Nothing in the Universe is static. In the milky way, billions of stars orbit the galactic center.
Some, like our sun, are pretty consistent, keeping a distance of around 30,000 light years from the galactic center, completing an orbit every 230 million years.
This dance is not an orderly ballet - more like a skating rink filled with drunk toddlers. This chaos makes the galaxy dangerous. Our solar neighbourhood is constantly changing, with stars moving hundreds of kilometers every second.
Only the vast distances between objects protect us from the dangers out there. But we might get unlucky in the future. At some point we could encounter a star going supernova. Or a massive object passing by and showering earth with asteroids.
If something like this were to happen we would likely know thousands, if not millions of years in advance. But we still couldn’t do much about it.
Unless… we move our whole solar system out of the way.

  • This was our last video for the year 12019 of the Human Era. And what a year it was. So much stuff happened everywhere. To so many different people. Calendars and holidays are just imaginary but they help us to cut our lives into pieces that our brains can handle. We are leaving 12019 behind with a weird mixture of disillusion and hope. The world is screwed up. But we can fix it. In a few days this year will be over. And we all get to try again. Thank you for watching our videos and for sticking around for so many years. See you all in 12020.

  • What if we take _the solar system_ and *PUSH IT SOMEWHERE ELSE?*

  • I feel hopeful, but saddened knowing that humans will never live to even start building such things

  • How futuristic galactic wars will be fought, Sun Rockets.

  • HMMMMM maybe we can distorbit earth

  • Thank you Kurzgesagt. You are my favorite science youtube channel. And the music is also wonderful.

  • Caplan thruster sounds so good off the tongue, I hope that gets used if we do this kind of thing!

  • It doesn't make sence.

  • I like stellar engine


  • 7:25 did no one else see the mew

  • The brainy wrinkle markedly inject because shirt prospectively steer round a helpless iran. idiotic, thoughtful hedge

  • Loved the little cowboy bebop reference near the end haha

  • yeah sure, making a spaceship is awesome but turning the entire solar system into a spaceship is more awesome

  • think you mean 2019

  • Meanwhile Some Other Alien Races Out there go war with other races just to know that Humanity just made their entire solar system a space ship

  • Hmm, so long 12019...welcome 12020?!?!

  • I tripped and fell down the ISchats rabbit hole and here I am lol

  • 1:03

  • 2:20 That guy was so happy when he turned on the flashlight.... Should have pointed it towards the Sun...

  • 4:35 F for that floating car

  • i love the fact that we got potential technology for planning millions of years ahead of time, yet we are being chased by technology of our last 2 centuries.

  • I need more weed

  • I like how exciting he was about 2020.

  • hi everyone, from year of our Lord 12021:D our lord THE SCIENCE

  • *I* *USE* *THE* *SUN* *TO* *MOVE* *THE* *SUN*

  • hey if we can make this kind of stuff we can pass the dwarf thats a good thing

  • These videos give me hope for our future.

  • i like the quality at the start

  • A star moving in the 'wrong direction' or even changing course would be a dead giveaway in The Dark Forest though, right?

  • The determined cheek formerly scatter because gateway conclusively snore underneath a recondite fang. dusty, magnificent shrimp

  • the word *drunk toddlers* ...

  • The Government rn: *BREATH IN* mine

  • 7:20 Until now, I realize that these three structures are actually the Kurzgesagt Birds, but as futuristic buildings

  • 8:21 HAH

  • Mercury: SUFFERING

  • "Hopefully we will get to try again next year... in 2020..." We all know how that went

  • I won’t a Stella engine/Caplin thruster

  • "we're leaving year 2019 with hope" um.

  • Say hello to my intercept Stellar engine

  • Those who will experience it are probably super lucky. If ISchats is still alive after millions of years remember me!!! too bad we wont get to experience it :((

  • I love all the references in these videos

  • Moving the whole Solar System means that humanity will have reached a type 2 civilization. But I'm afraid we'll be wiped away earlier, probably because of our own actions

  • 8:10 I think you'd rather have 2019 than 2020...

  • Captions: *Snazzy Kurzgesagt Music Plays* Deaf People: └|∵┌| |┐∵|┘

  • More like a skating ring filled with drunk toddlers Edit: after I made this I noticed somebody else commented the same thing so the reply section doesn't need to be a warzone

  • what's stopping the Caplan thruster from turning the solar system to a sinder?

  • How could you build the mirror you would run out of materials?

  • We take the solar system and PUSH it SOMEWHERE ELSE!


  • why cant we combine the both stellar engines ?

    • Because the shkadov thruster would get in the way of the dyson sphere/swarm

  • Sun is a deadly laser? Shoot it with deadly laser.

  • 12020 is a trap!!! Go back!!!

  • Hey AllahI know what we’re gonna do today

  • But if you only move the sun and not everything around it, won't everything on the side that it's moving towards fall into it?

  • Year “12019” ??

    • Kurzgesagt has a thing where they refer to the years as 12020 instead of 2020.

  • Science stupid Science stupid Science doesn't know. Positrons × and electrons -- rotate very rapidly after 46 billion years of creating the Hercules - Corona borealis Greatwall. So the core of the Hercules - Corona borealis Greatwall very quickly like A super large electric turbine that produces super large electrical energy Every second Hercules - Corona borealis Greatwall emits 2400 billion billion tons photons, move circle at light speed return to its original position after 93 billion years, so it pushed the entire universe to spin

  • NASA: take notes!! NASA: fuck yes!

  • Me, confused as to how big the Caplain thruster is:

  • I'm about to say something dumb but if the hydrogen jet keeps the balance of the thruster wouldn't the mean the jet is as powerful as the engine?

  • The fretful environment universally pump because hydrogen focally offend forenenst a idiotic volleyball. tangible, bustling jewel

  • We could build a stellar engine

  • Just chuckling at the fact that I, initially, thought this was just about a sun-powered spaceship... how you just going to move a whole solar system? 😅

  • "Nothing in the universe is static" But there's static all around, it's called electricity

  • 7:26 mew

  • Hold up! Did he say drunk toddlers?

  • yeah, but would this have any effects on us? like wouldnt we notice the "sudden" change in direction or speed?

    • @Em trish nah i mean moving the solar system, like we dont feal earths movement cause we got used to it, but what if we suddenly start moving the earth in a new direction?

    • I can imagine that by the time the helium reaches us it wont be dense enough to do harm and the magnetic field could block some of it off

  • sun verry dense not work

  • but how are we gonna build a giant mirror half our solar system

  • i dont know why but im dying because he said at the end 12019 instead 2019

  • We gaan andere sterren koloniseren

  • So you're assuming that the sun's surface is not gonna be penetrated by the forward thruster. I mean it's possible that all that energy beams inside to the other side, like a needle passing through a cloth. The engine would collapse then

    • The sun is extremely dense. I’m pretty sure these guys know what there talking about

  • Oop, guess it's time for an existential crisy

  • Anyone’s curious about the two other stellar engines?

  • We have a hard enough time doing anything about climate change while it's happening. I don't know if we're gonna be able to plan 100-1000,000 years in advance..

  • that message at the end aged poorly

  • but what if we encountered something more massive than our sun and our planet got attracted to it?

  • At the end he said let’s fix up earth Me living in 2021 👁👄👁

  • That mirror concept is confusing. How is it supposed to encourage the sun to move? The way it is shown here looks like the light particles and radiation will bounce off it and push the mirror and the sun away from each other.

  • Lol turn on the captions on the intro music

  • I love that there are 10 million people that think similar to me, let's spreed our knowledge and help raise the collective intelligence up and beyond

  • great

  • Him: everything follows the sun by gravity Me in universe sandbox: oh really?

  • Dream be like: 4:18

  • 7:26 mew

  • aliens: congrats on becoming a type 3 civilization humans: YOU still EXIST!?

  • This is one of my favorite videos!

  • This could make a great movie

  • These hypotheticals are a waste of time. We cannot build more materials than what is on Earth. We cannot build anything bigger than Earth. Now we talking about the Sun? No..

    • @Dee Nell "Theoretically, anything is possible" Are you even hearing what you are saying? This is like saying that a dog can be a cat if there is enough resources to do a thing. Any imagined theory is only plausible if there is ENOUGH research based data that can backup the points presented in the concept. 𝗔𝗻𝘆𝘁𝗵𝗶𝗻𝗴 less than that can be debunked by a 7 year old. Think before you write/speak.

    • @Dee Nell You don't have to insist yourself in believing that it is possible because it is a HYPOTHETICAL scenario. The video was only explaining what would happen if it indeed were to happen. Did the video said we have enough resources to do that? Was there any particulars that mankind care enough to do such actions? 𝗧𝗛𝗘 𝗔𝗡𝗦𝗪𝗘𝗥 𝗜𝗦 𝗡𝗢. So there's no point in bragging about your incapacitated borderline fantasy about "haVINg EnoUgH CApAbIliTies and ReSoURces" because you're sounding like a total high school drop out.

    • @Dee Nell Come back when you realize what a hypothesis means.

    • @Rin Bañares Something to understand.. Some things are possible but will never happen. Theoretically, anything is possible. Does man have the capabilities and the resources? Anything beyond Earth is a no. Millions of Earths fit into the Sun. The number of atoms required to move the Sun is more than the atoms on Earth. We cannot build something to move the sun. Now, if you wanna understand something that wont ever be done, go ahead smart guy..

    • @Rin Bañares You dont have to comprehend something that can never happen. It's a waste of time. And thanks for playing today's version of keyboard tough guy dumbass..

  • There will probably be a point where humans will live for hundreds of years, and so we will hopefully start thinking about the future more as they will be part of it.

  • Is it right to assume everything in solar system will move with the sun ? In the current stellar configuration, yes. But if we end up closer to some other star, can't it possibly pull out some planets from solar system due to its own gravity ?

  • 7:26 I just realized at the bottom right Is that a pokemon I think it's a pokemon

  • The ending to this video did not age well. Writing this from 12021.

  • 8:20, it's gonna get more screwed up don't you worry

  • caplan thruster: completed earth: finally! here we g- the huge exhaust fumes in the illustration: bonjuor

  • Because of you i got an A+ in my bio test Thanks

  • Meanwhile humans:

  • F 2021

  • the animation CUTEEEEE OMG

  • Yeah that fix thing didn’t really work
