New fear unlocked: puffy head bird legs

Time to invent that artificial gravity button on space ships!

First few seconds: 😄 “Then you remember that that’s also happening in their bodies…” ☹️

So enough time in space you will begin to look like a stereotypical alien.

I have hydrocephalus, essentially a water balloon head. I can tell you what the effects are: long-term memory problems, concentration and vision problems. If it gets bad enough, coma, and death.

At first I was really confused why fluid would go to our heads specifically, then I realized our bodies probably have stronger ways of moving things up than down to compensate for gravity. Makes more sense now

We often forget how much we evolved based on earth's gravity.

And that’s why they need a rotating station like in 2001

It's almost as if we were never meant to leave the planet

Thank you, now I don't want to go to space anymore.

It’s in principle possible to equip ISS with centrifuged interior spaces, or even redesign it from scratch to be spinning while in orbit to simulate “centrifugal gravity”.

I wonder if they get more acid reflux? The stomach acid is floating around, too!

I had an entire chapter in my Physiology exam about the effects of Zero Gravity. I don't know how many astronauts they expect I will have as patients, but it was likely there to make sure you understood all those topics in people on earth.

Imagine being born in space. I know they're already researching this topic, but the thought of that whole process from fertilized egg to baby happening under the influence of microgravity is kinda scary considering that some developmental processes seem to rely on gravity

there is a dysautonomic condition that struggles to use gravity to pump blood. i dated someone with POTS and he always said being an astronaut would be a genuine treatment of the symptom

NASA is nothing more than high altitude planes, green screens, dark pools and bad hair days.

That's what I loved about the series The Expanse. Not only do they not come up with some magical artificial gravity solution to avoid the problem but the issues with extended stays in zeroG (and growing up in zeroG) become a main plot point and drives the series.

Some people really don't understand how difficult living away from earth would be, it's crazy to think living on Mars is even remotely feasible.

I always wondered about this, anytime I saw an astronaut messing with liquids I was always thinking "Wait, wouldn't that happen to their insides to?

Yeah you can feel your organs in space 💀

They know how to combat this. Rotating habits but that's easier said than done.

I love that in the show "the expanse" They included this. People who were severely bleeding couldn't be helped because of lack of gravity. The show is incredible and in many ways more scientifically accurate than most space travel science fiction shows / movies.

My bones felt uncomfortable when you said "that's going on inside the astronaut as well"

Everything in space is trying to kill you; even things we don't know of.

Something interesting i learned from Frank De Winne Belgian esa astronaut is that he had impared vision from his 6 month mission on the ISS

I agree, I think we are close to finding solutions to create a spacer with rotational gravity.

When I was a kid my biggest dream was to be ab astronaut. At 6 years old I was diagnosed with a chronic migraine condition and by middle school I found out that due to microgravity I'd likely never be able to go into space. It was heartbreaking.

Its really cool that we can function in zero g for a year in the first place.

From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainty of steel. I aspired to the purity of the Blessed Machine. Your kind cling to your flesh, as though it will not decay and fail you. One day the crude biomass you call the temple will wither, and you will beg my kind to save you. But I am already saved, for the Machine is immortal…

Thats so dumb, just float upside down. Problem solved.

Therefore, we need Earth's gravity to stay healthy and alive.

Some kid: I don’t think I want to be a astronaut anymore

Why does it go to their head? Why not their arms or butt or abdomen? Also why would it be different at all? Our blood is in a closed system that's being pumped by the heart. I don't understand.

Puffynauts

The way the smile wipe off my face after you said that I NEVER THOUGHT OF THAT

That answers my question why astronauts have trouble walking after being in space for so long.

Could they spin like a centrifuge to get the liquid back down to their feet?

The stretched ventricles took yrs to recover, but this vid also says the effects tapered off after 6 months. Strictly the effects tapered off, but the underlying damage was still present?

My kids, even now they're in their 40s, still call the way their faces look as soon as they get out of bed, their zero g face because I explained, when they were really little, that people in bed & astronauts have the same puffy look because of the way fluid shifts when horizontal or "weightless".

Imagine being outside of Earth's atmosphere, looking down at the earth through a window of a space shuttle on a one year assignment. There's no changing your mind after a few days. When you're up there, you're up there.

Elon: LETS MOVE TO SPACE IM INVESTING ALL MY MONEY IN THE ROCKET BUT DID NO RESEARCH IN HUMAN BIOLOGICAL CAPABILITIES Reality:

If an Astronaut stayed for an extended duration in space, they would return to Earth undistinguishable from Extraterrestrials. 😮

Space can be scary man that’s not the only stuff out there, that’s not the danger factor out there either

Please pin, or say it yourself. For phone users: save this short to a playlist (like "Watch Later") and watch it from there, and ALL links will then work!

Seems like this space thing isn't meant for humans

I didn’t know Daniel Tosh was this smart.

The person who came up with that name deserves a raise 😂

Good thing Im not planning to go into space for the next 1000 years :3 Earth is my favorite playground

I'm legit curious if this is an evolutionary based problem or a lifestyle based problem. Or to put it another way, does this happen simply because astronauts bodies are used to living with gravity, or if someone was born and lived their life in zero-gravity would they have the safe conditions?

When I clicked a short with that thumbnail, this was not what I was expecting.

Oh that’s why they always look like they are straining their face muscles/look like they have been hanging upside down for a while

Artificial gravity is gonna be a godsend once we figure it out

The Bird with human eyes and mouth is majestic

Never thought my CHD would keep me out of space, good to know that’s probably a big no go for me. Thanks for the knowledge.

That is why you do everything upside down. if fluid goes up, the going upside down means fluid stays in place

Man wasn’t built to be in space for extended periods

using rotation to induce gravity seems like the correct option to me

How would a period even work in zero gravity???

Love the iconic woman loaded with hairspray. Can't go to space without it!

My eyes feel like their pressure went up and I got a stuffy nose just from listening to this lol

Now that I think about it that's probably why aliens are always depicted with having big heads and thin bodies in films and images.

I love astronauts but I love them even more now to go through that just for the progression of space exploration

People who wanted to be astronauts: “ight im out”

There is also space blindness which is reversable in most cases. This is what I find the most scary.

Maybe that's why the typical description of an alien is a large head, thin arms and legs.

It almost looks like the astronauts have been hung upside down.

That's actually terrifying to think about. 😳

Need to develop a centrifugal simulated gravity for longer trips.

"Scotty, turn the gravity back on!"

This is why that Stephen King short story The Jaunt seems so real to me.

Could be solved with artificial gravity using centrifical force? Though we'd of course have to find a way to make those and spin them at the right speed.

That's why key for longer voyage is artifical gravity.

Sounds like a new evolutionary force given enough time

So this is how we have the classic big head and small limb aliens.

Puffy head + bird legs… so if we stay up there long enough we would become Aliens

Prob my favorite concept to tackle this problem is the “1G” ship. I don’t remember if it’s from a show or not, I only remember someone else bringing it up. But basically you have a ship that can accelerate at exactly 1G for half the distance (say, to Mars) then decelerate at the same Gforce of Mars. That way not only will your body not suffer the effects of microgravity, as well as becoming accustomed to lower gravity of the destination, but it will also help with centripetal effects that aren’t really mentioned when talking about centrifugal ships. It also would mean much faster travel, that is if we can figure out a means of propulsion that can do that.

Why is Ryan Reynolds lecturing me on space

Dint think the way along the line you presented facts. Awesome info and thanks for sharing.

Maybe it's a good choice that companies are working on artificial gravity

So wierd how their hair just is straight up all the time. 😅 You would expect it to be flowing around.

I personally love how The Expanse deals with artificial gravity by doing what they call the “turn and burn” maneuver. Basically they accelerate hard to get going at a few Gs, and then they hit “cruising speed” at an acceleration of roughly 1G and the ships are all built like skyscrapers where the floors are vertical. The ship is essentially flying upwards which pushes the “floor” against your feet at 1G so you feel relatively normal gravity. And then when they reach the halfway point (or somewhere around there) they “turn and burn” which means they essentially flip the ship backwards and accelerate to slow the ship down which also creates a 1G atmosphere. Basically imagine if you accelerated halfway to the store by flooring it in your car, so you’re pressed against your seat. Then halfway there you whip a 180 and start applying the brakes which also pushes you into your seat because you’re going backwards now. That’s it. That’s how “artificial gravity” in the Expanse universe works and it’s really cool! There are other details, and some changes like “Belters” who can’t handle full gravity accelerate slower and it actually gives Earthers an unfair advantage in warfare, shipping, and exploration because they can literally get everywhere much faster without getting sick from the gravity. For anyone who likes “hard” sci-fi (that’s where the science is more thought out, based in reality and nothing just works because it does.. Star Trek is Soft Sci-fi because a ton of the technology is just nonsense. The Martian is hard sci-fi because it’s basically all real and possible.) I highly recommend the Expanse. It’s an amazing series and super unique.

So slightly be dehydrated when you go to space

This is probably the best counter argument of why sci-fi involves anti gravity technology. Humans need precious gravity. So it would make sense to design a ship either around gravity or commit technology to create it.

This is why they sit, when they return to earth.

A daily visit to a centrifuge aught to sort them out

That's why aliens have such big heads.

i think the record for being in space is longer than a year

Imagine how weird the saliva would be to feel.

So what you’re saying is space (when not trying to kill you) is trying to make life miserable. Gravity never lets me down 😊

When they talk about aliens with big heads this makes me wonder if those effects have something to do with their physical appearance

just tell the astronauts to turn upside down 👍👍

Heats start turning spherical too which is terrible

dang as someone with EDS and POTS i might need to go to microgravity... or space

They need that 2001 Space Odyssey station.

It's because they're hanging upside down to full everybody.

Any long distance space trip would need a spinning section to generate gravity and astronaut would have to spend some time in there on a daily, at least that's the most realistic solution I see.

So, maybe we are stuck on earth with only occasional forays into near by space.

CST can help reduce swelling in the ventricles

I forgot his name, but i used to watch the Canadian astronaut’s videos when he was on the ISS
