I remember when the Sci show first branched off into its various flavors. Has it been so long? Well, as long as we still get to see our favorite faces and get regular space news and information, I'll always be satisfied. Thanks for all of the hard work!
I know it doesn't change the amount of content for Sci show space(I hope), but I am still sad to see it go. Sci show space was my favorite from the team.
Hanks gotta buy another yacht. Cutting expenses, first Sci show psych & now Sci show space. By putting everything in one channel each topic can publish less often while still appearing as an active channel that regularly puts out content.
@@Izandaia hank doesn't have a yacht let alone "another yacht". Must be your first day on the internet. Which makes it ironic that you say I don't know anything. At least I know what sarcasm is...
This is the last SciShow Space video on this channel?? I'm glad to have here to witness it so soon after it was uploaded. Looking forward to seeing the hosts on the main SciShow channel continuing their journey to teach us wonderful space facts and share fascinating space news 🖖
literally been subscribed to this channel as long as I can remember being on youtube and while I consider myself young not everyone would agree... The point being I am rather sad to see this channel close down. Even if it is essentially just integrating with another channel I have been subscribed to for just as long... :/
@Patrick Hudson likely. He has stupid rants on his personal channels all mostly political in nature. Why I avoid watching the main channel. Get enough woke crap everyday. Science is truth and alot of what he states as factual, is indeed conjecture.
@Patrick Hudson Scishow Space has its own dedicated presenters, with Hank only showing up from time to time. No, there's actually been a bunch of YT channels consolidating recently (another one this week was TLDR) so this is likely a YT-wide thing
If the content quality remains the same, does the specific channel matter? The only downside I can think of is for viewers highly focused on space science who will now have to scan the main channel for specific content. Is there another downside? Does anyone know the motivation to merge channels? The Algorithm?
Does this mean episodes will come more often? I don't mind the two channels I enjoy them both. But if they will become one, it would be nice to see a extra video or two each week. It's nice to learn about the world and universe, especially new things I'm not in the loop about.
If you use Virtual reality head sets for VR games, there is a rating for games that may cause motion sickness such as roller coaster rides or ISS simulator. Your eyes are telling you one thing and your vestibular system is telling you something else and you can become quite sick. I think that subjecting astronauts to such games would be a way to know who is subject to motion sickness or not. And it lends weight to the sight V vestibular system hypothesis.
What I liked about Sci Show Space was that it collected the space stuff in one spot. I could subscribe and not have clutter of other science stuff I wasn't interested in my feed. And now it's gone.
space dizzies sound a lot like VR dizzies. takes a few days to get over the motion sickness of playing VR also. interesting to think it could be ear crystals that cause such a difficult transition on the perception of movement in uniquely different environments than we typically need to make our way through.
But didn't you branch off this channel specifically bc space was so popular? I'm sad to see it go ive been subscribed for these 9 years but glad I won't be losing content bc im already subscribed to the main channel and have been for over 10 years! I look forward to your new content back on your og home channel!
I remember hearing about tests involving simulators which showed a video feed that differed from the motion of the simulator, and that seemed to cause the greatest motion sickness. The otolith asymmetry hypothesis seems promising
This is why motion sickness is so prevalent even among experienced fighter pilots (let alone us regular folk) when they use simulators where the generated motion doesn't exactly match with the visuals. Doesn't matter if it's a professional flight sim, the newest VR ride at an amusement park, or whatever. I know that I'm prone to motion sickness anyway, but those rides, my god... I'll be throwing up within minutes.
Interesting... In December you said you were cutting back on Space videos, now you are consolidating to your main channel? This does not sound like the SciShow Space videos aren't doing very well.....
Motion sickness is common in orbit free fall. Having a rotating section with centrifugal gravity may control (or worsen) space motion sickness. We need gravity for our health. Eventually, there will be rotating space ships and space stations with centrifugal force artificial gravity. Thanks.
This might be a stupid question but hey, it only takes asking one stupid question once to know the answer forever. Why do Astronauts float in space? Like I know that it's all "Zero-G" and that the ISS is really just falling towards the Earth and the curve of the Earth allows them to continue that perpetual falling. I get that, but why do they float? I mean if you think about gravity and think about it in terms of, oh the closer I am to this object with this massive gravity; the more intense the pull will be, then how do we still have the moon locked on to us in its own orbit? If the Astronauts are floating that close to Earth, why isn't the moon just going pew into space? Does the gravity differ? Is there something I'm missing? Is it some misunderstanding I have of gravity? I'm really curious so if anyone could answer that would be awesome, thanks!
Hımm... so strange. You send humans who lived on a planet for hundreds of millions of year that had 9.81 m/s2 attraction to a space with none and wonder why they are not just OK.
This sucks. Will SciShow Space have a separate section or play list on the main channel? Most of the regular programming does not interest me. Others might enjoy the fruit flies, skateboards and robots I see on the home page. We're gearing up to go to the moon again!
Thank you guys for getting me into learning more about space your the reason I got the highest grade in my faith grade school in my science class sure it was a long time ago but hey why not As well as many year other videos you've uploaded over the years So thanks Sci Show
Tis is a total bummer. I look forward eagerly to SciShow Space episodes coming out and this will leave a big hole in my viewing pleasure. Perhaps a final farewell retrospective episode should be aired?
Sea sickness is definitely a "thing", which seems related to SMS. The one thing that I noticed "water world" got *right* was "land sickness". After being on the water a few weeks, sailors definitely can get nausea from the world NOT moving constantly.
But pilots get sensory conflicts quite often in instrument conditions. In fact that’s why ignoring your senses and focusing on what the instruments tell you is a large part of the instrument rating, but we typically don’t get feeling sick - jus sometimes disoriented.
I don't understand why some people getting SMS and some people not getting it is a problem for the sensory conflict hypothesis. After all, some people get motion sick reading in a car and some don't - or is it that sensory conflict is also not a complete explanation for why people get sick reading in cars?
o7 ... SciShow Space, you will be missed. You were one of my favorite channels. I hope to see a revival of you soon. HANK! BRING THIS CHANNEL BACK TO LIFE!!!!!!
Was hoping SciShow Space wouldn't get axed as well after you axed SciShow Psyc, sad to see it go. Will the frequency of uploads remain the same on SciShow or will it increase to make up for the missing content here?
5:38 Talking about SpaceX and the Polaris Dawn mission(s), which will use a Crew Dragon launched from a Falcon 9, but uses an image of NASA's Artemis I launch using an Orion crew vehicle on an SLS rocket . . . Classy.
As a cruising sailor, it's common for long-distance cruisers starting out on a long voyage to get sick as a dog the first few days of every trip. Even as short-distance cruisers, Neither my wife nor I usually get sick on a day-long sail, but after being ON the boat for a weekend or week or month, when we get back to our slip, I get a little land-sick while I'm taking that luxurious shower. Mostly it's a bit like having drunk too much, the room spinning mostly
My hypothesis: PTSD. Kind of. It's all in the head, right? When people go into space, the body adapts to the new setup. But the astronaut is fully primed for this, all his/her training is designed for that. When they return, the body has to readapt. But the astronaut is relaxing, feeling safe again, and does not invest the same attention and energy into this equally challenging adaptation. Am I right in guessing that there's no training for hugging dirt again? That's how I explain WHEN it occurs, because the physical challenge is similar but the psychology of the situation is diametrically opposite. Therefore I would predict that people who are always on, always calm and professional, never enthusiastic, never relaxing, the no-fun crowd, would not experience motion sickness upon return. Au contraire, people who operate by temporary boosts of effort would be prime candidates. Also, the more challenging, more demanding people found space, the more likely they are to experience these symptoms upon return.
Sea legs, when sailing on the sea.... I'm never sea sick when out sailing, but when coming back ashore after several days at sea, it can take days of feeling woozy before my land legs return. I'd be sitting absolutely still, and the room is gently slopping back and forth around me. Vestibular disturbances...
Otoliths interact with Magnetic Fields as well as Gravity. Human physiology is currently experiencing a myriad of adaptions in preparation for their potential Future as a Wandering Species (Spacefaring). Vestibular Sensory Seeking 'disorder' is an intermediary stage of Human otolith adaptation. Humans that are identified with this 'disorder' and the subsequent generations of their progeny will not experience Space motion sickness.
I’m super angry about this video for leaving out one important theory: the nystagmus hypothesis. This links motion sickness not with the ear, but with the eyes (via the vagus nerve). Specifically, the stretching/traction of ocular muscles caused by the motion of the head not matching the motion of eyeballs. Context: I have uncorrectable strabismus and I couldn’t understand why I got so nauseous when I watched TV or something in my periphery didn’t match my “main” eye. Turns out it was motion sickness caused by my brain trying to force a resolution of the conflicting images via constant, involuntary eye muscle adjustments.
Well this really sucks, because that means it's the end of SciShow for me. I don't like a lot of content on the main channel, and you post too many damn Shorts over there, so I won't be subscribing. Sigh, goodbye Hank, Caitlin, Savannah, and Reid.
Sad, but I understand. If everything goes onto one channel, the main channel gets more uploads and that gives it more views and keeps it in the UA-cam algorithm. The UA-cam algorithm, a double edged sword 🤕
I mean, we do. The vestibular system is mediated by fluid in the semicircular canals, and that gets confused in microgravity with the liquid not pooling at the bottom. Ok, I should watch the video now.
When Physiology doesn't explain the problem, often psychology does. Pity psychologists dropped the ball. I think (from never getting seasick) that it has to do with the psychology of being able to be out of control. That is, if you can take altering drugs and be fine, you can deal with motion sickness! If you have to be in control all the time, you are sickened by the loss of control.
Scott Kelly reported at first that he was fine returning from his year on the space station, although weak -- despite having faithfully followed exercise routines. Then the 3rd day he woke up his ankles were the size of his thighs. It appears his body had "forgotten" how to move liquids around. Got worse and worse and took him over a year to recover ... and was painful. This guy had done some very tough jobs for the American military, but near the end he says something like "... if America still needs hard work done they can ask someone else." "Endurance" is his book about his experiences in the space station. Great read.

Well, we have symptoms on the ground which is also not really known why it happens. MDD is one, which is basically they the adaptation when changing reference frames is broken and sort of never works. So after a cruise or flight, the dizziness never subsides or very slowly.
3:25 What's happening is that the spinning around in "zero-g" causes some otoliths to become dislodged and float around in the inner ear, causing the astronauts to get a perpetual state of BPPV, and without gravity, they can't do Epley or other maneuvers to fix it. 🤢 This explains why it happens to some but not others.
They were test pilots. Each with decades of experience it shifting reference frames. They were also strapped in with little chance to move around. It’s not a fair comparison.
Christ! Has it really been nine years? I remember when Scishow Space was originally spun-off the main Scishow channel! Sound off in the replies if you've also been here for all of that time!
I need a solution here on earth too. I wanna be able to play Racing games and similar in VR. Anything that doesnt have teleporting as movement is unplayavle to me.
First Scishow Psych, now Scishow Space. The consolidation continues. There's probably a lot of audience overlap between the Scishow channels so I guess this makes it easier to deal with advertisers.
A few years back they split the patreons and I felt bad because I could only support one, so I stayed with the main channel even though I liked both. Now they are combining the two channels, so I at least feel like I'll be giving Space the love it deserves again. But I wonder how they'll handle it on Patreon. In any case, my support at the main channel will continue.
Ha! thats Funny! didnt you make this branch of sci show because you had too many sapce videos on your main channel? I guess space is sexy enough to take front and center stage again! yay! :P
We are a part of the environment of Earth, not just visitors. We survive with the Earth and we end when it can't sustain us. Technology may one day allow us to mine the moon and retrieve material from Mars and beyond with human analogs. But, this idea of putting humans there is foolish and likely to end in disaster.
I don't get sea sick unless it's terrifying waves ECT but a week out to sea and then step foot on land and oooh I have to buckle up I have to shower have some libations and a bed!
I haven't seen the video yet but my assumption is that due to the inner ear having evolved in an reference frame in constant motion(acceleration) and now they're occupying a reference frame without constant acceleration(in space away from larger accelerating bodies) their ears have to compensate for this lack of being in an constant acceleration and it is this compensation that in turn causes a feeling of motion sickness. Kind of like a reverse motion sickness, due to the balance center in our ears needing to be evolved to be stable and centered like a bubble level in constant acceleration due to living on the surface of the revolving earth, the lack of this acceleration is throwing our sense of motion/balance off.
i get why they would want to be able to predict who will get motion sick in space since it cost so much to send a person but isnt that a step too far? you cant really predict who get motion sick on earth right? its just easy to test it. maybe im misunderstanding something but feels like being able to predict it shouldn't be a criteria in figuring out the cause. we understand earthquakes but we cant predict earthquakes in advance.
I think the move is a great idea because youtube's stupid Algorithms show me sci show but rarely sci show space so this means I am more likely to get them all :)
Think about it, the astronauts aren't actually 'still' in space. They are linked to the motion of either the vehicle that took them to orbit or the station they docked with...none of which is truly motionless!
I mean, strapping to the top of a missile and launching into zero gravity at crazy speeds then maybe staying there seems like the perfect recipe for nausea.
I remember when the Sci show first branched off into its various flavors. Has it been so long? Well, as long as we still get to see our favorite faces and get regular space news and information, I'll always be satisfied. Thanks for all of the hard work!

Inner ear fluids. Duh. Car sickness, video game sickness also works the same.
Well then...time to move to SciShow I guess!
Here's to the next years.
Ha! thats Funny! didnt you make this branch of sci show because you had too many sapce videos on your main channel? I guess space is sexy enough to take front and center stage again! yay! :P
We are a part of the environment of Earth, not just visitors. We survive with the Earth and we end when it can't sustain us. Technology may one day allow us to mine the moon and retrieve material from Mars and beyond with human analogs. But, this idea of putting humans there is foolish and likely to end in disaster.
Maybe YOU don’t, but over here, WE certainly do.
I don't get sea sick unless it's terrifying waves ECT but a week out to sea and then step foot on land and oooh I have to buckle up I have to shower have some libations and a bed!
Well. Have to keep fighting/playing the algorithm. Sad
I haven't seen the video yet but my assumption is that due to the inner ear having evolved in an reference frame in constant motion(acceleration) and now they're occupying a reference frame without constant acceleration(in space away from larger accelerating bodies) their ears have to compensate for this lack of being in an constant acceleration and it is this compensation that in turn causes a feeling of motion sickness.
Kind of like a reverse motion sickness, due to the balance center in our ears needing to be evolved to be stable and centered like a bubble level in constant acceleration due to living on the surface of the revolving earth, the lack of this acceleration is throwing our sense of motion/balance off.
I wonder if research has looked at the phenomenon that Simone Biles faced, the twisties It probably has something to do with these otoliths.
i get why they would want to be able to predict who will get motion sick in space since it cost so much to send a person but isnt that a step too far? you cant really predict who get motion sick on earth right? its just easy to test it. maybe im misunderstanding something but feels like being able to predict it shouldn't be a criteria in figuring out the cause. we understand earthquakes but we cant predict earthquakes in advance.
why did you guys stop making videos? It's been a year!
I think the move is a great idea because youtube's stupid Algorithms show me sci show but rarely sci show space so this means I am more likely to get them all :)
Think about it, the astronauts aren't actually 'still' in space. They are linked to the motion of either the vehicle that took them to orbit or the station they docked with...none of which is truly motionless!
That sucks, I'm going to miss the space focused content that isn't mixed with non space stuff.
Saying good bye to SS Space is so sad! Thanks for all those ears! I'm gonna stay tuned on the main channel.
I mean, strapping to the top of a missile and launching into zero gravity at crazy speeds then maybe staying there seems like the perfect recipe for nausea.
At least I get to leave a comment on this video within a day before we go bye-bye.
I mean, I get motion sickness when I'm in a VR simulation of space.
2:20 I thought the Gemini program was pronounced geminee, not geminai?
I’ll volunteer for testing - no vestibular system here…
i wonder if this has some similarities with how people with vr equipment feel dizzy at times. I heard something in relations to the whole ear thing.
Aww how come this channel is being merged with regular sci-show?
Bruh why, this was perfect to binge watch
So at lot less Space content unless SciShow picks up its production cadence and schedule.
