Getting to space is incredibly hard, expensive and needs a lot of resources.
A more efficient way to get there is a Skyhook (or Spacetether), an ever rotating cable with a counter weight, that catapults spaceships from earth orbit into the depths of space.

So in 11038AD we'll be shooting people as projectiles from giant gun barrels?
@@HerrRussoTragik why not a railgun using megnets?
Considering the string would fling humans, which are basically animals, and asteroids are basically rocks, you could exploit that technicality and say: 7000BC: Rock and a string, the ultimate ranged weapon for hunting animals.

Imagine Kurzgesagt develops a space colonization game with all of these elements they've discussed! And this art style would only make it better!
I would pay a lot of money to play that game!
thats literally my dream
Extremely underrated comment
I wish but like, they're too busy making high quality videos for us, what with managing merch too, if they somehow make the game tho I'd absolutely love it
I think someone said this in the comments of their stain sphere video
this is cool and all but just imagine the horror you'd feel missing the tether on your return trip to earth or Mars
I guess you'd still need rocket propulsion as a failsafe. You wouldn't have rockets on the vehicles themselves because the whole point is to phase out rockets, but could rescue vehicles be stationed in orbit to catch anyone that got away?
The tethers fling you much much faster than a normal rocket flies. The amount of fuel required to do a recovery would be more fuel than we have on earth, most likely, as not only would you have to catch up to them (ie you'd need to be flying faster), you'd need to also be able to invert your direction of travel and then slow down again when returning to the planet. Even then, would both crafts have enough oxygen to survive the amount of time it'd take to recover? I'm sure the recovery craft would, but I doubt the "lost" craft would.
Unfortunately this entire idea is probably unfeasable due to this. The risk of missing a tether would be too great, basically a guaranteed loss.
@@fatboychummy bro, we literally already have aircraft that can go that high, and also getting an aircraft to go 12 k kmh rather than 40 or 50 k kmh. If we want an early and efficient space travel machine, this is it.
@@fatboychummy and the cost efficiency would easily overide any lost aircraft, and plus if we actually coordinated the launches, less aircraft would be loose, like airplanes. Finally even this method is till a lot safer than going 40k and crossing your fingers you don't randomly blow up
@@skootties the ships themselves still need rockets to get up to the tethers, so you could have extra fuel in those for course corrections, using a nav computer to calculate the necessary corrections,
Now: a Phobos skyhook will keep speed forever
2819: Phobos velocity crisis
more like 12819
as of that point, I'm sure we will have enough resources to speed it up.

@@IIIRobIII BIG SPACE YEET STICK!
Best reason to have high atmospheric refueling is getting a station on the moon. We need an industrial infrastructure to build orbital platforms. I wish we invested in a rail lift platform. The US has a perfect launching region that most of the world lacks. The desert of the southwest US is ideal for it.
Use fuel as the tether weight, refuel as you get flung!
There is one component here (That I can see) that would make this incredibly more difficult than it appears to be.
In their video, Kurzgesagt noted that the tether would (at its lowest point) be at 80-100km going mach 12. For context, the fastest air breathing jet ever built is widely considered to be the SR71 Blackbird, which could climb to an altitude of roughly 85,000 feet (26km) and sustain a speed of mach 3.14. Constructing an aircraft that can fly at about 4 times faster and higher than this while carrying a substantial amount of passengers/cargo would be insanely difficult.
I know Kurzgesagt addressed this in their video too when they said; ""We will need specialized spacecraft to get to the tether, while this isn't exactly easy [its better than rockets]." I just felt like this specific challenge could be covered a bit more in depth.
I still agree with Kurzgesagt that this concept is way better than rockets however, also this was just my 2 cents. I am no aeronautical engineer and if I got anything wrong here then I am open to constructive criticism because I am like everyone else here in that I think it would be cool to learn something new today.
To be fair, the aircraft doesn't have to be going that fast. It just has to rendezvous with something going that fast. Coordinating and surviving that much acceleration would be hard, but easier than flying to that speed.
@@lukesenseney1045 Yeah, what seems like an important point to me is the amount of G-force that would be experienced by ship travelers as they use this method. Seems like it would be very intense.
this is probably one of the most fascinating concepts i've ever heard. a concept so simple that its crazy we haven't started working on it yet.
that's why: the idea is still very unfinished and not currently possible, and lmao imagine if US government cared about anything expect of their military. And we also have enough problems on earth.
@@underpussy_ The US government and their military is the reason you have access to all this information.
But making is 1000km long tether looks impossible right now

The smartphone you're using right now exist thanks to technologies that we invented to reach the Space.

@@teopalafoxAnd all that information was found in pursuit of what? Weapons of mass destruction, that's what. US and it's Military are too dangerous to be let out on Mars, they might find enough Radioactive Elements to blow up the entire planet "on accident". Nope, not kidding. Look up the devil's core. That's Americans for the world. "Accidentally" killed many of their own people, not once, but twice. For what? The "freedom" to want to use a screwdriver to separate objects that would otherwise necessitate insanely more secure solutions to keep apart. No thanks, keep em away from Mars.

I can't imagine all the brain-melting calculations and problem solving you would need to be able to catch rockets with one spinning tether orbiting a moving planet or moon to another spinning tether orbiting another moving planet or moon 💀
thats why funding stem is important. astonomy, engineering, and math. plug those into a computer and it now is possible
@@Triobian true, but sadly the government probably wouldnt pour billions to make this idea into a reality anytime soon...
IKR
The physics & maths involved would be soooooooooooo high level and we have to fool proof it
In the end, it's just about the calculation, it needs to be very precise and very reliable. I'd say we've got technology for it, just another C program running with enough computation power. What I'd worry about tho is the dread when on one day, you get production bug, meaning there is a rocket which missed it's sling and is now on its way to exit solar system. That's gonna cause some headaches..
Honestly, I don't think it's all that complicated. You know how much momentum the skyhook transfers when it yeets a payload, because you designed it. You know the mass of the payload, because you approved it. Using those, you can calculate the velocity that the skyhook will accelerate a given payload to.
At this point, it becomes the same as flying a conventional rocket to another celestial body. You can precisely calculate arrival time because the orbits of those celestial bodies don't change. Yes, you're aiming for a moving target from a moving platform, but you know precisely where both you and the target are going to be at any given moment.
Once the payload is at it's destination, you just do the same thing in reverse. You know how much momentum you need to arrest, you know the capabilities of your skyhook. It's basically just a matter of not accidentally over or underspinning the skyhook, which is basically down to good planning and emergency engines.
I'm 14 and I'm really hoping I can see this kind of stuff happen one day!

Do you have sny idea how many rps this tether would have to be spinning while sustaining orbital speed in order to become a viable choice of propulsion? Lol
@@joweydelanota5558 so what are you gonna do make a bunch of expensive reuseable nuclear fueled rocket like elon musk plan? If you want to do that you must use an energy source that is unlimited. Lets say we will need the dysons sphere first before we can do that
@@joweydelanota5558 I mean, do you? Have you done the math? Anyone with basic physics knowledge knows that it is clearly not about the RPS but about the length of the 'arm'. If the hook is long enough, even a really low RPS is enough for meaningful propulsion. Torque is a relation between the length of the arm, the force applied and the sin between the force direction and the radius direction. We are talking about a ~1000km cable with an asymmetrical weight. Also, since we are talking about space, the final velocity achieved by the hook is kept by the vehicle. Since the vehicle mass is way lower than the hook's mass, the energy transferred to the ship is significant.

something tells me that Ice Cube’s form of revenge is sabotaging the space tether.
That would be the worst terrorist in human history
In the future:
"OMG mom, I will be late for Christmas, I friggin' missed the space hook"

Aldrich Luna I don’t think Religion (like Christmas is about) will exist much in interplanetary future.
People will finally abandon that fairy tale since science will always win
@@ShawnLH88 I don't really think Christmas is about religion anymore. It has become tradition and is more about being with family and such values

@@andersenzheng nice.
Well, someone once told me that spinning was a good trick.
Fantastic idea that we should implement as fast as possible.
Plan for space travel:
1: get to the moon.
2: build skyhook
3: use the moon to get to mars
4: build skyhook on mars
5: use sky hook on mars to get to mercury and Venus
6: make skyhooks on mercury and Venus
7: gather lots of Venus solar energy
8: use solar energy to build railgun on mercury and robots
9: make Dyson sphere on sun
10: profit
Our plan for space travel is getting to the moon then build skyhook on there then use the hook to get to mars then make a skyhook then use it to get to mercury and venus then make solar panels to make railgun and make a dyson swarm to get energy.

Good luck making sense of the replies
It’s a cool spinning rope
Fidget spinner = infinite momentum
We haven't met any aliens, maybe they use more advanced spinning ropes, larger, spinnier
We're environmentally friendly, compared to the aliens... 0 CO2 or whatever will pollute the universe in the future...

Every time I watch one of these videos I grow evermore determined to become an Aerospace Engineer. I think if I can work for NASA and help bring us just one step closer to our future in the stars, I’ll have done what I was spawned on this space rock to do

CompletelyNewguy Humans are awesome.
Sometimes you can do amazing things with relatively simple concepts. Take guns for example, which are extremely good at killing. They're basically pipes that throw out pieces of lead propelled by an explosion.
@@Horny_Fruit_Flies the asgards are no longer capable of such simple concepts
@@Horny_Fruit_Flies Guns are just a pressure trapper.
You take a force that usually disperses out reducing it's energy into nothing.
Then trap that force behind a bullet forcing it in a straight line.
GG ez.
Again, humans can be space orcs forever.

I love how this sounds more science fiction than just a really big elevator and yet is more reasonable to achieve
It’s like Roald Dahl but real
design is practically impossible anyways
@@user-bh6cz8kp4q What? Sky hooks are legit possible.
@@Yamyatos Okay so as possible or legit as you might think they are; the challenge of finding the proper balance in momentum, accounting for space debris, manufacturing materials that can handle all that wear without risk of breaking before replacement, not to mention it's really easy to plan this stuff on paper and say yeah that looks good.
I want you to go to nasa or elon and ask for funding for skyhook watch em laugh at you and sit you down and explain how maybe, maaaybe the initial idea was plausable right, but when it gets down to it at the very least you risk causing general instability within the solar systems respective orbits
The solar system as we know it has been altered just by the rockets we've flown to the moon, and the satellites and what have you that we've launched. (Yeah, it hasn't changed anything in any real noticable fashion; yet, but imagine human expansion especially once we're harvesting asteroids)
Now; look at something like the tether, short term, sure its not gonna do much, but if you dont balance that expenditure of energy and the sudden addition and large influx of mass being thrown around that grows over time, and in fact draws on the very planets and moons rotational velocities and momentum to accomplish this.
Not to mention this will affect small orbital bodies such as asteroids/meteors etc., carefully plotted out courses will be altered and will assuredly result in earth strikes that will need to be prevented. Let me guess, y'all gonna throw a nuke at it with a tether?
@@sdrawkcabmodnar Nobody is saying it's super easy, and all you just said is rather common knowledge concerning some / most space travel methods. However, while earth may not be the ideal place for it (not saying it's impossible) due to space debris, scientists write paper about the physical capabilities of these systems since the mid 20 century. So while you may not get funding for it until we solved a couple problems and concerns, if you say it's an idea without a future, you are disagreeing with the scientific consensus.
this is an brilliant idea since its so cheap and not too hard to construct.
Its been 2 years give this man a nobel prize and build these things!!

Even when a Kurzgesagt video ends with, "but it's impossible for now/we probably just haven't hit our extinction filter/heat death of the universe" type stuff I usually still walk away feeling relatively optimistic because there's always a chance... But then you throw sci-fi dreams of a Star Trek future at us and there's no real "but?!" I'm ready to take on the world today!
agreed
Yo, I didn't know you watched Kurzgesagt? Love your channel btw
The "but" this time is money and bringing an asteroid to act as counterweight. Ain't simple but not impossible
but if you time your swing a little incorrectly you fly off into the middle of nowhere and slowly die. There's the "but".
It's true, money and the accidental eternal vacuum of space are both 'buts.' BUT, both can immediately be overcome. Discovering/creating new elements or stopping some unknown extinction event are heavy buts. Heavy butts.
This is perfect!
I loved this idea 👍👍
The last words NASA heard from the rocket:
*“Go long”*
Lol!
The profile pic and name makes me think all u do is just comment. Lol
More like YEET
"Grover go long."
*_[Hah!]_*
NASA: we dont get enough money
Kurzgesagt: Let me introduce myself
And then the government sees they can spend less money and reduces funding even more.
NASA gets more money than you'd think. Their budget is higher than SpaceX, ESA, JAXA and others. They are just more inefficient.
@@MladenMijatov Umm.. SpaceX is a private company, while NASA is getting money from the US goverment :)
@@MladenMijatov nasa gets barely any money compared to u.s military
@@piingufps Spacex receives huge amounts of money as private contracts from nasa

There's also the problem of synchronizing the throwing and catching tether for each and every ship
NASA: every decade we will make a new space shuttle
Kurzgesagt: what about a ball and a rope?
Hey Boss space shuttle program was closed my guy
tether and ball torture
Space Shuttle program was stopped after Atlantis' final flight about 7 years ago. USA has relied on the Russian Soyuz spacecraft since then.
@@theexam7394 it's a joke m8
@@heyboss1684 the first part didn't seem like a joke, but I get the second part. Just wanted to inform you about the space shuttle program.

Then there will be those people: "I don't want a spinning ninja star 80km above my house"
Risk vs reward, there will always be more humans but cheap and easy access to space is another thing entirely.
Haha then you ask them if they ever heard of the ISS. Plus, if it entered the Earth’s atmosphere it would likely burn up before it hit.
Tbh they could maje it so that it does not pass over populated areas or at least areas where these types of pricks are non existant
But they let airlines fly over their house.
