- World ending disasters are common place in science fiction, and usually an inventive plan is required to save the day. In the new Chinese film, The Wandering Earth, a truly unique solution is presented when the human race discovers that the Sun is dying and will soon expand, destroying the Earth-- turn the planet into it's own spaceship by building thrusters along the surface and moving it out of the Solar System. Kyle takes a closer look to find out just what it would take to pull off such a plan in this week's Because Science!

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.
So, our planet is a prison. Great video again!

@@DwarfInBlues That puny 0.017 is 5 million kilometers. Also, our orbit deforms and springs back over the course of eons. That's how you get ice ages.

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.
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.
most lack simple common sense, especially these CZcamsRS.

I knew this youtube video was from The Wandering Earth film. Absolutely loved that film too, I put it on one night because it was a chinese with english dub thinking it'd put me to sleep, ended up watching it all.
Such a fantastic movie.
This is, after all, a movie where everything is possible.
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.
@@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?
We wouldnt need to go to alpha centauri. Lets just go to the new goldilocks zone. K mr. Goldilocks?
Can the earth crust even withstand the pressure from the rocket engine even if we can reach that amount of force?
@@gb6710 haha yo mama joke funny
@@gb6710 Damn 😂
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.
@Rose arias Jenna prieto If the ground under them is soft enough they do.
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.

@@CharlesBalester last I checked that didn't work.
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.
The tzar bomba moved the Earth..
@@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
This will probably be on Because Science Footnotes
That is basically the rocket equation on a nutshell
12:06 ...and that's why i've always thought of this movie as a prequel to The Little Prince
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

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.

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.
Depends on what exactly comes out of them, but yes we should probably put their tips out of the atmosphere.
To be fair, I think that's the plan of the CCP all along.
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
If they were short enough to still be in the atmosphere, yes
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.
Worthwhile read; thanks. :)

OH my another fan of Issac here
He does good work. Just talking about this movie specifically though, because so many of you asked about it! -- kH
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.
Sounds like a problem for Isaac Arthur! Isaac Arthur has a video called Planet Ships that delves into this topic.
Jacob V exactly! moon- based Gravity Tractor
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.
Asteroids as fuel? There. I've made "completely implausible" into "mostly implausible."
What's that thing that looks like a scar around your neck? Thank you for this video, the perfect compliment to an original idea. I really enjoyed the movie, and was excited to find a video like this as soon as It was over. Much love from Oregon!
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

@@BlankPicketSign given the limit is defined in terms of.solar masses and is greater than 1.....
but if we escape the solar system, we'll die stone cold
Can I get a "hell yeah"
We'll be able to survive with cybernetic enhancements. We'll become a sort of "Cybermen" if you will.
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!
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.
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.
I'm pretty sure it would be easier to just build an actual spaceship
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

I just started laughing because of how damn overkill this is conceptually
So, the difference between 0.3% and 98+% is fairly significant, and I think a large portion of the difference could be addressed by considering more specifically the type of engine and portion of the earth, comets and asteroids used.
If we picture the engine as reaching up into the high atmosphere where heat loss and inefficiencies are less, then it's plausible that the lower .3% figure could be more relevant.
Specifically, if the crust and tectonic plates of earth were solidified and made more solid, for example by using shale oil in the crust to expand and create concrete throughout the crust of the earth closing the ring of fire, then not only could humanity prevent earthquakes and volcanoes, but we could build a large engine on a volcanic mountain, like the mountains near Argentina Chile, Bolivia, and Paraguay, that could act as a much more efficient type of rocket due to the scale, while adding water to lava which would sink to the core when solidified. The water could be refueled using comets and asteroids, and moving the planet to the orbit of Jupiter, and then using a particle accelerator built near mt Everest could induce fusion deep in Jupiters great red spot allowing us to push it towards the sun, and use star lifting to make the sun last longer, while giving us another star.
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.
Reads title: How d'you solve the icing problem?
Elon: the earth is advance in any waay
Might wanna look into it
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
"do you feel like youre moving right now?"
Me: *starts shaking violently* "YES"
U have a extra e in your
Idk where or when but I remember hearing about slowly pushing the Earth out of orbit wit mirrors and the power of the sun
Honestly, this video makes it more convincing not less. With the caveat of those insane nuclear engine speeds that 0.3% total mass of the Earth number is way better than I was expecting. Yes, we only have access currently to 1% of the Earth at the moment but like, if we are building mountain-sized engines I don't see why we wouldn't be able to overcome the engineering difficulties of pumping liquid rock directly from the mantle instead of using crust material. Heck, imagine just slapping one of your engines overtop a volcano which is already basically a hole to the mantle (I'm a chemist, not a geologist don't quote me on this.) 0.003 reduction in volume would probably be a manageable surface area loss since the earth is huge something like 2% which is a lot, but probably a similar sacrifice to building the rockets in the first place. Actually, now that I think about it we might actually GAIN useable landmass since the tectonic plates splitting under the oceans would start shrinking together instead, creating new mountain ranges and maybe even new continents. (again not a geologist)
Now please adress the consequences of stopping the Earth on its tracks and/or taking it out of the Sun's gravitational influence and heat zone.
Cronch splat
I can do that. Everyone everywhere dies. Done.
OBJECTION!!!!
I freakin KNEW you couldn't resist doing an episode on this movie/book! :D
Gravitational pushing by using some close passing asteroid has been proposed as a solution for planet moving, but there are other bodies (like Jupiter) what may throw wrench into the mix to prevent safe voyage to much higher orbit around the Sun.
I don't see this being a better idea than just jumping on a few thousand spaceships, take a big nap and arrive at Pandora in time for dinner.
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?
In that aspect, the Earth is mostly a balloon filled with (wery hot) goo. It would get completely torn apart.
Anythibg can be pushed if accelerated gently.
There is possibility, and then there is probability
@@jeremybrimmer1990 What if we just use mars and other planets and bodies in the solar system

It would be easier to just stop the sun from going Red Giant with Star Lifting.

What is Star Lifting?
xenodorian en.m.wikipedia.org/wiki/Star_lifting
@@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.
Thank youu🙆♀️🤗
Is just simpler to build large Space Stations like the Death Star to carry large numbers of people out of the solar system.
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.
Scientists from the year 3019 watching this: just use a tractor beam lol
If there are any humans left in 3019, which is really not a given already lol

This is Awesome !!!
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.
What also shouldn't be forgotten: once you accelerate, you also need to decelerate at the destination
we can go hunting for asteroids as we pass by the asteroid belt, and later the kuiper belt for fuel
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.
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.
I think we can do it (theoritically on sci-fi), in 5 steps:
1. Space mining, we mine planets, gather resources.
2. Use the resources to build extremely huge batteries and extremely huge solar panels.
3. We store solar energies for years before starting the expedition.
4. Build huge electric propulsion systems while we're waiting for the batteries to be fully charged.
5. Once it is built, and the batteries are fully charged, we can start the expedition.
This video makes Pearson's Puppeteers look themselves in the eyes.
Humans : We might expect huge asteroids passing by.
Aliens : We might expect flying earth passing by.
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".

I don't even know why he's carrying a gatling gun to begin with
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.
Disappointed that no one mentioned SHADOW RAIDERS in the comments. Each world in Shadow Raiders is discovered to be equipped with "World Engines", massive drive systems which can propel the planets through space.
I wonder if a warp field (or mass effect field) that gradually allowed to change the Earth's orbit until leaving the solar system would necessitate the same crazy energy requirements?
Warp field would be more effective if we could invent.
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
