For over 680 days I have not had a functioning Vagus nerve nor had the ability to sleep naturally at all. I've seen multiple neurologists, specialists, psychiatrists, therapist, and even been part of clinical trials and nobody understands how my body is operating this warped state.

I've had extensive testing from autoimmunity, neurology, cardiology, and any potential cause, and nothing can be sourced as to why my body is stuck in this way. I'm inexplicably immune to benzos and even allopregnanolone, the very neurosteroid responsible for maintaining inhibition in the brain.

The only thing my team of doctors knows for sure is that I lack basic inhibitiory tone in my brain which keeps me from ever sleeping naturally, even microsleep confirmed by a polysomgraphy. I've gone 9 days without sleep before finally getting a sedative that works, a copious amount of seroquel to just smother the brain unconscious every night for the last 680+ days.

Due to not having a functioning vagus nerve, basic human functions don't work on me including my VLPO to engage sleep. I never feel tired, sleepy, or comfortable ever. I get no rebound from exertion, so even just going for a light jog can leave me exhausted with a resting heart rate in the 180s for almost an hour as I get no acetylcholine to balance my body. I'm forced to be sedentary against my will due to not having parasympathetic rebound capacity. I have no hunger at all as no ghelin is ever made so I have to force myself to eat every meal. I essentially have a denervated heart as my resting heart rate is 115 and didn't shift at all during a stellate ganglion block. My heart rate variability has been 5-28ms this entire time and has never improved from anything.

And what is the strangest of all is this was all just brought on by a stress episode. My wife had a traumatic birth and I was overthinking and ruminating about the health of her and my son and I just got into this state from that stress episode and haven't been able to recover from it even though that event is no longer a threat and I've worked through it from multiple therapy modalities that I don't even feel anything for it anymore. No virus, no physical damage, no autoimmune source, and all of my labs outside of my neurology and cardiology downstream of the vagus nerve are 100% healthy and clear. Also my condition isn't degenerative at all. No loss of cognition, memory, motor fuction, or even any brain fog. So everything is working normal except my brain refuses to allow me to ever enter a parasympathetic state again.

We have tired every mechanism in modern science that can lower the sympathetic nervous system and increase the parasympathetic nervous system and nothing has even budged my stuck state. (I'll put a list of all the things I've tired with my medical professionals in the comments)

At this point, after trying everything in modern medicine, my neurologists have essentially told me my zebra case is beyond medical science and they don't know anything else that can help something that isn't operating within what is the current understanding of neurobiology.

Can a case like mine find the right people through Kurzgesagt?

oh holy shit he wasn't kidding

As someone that sadly uses twitter whenever I search up kurzgesagt all I see is posts hating them saying they do false optimism that they are slop that they are ai and other similar posts

It’s giving me major whiplash from seeing how they are talked about on yt so I wanted to ask why twt hates kurzgesagt so bloody much

Went to check their Socialblade because their recent video's are doing so incredibly well. Views for other animation/explainer channels like TED-ed have also doubled.

Seems like Youtube's recent policy change to favor original content over purely AI generated / curated stuff is working quite well?

Really confused here unless I've missed something obvious.

The space video artbook is shorter and lighter than the Human Era Calendar artbook. The Calendar artbook is easily the heaviest artbook I own.

The concept of terraforming Venus and Mars by a Type II civilization.

The essence of the idea: Instead of terraforming Venus and Mars separately (trying to combat their fatal flaws), a Type II civilization would combine them into a compact binary planet system in Mars’ orbit. In this union, the geophysical drawbacks of one planet would be offset by the advantages of the other, triggering a self‑regulating natural mechanism.

STAGE 1: Migration and the Creation of a Double Planet

1. Orbital shift: Venus moves into a Martian orbit. The influx of solar heat drops by 2.3 times, which triggers a natural and rapid cooling of the planet.

2. Orbital lock: Mars is placed into a circular orbit around Venus at a close distance - about 120,000 km (3 times closer than the Moon is to Earth). The orbit of the entire system around the Sun evens out to a perfectly circular one.

STAGE 2: Mutual “revitalization” of the cores and the initiation of the dynamo

1) Acceleration of Venus: During the approach, Venus is forcibly spun up. The immense gravity of nearby Mars begins to drive a powerful tidal wave along its equator, acting as an “external mixer” for Venus’s liquid iron core. This triggers the formation of a powerful magnetic field.

2) Mars’s “wobble” (the Io effect): under the influence of Venus’s gravity, Mars slows down its rotation to match the orbital period of the system (3-5 days) and enters tidal locking. However, due to gravitational perturbations in the three‑body system (the third body is the future icy satellite “Harmony”) its orbit retains a micro‑eccentricity. Venus continuously “compresses and expands” Mars (tidal flexing), completely melting its solidified core and generating Mars’s magnetic field.

3) The magnetic fields of the planets merge into a single super‑magnetosphere at such a distance. This giant magnetic cocoon reliably protects both worlds from solar radiation and the stripping away of their atmospheres.

STAGE 3: The Birth of the Satellite “Harmony” (Concordia)

To reduce the hellish pressure on Venus (93 atmospheres), engineers shield Venus from the sun so that the entire atmosphere freezes into ice, and they send the ice made from excess carbon dioxide and nitrogen into orbit.

1. Ice core: This ice is compressed in orbit into a super‑dense ice core with a diameter of about 700 km.

2. Stone shell (Thermos): The moons Phobos and Deimos are ground into rubble. This regolith (with the addition of asteroids from the Main Belt) covers the icy satellite with a thick layer. This creates an ideal thermal insulation storage space, protected from sublimation by the Sun..

3. Gravitational tuning fork: the satellite is called Harmony (in mythology, the daughter of Venus and Mars). Due to its mass and orbital resonance, Harmony prevents the orbits of the planets from becoming perfectly circular, ensuring that the gravitational excitation of their cores and the operation of their magnetic fields will not cease..

Result:

We are presented with a unique, self‑sufficient triumph of engineering thought:

1) Venus becomes an oceanic world with a comfortable climate. In its sky, a living, green Mars hovers stationary - it is six times larger than our Moon.

2) For Mars, Venus becomes a colossal azure shield, shining 12 times brighter than the Moon and turning Martian nights into gentle dusk.

3) Between them, the pearl‑moon Harmony circulates - a perpetual raw‑material depot and orbital port of the system.

The internet will one day rule over us.

Kurzgesagt is complaining about AI non-stop, why not just use AI?

Other people are using AI and getting success for their AI youtube channel, if kurzgesagt doesn't adapt they'll just fall behind. It's an adapt or be eaten world...

Is there any likely release date for the third limited edition pin? I came to the party late and this is the first set that have released since I subscribed, and if there's a release schedule it'd be good to know.

Also, any speculation on what it might be? With a spinner and a lenticular pin in the set, I'm thinking maybe something that has a UV or glow in the dark design would match the theme.

Hey Kurzgesagt team and community!

I have a video suggestion that feels like the ultimate existential Kurzgesagt topic: The KBC Void and MOND (Modified Newtonian Dynamics).

Recent astrophysical discussions have highlighted a mind-blowing theory: our Milky Way (along with Earth and the Moon) might be sitting right near the center of a massive, 2-billion-light-year-wide cosmic bubble with 20% less matter than the rest of the universe.

This isn't just a cool fact about our cosmic address; it could completely shatter our understanding of physics:

• It offers a wild solution to the Hubble Tension (why the universe seems to expand at different speeds depending on where we look).

• Standard cosmology says a bubble this big shouldn't even exist.

• To explain it, some scientists argue we need MOND, which claims gravity works differently on a cosmic scale than Einstein predicted.

Imagine the animations! A giant cosmic void, the illusion of a faster expanding universe, and a fundamental challenge to Einstein’s theory of relativity. It has the perfect mix of existential dread, beautiful space visuals, and cutting-edge science.

What do you guys think? Would you watch a video about us living in a cosmic desert?

For ai safety

Say for example an ai agent is suspected of being mischievous or cheating on saftey tests.
We would want to shut that agent off.
But we don’t want to risk accidentally shutting off a good ai agent.
Which is where my idea comes in.
Invent a test that’s impossible to complete following every rule correctly
Ai agents that fail the test is likely clean.
Ai agents that pass the test however have cheated to pass it.
Run these tests on the same ai agents many times and you can note accurately determine which ai is mischievous and dangerous

Video Description:
For centuries, people have wondered about the strange sounds coming deep from the mountains of Kazakhstan. The singing sand dunes have sparked the imagination and countless stories about what might be the true source of these humming melodies, from trapped evil spirits to the restless soul of Genghis Khan.

What is hiding beneath the singing sands? How did Genghis Khan become connected to this phenomenon, and can science explain a mystery that inspired stories for generations?

Two videos on the Nightshift channel are member exclusive, I never thought I'd see the day I'd have to directly pay for kurzgesagt content smh.

what if you have a theoretical time machine that can open up a portal from year 12026 (i use actual human years here, means its year 2026) to year 0, pull several first human people, a baby, a child, and a young teen, and bring them back to year 12026, can they function as a modern day human with enough time to teach them?

Hi , im new to Kurzgesagt channel and i watched the latest ai video which was pretty unsettling and i loved it.

And i want more unsettling videos like this, it could be about anything and not just ai.

And i also got creeped out by the egg video i dont understand why people find it so calm and relaxing It would be a eternal nightmare to think you have to go through all lives on human history.

So i would like to see more videos like this.

First time making something like this... any feedback is appreciated!

P.S. it will ask for ChatGPT or Instagram, plus location to personalize the experience (I'm not selling your data I promise)

Enjoy :)

Btw, you'd probably be interested in reading the book MIRI put out last year if you liked the HF video: Context here.

Matabele ants and their feeding behaviours. Termite lifestyle sprinkled in would be a nice touch.
