Question What about Massive ION Engines the size of Everest? Would they start slow, but start climbing to an eventual useful speed?

[@CC-oj5qf]

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.

[@adamwitt7788]

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.

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.

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.

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.

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.

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

[@kindlin]

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.

[@SunflowerSpotlight]

I wondered as well!

[@ArmoredNeko]

@@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.

[@lordundeadrat]

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.

[@Knight-Bishop]

@@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.

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.

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.

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 the moon contain enough material to fuel those theoretical fusion rockets?

[@CRYOKnox]

Im unsure but removing the moon would occur in more damage i think.

[@Gamelycan]

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.

[@derianvandalsen]

How about sacrificing the Moon and thus sling-shot the Earth outwards?

[@ninjahombrepalito1721]

However this does propose a good idea. We could mine fuel from other pkanets and asteroids along the way.

[@crispychocolate5359]

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.

[@montylc2001]

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.

[@TheNkflash]

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 :(

[@tobiasbandt161]

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

[@frstbyte32]

Since we’re going all sci-fi, would an antimatter fueled rocket be any better?

[@TheKurtandCoreyShow]

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]

I wonder if the earth’s structural integrity would hold under that kind of force

[@danilooliveira6580]

@@TheKurtandCoreyShow fusion is not nearly as efficient as anti-matter. anti-matter turns 100% of the matter into energy.

[@TheKurtandCoreyShow]

@@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.

[@TheKurtandCoreyShow]

@@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.

[@joshuachudley1270]

Instead of moving the earth out of the solar system....why not just move the earth into the red giants "goldilocks" zone?

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.

[@xxlordbelxx1368]

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.

[@tjrankin7474]

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?

[@yiboliang8338]

I think that formula has it.

[@elzabig1]

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?

[@josiah42]

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. kzbin.info/www/bejne/inaTn5JrprWgiK8

[@spyderbyte4271]

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.

[@James-ep2bx]

Ah you, understandably, overlooked the options a larger timescale opens up, like say planetary solar sails, and/or gravity tugs

[@DedJezter]

As well as harvesting space objects/matter as fuel resources, it doesn't all have to come from Earth

[@ninjahombrepalito1721]

And pushibg the Earth away from the sun more slowly could reduce the amount of energy needed.

[@BattGaming]

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?

[@hanneswiggenhorn2023]

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

[@gorilladisco9108]

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.

[@demi-fiendoftime3825]

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

[@Beegrene]

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.

[@alyasgrey9370]

@@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?
