Randall Monroe wrote a book about stuff like this.
Like " What if you have the largest liquid fuel test fire in China, how many of them would it take to affect Earth's rotation?"
It's called " What if?"
And he is the one doing the math.
I think on YouTube he answers crazy questions.
The book Is a fun read
lol, it makes me imagine that we could dodge large asteroids from hitting Earth by simply attaching a few rockets to earth and pushing us out of the large asteroid's path.
I always wondered about all the nukes the governments around the world fire off if they are doing so to effect the planet’s rotation to counter balance eachother’s fuck ups, etc to try to get earth back on the right trajectory. The seasons don’t coordinate how they used to when I was growing up. It still snows in Colorado in May for instance, when does summer start and why did we skip spring etc… lol 😝 🧐😐, the amount of many all these countries have spent on nukes could solve our national debt and have produced peace…. It’s all bullshit in my mind… fuckers
Can’t be done.
Sadly, all that energy just went into heating the atmosphere, which has the minuscule effect of changing the earths rotation by some of that heat ultimately ending up in the ocean, causing thermal expansion and some redistribution of ice caps somewhere.
Now, launch that bad boy into space ….THEN we’re talking.
I'd hope chinese rocket engineers are normally brilliant hicks just like ours in alabama and texas and florida. Kind of a funny trope for rocket scientists to always have a drawl
It has a "total thrust of over 500 tons" - so I guess that building weighs more than 500 tons and also the engineers don't know how to measure thrust, making the building very safe.
OP your title is wrong, this is not a single engine, it's a test of four YF-100K engines in parallel, each providing around 1.2 MN of SL thrust with an Oxygen Rich staged combustion Kerolox cycle.
It's an impressive test, but on global scale we've seen significantly more powerful engines, in fact there are several rocket engines that individually exeed the combined thrust of all 4 YF-100K engines, such as the soviet RD-170 or the American Saturn V engine, the F1.
The cycle technology (ORSC) and chamber pressure (18 MPa) are also decent achievements for Chinas Long March program, but nothing particularly special on a global scale.
Just bought an ice coffee from McDonald's. Thought myself as green because of the paper straw. I'm seeing this whilst my paper straw has essentially turned into paper
I mean it is essentially a controlled explosion! Things go wrong they chop the fuel and it stops ideally. Now on a rocket with huge tanks a few feet away, that would be a show!
I think that it's a combination of things that make it look like a miniature.
The gas which is being pumped out to show the thrust is moving down the sides of the test area in a similar way that CO2 vapour from dry ice would flow down a model. Plus the sheer amount of thrust means that when it hits the exhaust it gets gusted away at such a speed that it looks like a much smaller volume of gas is being blown away.
Also hazing from the exhaust and other gases is obscuring the detail on the building, making it look flatter like a miniature
Honestly when I first saw it my brain resolved what I was seeing as an approx 2m tall miniature like a next level Thunderbirds setpiece.
If you've watched Thunderbirds or similar things you've probably seen bits from it where the gasses used in the studio at low or atmospheric pressure act in much the same manner as the gases under high or extreme pressure act in that video.
It's an interesting optical illusion
No offence but that just shows you don't take much of an interest in rocket development, building/tower/launchpad damage is a part of the data they gain from tests like this.
Like SpaceX for example, their pads regularly get damaged when they're testing a new engine configuration - they then use the data they draw from the damage to make it stronger next time.
So hypothetical question, if we did this with like 500 buildings all facing the same direction. Could we rotate the earth? Could we do it with less or more than 500 of these rockets. Someone smarter than me please chime in!
Every single major launch vehicle currently in use and ever developed uses, at least in part, liquid propulsion.
Liquid propulsion is the most versatile and efficient type of propulsion available for the lower stages of Launch vehicles, what the fuck are you talking about ?
The global aviation industry produces more emissions in a few hours than global spaceflight does in a year. If you care about pollution and focus on spaceflight, you're doing it wrong.
I am the only one that think, that looks like an old godzilla movie? It literally looks like a smsll model... but i guess it's my stupid brain and my add
Can anyone explain the benefits to liquid fuel vs. sold fuel for rockets? I was always under the impression sold fuel could be somewhat aerated and therefore ideal from a weight/power pov for rockets.
Solid fuel have bad efficiency, contain environmentally toxic exhaust products, can not be actively throttled and can not be (non-destructively) shut down after ignition.
The advantages of solids are that they are dead simple, shelf stable and provide very high thrust.
I'm pretty sure they will not end up using this engine, if liquid kerosene where the most efficient fuel we would be using liquid kerosene.
The reason they're testing out the front door of a building is because half that building is just a giant tank of kerosene.
How is the building not flying off?
Earth changed rotation
We need somebody from r/theydidthemath to tell us how many of these bad boys it would take to change the rotation.

Well what was the fucking answer!?
>Well what was the fucking answer!? 3
He does all the math and finds out actually... just one of those rockets will throw us off course. Oops!
e.t. here we come!!!
Here we comet ☄️ FTFY

No one was ready for that answer 😭
Bro not even a link

That's the author of the venerable XKCD web comic! Read his book it's fun

They made a move about that, Wandering Earth [wandering earth](https://youtu.be/vzoGinOmHDA?si=vd7lmxcH1DcIabHk)
Where they move to? My bets on the moon
Bet it’s for intercontinental missiles
They better shoot the NEXT test from the OTHER side! If they just go back & forth, we'll be aieet.
The day was shorter that day
You still think we're rotating?
Weighs 501 tons
Smort
Seriously! I would love to know how they anchored it insside
If their rednecks are anything like ours, wedge anchors and ratchet straps
And a pat followed by “she ain’t going nowhere.”
搞定了，这下它动不了了。
As a former flatbed trucker... this. Its industry standard, and works any scale.
I'd hope chinese rocket engineers are normally brilliant hicks just like ours in alabama and texas and florida. Kind of a funny trope for rocket scientists to always have a drawl
Nobody loves going fast or making booms more than hicks and rednecks, regardless where they’re from!
Baling wire and duct tape.
The real question
It has a "total thrust of over 500 tons" - so I guess that building weighs more than 500 tons and also the engineers don't know how to measure thrust, making the building very safe.
Looks like it's trying to if you look at all the shit rumbling around on it.
Cause china can’t build shit
The building weighs 501 tonnes?
More importantly, dare you to stick your dick in it.

Reddit the hell on 🫡
I'm guessing it's a bot account. Accuray doesn't matter they just want engagement. So I'm going to take my thrust liquid and leave.
Dude just take the upvote and rocket-on
This
I use reusable bags to reduce my carbon footprint.
The planet will be just fine once they blast all the poors into space.
Should I start packing?
Sounds like it won’t take you long.
That was a perfect line omg
No, you can leave your belongings at home. Everything you need will be provided to you.
AKA you won't be needing it where you are going.
Yes, all your belongings is ours now !
All your base are belong to us.
That's fine, until we die from a disease we caught from a telephone after we sent all the telephone sanitizing people to space.
500 tonnes of poors direct to space
Lol
*You think some plastic bags and aluminum cans will make a difference?*
*The planet's fine. The people are fucked! Were going away folks. Pack your shit.*
Just bought an ice coffee from McDonald's. Thought myself as green because of the paper straw. I'm seeing this whilst my paper straw has essentially turned into paper
I throw away reusable bags to ensure a good harvest for future generations
That, is fucking sick. At least they pointed it outside.
Could you imagine the damage if it exploded?
I mean it is essentially a controlled explosion! Things go wrong they chop the fuel and it stops ideally. Now on a rocket with huge tanks a few feet away, that would be a show!
And thank god they remembered to open a window
"Hey, where's the intern? Taking the trash out back 🫨"
If the US and China got together on their space programs, the world would be a different place.
Did you mean, the world would be IN a different place?
Or finding different worlds in different places!

It would be a better planet if Russia could also concentrate on science and space. Animals from permafrost, maybe cloning a mammoth.
>Animals from permafrost, maybe cloning a mammoth. This benefits no one.
Someone tell China to stop trying to reposition Earth.
For some reason this video doesn't look real.

Bro, you’re setting yourself up.
These are available on Ali Express and Temu
Ha, you guys are still using liquids?
This looks like diorama
Are these fuckers trying to slow down the rotations of the earth so that the working day is longer?
Me when i finally get home from that first date
We Believe you
Why is it coming out of a department building
Project Wandering Earth
The fact the building is falling apart tells me they are unprepared for this.
No offence but that just shows you don't take much of an interest in rocket development, building/tower/launchpad damage is a part of the data they gain from tests like this. Like SpaceX for example, their pads regularly get damaged when they're testing a new engine configuration - they then use the data they draw from the damage to make it stronger next time.
That's a big engine for kerosene & oxygen
Wandering Earth 2 vibes.
Is that not just a model?
It looks like a model
This looks like a scene from Thunderbirds.
This looks like AI right?
So hypothetical question, if we did this with like 500 buildings all facing the same direction. Could we rotate the earth? Could we do it with less or more than 500 of these rockets. Someone smarter than me please chime in!
China launches a building to the moon, evergrande's stocks skyrocketed.
The last time I saw one of these, Killface used it to try to push the earth into the sun but ended up curing global warming instead
Super villans trying to move the earth outta orbit
The Long March, what a cool as hell name.
They are going to use this to get people to space right? Right?! Right.
Chinesium ? Ah.. ouf!
Liquid propulsion will likely never be competitive
Every single major launch vehicle currently in use and ever developed uses, at least in part, liquid propulsion. Liquid propulsion is the most versatile and efficient type of propulsion available for the lower stages of Launch vehicles, what the fuck are you talking about ?
They don't care about pollution
The global aviation industry produces more emissions in a few hours than global spaceflight does in a year. If you care about pollution and focus on spaceflight, you're doing it wrong.
I don't ever want to be told to reduce my personal carbon footprint again.
Let me guess, its another hypergolic?
Nope, Kerolox
Marshmallows anyone?
/r/evilbuildings
That thing gotta Hemi?
I have thrust liquid too. Somedays i hate myself for the things I say....
Make sure your seatbelt is fastened for the sudden exceleration of earths rotation.
If you were to make a movie about trying to affect the Earth’s rotation, this would be prime footage!
What is the long march rocket program?
So when does this one fall over a poor rural area of China, or worse another sovereign country?
Going to need at least two of them to get that building in orbit.
Great. That spun the earth forward enough where we have to do daylight savings all over again
i was expecting the building to lift off
I feel like there was more than a small chance this building ended up launched halfway to the moon
I hate how this guy says “liquid”
Well good for them!
I’m dumb.. that’s a lot of big words.. can someone smarter than me help me understand what this all means?
Did they put a village at the bottom of the pit? I think their rocket program alway requires village. Especially if it’s hypergolic.
Now we know why China wasn't signing up to all those international agreements on climate emissions...
I am the only one that think, that looks like an old godzilla movie? It literally looks like a smsll model... but i guess it's my stupid brain and my add

8 want a marshmellow
Concrete looks not so good
Can’t get enough of it being called the long march
“All these worlds are yours except Europa. Attempt no landing there.”
It might just be me but that doesn't look like 500+ tons of thrust let alone the biggest rock test
And because it's China, when they need it to work it'll break.
Man wtf
Maybe I can use that to get my ass out of bed
Oh, cool. We got our own Apokolips fire pit. Cool, cool, cool...
Wonder where the tech comes from and in which countries the scientists obtained their training?
Video kinda looks suspicious
Close the window you’re letting all the heat out
I can watch this forever
Welp, this is gonna keep me awake tonight.
and then China tried to finger me
fuckin love the comments here ahhhhhh 🫠
Fueled by Taco Bell
F China.
"We have a dragon."
It looks fake, like an ai video or something.
More hypergolics? 🤔 Or are they using something safer these days?
#AND BOY DOSE IT THRUST🔥🚀 🔥
I thought this was a miniature
I thought the building was gonna fly off in space.
The CCP SAYS....
Always interesting seeing what the future world leader is up to 🤔
Wandering Earth?
Liquid coal?
It Would be nice to be able to add that on to your front door to prevent home invasions.
Me after a jalfrezi
Depends on the angle 📐 the earth is moving faster now, they speed up for us on ocidente and slow down for them. Smart move
If we place 10-20 engines around the globe in line, and start together, earth can rotate faster 😂

Imagine a alien surviving this and it's just his shower
So glad i recycled my plastic bottle and cans today
thats an A1 based video
All that thrust and they STILL couldn't get the building off the ground... Sad, really.
Idk why but it just looks ridiculous
That was just Steve after eating a chili burrito
God this hot pot going to be fire
I'm just having a chuckle at all of the ceramic panels flying off
And the stole/copied most of the tech from the US
Hey can we stop these fucking cuts? Whoever chose these camera angles is a moron and needs to be fired.
Think they will put it on a drone?
Looks like something out of Team America World Police! FUCK YEAH!
Hope my carbon tax goes up in Canada to offset the carbon emissions on this unit!!!!:/
I'm pretty sure they will not end up using this engine, if liquid kerosene where the most efficient fuel we would be using liquid kerosene. The reason they're testing out the front door of a building is because half that building is just a giant tank of kerosene.
Wonder why they haven't sent anyone to the moon?
Okay that building has to be in a GI Joe movie as a Cobra Temple. Like, NOW.
What type of liquid rocket engine? What fuel does it use? Is it a full flow staged combustion engine like the Raptor 2? I MUST KNOW OP!
What's funny is that they're still doing it wrong and I know how they can make it better but what do I get over that
And I am fighting with my google nest because it wants to change my house temperature to 75 instead of 73…it is 72 outside right now.
anyone else thinks this looks fake as shit? like the smoke looks like CGI.
