remember a book called "The Jupiter Theft". In that case, the planet moved was a gas giant and they included one of the moons as a radiation shield while they had 5 generation ships hiding in the shadow of the moon. Their method of movement used the gas giant as a fuel tank and created a lot of radiation so a moon was necessary for shielding. I suddenly recalled the book when it was mentioned that you put the planet in orbit of a gas giant and move the giant.
Oh look another amazing concept being covered by SFIA
Never gets old :)
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?
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.

Isaak Arthur Moving an earth like planet with a gas giant does NOT require to move the planet first to the gas giant.

I vaguely remember a series of stories from Galaxy mag that did such stellar engineering. An interstellar ram scoop pilot comes back home millennia later and is uncertain if it is the right system as earth has been shifted out and saturn is missing. Turns out they used fusion candles on Saturn to gravity tug the earth.
B. S. That was the first thing I thought of. Though I read them collected into Niven’s 1975 novel “A World Out of Time”.
also while tidal forces create tidal heating they do so depending on the strength of the tidal forces and the rotational speed of the earth - if we stopped the moon in it's orbit and used angled thrusters to counter the gravity and keep moon at a cosntant distance so that the exhaust does not hit earth (because they are angled slightly) - we could move the earth by gravity tractor without applying any extra heat to it - the earth still spins at the same speed and the tidal forces are the same - well the moon is no longer orbiting so the relative rotational speed would be one rotation per month more - so the tidal heating would be 1/30 more than currently - or about 1 extra Kelvin of overall temperature every 200 million years
the main source of heating would be the potential of engine exhaust hitting the earth which has to be minimized by very directed engines slightly angled around it
with the moon that would allow us to accelerate earth with 1/300000 of one G while the tidal forces experienced at earths surface are actually about 1/9000000 of one G
if we want to build an artificial gravity tractor, as massive as earth producing a bit more tidal force than the sun and moon combined that would mean we could place it about 3.5 times further away (3.5³=42.875 so it would produce about twice as much tidal force as the moon and about 1/3 more than the moon and sun combined on a new or full moon)
and we would get 80/3.5²=6.5 times as much acceleration or about 1/46000 G
that would bring us close to the speed of light in about 46000 years - in that time we would travel 23000 lightyears since we're constantly accelerating so our average speed is about half the end speed - if we slow down again we have traveled 46000 lightyears in 92000 years
since for a constant acceleration from stillstand distance covered is proportional to time squared it would take 1/100 the time to travel 1/10000 the distance or 920 years to travel 4.6 lightyears roughly the distance to the nearest star - or around 1840 years to travel 18.4 lightyears
"What about making a spaceship _out of a planet_ ?" Yup, it's got to be a SFIA video!
"Inter-supercluster colonization..." Dude, you have _got_ to start thinking bigger! [joke]
[later] Contemplating colonizing billions of galaxies at least 10 billion ly away--OK, you started thinking bigger!
Arthur's imagination can not be contained by a puny little galaxy.
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.
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.

What about Real or Artificial Solar System Ships? Like in Andromeda (Sci-fi Tv series) with the Magog Worldship.
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.
I'd been thinking about this topic ever since I saw colonizing jupiter and the intergalactic colonization series.
This confirmed some ideas I had, letting the planet fly through a galaxy and send off seeds. However, It destroyed my idea for a Fusion Candle vessel with alot of habitats around it.
Earth leaving the solar system might happen faster than Brexit...
Sorry I had to.

I see they are bringing their moon along also.
Well you get attached to something like that, a moon I mean.
:)
This one gave me goosebumps! Hope someone is archiving these videos for the seriously long term...
I love the idea that some smug super civilisation in the distant future will proudly proclaim their intention to colonise other superclusters, believing the concept was conceived relatively recently in galactic terms, only to be shown that their pre-galactic, pre-interstellar, even pre-interplanetary ancestors had discussed the concept and considered it ‘easy’.

8:31 "...since the sun is not coming along. This time anyway. We'll discuss moving entire solar systems in the next episode of the series." I almost couldn't tell if this was serious or not but this is such an SFIA sentence so of course it's serious
Downloading to listen to on my way to work. I'm very excited for this one!
If you're mostly listening you can probably save some bandwidth downloading the audio-only version on soundcloud and itunes
@@isaacarthurSFIA Yeah that's true, but I'm already paying for RUclips Premium, might as well make the most of it ;-)
@@MAD-SKILLZ I remember once reading an article about how much each google search costs (money and energywise), so please do your part and download audio-only :)
Wondering earth!
When you think you've heard it all. Planet Ships! I'm baffled :)
You missed the Shkadov thrusters episode. Solar mass ships are 330,000 times as heavy as Earth mass ships.
I'm a huge sci fi nerd but Isaac still manages to blow my mind with the concepts he describes
180!
Food ready and now I'm going to watch this:)
Now I've watched it.
M.o.v. i.n.g planets...
Thank you so much for what you are doing, and how!
Let's found the I.A nation with help of A.I.
Yes.
I just watched a movie on Netflix called The Wandering Earth. It's Chinese but dubbed in English. It was very interesting. I think they must have watched your channel. Some of the physics is a bit iffy and it might be fun to analyze it for accuracy.
Sephiroth: "Yeah, like this guy said."
Cant wait to start yeeting planets around lol - who needs a cruise liner when you can just toss your planet to that nice looking cluster of stars over there
"we are not moving the sun with us...yet, we'll see how to move solar systems later..."
Ok then.
Nice, I thought of this a couple months ago. It makes you wonder if that's already what we've done.....
The issue is if you move a planet you must bring a star with you. I'd rather a giant ship with everything needed and collect resources from asteroids, planets and stars on the voyage to wherever you go. I believe we have been travelling for quite some time.
You don't need a star in the classic sense, sure massive fusion reactors for power would be essential, but all you really need for the earth itself is the normal amount of light and heat, which would be even easier with a shell built around the Earth since it could help hold in the correct amount of heat
Kinda disappointed you didn't mention The Wandering Earth
Here are a few (good) scifi novels starring moving planets:
- Frederik Pohl&Cyril Kornbluth: "Wolfbane" (where the Earth itself is sent whizzing through the universe, with the Moon as a temporary Sun)
- Fritz Leiber's classic "the Wanderer" (admittedly, the aliens use hyperspace-tech to fly their planet)
- Donald Moffitt "the Jupiter Theft" (with an intriguing solution to the problems of relativistic travel through space, albeit rather wasteful on planets).
There are more of course; James blish had - briefly - a planet flying among his "Cities in Flight". And obviously there's always Larry Niven with his "Fleet of Worlds" series (but again using alien tech: a reactionless drive to get the darned things moving; I bet he's kicking himself if he saw your "Planet Ships").
The title reminds me of the ''War World'' that Mongul has.
Panic in the Sky was a good crossover story in DC
Happy Arthursday everyone!!!

We need to get you on the Rogan podcast! Excellent content as always buddy!
That would be awesome...JOE?
That would be epic! Isaac would blow joes mind with different concepts and Joe would probably be so high he would be creating universes in his mind
Especially if he brings back the maths! Eyes glaze, head pops...
Holy shit yesss.
Don't think Joe would need much convincing to have him on the show tbh. I think Joe would find him pretty cool. With all the science and futurism stuff and cyborgs, hive minds, Ai, all of which interest Joe isaacs ex-military which would interest Joe. 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. I'd have never have guessed he'd had as rich of a life as he has been in wars and warzones travelled the world he breaks the stereotypical view all of the physics / science and sci-fi enthusiasts

"Moving a planet is fairly easy" - Wandering Earth 2019
"You can't crusade with a planet. Believe me, we tried."-High Marshal Helbrecht
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.
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.
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...
@@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.
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.
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 RUclips 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 !
Personally If I'm really interested in a given topic I just use it as an excuse to watch the video a couple times to get the full picture
I don't think traveling away from earth at a significant percentage of the speed of light would be desirable. New episodes on this channel wouldn't reach you once every week anymore.
They would come faster! I think.... earthlings relative to you would be aging faster? Is that how it works?
Han Solo: "That's not how light speed works!".
You know what I'm gonna do now?
I'm gonna grab a snack and watch! :)
Great video as always. But i would like to see some of the numbers your are throwing around and especially some of the math on screen to better gage the massive timelines/forces you are talking about.
Yeah, the whole channel needs actual illustrations instead of just pretty scenery.
So..after a 5 hour power outage...Drinks and munchies for me and the kiddo check! Happy Arthursday everyone!
YOU CANNOT CRUSADE WITH A PLANET! BELIEVE ME, _WE HAVE TRIED THIS!!!!!!_
Then you have not tried hard enough brother
I remember reading a short story about cat-like ppl hyperjumping near Earth and people going to mountains to avoid sudden hundred meter tall tide. Of course there was hyperjump (otherwise nice story and rather believable) and they were chased by "galactic authority".
@@tonikotinurmi9012 Are you referring to the Lyrans? Do you know where or which mountains?
Just saw The Wandering Earth movie - very well done.
Merry Arthurthursday and a happy weekend to everyone !!! 🤩🤩🤩
It would be quite amazing if one day we could detect an exoplanet with unnatural characteristics that could let astronomers on Earth conclude that it is actually a traveling planet ship.
And then build a huge net to catch it
Lets move all our icy moons into the Goldilocks zone.
That would be the the quickest way to terraform them! The ice would sublimate, forming atmospheres.
@@numberjackfiutro7412 I think life there would only last thousands, not millions of years for solar wind would grab pieces of that atmosphere. OTOH with technology one could gather some gas molecules escaping the Sun (or grab whole flares, flaresurfing but I am sure Arthur has that term copyrighted already)... hmm
Brilliant solution to the "vexing problem"!!
Awww! I thought this was gonna be a video about which planets you ship. Like, "I don't wanna sound like a total weeabo, but Neptune and Uranus are my OTP for life."
Anyone else saw the title and thought : Space 1999
😃👍
Well it was a big rectangular box covered over with glass, so magic gravity tech, by 1999 right? I always liked the stylish look to their aliens.
no...just you
I thought of "Invader Zim" where they had actual planets (not a moon) turned into actual spaceships (not a flying rock) just like in the title
No. My first thought was Flash Gordon, for which an epic, non-camp version, reboot is in order IMHO. 😎
I thought stargate universe. Is this how the ancients populated the galaxies?
The concept of a planetship colonising a new galaxy with its time moving differently to the rest of it's galaxy seems like a great idea for a story.
Agreed, I feel like the books in the "Bobiverse" trilogy if continued could tottaly pull off something like that, they even have most of the hardware already
Issac is following Schlockmercenary.com again! Geoff Who has been tracking it for years now.
Happy Arthursday!
woohoo finally im first
also isaac your videos are quite the experience all 30 minutes through
IKR - I kinda wish they were even longer sometimes.....
Imagen whole planets whizzing between systems…
- Do they need a license plate?
- Will there be aliens, issuing speeding tickets?
I need to know!
That seems impossible, as a planet needs a sun for warmth
:) Probably a good idea to watch the episode first
Isaac Arthur Okay, you made a few good points, but still, if you have a capability of moving a planet, just use spaceships and go to a new planet
Just try enjoy it ninja boy...your watching a futuristic science channel
@@ninjaman815 Whichever suits you (and these timescales, many different ideas would suit many different cultures), earlier episodes cover your idea. I've watched some episodes several times...
2000 years ago a computer seemed impossible, even storing and distribution of energy seemed waaaaay impossible.
Remember, tecnology above any time seems magic or impossible.
1:40 You know you messed up when your planet is kicked out of it's native system.
The Oarth
:v
fasto insterstello speards for hundred yeahs - this would defeat thoor porpoise
In regards to the graphic at 20:23, the waves of variability in that beam of energy were moving faster than light. Also, the whole reason I made this comment was to be pedantic and get a laugh, mainly from myself. Great video! As we all have come to expect! :)
This takes far too much effort. Better to do starlifting.
IA channel isn't for lazy ppl usually lol
F A N T A S T I C V I D E O!!!!!
The possibilities are endless - Looking forward to the next video on moving a star system!! Fun!!!!!
Could Niberu be a spaceship planet? One that has an orbit to 3200 years?
Um, first, does it exist at all?
I write this before watching the video.
I absolutely loved the concept of books "Marrow" and the sequels by Robert Reed. They were not good books, they sucked on many levels, but they did succeed in describing a world-sized ship.
The books succeeded in space and sense of vastness ... and failed miserably when describing passage of time. And thus the plots were crap.
