Can We Turn Earth Into a Spaceship? | The Wandering Earth 

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

Anyone getting a Patrick vibe from this? ‘We need to take the *Earth* and push it somewhere else!’

Alien: “WHAT THE HELL IS THAT?!” Other Alien: “IT’S A FREAKING PLANET SPEEDING TOWARDS US!”

Because Science: "You can't turn the Earth in a spacecraft" Kurzgesagt: "How to make your own Solar System spaceship at home"

People when Earth is close to Uranus : "Look at that, Uranus is so big"

In the great words of an even greater scientist “We should take it and push it over there”

Getting Invader Zim flashbacks. Also those rockets would burn off the atmosphere when used.

Today: “We did surgery on a grape.” 3000: “We turned Africa into a jet engine!”

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.

Mars: "hey earth, where you headed off to?" Earth: "cant talk, still thrusting"

Kyle: "earth orbits the sun more or less in a circle" Kepler: am I a joke to you?

The first thing I thought of was, once we leave our sun, wouldn't we have a HUGE problem of not HAVING a sun until we arrive at Alpha Centauri?

This is legitimately a strategy that Patrick Star would come up with! 😂

“Why don’t we take Bikini Bottom and push it somewhere else...” -Patrick Star (Oct. 12, 2001)

_CAN WE TURN EARTH INTO SPACESHIP?_ *Elon Musk:* _Don't do that. Don't give me hope._

Kyle you scared the hell out of me at the end there with the “thank you so much for watching, Tedy” and I applaud you for it. I dont know the odds of me coming across a video where my name was randomly said, but I was happy to see it!

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.

Now that you've done moving the earth part, can you PLEASE do the 'igniting jupiter' part?

Kyle: Do you feel like you're moving right now? Probably not. California: Am I a joke to you?

The Wandering Earth ll is out there now! The movie is awesome! Blow my mind! Please also review and make some science video about it!

love how he tries not to laugh when he starts explaining the crazy premise

But Kyle, you forgot about our friendly surrounding neighbors. We can use them for everything needed.

No-no-no, light speed is too slow!... we're gonna have to go right to... Ludicrous speed!

if yall thinking why not build a space ship. watch the upcoming second movie.

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.

I don't know Thor... Can we? *Let's turn real life into a real movie, Asguardians of the Galaxy.*

We should throw the water on earth but first dont forget to have 2 water bucket to make infinite source again

Ive been asking this questions for years that’s awesome this video exist thank you so much !

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.

Can the earth crust even withstand the pressure from the rocket engine even if we can reach that amount of force?

Imagine that you turn on the thruster while the earth still spinning. You could make the largest beyblade in the universe.

This is, after all, a movie where everything is possible.

The concept of flying Cities, carrying manufacturing to resources in the Cosmos. Thank you, James Blish.

I'm no scientist. But my gut tells me all those rockets would destroy our atmosphere, right? Wrong?

Arthur Issac's "Planet Ships" video sums it up and goes beyond, he should be the supernerd :) great vid tho

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

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!

I'm pretty sure it would be easier to just build an actual spaceship

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.

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.

'Beautiful, isn't it. The only home we've ever known' That the reason why in the movie humans take the earth with them.Just because it's The only home we've ever known

Because Science: Can we turn earth into a spaceship? Isaac Arthur: that's level 1. Next thing: the entire solar system.

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.

"Earth is so dang heavy" Earth-chan: duck you I'm not heavy~!

This channel is seriously underrated

but if we escape the solar system, we'll die stone cold

Asteroids as fuel? There. I've made "completely implausible" into "mostly implausible."

2:12 “how much energy would be needed to FLING it out of it’s orbit?” Me: _Sees the Earth smash into a random Star Nearby._ Well, shit.

Aliens earth invasion strike group halfway heading to earth... Aliens: What the hell is that thing in front of us? Aliens captain: WTF, who are they? they are on a collision course with us! Earthlings UEG: Please divert your course 15 degrees to your right side to avoid a collision. Aliens captain: Recommend you divert your course 15 degrees to your right side to avoid a collision. Earthlings UEG: Negative. You will have to divert your course 15 degrees to your right side to avoid a collision. Aliens captain: This is the Captain of HMS krypton lance. I say again, divert YOUR course. Earthlings UEG: No. I say again, you divert YOUR course. Aliens captain: THIS IS THE HMS KRYPTON LANCE, THE FASTEST AND SECOND LARGEST STAR BATTLE SHIP IN THE KRYPTONIC EMPIRE INTERSTELLAR FLEET. WE ARE ACCOMPANIED BY 1000 STAR DESTROYERS, 5000 GALAXY CRUISERS AND ONE MILLION SUPPORT STAR SHIPS. I DEMAND THAT YOU CHANGE YOUR COURSE 15 DEGREES TO YOUR RIGHT SIDE, I SAY AGAIN, THAT'S ONE FIVE DEGREES TO YOUR RIGHT, OR COUNTER-MEASURES WILL BE UNDERTAKEN TO ENSURE THE SAFETY OF OUR FLEET. Earthlings UEG: This is a planet, over...

The most impressive feat of engineering ever? Isaac Arthur: hold my coffee.

Good explanation for a great underrated movie

12:06 ...and that's why i've always thought of this movie as a prequel to The Little Prince

Sounds like a problem for Isaac Arthur! Isaac Arthur has a video called Planet Ships that delves into this topic.

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!

This had me in tears cracking up 😂😂😂❤❤❤

It works for the movie because its a movie....but in real life,the whole concept is totally nuts!!!!!

Reads title: How d'you solve the icing problem?

Scientists from the year 3019 watching this: just use a tractor beam lol

4:00 Energetically, increasing the Earth's velocity from 30 to 42 km/s is the same (in magnitude) as slowing it all the way down to zero.

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.

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.

I freakin KNEW you couldn't resist doing an episode on this movie/book! :D

The movie version of this concept was really cool.

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.

This is like if cavemen 40,000 years ago thought: _Hey, one day we will go to the moon. Shouldn't we be working on that now?_

Humans : We might expect huge asteroids passing by. Aliens : We might expect flying earth passing by.

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?

This is Awesome !!!

8:57 I just started laughing because of how damn overkill this is conceptually

"do you feel like youre moving right now?" Me: *starts shaking violently* "YES"

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 went to sleep and woke up on this episode, cool

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?

When he said "push it somewhere else" did anyone else think of the spongebob episode when they pushed bikini bottom somewhere else to save it from the Alaskan bull worm?

I feel like this is what Sephiroth wants to do. Using the whole planet as a vessel would be really hilarious

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.

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

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.

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.

What about a gravity tractor? Rather than stopping the rotation and covering half the earth in engines

WE SHOULD TAKE BIKINI BOTTOM AND PUSH IT SOMEWHERE ELSE!

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?

This video makes Pearson's Puppeteers look themselves in the eyes.

"You can't crusade with a planet. Believe me, we tried."-High Marshal Helbrecht

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

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.

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)

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pzuHxL5FD5U.html

didn't they say in the movie that they planned to use Jupiter as a slingshot to escape the suns gravity well?

Damn this is crazy mind blown

What also shouldn't be forgotten: once you accelerate, you also need to decelerate at the destination

Isn't this just "Up" on the astronomical scale?

Zim: why would you do that? Martian: because it's cool

Thank youu🙆‍♀️🤗

You should do a video on the Kaplen Thruster.

Your necklace gives off an eerie resemblance of a vivisection. Now I cant get it out of my head

During a storyline in Schlock Mercenary, my favorite Webcomic, a race of robots overthrow their fleshbag overlords and send them out on a colony planet. However, instead of using a rocky planet, they use a gas planet. With a dual rocket system, two rockets end to end, they fire both into the planet and out of it in order to balance the rocket, using the planet's own gasses to feed the rocket. Then they just have habitats orbiting around the planet as satelites and even use the rocket as a "new sun". This whole concept was created by Larry Niven.

I think we'd be more likely to develop planetary portal technology to make that work

Idk where or when but I remember hearing about slowly pushing the Earth out of orbit wit mirrors and the power of the sun

The real question is how to prevent the Wandering Earth from freezing the moment it begins moving away from the sun.
