Haven't watched the whole video yet, but as a non-expert, I would think Earth becoming a rogue planet would be less than ideal for all life on Earth.

I always think of Juggler of Worlds for planets decoupled from their stars. Not quite the same, that story features 5 planets in a Klemperer rosette orbiting a mutual barycenter as they traverse their way out of the galactic plane. The planets are lit and heated by artificial fusion powered satellite suns in orbit around them.

[@CharChar2121]

Alright, idea for a story: the earth is destined to become a rogue planet. Two desperate plans are concocted: those that can afford it leave on the arks. Everyone else moves underground. Neither was a good option; those on the arks knew they had nowhere to go. Those underground understood that they were unlikely to ever see the stars again. The two groups made a pact that the earthbound would leave a beacon in orbit so that anyone who found it would know that someone was trapped. They hoped that eventually, they would find eachother agaun, but doubted it. A few hundred thousand years go by. The earthbound are fine. In fact, they're doing well. However, much of their history has become myth as firmly believed to be true as the Greek myths. The ark people have barely survived, but their knowledge of the past is better. Still, it is more a legend than a myth, but some believe it. Anyway, the arklings pick up the signal and believe they are aliens. In many ways, they are; while both are humanoid, their bodies and minds have diverged quite a lot, to the point that they could be mistaken for aliens. So the arklings pick up the signal and decide to investigate. It costs them greatly; the entire industry of the kingdoms (it's a funeral system) is committed to investigating the planet. The beacon, as they get closer, transmits a song that is inexplicably pleasing to the Arkling's ears in a way that something so alien shouldn't be. They get there and see a symbol on the beacon that was passed through millenia in stories, carved into floorboards, in paintings,drawings, and is such a part of their culture that it shows up on some flags; the symbol for "Unity." That was the name of the Pact; the Unity Pact. So this gets people wild and after being unable to contact anyone in the earth, they start digging. The encounter, when they meet, is incredibly tense. The Earthbound have become significantly smaller than any human, but they're not dwarves. Closer to tiny elves, really. very slender, unbelievable white skin, silver iris...the arklings show the symbol for Unity and are immediately taken to the king of the colony they find. The king sees the symbol and begins crying. Like the arklings, the symbol has been passed through generations, but the meaning was lost. It was the symbol for every underground civilization, it turns out. Not all did great, but some did better. They range from apocalyptic tunnel monsters to technocratic paradises where everyone has become robots. Yet, they all use this symbol.

[@virutech32]

Got some anachronism over there with the history becoming myth...scratching stories into the "floorboards" & all that. This is all stuff that's gunna be recorded & stored by both parties. mind you it's a lot of time for misinformation to take it's toll but cross-referencing each others histories would likely fix that. also the subterraneans have no reason to evolve small & all that. They live in human-sized well lit buildings. There are no selective pressures to go that way. Also after a few hundred years they will be back to advancing science & they would still have space travel tech from the bigging. We have the tech to go interstellar now so i imagine that's some info they'd keep & use regularly

[@prawnmikus]

If we were a rogue planet, could we place thousands of tiny artificial suns in low/medium orbit? These would be fusion reactors designed to output heat and light at Earth. Also increase atmospheric CO2 to a few parts per thousand, or whatever the oceans could tolerate. Between the reactors we could place mirrors as well -- basically we provide heat and light for the planet and blanket ourselves as best we can.

Also, Stirling engines are some of the best things to hook up to a generator (or be a generator in some designs) ESPECIALLY where there are extreme temperature gradients (in this case molten rock on the hot side and frozen nitrogen side on the cold side...can't get much more ideal AND they don't use fuel to run).

[@UteChewb]

One thing to mention. The further into the Earth you dig for cities, the warmer it gets, generally. About 25 deg C / km. That would save a lot on heating and allow the use of temperature gradients for energy production. But it would cause a problem because of the need for enhanced ventilation. So dig down far enough to keep the habitable areas at about the right temperature, and then dig shafts much further down for geothermal energy.

[@Tuzszo]

An interesting consequence of the Landauer limit and other thermal limitations on computing is that a post-biological (or bioborged) civilization might intentionally do this to their own planet to take advantage of the increased efficiency from the cold. They might even go as far as artificially cooling the planet further, meaning you could end up with planets cold enough to have oceans of liquid hydrogen or even helium if they went really crazy with it. This would invert our usual assumptions about the population distribution of said societies too: instead of dense populations surrounding the warm regions close to stars with sparse amounts of small habitats floating around between, you would find sparse populations living close to stars to extract resources while the cold voids between would be the big population centers.

[@virutech32]

well they'd probably want to be densely packed for minimizing comms lag so they'd be turning stars off & going as compact as heat rejection lets them with less dense swarms out around every rouge body larger than 100km accrros. Or maybe you'd get just that one dense swarm with everything else being auto harvesters. who knows

[@hubertseidl93]

before I even watched your video (just saw the title), I already thought about it: if it happens immediately, we are virtually done. if we find a planet that happens to pass earth in 10-15 years (from now) and would more or less eject earth from the solar system (in theory, earth could even just be yanked into a highly eliptical orbit). first stage: ramp up agricultural production, we need to be able to run on batteries for some time. second stage: we need to find energy sources. nuclear is a massive option, but takes some time to ramp up. fossile sources would add greenhouse gasses, but once we leave our regular orbit, that would actually help. besides, there is a technology in the works, that allows drilling holes for up to 20km dept. this could supply us with energy for a looong time. third stage: even if we manage to keep ourselves warm, the biosphere is gone. we need to freeze animals, plants, fungi, seeds, bacteria, etc (and people who we can't rescue to survivie, just give them a chance). fourth stage: soon after the ejection, we need to have a food production running for many of us (hydroponics, aeroponics, algae). there will be deaths, this is unavoidable. I think, a lot of people will be living in submerged cities in the oceans, because ice is a good insulator. fifth stage: we need to salvage everything from the surface. the atmosphere should be now fluid, but it would be at most a 20m deep sea above our regular ice-oceans. the ecological balance will be gone, everything will be frozen, but we could survive. the biggest problem besides of not having sunlight in the longterm will be seismic activities, either by the low temperatures on the surface, or by using geothermal energy. so, we will lose a significant percentage of the population, but we can survive. and our bunkers need to be stable enough to endure those earthquakes. long term: dig down deeper and deeper, until we dismantle earth with all the fun technologies like orbital rings, etc. maybe, a few thousand years later, we reach another star, but earth got turned into a massive spaceship.

Love your channel and although I have no real problem understanding you , I do appreciate the closed captions.,. Do keep up the work I do enjoy it.

[@Embassy_of_Jupiter]

If any city could survive Earth becoming a rogue planet suddenly, it would probably be the area around Shenzhen. They have the infrastructure knowhow to keep a technological civilization going, they have a nuclear power plant and district heating/cooling that could probably be hooked up to the power plant, to generate heat during the transition to living underground.

[@Tuzszo]

Are there deposits of fissionable elements around Shenzhen? I imagine that keeping extended supply lines open during the apocalypse would be easier said than done, especially as the whole planet got buried in ice.

Hi Isaac, I enjoy watching your content from my home in Jamaica. Great job.

[@AnimeShinigami13]

a very popular view of this scenario involves dark matter passing close enough to our system to sideswipe a chunk of it out of orbit and into the great beyond. how likely is this to happen? and if not likely, just how much hooey is it? would a gamma ray burst have the ability to disrupt orbits from it's light pressure?

[@troyjones1976]

My understanding (based on half-remembering Isaac's video about dark matter from a while back) is that we don't know enough about dark matter to be able to say how likely something like that would be, or if it is even possible. But common sense suggests that if interloping blobs of rogue dark matter ejecting planets from the solar system were super frequent, we would have already been ejected long ago, so I wouldn't worry. As for gamma ray bursts, I suspect if we are getting blasted by gamma rays strong enough to perturb our orbit even slightly just from the light pressure, then that orbital perturbation will actually be the least of our worries (compared to being roasted by gamma rays, I mean).

[@sirlight4954]

Our current understanding of dark matter is that it is much more diffuse than ordinary matter, because most processes that clump matter together (like star or galaxy formation) require electromagnetic interactions i.e. collisions. DM colliding with itself probably does not loose momentum enough to stop and clump together due to lack of EM interactions. Therefore, a cloud of dark matter passing through our solar system will likely be of an order of magnitude larger than the entire solar system, which will not cause significant perturbations in the individual planet orbits

[@paulwalsh2344]

Depends on if they're MACHOs or WIMPs... if MACHOs, then Isaac proposed some scenarios. If, WIMPs, we don't have any viable candidates or scenarios for them to conglomerate together. As for the light pressure from GRBs, it's a super massive burst of light and gamma rays, but for a very short period of time so negligible on the solid mass of a planet, so you wouldn't have sustained light pressure acting on masses. GRBs are mostly due to giant supernovae and the ejecta of solar material in the supernova would be the initial kick for planetary ejection. The black hole left after this supernova would logically be less massive than the progenitor star and that would be the mechanism for planetary ejection..

[@entropiated9020]

In essence, this sort of scenario could turn us into a Europa type world dependent only on non-solar forces to create internal heat. But even if we managed to adapt to living underground, the air won't last forever. perhaps nuclear energy could take up the load by providing heat, melting ice and splitting water into hydrogen and oxygen to keep replenishing our atmosphere, such as it is under ground

[@himynameis3664]

Oxygen is only a very small percentage of what we breathe though

[@Embassy_of_Jupiter]

Air won't be a problem for a long time, there is a LOT of Oxygen in our atmosphere and there won't be anything to breathe it. Even if it would disappear, you can easily make water from electrolysis of rocks and it only takes a couple hundred watts per person. Oxygen is the most abundant element in our crust after all. And like you said, you can split water or even CO2 if you use fossil fuels. Humans don't use a lot of oxygen compared to industrial processes.

[@Embassy_of_Jupiter]

@@himynameis3664 You only need the oxygen though, and you could suck up the nitrogen from the surface as gas or liquid. It's inert so it won't disappear.

[@maxwelllittle5291]

Has anyone ran the numbers on whether Geothermal heat flux would be enough to maintain liquid water either near the mid-ocean ridges or within deep trenches? A few kilometers of ice would be quite a good insulator and the decay of Uranium and Thorium will keep supplying energy for billions of years even without taking into account the tidal heating caused by whatever ejects Earth.

[@Tuzszo]

It should be more than enough. Afaik all of Jupiter's Galilean moons (except Io) are expected to have subsurface oceans while their internal heating is substantially less than Earth's. Io has 1.5-4 times more internal heating than Earth and whatever surface water it may have once had boiled away because of it.

Someone who watches sfia could make a scifi show like startrek set in a dyson swarm with only current technology (no ftl, teleportation, anti-gravity or other 'magic' technology.) You might include advanced concepts like moving the entire star or striping matter off of it. Or there could be examples of ridiculous magastructures that were only built for fun/"because we can" I think such a setting could have all kinds of interesting stories in it. And you could have a relatively crowded space without going outside whats plausible like most other scifi shows

the mention of re-entry made me think, what is it like to aerobrake or lithobrake a planet or moon that was just transferred between two parent celestial bodies? Would it be feasible to dip the surface of the earth into the atmosphere of another sun while trying to capture around it? especially if the surface of the planet is no longer used, it might be acceptable to just burn away part of the crust (probably just a few meters of soil) during aerobraking to assist in capture to another system.

I love these Thursday episodes. In anticipation of this particular episode I started thinking about rogue planets. That lead me to thinking about something that I don't believe that I have thought of before. A planetary system without a star at its center. I am imagining a terrestrial planet with roughly the mass of our sun at the center. It would most likely have relatively little hydrogen and be composed of the heavier elements. This central planet could then have more conventional planets orbiting it. Sorry, it was just a wild thought that I wanted to share.

[@uncleanunicorn4571]

How would the planets form?

[@virutech32]

Any collection of matter with stellar mass would keep all the hydrogen it started with or quickly colllect a bunch so no realistic way for that to form naturally. Even if it for some reason it didn't have any hydrogen, but still had a star's worth of matter it would immediately collapse into a white dwarf as fusion is the only thing that keeps a stellar mass object from collapsing.

[@FQuainton]

@@uncleanunicorn4571 my guess is that they would form from a planetary disk. Just my guess though.

[@barahng]

Look up Juggler of Worlds by Larry Niven, somewhat similar to what you're describing.

[@FQuainton]

@@barahng Larry Niven is an amazing author. I love his Ringworld series.

The Wandering Earth is a good movie about this concept, on Netflix. Underground cities and big planetary thrusters.

An entire video on earth wandering through space and not one mention of the great movie The Wandering Earth?

My first guess is that it might solve global warming.

There is a 2019 Chinese Sci-fi movie called The Wandering Earth, an adaption from a novel with the same name. It depicts exactly this scenario, except it was the sun was dying and humans had to shoot the earth into space and plan to arrive in the Alpha-Centauri system several thousand of years in the future. During this time people will be living in underground cities. It is quite a nice movie.

Fun video love your stuff

Earth could multi- class Druid/Rogue/Warrior In honor of Thor, Gaia, and Loki..... I'm just not down with being a rogue only planet... Anybody know the D.M. and how to get ahold of him?

[@mill2712]

Interesting you used 2 Nordic gods and 1 Greek goddess.

[@rickstorm4198]

Gaia was a Titan/Giantess technically and was Thor's mother also known as Jord and a few other names.... . It's why Odin trusted Midgard to Thor. Since he was half/half and of the earth. Truthfully, all religions are so intertwined...... Christianity has many elements of Pagan, Egyptian, Greek, Roman etc....such as the calender Tuesday being Tyr's day, Wednesday day being Woden's day (Odin) Thursday/Thor...Friday Frigga Saturday/Saturn ,Sunday for the Sun or Ra, Monday is fir selune Monday iirc.... Tons of stuff....

[@ericl1280]

Our fozen-ice surface would have too high a reflectivity for us to Hide in Shadows. Better drop the Rogue class and keep the others.

Falling object from the sky received a different scale in my mind because of russian rockets falling near by. Even without detonation, it falls with a loud sound and shake a house. Windows are broken around very often.

If the sun came with us but we were kicked out of the galaxy everything would be ok except the night sky.

Great episode. I think my copy of the Hitchhiker's Guide might've been missing an important chapter. Also, if some other civilization had their rogue home world headed our way, how far away would we likely detect the incoming earth-sized iceball?

I'm interested in how much HEATING of the planet would occur, due to being yanked out of orbit. Was that addressed here, and I just missed it?

[@virutech32]

and maybe earthquakes🤔

[@Runetrantor]

Have you ever seen the show 'Evacuate Earth'? It covered several such topics. Some with more love than others (the frozen Earth one for example ended with 'mole people' horrible scenario, not thriving underground civilizations)

[@cast_outlaw]

Oh a new one I’m going to listen to this later at work while burning down roles of roofing (dang there is no torch on roofing emoji😂)

It would be like turning earth into a generational starship

[@Gaehhn]

Isaac also has a Video on doing exactly that. See Episode "Planet Ships".

[@thomasmaiden3356]

Zoe The Robot told me that "If the earth became a roque planet, the empire would quickly swoop in and whip us back into shape."

[@illusivemusings]

what hurts the most about that opening line(as a creative) is when you realize it was written in the Bible, meaning the sentiment existed even before that.

[@GoblinsCorner]

I'd expect it more likely that Earth ends up engaged in a death spiral with the sun or smashing into another planet due to orbital dynamics, but it's interesting to consider the possibilities of getting ejected. Certainly one way to travel!

[@51bookworm]

In a billiard ball hit, throwing earth OUT is much more likely.

[@mbabcock111]

I was literally thinking about this a few days ago.

[@garyjust.johnson1436]

Soooooo..... The Vogons could've just moved the Earth to make a hyper space bypass? And the Empire never needed a planet destroying Death Star, just a fleet of tugs to move a planet? Great video! Very thought provoking! Can you do a video about your views on the current crop of sci-fi movies and tv shows? I would like to hear what mr. Arthur thinks of New Dune and Moonfall. And Don't look up too!

[@bbirda1287]

Well, they did post that notice, so Earth should have had plenty of time to take care of it themselves. Can't just go giving charity to every little planet, they have to take some responsibility for themselves. It's just responsible economic governance. Citizen's taxes and all that.

[@harvbegal6868]

Yes. But a fleet of tug ships just doesn't have that shock and awe factor.

[@I-am-awayTOM]

If earth becomes a rogue planet... Do we all have to dress like samurai? Great episode! Scary if ever I become immortal.

Would preservation even work though, I’ve always heard that tissue destruction is inevitable with current methods. The civilization would have to manufacture all the technology they plan on using in the long run. Computer processors can eventually deteriorate, any moving part will inevitably wear out. One factory alone can take up as much space as a college campus, and you need to be able to make all the parts in that factory with other factories we’ve built.

[@virutech32]

People could still be frozen for over a thousand years which is a long time to be working on a problem & expanding our life-support capacity. People could also be prepared by flushing radioisotopes out of our system to last longer. As for manufacturing we would probably largely rely on surface factories & slowly encapsulate the critical stuff that couldn't be moved downside. Could easily insulate the already existing factories. Though space is not likely at a premium. Definitely not if they're using plants to make our food so there's no problem continuing construction after you go underground
