Thanks for watching Super Nerds! It turns out that orbital mechanics is really hard when you haven't really studied it. Who knew! See you in Footnotes -- kH
It was a wonderful video, but an idea that wasn't addressed was using the moon to fuel the nuclear engines, somehow harnessing it's mass in order to lessen the amount of mass taken from Earth significantly. It's still implausible, but doing that again and again over the course of the time taken to get out of the solar system using other planets and their moons could potentially work. Only theoretically of course, as the technology required to absorb the other astral bodies is not technology we necessarily currently have, but the first step to reaching the stars could potentially be destroying Mars rather than walking on it. I'm not nearly as smart as you though, so I'm sure that there's a fault in the plan that you'd see that I don't, other than just current limitations in technology, but either way, keep up the good work.
So what you're saying is the Chinese equivalent of Hollywood isn't spinning out movies with complete garbage science? Examples of garbage movie plot points: you only use 10% of your brain, Dark Side of the Moon, "physics". Facts: you use 100% of your brain just not all of it at once because it doesn't all do the same thing, it's more accurate to call it The Far Side of the Moon because the Moon is in a locked orbit but still receives the same amount of light from the sun as Earth we just only see one side of the moon, this channel would be finished if Hollywood was more accurate according to science.
To be fair, Because Science explored what it would take to move only the earth with the goal of escaping a dying sun. Kurzgesagt's Stellar Engines video was about moving the whole solar system using the sun (even if it's partly for moving earth out of dangers like asteroids).
Also it is not elliptic the way people after Middleschool think (perihelion precession). In reality newtonian mechanics is not what you need to use in space since it is not true in bended space.
@@jackielinde7568 Iceages are almost entirely based on reasons comming from earth itself. After all the time of year earth is closest to the sun is the depth of winter for the mayority of people (around 3rd january).
Didn't even mention everyone suffocating after 2 days as the thrust nozzles blow all of the atmosphere off the planet in a giant rooster-tail wake of sadness and sparkly ice.
"Also those rockets would burn off the atmosphere when used." Preferably those rockets are burning beyond the atmosphere. Since they are taller than mountains, it isn't a completely unfeasible at least with active support.
No, it would be a matter of distributing the force across the surface and not concentrating it all at a single point. That is for the case of 'breaking' or 'puncturing' the Earth's crust. There would be another concern with 'deforming' the Earth's surface. There would need to be some method of compensation to prevent this from happening.
You Win Yeap good question! If the physics was sound and it did shear; I imagine the solution would be a quad pillared dyson sphere anchored in four points to the earth’s more stable upper crust points... though these pillars would need a lot of geologists and physics majors to watch over due to the drifting tectonic plates... its a huge undertaking to even make a model of.

Hey Kyle, love the show, and in total, I want to say that I actually really thoroughly agree with your assessment in the end, but yeah, there's a lot more I think that can be said on the subject. First of all, I think that the whole "fusion-engine" would be mandatory yes, but for more reasons than would be immediately apparent. A very large portion of the mass ejected through fusion-reactions would be ionized gasses and free-floating electrons. In other words, plasma. This is MANDATORY, as the only conceivable way to get the kinds of thrusts you'd need to have in order to produce the kinds of isp (Specific Impulse, or the level of efficiency of a rocket-engine) required would be to use a magnetic acceleration, much like ion-drives in the New Horizons mission. Basically you'd be turning the rocket-nozzles (Already the size of mount Everest) into massive particle-accelerators, accelerating the exhaust to a sizeable fraction of the speed of light to be able to get the highest isp-value possible. with isp's in the 15k+ range it IS doable. Unlikely, but do-able. Even the best ion drives today do reach somewhere close to 15k isp. So it's not impossible. Also, with the kinds of course, or trajectory you're talking about, the slow-spiral method, it makes it actually MORE efficient than a lot of other possible options. Also, you could use the slow-spiral to slow down the heating-up of the planet, as you'd be farther away from the sun. Lastly on that same subject, you could time your acceleration and vectors to sling past massive objects in the solar-system like Jupiter in a sling-shot maneuver, stealing some of their angular momentum on your way out of the solar system, to accelerate Earth fast-enough that it's feasible. This way you don't have to provide all the thrust yourself. And if you can (Like the voyager probes) can get to multiple gas-giants on your way out, it's actually a lot easier to get the velocity needed to escape the solar system. That said, there are LOTS of other problems that exist afterwards. Firstly, the atmosphere, and biosphere aren't static. So you'd need to take ALL of that below the surface. Seal off things like the volcanos and other things that spew matter out onto the surface of the planet, as almost none of that is going to survive. Also, even getting to Alpha-Centauri at 42 km/s is still going to take centuries. And then there's the problem of slowing down once you get there. Not only all of that, but you need to continue a lot of those fusion-reactors to be able to provide enough heat and power to supply the Earth with the energy it's entire bio-system needs to survive the several centuries in space. Also the Magnetosphere isn't static either, and would need to be maintained, or else the only thing keeping us safe from cosmic rays goes away... There are SO many logistical problems that need to be resolved, I don't think it's necessarily feasible, practical, or plausible. Possible? Well, nothing's impossible, lol. But highly unlikely. If you want to save a significant portion of the life on Earth there are lots of other methods. You're probably better off doing things like using a ground-based linear accelerator to accelerator generational ships out of the Solar System, leaving the planet itself to die. It's harsh, but it's a lot more likely to succeed. And if you can send enough of those ships, giving them all the technology to set up first an asteroid-based culture, I mean, you wouldn't even have to leave the solar system for that one! Start setting up shop around Jupiter, Saturn, etc. Titan, and Europa would have a pretty good chance of being liveable for at least a few million if not billion years. Giving you lots more time to spread farther, out to Alpha Centauri and beyond. Heck, visit places like Trappist, or Teagarden's Star, both close with possibly Earth-Like candidates, that would take far LESS work setting up a new Earth 2.0 than rebuilding Earth into a starship. In the end, it's just a question of what's more feasible. And this option, I think is one of the least feasible. You do manage to touch on a lot of the key points, and I'm just trying to bring to light a few of the others.
What about running nuclear reactors? They provide warmth. We can still keep the atmosphere not frozen if we take huge chunks of frozen nitrogen and oxygen over to the reactor, where it will evaporate, go up into space, and go into orbit around earth again, and repeat. We can either survive in a (frozen over) submarine (Horrible idea.) or get the required infrastructure to build all those reactors. "what about cost?" It would be the end of the world. We could tell the companies that inflate the prices "Either you give us those building blocks for reactors for free, or we all die together."
In the movie, they put everyone in underground cities that are built under the thrusters, since they provide hear. The rest of the planet does indeed completely freeze over.
We could easily move the earth to a safe place before or while it's becoming a red giant and gather fuel from asteroids to not deplete resources from earth. We are talking billions of years from now. We'll probably be visiting other planets or be dead from religious/political ideas by that time
@@donalddavenport5224 not even considering what type of technology we would likely have developed. We're talking about a civilization that would be a few rungs (if not three) on the Kardeshev scale. There exists the possibility that conventional fuel types would be irrelevant as that we would be using some sort of magic-esque engine/thrust device. Perhaps something that runs on mini blackholes?
That would be so awesome until the forces atomized... asteroidized the planet. I used the universe sim, and upped Earths rpm... it doesn't look to good when we go super fast.
Great video, but you missed a very big point. The gravity of earth would reduce the rocket engine's efficiency quite a bit, so depending on the height of the rocket, it may not even make a difference. In the case that it did have enough force to push its exhaust out of Earth's SOI(Sphere of Influence), unless the exhaust didn't collide with any large amount of gas on its way out, the force of the exhaust would slowly strip earth of its atmosphere.
@@ninjahombrepalito1721 Newton's third law, every action has an equal and opposite reaction, proves that nothing could move the earth in relation to space unless something is ejected from earth. The bomb may have shaken the earth or possibly(I haven't done any research) changed the earths rotation, but if nothing is ejected from earth, how could the earth move in a certain direction.
There is also if the earth was used to power the rockets( by sacrificing the earth's mass for fuel) the earth would become easier to move over time with less and less mass making it possible to use some mass and need less fuel
Just a few things to point out here. First off they aren't using the engines they entire way. Their getting up to speed and then coasting. Second they are also using gravity assist to reach speed. First from the sun and then followed by Jupiter where as the trailer reveals, problems arise. I wish you would have addressed those two factors in your video.
Today we're going to be discussing how to deconstruct the entirety of the Sol system to move it to another system while the Sun enters the Red Giant stage of it's life, so get a drink, and some snacks...
Naw. We'll star-mine the Sun to extend its lifespan. Remove the iron and helium and put hydrogen back into it. By doing so, we can use the sun as the engine to push us to a new solar system.
I think in one of Isaac’s episodes he mentions parking gravitational body opposite our point from the sun and using the gravitational attraction to slowly pull our orbit outward. At least enough to survive the red giant expansion, and then reversing the process to get closer to the white dwarf stage of the sun. This could extend the life of the earth by billions of years.
well if you made the rockets big enough so they'd go way beyond the edge of our atmosphere and ignite in space, i think we'd be okay. maybe. but it's firing inside our atmosphere, say goodbye to all that oxygen
how does the math change if we just raise Earth's orbit out of the surface of the new sun, and into the NEW Goldielocks' Zone? Why leave the solarsystem when we can just move to a higher, more comfortable orbit? (As if that even helps the math of this ridiculous idea XD) By the way love the show *Fistbump!
That would require much more difficult math. You would have to map a trajectory and figure out where the new orbit should be. Predicting that new orbit accurately would be difficult and if you missed you wouldn't have time to correct your error
@@Falcodrin its not like the expansion of the sun will be an overnight event, it will happen imperceptibly over the course of millennia as such you totally could just start out in about 5 million year's from now and course correct as you go/need
Agreed, the movie is quite good, but I did wonder why they didn't just build a fleet of spaceships and put as many people as possible into cryo and send them off. Considering the time and resources all this engines must have taken, I'm sure they could have easily built as many spaceships as they needed to take in the people they allowed to live in their underground cities. Besides, even if all this works, there is still the question wether or not the planet could be integrated in a new solar system once they arrived in a viable system or if the planet could be made hospitable again after the voyage, just looking for a new viable planet seems far more practical. And a bunch of spaceships would have decentralized the humans and lowered the chance of a single event wiping out humanity as a whole.
@@Neonsilver13 In the original sci-fi novel , human civilization actually splits up to two parties: the spaceship party and the Earth party. And the Earth party finally wins because spaceship party admits that they cannot build real "generation spaceship fleet" that can support a whole civilization. In my opinion it's just not a very convincing reason. But the author himself once told the truth in an interview: he called himself a solid spaceship party member, and believe that generation spaceship fleet is the form of a higher level civilization, but "the planet spaceship" is an absolutely epic sci-fi scene, so epic and thrilling that he cannot just let it go. So... it's there.
think of it in another way, if it's just building spaceships, it will be just another common scifi movie without any new ideas and lack creativity. we've seen hundreds of spaceship migration films.
@@meteorbullet3474 was there really hundreds of "spaceship migration films"? Can you name some? I would like to watch them. Or, you know, one or two will do...
If you're gonna move the planet, it would seem like more sense to push Earth further out as the sun expands, rather than kicking it out completely. But I admit, haven't watched the movie, so I'm not sure what the issue with the sun is, exactly
the problems that had to solve 40k years ago towards that end were domestication and agriculture, they managed those in a mere 25-30k. What total mad lad's, i'd have thunk i'd take twice that.
I believe those would theoretically require a fully functional Dyson Sphere and some artificial blank holes. Sure once you have that kind of tech and resources moving planets around become more feasible, but strapping rockets to a planet, fusion or otherwise I don't think will ever be a thing.
Hi Kyle! Love your videos (and envy your hair). Lets say a few thousand years from now we develop those fusion engines and that reduces the fuel and space requirements and we find a way to use the magma inside earth as a propellant. Is the earth structurally strong enough to undertake such a journey or will it fall apart like a dried lump of clay?
It also really important that the exhaust begin higher than mt Everest, because otherwise it would eject a lot of the Earth's atmosphere along with it. The thruster's exhaust needs to be higher in altitude than most of the atmosphere, and preferably higher than the ozone layer even, 'cause we kinda need that too. Keeping the planet's atmosphere along with us is kinda the whole point of making the planet itself our seedship.
@@edward3190 Without it, life as we know it wouldn’t exist. Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. - nasa how are you gonna get water without water???
@@doggy101 did you not read my last comment? a significant amount atmosphere is not lost. the atmosphere underground and the atmosphere below the thrusters are not gone
Hey Kyle You can use solar sails to accelrate earth away from the sun. But in this scenario you would need a sail with the surface area of about 4 × 10¹⁹ m² which is about 600,000 the surface area of one hemisphere of earth! You would need a circular sail with a radius of 3.6 millione kilometers! That is nearly 600 times the radius of the earth! So it doesn't matter what method you are going to use, it is really really improbable. Thnx for the video. It is so cool
It would be easier to just stop the sun from going Red Giant with Star Lifting. EDIT: Because people ask about star lifting check out Isaac Arthur's vid on it. ruclips.net/video/pzuHxL5FD5U/видео.html
@@ChemoshKamos It's a term for extracting the matter from stars. Changing how much matter a star has, would allow us to control how quickly it's burning through its fuel, but that's like "We created a solar system from scratch" levels of tech.
Yeah, the gatling gun scene was a bit unnecessary, but it wasnt really funny. It was sad; he was shooting at jupiter out of despair because they were all going to die. Nothing funny about that.
Hi Kyle, Question: would the earths crust also be able to handle the pressure of the earth rockets thrusters? Or would the tectonic plates warp so much that the rockets will end up in giant Volcano's? Love your show, Niels
Well, the mantle, while being rock, is plastic and mobile on geologic timescales. The thing is, Kyle set the timescale to be but 15 years, which is ridiculously fast for how large of an engineering project he is proposing. Knowing the sun will explode in 5 _billion_ years gives you some heads-up for preparing for and implementing the solution to the problem.
@@kindlin But in the story the sun is exploding, like right now? I didn't watch the show but I remember the sun exploded when they get to the edge of the solar system.
Oh wow, if that was the only problem this would create. The earths crust couldn't really put up with this kind of abuse, no. But you wouldn't have to worry about that because the rocket exhaust would heat the atmosphere to boiling in no time flat. You'd have to build the rockets tall enough to prevent that. Like sub orbital height. No measly little mountain sized rocket is gonna be tall enough to avoid that. Then there's the little problem of the earth quickly freezing solid as the sun becomes more distant. This would happen alarmingly fast and result in the surface becoming totally uninhabitable after just a tiny fraction of the trip. Tectonic activity would skyrocket the globe over, though. It might not shove the crust in to the mantel right away. But it wouldn't be a pleasant ride on the safe side of the planet ether. There is a safer way of ejecting the earth from the solar system. Instead of using the rockets to push the Earth. We could, instead, push much smaller (relatively speaking) objects along Earths orbit. This would require a deep time scale and countless billions of flybys. But would could eventually gravity assist the whole planet out of the solar system. We save lots of energy doing this too. As we don't have to push these other objects nearly as hard. We're just sort of redirecting them to Earth and robbing them of their orbital velocity. Do not do this. This is an awful idea. The longer you think about it. The worse it gets.
@@lordundeadrat Oh, it gets better. Or worse, I should say. I haven't seen it but I've heard and seen a bit about it. Stopping the rotation causes the oceans to wipe out a huge chunk of the population but they let it happen because they'll only be able to support a much smaller one. The planet does freeze almost right away, and it looks like most of the time anyone is outside of anything pressurized on the surface they are in environment suits; the visual effects show the planet leaving a trail behind so I'm assuming that is supposed to depict the atmosphere being blown off but I would've figured it would've been gone so quick that there wouldn't be anything left. Yet, they don't mention tectonic stuff until the main drama of the plot occurs. Get this: they decided the best place to put most of the people was in underground shelter cities adjacent to the thrusters, not in the leading hemisphere. I'm assuming to be support and repair laborers the for the systems. The rest are probably constantly mining out fuel. So, clearly they weren't thinking about pushing down on the crust. If that's where they put everyone. But, that's not all by far: they plan to use a cliché slingshot around Jupiter for an assist (and Jupiter's horrific radiation belt just seems to have been completely ignored); but apparently only NOW is when everyone suddenly remembers the Earth's tectonic system, not when coming up with the engines. The tidal effects of Jupiter start causing massive gravity-driven quakes that, among other massive issues, take some of the engines offline. Offline though, not collapsed, I think that and surface displacement are part of the explanation for why they have all that mountain's width of superstructure built around them (again not talking realism but I guess that's the idea). So... With several of the engines down, while everyone rushes to repair them, Earth starts to approach Jupiter's Roche Limit; which I believe they put faaaar too close to the visible atmosphere. You know what their big idea is? Use some of the bigger engines facing Jupiter's atmosphere to ignite the hydrogen with a particularly large, focused blast from the exhaust. Yeah. Igniting Jupiter's atmosphere with the fusion engines will simply blow the Earth away. 🤦♂️ This movie makes Mortal Engines look like a logical, reasonable approach to the end of the world. Also, like Mortal Engines, the original written story doesn't focus on the mechanics or feasibility of the setting, rather the political and personal effects the situation creates. In the novella, they don't get so close to Jupiter to have all that additional drama; rather people start to wonder if the sun is actually going to have the event predicted, and talks of the unrest and distrust that creates within the remaining population.
IF we were to use Mercury as a gravity engine (i.e. use it to accelerate the earth and moon gradually) the moon would still be orbiting the earth. We could build huge Fusion plants on the moon and build huge infrared radiators that would heat the earth was it orbited the earth.
There's an old science fiction story called "With Friends Like These" by Alan Dean Foster where humanity *does* convert all of Earth into a giant factory/spaceship. The effects this Earthship exerts are powerful enough to not only fly the Earth around space, but to bring the moon along with it.
What if instead of all of us escaping we just sent one baby to another planet, this would of course result in the baby gaining super powers because its a different sun.
@@mariosuarez6656 what if we are? All other life could be alot weaker so if it was a cool sun u know if weather was always nice on a planet a human could be pretty strong if the other sentient life is like small or something
joking or not. how sick would it be if it was true. there's no reason to think it is true, but anything is possible. a red sun should do it. or a dwarf star. you know what, i'm starting to think this might be plausible.
You're great, dude. If I had kids I would insist they check your channel out. Thanks for being so cool. You're a great inspiration to young minds everywhere. I mean, I'm 37 and I love watching your stuff. Keep up the great work.
Hey Kyle, With the mass of the moon being just over 1% the mass of the Earth, then with the fusion engine approach we could simply use that as fuel, without giving up 30% of the 1% of Earth we know and love. And another thing, with the Earth being the gravity well that traps the moon, would the moon follow the rocket-Earth through space, or would it fall behind?
If we go slow enough the moon would probably follow. Unless we get too close to other planets like Jupiter wuch would outclass earths gravity. Either pulling the moon away or pulling the moon into the earth. Depending on the moons location at the time
Cool video bro. In the movie mentioned in the beggining, they push Earth out of its orbit and use Jupiter's gravity to slingshot Earth away from the Solar System. But still I guess it wouldn't be nearly feasible lol
That is assuming 100% efficiency of thrusters. I think the opposite is much more rlevant. We'd liquefy our planet long before we move sufficient distance away. (Same applies to vast energies from the actual planet rotation that needs to be dissipated)
Hi Kyle, love the show. I couldn't help but think of the Futurama episode called Crimes of the Hot where all the robots pointed their exhaust ports up towards the sky to move the Earth in order to solve the global warming problem. Keep up the good work!
Patrick: We should take the Earth, and PUSH it somewhere else! Squidward: That idea may be just crazy enough...TO GET US ALL KILLED! Me: We'll never know till we try.
You didn't account for the earth's loss of mass while escaping the solar system, like when we throw away 1% of earth as fuel the rest of the journey will be 1% easier because the pull of the sun is now 1% weaker.
If you are going to be that picky, then you should look at how much mass the sun looses per year through the solar wind and stuff. Which I read was enough to widen the earth's orbit 1.5 centimeters per year as of now.
what is this tranfromer... you can try pushing the planet but problem with weight is there are garvityu and the earth are spinning... while spinning around the whole... a blackhole can not push it... and what the hell you think you can techlogy it.. fucking nut...
Correct. A gravity tractor would take the form of a swarm of asteroids. These asteroids would be aimed to just in front of Earth in its orbit around the sun. The asteroids' orbit would be much closer to the sun and the Earth's would be shifted outward slightly. And the asteroids could be reused repeatedly. Rigged with solar sails these asteroids would build their orbits up again then made to pass in front of the Earth again. But this scheme would take millions of years to have a significant effect on Earth. Attempting to fling the Earth into interstellar space inside of 15 years would inflict the Earth with massive catastrophe likely liquifying the Earth's crust.
If we talking futuristic technology, we would make a swarm of satellites around the sun to power some Nicoll-Dyson lasers, that would be aimed at the Moon to push it, in turn dragging Earth with it gravity.
Temporarily, but the diminishing heat from the sun would eventually cool everything down. As I pointed out before, it doesn't matter, as in the movie, everyone just hid underground.
Hey professor ♿, As a man, I have to side with Kyle on this. The most important step in our further evolution as a spieces is to a achieve optimal thrust to penetration our through this universe. Limping🥀 along isn't an option, we have as spieces if we want to have future generations succeed us. Thus, we must endeavour to thrust🤺 was as if our very lives depend upon it, and worry later about rocket 🚀 burn 🔥 after we have pierced the Vail. Sincerely, Daniel🖖🏿
Do you know /tg/'s The Ship Moves? Big E decides to ditch the Milky May, instructs mankind to build an enormous ship and even invites some xenos along for the ride. You can find it on 1d4chan, it's a great read.
Cmon kyle, great video as always, but instead of "trillion trillion" or "thousand trillion" you _can_ just say "septillion" / "quadrillion" accordingly, we'll understand, and if not, then by the visual illustration of the numbers.
the problem is in some countries quadrillion is the right number and in others it is septillion so would be inconsistent for his audience whichever way he said it.
We usually read it like in scientific notation when bigger than thousand millions (here a billion is a million millions), so "ten to the power of twenty" or whatever. I find the other nomenclature cumbersome and easy to confuse
Which is one the main reasons if we ever even can do this wecouldn't. Whatd itd do to the climate, oceans and ecosystems not to mention the lethal temperatures drop an unprecedented mass extinction would probably in record time turn us into a dead lifeless planet.
@@robertagu5533 Cooling would take ages... But yes, eventually, it could be huge trouble... Particularly, because frozen Earth would be white, thus reflecting even more of that scarce light/heat back to deep space...
@@FalkonNightsdale agree with most of what you said but it wouldn't take "ages" scientifically if the sun winked, without goin Nova on us, out everything including the appearance and receiving of light on that side of the planet would last ONLY about 8 minutes or so. Then all hell would start breaking lose. Including mass extinction, no more light means in a week tops the whole planet would be a lifeless, frozen over wasteland. Itd simply get way too cold in just a few days to be tolerable to just about everything its theorized even the very air would freeze with most the atmosphere. But everyone and thing bigger then most microbes will probably have frozen to death in the extreme cold an dark by then.
I can only imagine what the constant thundering roar of the rockets would sound like around the planet. Also I wonder how long it would take for the fire from the rockets to heat the atmosphere enough to just bake everything to a crust. As with most of Kyle's videos, fantastic thought experiment.
Sorry but the Galactic Handbook for Developed Civilizations has a whole chapter dedicated to the problem. Namely Chapter 3: Preparations and Strategies for the Red Giant Problem. Including pictuered solution! It describes the weak and the strong strategy. The weak strategy for underdeveloped species goes like this: We provide 20k larger asteroids with ion engines, and harvest with the help of swing by maneuvers from planets in higher orbit kinetic energy which we supply to the earth. After 15 million years already first successes are measurable. But it is only about staying the earth in the habitable zone of the sun. The journey to another star is the strong strategy - if e.g. a supernova is pending. For this we need a Dyson sphere / Dyson swarm to collect energy in form of antimatter. Having enough together ( I think it was 10 ^ 8 tons) we can start: We need only 1-100 thrusters. There we accelerate the masses to 99,995 % of the speed of light. Changes 1 kg to 100 kg. Some civilizations have alternatively chosen photon engines. This is also possible. Before, of course, the lithosphere must be adapted: At least 30% of the liquid lava must solidify otherwise we have an hupty dumpty scenario. And of course the journey must to be short in time. The earth surface is uninhabitable from the very start. The goal is always that the oceans do not freeze to the bottom.
Less than that even. If Earth was reduced to the same size as a cue ball, the two would be equally smooth (even Earth's deepest oceans and tallest mountains wouldn't be noticeable). In fact, reducing the Earth to such a small size, it would be impossible to have a layer of water thin enough to accurately represent the oceans.
What if we only wanted to increase the orbit diameter so that we stay in a 'habitable' zone? Without this scenario this episode feels incomplete... ;-P
Put simply, no. If the earth would be reduced down to 0.02% of its original mass, then the moon with it being 27% of earths current mass, would not have enough. In this scenario you would need to use the equivalent mass of the moon, mars, and maybe venus too.
Joseph Reynolds he ask about the Fusion rockets that requires 3% the Earth mass as a fuel. The moon is 1.2% the mass of the earth. so... no it’s doesn’t fuel the theoretical rocket to the escape velocity.
In his novel "A World Out of Time" Larry Niven moved the Earth by using another planet gravity. The theory was to move the planet close enough (Neptune in this case, using huge rockets in it's atmosphere that used the atmosphere as fuel) to Earth and it's gravity would pull Earth into orbit around it, then move the whole thing into a further out orbit. Earth eventually was moved into orbit around Jupiter. Great book, I recommend it.
Dyson swarm beaming into a light sail. Swarm (A.I. controlled) orbits sun beaming energy to a focus. Focus beams it to a catch. Catch splits it to cover sail. Sail attached to earth by multiple points drilled semi deep, 2 giant poles in N/S pole, or a "cargo net" type structure holding earth. Don't have Dyson swarms, good enough A.I. or a material strong enough to work as a anchor though :(
Build two giant mirrors on both Sides of the moon and Just slam your dyson swarm powered beam into it when the moon ist closest to the sun and again when it's furthest away, that way you can just use the moon as a gravity tractor and pull the earth away from the sun. Might be easier than turning earth into a giant 18th century galeon ;) i second the thought to use the suns energy though, No need to throw part of our planet away as rocket exhaust :D
Wouldn't that need contact with matter in order to combust? It seems like you would be using more matter for propulsion with that sort of engine. At least the human sacrifices would have a purpose, I suppose...
@@MythicalBeats997 if the rockets were evenly distributed, I would think so. That would be another reason to stop the planet from its orbit and rotation. I would think the rockets would have to be facing toward the sun to break gravity. Once you do that, there isn't much to cause drag on the planet other than other celestial bodies. I think a big concern would likely be igniting the gases in the atmosphere or just tearing the atmosphere off entirely. It'd just be safer to create a generational ship and set a course for a new world.
@@danilooliveira6580 I get that, but wouldn't you need fairly equivalent amounts of matter and anti-matter to properly power an engine like that? At that point, you have to worry about how to store that anti-matter in a safe manner and haul the equivalence of a second moon worth of it. One momentary slip up and everything is gone.
You do know it won't stay a Red Giant right? it will eventually become a White Dwarf and then we are as screwed as we are moving earth to another solar system.
Tidal force equations argue that stopping the spinning of the earth would also cause it to draw into the sun. Increasing the rate of spin however would cause us to drift away as the spin resists gravity per gyroscopic flux.
If you take into account the fact that as the earth got smaller from fusion engines, would you would need less force to propel it? And assuming fusion engines were readily available (obviously not), how much of earth's mass could it potentially save?
Nope. We can currently build steel structures that are taller than our atmosphere. Then you don't have to worry about it. Most of our atmosphere is near sea level. ruclips.net/video/TE0n_5qPmRM/видео.html
I agree that this would be a problem. If the rockets thrust was inside our atmosphere it would cause all types of problems. If you look at the screen captures from Wandering Earth the thrust is inside the atmosphere and would either destroy it or engulf the whole planet in choking smoke and whatever else comes out of a "fusion" rocket. The structure would need to be high enough that the exhaust nozzle would come out above the higher portions of the atmosphere. Not sure what something like this would do to the magnetic field. Seems like hot gas moving fast would have some reaction to it.
My question: what happens to the earth's core in this scenario? Wouldn't forcing the rotation of the earth to stop also effect the fluid dynamics happening in the core? If so how would that effect everything we depend on, even the magnetic field generated by the movement of core and mantle material?
The earthquakes would probably be devastating and having winds with 1000km/h of speed all around the equator wouldn't make it any better. The magnetic field could also suffer. The thing is, we don't stop the core from rotating, we "just" stop the crust, so the magnetic field might even stay unchanged for a good amount of time
Also what will happen to the earth's crust? Earth currently is like egg, with hard shell and gooey insides. The shell (crust) may not be able to sustain that much force, and the rockets will sink or worse, pierce through to the other side.
Most likely we would have the opposite oroblem. Not enough radiation reaching the planet. Perpetual new moon night. Not to mention how cold things would get. Probably everything would die before we reached a new solar system.
Ninja Hombrepalito Why I think if we were to do something like this build a masive ship around the earth that can provide such things while traveling through space
I think the magnetosphere is caused by the earth's rotation, so if we stopped that we'd be in trouble. As for radiation, we already get tons of that from the sun. Out in interstellar space we'd only get a tiny fraction of a percent of that.
@@Beegrene it's our core that creates the magnetosphere. If anything the concerns about radiation would be lessened the further away we were from any stars.
Oh hi, Kyle. Just a quick question: How much time do you think it would take for the thrust of all those rockets to gradually hurl our atmosphere into space along with the rockets' exhaust? Even if we could make earth move with rockets to escape a burning fiery death, wouldn't we still live on borrowed time since earth's atmosphere would slowly get thinner and thinner until there is no air left to breathe?

Question
What about Massive ION Engines the size of Everest?
Would they start slow, but start climbing to an eventual useful speed?
It was a wonderful video, but an idea that wasn't addressed was using the moon to fuel the nuclear engines, somehow harnessing it's mass in order to lessen the amount of mass taken from Earth significantly. It's still implausible, but doing that again and again over the course of the time taken to get out of the solar system using other planets and their moons could potentially work. Only theoretically of course, as the technology required to absorb the other astral bodies is not technology we necessarily currently have, but the first step to reaching the stars could potentially be destroying Mars rather than walking on it. I'm not nearly as smart as you though, so I'm sure that there's a fault in the plan that you'd see that I don't, other than just current limitations in technology, but either way, keep up the good work.
So what you're saying is the Chinese equivalent of Hollywood isn't spinning out movies with complete garbage science? Examples of garbage movie plot points: you only use 10% of your brain, Dark Side of the Moon, "physics". Facts: you use 100% of your brain just not all of it at once because it doesn't all do the same thing, it's more accurate to call it The Far Side of the Moon because the Moon is in a locked orbit but still receives the same amount of light from the sun as Earth we just only see one side of the moon, this channel would be finished if Hollywood was more accurate according to science.

No, it would be a matter of distributing the force across the surface and not concentrating it all at a single point. That is for the case of 'breaking' or 'puncturing' the Earth's crust. There would be another concern with 'deforming' the Earth's surface. There would need to be some method of compensation to prevent this from happening.

Hey Kyle, love the show, and in total, I want to say that I actually really thoroughly agree with your assessment in the end, but yeah, there's a lot more I think that can be said on the subject.
First of all, I think that the whole "fusion-engine" would be mandatory yes, but for more reasons than would be immediately apparent. A very large portion of the mass ejected through fusion-reactions would be ionized gasses and free-floating electrons. In other words, plasma. This is MANDATORY, as the only conceivable way to get the kinds of thrusts you'd need to have in order to produce the kinds of isp (Specific Impulse, or the level of efficiency of a rocket-engine) required would be to use a magnetic acceleration, much like ion-drives in the New Horizons mission. Basically you'd be turning the rocket-nozzles (Already the size of mount Everest) into massive particle-accelerators, accelerating the exhaust to a sizeable fraction of the speed of light to be able to get the highest isp-value possible.
with isp's in the 15k+ range it IS doable. Unlikely, but do-able. Even the best ion drives today do reach somewhere close to 15k isp. So it's not impossible.
Also, with the kinds of course, or trajectory you're talking about, the slow-spiral method, it makes it actually MORE efficient than a lot of other possible options. Also, you could use the slow-spiral to slow down the heating-up of the planet, as you'd be farther away from the sun. Lastly on that same subject, you could time your acceleration and vectors to sling past massive objects in the solar-system like Jupiter in a sling-shot maneuver, stealing some of their angular momentum on your way out of the solar system, to accelerate Earth fast-enough that it's feasible. This way you don't have to provide all the thrust yourself. And if you can (Like the voyager probes) can get to multiple gas-giants on your way out, it's actually a lot easier to get the velocity needed to escape the solar system.
That said, there are LOTS of other problems that exist afterwards. Firstly, the atmosphere, and biosphere aren't static. So you'd need to take ALL of that below the surface. Seal off things like the volcanos and other things that spew matter out onto the surface of the planet, as almost none of that is going to survive. Also, even getting to Alpha-Centauri at 42 km/s is still going to take centuries. And then there's the problem of slowing down once you get there.
Not only all of that, but you need to continue a lot of those fusion-reactors to be able to provide enough heat and power to supply the Earth with the energy it's entire bio-system needs to survive the several centuries in space. Also the Magnetosphere isn't static either, and would need to be maintained, or else the only thing keeping us safe from cosmic rays goes away...
There are SO many logistical problems that need to be resolved, I don't think it's necessarily feasible, practical, or plausible. Possible? Well, nothing's impossible, lol. But highly unlikely.
If you want to save a significant portion of the life on Earth there are lots of other methods. You're probably better off doing things like using a ground-based linear accelerator to accelerator generational ships out of the Solar System, leaving the planet itself to die. It's harsh, but it's a lot more likely to succeed. And if you can send enough of those ships, giving them all the technology to set up first an asteroid-based culture, I mean, you wouldn't even have to leave the solar system for that one! Start setting up shop around Jupiter, Saturn, etc. Titan, and Europa would have a pretty good chance of being liveable for at least a few million if not billion years. Giving you lots more time to spread farther, out to Alpha Centauri and beyond. Heck, visit places like Trappist, or Teagarden's Star, both close with possibly Earth-Like candidates, that would take far LESS work setting up a new Earth 2.0 than rebuilding Earth into a starship.
In the end, it's just a question of what's more feasible. And this option, I think is one of the least feasible. You do manage to touch on a lot of the key points, and I'm just trying to bring to light a few of the others.

Exactly what I was thinking!!!
well in the movie is literally iceage everywhere
@Michael Skinner i do not know what that means
What about running nuclear reactors? They provide warmth. We can still keep the atmosphere not frozen if we take huge chunks of frozen nitrogen and oxygen over to the reactor, where it will evaporate, go up into space, and go into orbit around earth again, and repeat. We can either survive in a (frozen over) submarine (Horrible idea.) or get the required infrastructure to build all those reactors. "what about cost?" It would be the end of the world. We could tell the companies that inflate the prices "Either you give us those building blocks for reactors for free, or we all die together."
In the movie, they put everyone in underground cities that are built under the thrusters, since they provide hear. The rest of the planet does indeed completely freeze over.
But Kyle, you forgot about our friendly surrounding neighbors. We can use them for everything needed.
We would definitely have time to set up massive operations pulling fuel from other planets.
We could easily move the earth to a safe place before or while it's becoming a red giant and gather fuel from asteroids to not deplete resources from earth. We are talking billions of years from now. We'll probably be visiting other planets or be dead from religious/political ideas by that time
True, but the rockets still look unfeaseble. And I think so much trust would possibly break the planet apart.

Great video, but you missed a very big point. The gravity of earth would reduce the rocket engine's efficiency quite a bit, so depending on the height of the rocket, it may not even make a difference. In the case that it did have enough force to push its exhaust out of Earth's SOI(Sphere of Influence), unless the exhaust didn't collide with any large amount of gas on its way out, the force of the exhaust would slowly strip earth of its atmosphere.

@@ninjahombrepalito1721 Newton's third law, every action has an equal and opposite reaction, proves that nothing could move the earth in relation to space unless something is ejected from earth. The bomb may have shaken the earth or possibly(I haven't done any research) changed the earths rotation, but if nothing is ejected from earth, how could the earth move in a certain direction.
There is also if the earth was used to power the rockets( by sacrificing the earth's mass for fuel) the earth would become easier to move over time with less and less mass making it possible to use some mass and need less fuel

Just a few things to point out here. First off they aren't using the engines they entire way. Their getting up to speed and then coasting. Second they are also using gravity assist to reach speed.

I think in one of Isaac’s episodes he mentions parking gravitational body opposite our point from the sun and using the gravitational attraction to slowly pull our orbit outward. At least enough to survive the red giant expansion, and then reversing the process to get closer to the white dwarf stage of the sun. This could extend the life of the earth by billions of years.
I'm no scientist. But my gut tells me all those rockets would destroy our atmosphere, right? Wrong?
Depending on the source of fuel. Destroying it? Maybe. Creating enough heat to cook everyone else? Most likely.

Agreed, the movie is quite good, but I did wonder why they didn't just build a fleet of spaceships and put as many people as possible into cryo and send them off. Considering the time and resources all this engines must have taken, I'm sure they could have easily built as many spaceships as they needed to take in the people they allowed to live in their underground cities. Besides, even if all this works, there is still the question wether or not the planet could be integrated in a new solar system once they arrived in a viable system or if the planet could be made hospitable again after the voyage, just looking for a new viable planet seems far more practical.
And a bunch of spaceships would have decentralized the humans and lowered the chance of a single event wiping out humanity as a whole.
@@Neonsilver13 In the original sci-fi novel , human civilization actually splits up to two parties: the spaceship party and the Earth party. And the Earth party finally wins because spaceship party admits that they cannot build real "generation spaceship fleet" that can support a whole civilization. In my opinion it's just not a very convincing reason. But the author himself once told the truth in an interview: he called himself a solid spaceship party member, and believe that generation spaceship fleet is the form of a higher level civilization, but "the planet spaceship" is an absolutely epic sci-fi scene, so epic and thrilling that he cannot just let it go.

I freakin KNEW you couldn't resist doing an episode on this movie/book! :D
It also really important that the exhaust begin higher than mt Everest, because otherwise it would eject a lot of the Earth's atmosphere along with it. The thruster's exhaust needs to be higher in altitude than most of the atmosphere, and preferably higher than the ozone layer even, 'cause we kinda need that too. Keeping the planet's atmosphere along with us is kinda the whole point of making the planet itself our seedship.
I don't think we would care much about atmosphere at that stage. The plan is to save the maximum number of people possible, not protecting the Earth.

@@doggy101 did you not read my last comment? a significant amount atmosphere is not lost. the atmosphere underground and the atmosphere below the thrusters are not gone
Hey Kyle
You can use solar sails to accelrate earth away from the sun.
But in this scenario you would need a sail with the surface area of about 4 × 10¹⁹ m² which is about 600,000 the surface area of one hemisphere of earth!
You would need a circular sail with a radius of 3.6 millione kilometers! That is nearly 600 times the radius of the earth!
So it doesn't matter what method you are going to use, it is really really improbable.
Thnx for the video. It is so cool
Yes, quite a lot, but still way easier to do than moving the earth using rockets.
You had my attention with your professional calculations until you used "witch" instead of "which".

@@ChemoshKamos It's a term for extracting the matter from stars. Changing how much matter a star has, would allow us to control how quickly it's burning through its fuel, but that's like "We created a solar system from scratch" levels of tech.

It would be even easier to just build colony ships totaling the volume of earth's biosphere and roam around from there.

Hi Kyle,
Question: would the earths crust also be able to handle the pressure of the earth rockets thrusters? Or would the tectonic plates warp so much that the rockets will end up in giant Volcano's?
Love your show,
Niels
Well, the mantle, while being rock, is plastic and mobile on geologic timescales. The thing is, Kyle set the timescale to be but 15 years, which is ridiculously fast for how large of an engineering project he is proposing. Knowing the sun will explode in 5 _billion_ years gives you some heads-up for preparing for and implementing the solution to the problem.
I wondered as well!
@@kindlin But in the story the sun is exploding, like right now? I didn't watch the show but I remember the sun exploded when they get to the edge of the solar system.
Oh wow, if that was the only problem this would create. The earths crust couldn't really put up with this kind of abuse, no. But you wouldn't have to worry about that because the rocket exhaust would heat the atmosphere to boiling in no time flat. You'd have to build the rockets tall enough to prevent that. Like sub orbital height. No measly little mountain sized rocket is gonna be tall enough to avoid that.
Then there's the little problem of the earth quickly freezing solid as the sun becomes more distant. This would happen alarmingly fast and result in the surface becoming totally uninhabitable after just a tiny fraction of the trip.
Tectonic activity would skyrocket the globe over, though. It might not shove the crust in to the mantel right away. But it wouldn't be a pleasant ride on the safe side of the planet ether.
There is a safer way of ejecting the earth from the solar system. Instead of using the rockets to push the Earth. We could, instead, push much smaller (relatively speaking) objects along Earths orbit. This would require a deep time scale and countless billions of flybys. But would could eventually gravity assist the whole planet out of the solar system. We save lots of energy doing this too. As we don't have to push these other objects nearly as hard. We're just sort of redirecting them to Earth and robbing them of their orbital velocity.
Do not do this. This is an awful idea. The longer you think about it. The worse it gets.
@@lordundeadrat Oh, it gets better. Or worse, I should say. I haven't seen it but I've heard and seen a bit about it. Stopping the rotation causes the oceans to wipe out a huge chunk of the population but they let it happen because they'll only be able to support a much smaller one. The planet does freeze almost right away, and it looks like most of the time anyone is outside of anything pressurized on the surface they are in environment suits; the visual effects show the planet leaving a trail behind so I'm assuming that is supposed to depict the atmosphere being blown off but I would've figured it would've been gone so quick that there wouldn't be anything left.
Yet, they don't mention tectonic stuff until the main drama of the plot occurs. Get this: they decided the best place to put most of the people was in underground shelter cities adjacent to the thrusters, not in the leading hemisphere. I'm assuming to be support and repair laborers the for the systems. The rest are probably constantly mining out fuel. So, clearly they weren't thinking about pushing down on the crust. If that's where they put everyone. But, that's not all by far: they plan to use a cliché slingshot around Jupiter for an assist (and Jupiter's horrific radiation belt just seems to have been completely ignored); but apparently only NOW is when everyone suddenly remembers the Earth's tectonic system, not when coming up with the engines. The tidal effects of Jupiter start causing massive gravity-driven quakes that, among other massive issues, take some of the engines offline. Offline though, not collapsed, I think that and surface displacement are part of the explanation for why they have all that mountain's width of superstructure built around them (again not talking realism but I guess that's the idea). So... With several of the engines down, while everyone rushes to repair them, Earth starts to approach Jupiter's Roche Limit; which I believe they put faaaar too close to the visible atmosphere. You know what their big idea is? Use some of the bigger engines facing Jupiter's atmosphere to ignite the hydrogen with a particularly large, focused blast from the exhaust. Yeah. Igniting Jupiter's atmosphere with the fusion engines will simply blow the Earth away. 🤦♂️
This movie makes Mortal Engines look like a logical, reasonable approach to the end of the world. Also, like Mortal Engines, the original written story doesn't focus on the mechanics or feasibility of the setting, rather the political and personal effects the situation creates. In the novella, they don't get so close to Jupiter to have all that additional drama; rather people start to wonder if the sun is actually going to have the event predicted, and talks of the unrest and distrust that creates within the remaining population.
Reads title: How d'you solve the icing problem?
Elon: the earth is advance in any waay

Watch the movie...it has an explanation.
IF we were to use Mercury as a gravity engine (i.e. use it to accelerate the earth and moon gradually) the moon would still be orbiting the earth. We could build huge Fusion plants on the moon and build huge infrared radiators that would heat the earth was it orbited the earth.
OMG I love you 3000 julian
There's an old science fiction story called "With Friends Like These" by Alan Dean Foster where humanity *does* convert all of Earth into a giant factory/spaceship. The effects this Earthship exerts are powerful enough to not only fly the Earth around space, but to bring the moon along with it.

@@swanclipper but why this is so much easier
@@no-np8dw because here the math it's been done by someone else....
If we used the earth as fuel we would be reducing the mass of earth so over time it would take less and less to actually push us.
Until our ONLY home burns up lol
& by the time you get to the new star system, you can add the mass back to the planet with asteroids & re-terrorform the planet.
why the sun? we could use the moon... not that she will tag along anyway
I'm fairly sure the rocket equation takes that into account.
Only works if its non renewable energy
Hey Kyle,
With the mass of the moon being just over 1% the mass of the Earth, then with the fusion engine approach we could simply use that as fuel, without giving up 30% of the 1% of Earth we know and love.
And another thing, with the Earth being the gravity well that traps the moon, would the moon follow the rocket-Earth through space, or would it fall behind?
It would probably follow
If we go slow enough the moon would probably follow. Unless we get too close to other planets like Jupiter wuch would outclass earths gravity. Either pulling the moon away or pulling the moon into the earth. Depending on the moons location at the time
If you add the moon first off you need to slow it down and then keep it from colliding with earth
I would hope so. I like tides.
@@cherrydragon3120 When that happens we just have to ignite the atmosphere of jupiter with our engines and it will explode us away safely. :)

That is assuming 100% efficiency of thrusters. I think the opposite is much more rlevant. We'd liquefy our planet long before we move sufficient distance away. (Same applies to vast energies from the actual planet rotation that needs to be dissipated)
We can make our own sun. We'd just need some really big lamps.
And that's the bottom line, 'cause Stone Cold said so!

You didn't account for the earth's loss of mass while escaping the solar system, like when we throw away 1% of earth as fuel the rest of the journey will be 1% easier because the pull of the sun is now 1% weaker.
I could be mistaken but I believe he used the Classic rocket equation which takes into account starting mas and ending mass.
Actually the rocket equation does take that into account.
@@jamesburleson1916 Correcting the corrections! -- kH
However wouldn't r in the gravitational potential energy equation increase thus reducing (very slightly) the amount of fuel needed?
If you are going to be that picky, then you should look at how much mass the sun looses per year through the solar wind and stuff. Which I read was enough to widen the earth's orbit 1.5 centimeters per year as of now.

@@campkira it was a joke/ meme question
Paint it res for speed.
What about a gravity tractor? Rather than stopping the rotation and covering half the earth in engines
Correct. A gravity tractor would take the form of a swarm of asteroids. These asteroids would be aimed to just in front of Earth in its orbit around the sun. The asteroids' orbit would be much closer to the sun and the Earth's would be shifted outward slightly.
And the asteroids could be reused repeatedly. Rigged with solar sails these asteroids would build their orbits up again then made to pass in front of the Earth again.
But this scheme would take millions of years to have a significant effect on Earth. Attempting to fling the Earth into interstellar space inside of 15 years would inflict the Earth with massive catastrophe likely liquifying the Earth's crust.
If we talking futuristic technology, we would make a swarm of satellites around the sun to power some Nicoll-Dyson lasers, that would be aimed at the Moon to push it, in turn dragging Earth with it gravity.
Simon Winn it will be negligible because the sun is bigger and the moon a thousand times smaller.
Hi Kyle
Wouldn’t the heat radiated from the rockets Heat up the earth’s atmosphere and make the planet inhospitable ?

Temporarily, but the diminishing heat from the sun would eventually cool everything down. As I pointed out before, it doesn't matter, as in the movie, everyone just hid underground.

Limping🥀 along isn't an option, we have as spieces if we want to have future generations succeed us. Thus, we must endeavour to thrust🤺 was as if our very lives depend upon it, and worry later about rocket 🚀 burn 🔥 after we have pierced the Vail.

The real question is how to prevent the Wandering Earth from freezing the moment it begins moving away from the sun.
A kugelblitz black hole propulsion would fix that.
All those rockets going off, would have to produce a lot of heat.
Which is one the main reasons if we ever even can do this wecouldn't. Whatd itd do to the climate, oceans and ecosystems not to mention the lethal temperatures drop an unprecedented mass extinction would probably in record time turn us into a dead lifeless planet.
@@robertagu5533 Cooling would take ages... But yes, eventually, it could be huge trouble... Particularly, because frozen Earth would be white, thus reflecting even more of that scarce light/heat back to deep space...
@@FalkonNightsdale agree with most of what you said but it wouldn't take "ages" scientifically if the sun winked, without goin Nova on us, out everything including the appearance and receiving of light on that side of the planet would last ONLY about 8 minutes or so. Then all hell would start breaking lose. Including mass extinction, no more light means in a week tops the whole planet would be a lifeless, frozen over wasteland. Itd simply get way too cold in just a few days to be tolerable to just about everything its theorized even the very air would freeze with most the atmosphere. But everyone and thing bigger then most microbes will probably have frozen to death in the extreme cold an dark by then.
Zim: why would you do that?
Martian: because it's cool
Finally someone with the Zim reference
I can only imagine what the constant thundering roar of the rockets would sound like around the planet. Also I wonder how long it would take for the fire from the rockets to heat the atmosphere enough to just bake everything to a crust. As with most of Kyle's videos, fantastic thought experiment.
Sorry but the Galactic Handbook for Developed Civilizations has a whole chapter dedicated to the problem. Namely Chapter 3: Preparations and Strategies for the Red Giant Problem. Including pictuered solution!
It describes the weak and the strong strategy.
The weak strategy for underdeveloped species goes like this: We provide 20k larger asteroids with ion engines, and harvest with the help of swing by maneuvers from planets in higher orbit kinetic energy which we supply to the earth. After 15 million years already first successes are measurable. But it is only about staying the earth in the habitable zone of the sun.
The journey to another star is the strong strategy - if e.g. a supernova is pending.
For this we need a Dyson sphere / Dyson swarm to collect energy in form of antimatter. Having enough together ( I think it was 10 ^ 8 tons) we can start: We need only 1-100 thrusters. There we accelerate the masses to 99,995 % of the speed of light. Changes 1 kg to 100 kg. Some civilizations have alternatively chosen photon engines. This is also possible. Before, of course, the lithosphere must be adapted: At least 30% of the liquid lava must solidify otherwise we have an hupty dumpty scenario. And of course the journey must to be short in time. The earth surface is uninhabitable from the very start. The goal is always that the oceans do not freeze to the bottom.
Biofilm you say... so basically to an object the size of the earth, we are little more than just a sticky goo all over it?
Hopefully the Earth doesn't shower very often.
We're like a layer of sweat and crusties at best.
Less than that even. If Earth was reduced to the same size as a cue ball, the two would be equally smooth (even Earth's deepest oceans and tallest mountains wouldn't be noticeable). In fact, reducing the Earth to such a small size, it would be impossible to have a layer of water thin enough to accurately represent the oceans.
Not sure why moving the earth if we only maybe less than 1% of it at the first place?
@@michaellam5355 I'm sorry?
What if we only wanted to increase the orbit diameter so that we stay in a 'habitable' zone? Without this scenario this episode feels incomplete... ;-P

@@brindlekintales I think zillion is a bit exaggerated, but yes, good point.
Zeke Hyperbole Krahlin.
If the earth's orbit diameter could be increased it would allow humans time to develop the next generation of technology to solve what happens next.
Would Pluto be in the habitable zone at that point?
Would the moon contain enough material to fuel those theoretical fusion rockets?
Im unsure but removing the moon would occur in more damage i think.
Put simply, no. If the earth would be reduced down to 0.02% of its original mass, then the moon with it being 27% of earths current mass, would not have enough. In this scenario you would need to use the equivalent mass of the moon, mars, and maybe venus too.
How about sacrificing the Moon and thus sling-shot the Earth outwards?
However this does propose a good idea. We could mine fuel from other pkanets and asteroids along the way.
Joseph Reynolds he ask about the Fusion rockets that requires 3% the Earth mass as a fuel. The moon is 1.2% the mass of the earth. so... no it’s doesn’t fuel the theoretical rocket to the escape velocity.
In his novel "A World Out of Time" Larry Niven moved the Earth by using another planet gravity. The theory was to move the planet close enough (Neptune in this case, using huge rockets in it's atmosphere that used the atmosphere as fuel) to Earth and it's gravity would pull Earth into orbit around it, then move the whole thing into a further out orbit. Earth eventually was moved into orbit around Jupiter. Great book, I recommend it.
Dyson swarm beaming into a light sail. Swarm (A.I. controlled) orbits sun beaming energy to a focus. Focus beams it to a catch. Catch splits it to cover sail. Sail attached to earth by multiple points drilled semi deep, 2 giant poles in N/S pole, or a "cargo net" type structure holding earth. Don't have Dyson swarms, good enough A.I. or a material strong enough to work as a anchor though :(
Build two giant mirrors on both Sides of the moon and Just slam your dyson swarm powered beam into it when the moon ist closest to the sun and again when it's furthest away, that way you can just use the moon as a gravity tractor and pull the earth away from the sun. Might be easier than turning earth into a giant 18th century galeon ;)
i second the thought to use the suns energy though, No need to throw part of our planet away as rocket exhaust :D
Since we’re going all sci-fi, would an antimatter fueled rocket be any better?
Wouldn't that need contact with matter in order to combust? It seems like you would be using more matter for propulsion with that sort of engine.
At least the human sacrifices would have a purpose, I suppose...
I wonder if the earth’s structural integrity would hold under that kind of force
@@TheKurtandCoreyShow fusion is not nearly as efficient as anti-matter. anti-matter turns 100% of the matter into energy.
@@MythicalBeats997 if the rockets were evenly distributed, I would think so. That would be another reason to stop the planet from its orbit and rotation. I would think the rockets would have to be facing toward the sun to break gravity. Once you do that, there isn't much to cause drag on the planet other than other celestial bodies. I think a big concern would likely be igniting the gases in the atmosphere or just tearing the atmosphere off entirely.
It'd just be safer to create a generational ship and set a course for a new world.
@@danilooliveira6580 I get that, but wouldn't you need fairly equivalent amounts of matter and anti-matter to properly power an engine like that? At that point, you have to worry about how to store that anti-matter in a safe manner and haul the equivalence of a second moon worth of it. One momentary slip up and everything is gone.
Instead of moving the earth out of the solar system....why not just move the earth into the red giants "goldilocks" zone?
This makes more sense since it will takes millions of years before the sun goes supper nova.
That’s allmost what I asked when I saw wandering earth movie, why don’t they use all Rocket to started the rotation again?
Literally my first thought.
@@emilandreasson9670 They used the Torgue Engines around the Equator to stop earth Rotation.
You do know it won't stay a Red Giant right? it will eventually become a White Dwarf and then we are as screwed as we are moving earth to another solar system.
Tidal force equations argue that stopping the spinning of the earth would also cause it to draw into the sun. Increasing the rate of spin however would cause us to drift away as the spin resists gravity per gyroscopic flux.
If you take into account the fact that as the earth got smaller from fusion engines, would you would need less force to propel it? And assuming fusion engines were readily available (obviously not), how much of earth's mass could it potentially save?
I think that formula has it.
A whole nother thing I'm guessing but wouldn't the rockets just punch a hole in our ozone layer radiation in and other bad stuff?
Nope. We can currently build steel structures that are taller than our atmosphere. Then you don't have to worry about it. Most of our atmosphere is near sea level. ruclips.net/video/TE0n_5qPmRM/видео.html
I agree that this would be a problem. If the rockets thrust was inside our atmosphere it would cause all types of problems. If you look at the screen captures from Wandering Earth the thrust is inside the atmosphere and would either destroy it or engulf the whole planet in choking smoke and whatever else comes out of a "fusion" rocket. The structure would need to be high enough that the exhaust nozzle would come out above the higher portions of the atmosphere. Not sure what something like this would do to the magnetic field. Seems like hot gas moving fast would have some reaction to it.
Ah you, understandably, overlooked the options a larger timescale opens up, like say planetary solar sails, and/or gravity tugs
As well as harvesting space objects/matter as fuel resources, it doesn't all have to come from Earth
And pushibg the Earth away from the sun more slowly could reduce the amount of energy needed.
My question: what happens to the earth's core in this scenario? Wouldn't forcing the rotation of the earth to stop also effect the fluid dynamics happening in the core? If so how would that effect everything we depend on, even the magnetic field generated by the movement of core and mantle material?
The earthquakes would probably be devastating and having winds with 1000km/h of speed all around the equator wouldn't make it any better. The magnetic field could also suffer. The thing is, we don't stop the core from rotating, we "just" stop the crust, so the magnetic field might even stay unchanged for a good amount of time
Also what will happen to the earth's crust? Earth currently is like egg, with hard shell and gooey insides. The shell (crust) may not be able to sustain that much force, and the rockets will sink or worse, pierce through to the other side.
Somebody been smokin some weed man.
I'm curious about the effect of random cosmic radiation on the Earth and magneto sphere during a trip to another solar system.
Dr.Jex___ Which is why best build some sort of Sheild for such important things
Most likely we would have the opposite oroblem. Not enough radiation reaching the planet. Perpetual new moon night. Not to mention how cold things would get. Probably everything would die before we reached a new solar system.
Ninja Hombrepalito Why I think if we were to do something like this build a masive ship around the earth that can provide such things while traveling through space
I think the magnetosphere is caused by the earth's rotation, so if we stopped that we'd be in trouble. As for radiation, we already get tons of that from the sun. Out in interstellar space we'd only get a tiny fraction of a percent of that.
@@Beegrene it's our core that creates the magnetosphere. If anything the concerns about radiation would be lessened the further away we were from any stars.

Oh hi, Kyle. Just a quick question:
How much time do you think it would take for the thrust of all those rockets to gradually hurl our atmosphere into space along with the rockets' exhaust? Even if we could make earth move with rockets to escape a burning fiery death, wouldn't we still live on borrowed time since earth's atmosphere would slowly get thinner and thinner until there is no air left to breathe?
