I feel like the question in the title wasn't answer. Which seems to happen often.
|Jake|C| Actually you know the answers already - without gravity, 1. our heart in our body will not work as hard pumping blood in our body, so it will become weaker over time.2. our bone will lost mass over time, we become more fragile.3. humans has difficulty procreating in space due to loss of gravity interferring with sperm fertilsing eggs.4. we may become mad/crazy over time due to vacuum, there are no air thus no sound can travel in space. Basically you hear nothing and your hearings may decline over time since it is seldom used.5. Everywhere in space it is dark, may be with some light coming from distance stars. You also go crazy due to lack of light...it is like 10 times worse then staying 6 months in the north pole without light.6. If you are still healthy both physically and mentally after the above, cancers from cosmic radiations will kill you eventually.Conclusion: Our squishy body is not designed for space travel at all....
+Vincent Jack The title implies being in space with no suit, IN the vacuum of space. There was no mention on what the vacuum of space would do to the human body, only what living on space stations and zero gravity would be like, and explaining how the suits work, like not even close to what the titles says.
okay, sorry. my mistake.
+Udalix Llew You could always volunteer to be exposed to the vacuum to see how it affected your body, in the name of science, but unfair to ask it of anyone else.
+Udalix Llew the answer to that is you'd immediately implode... Do NOT hold your breathe because the air will push out of your lungs in all directions and implode you. By releasing your breathe you gain maybe a couple seconds of life. But ultimately you will die of lack of oxygen and your body will freeze near instantly as the heat from your body dissipates.
Congrats your question was answered. But still he explained the logical reason why the body is being destroyed in space. Most all media, expecially UA-cam, exaggerates and if you can't accept it, then delete your account and stop browsing.
Its literally a comment thats like saying "I feel the President doesn't follow through on his word. It seems to happen a lot." We all fucking know, pointing it out was entirely mute.
you can hear someone laugh in the background just after 2:30
NO, IT'S THE SOUND OF THE INFIDEL BEING BEHEADED!
ClubThugAgent sounds more like a sneeze to me.
the timing just seems a little to right, i still think it is a laugh
ClubThugAgent I vote that it was a laugh. His facial expression of disgust and bewilderment was HILARIOUS. I was in Starbucks and literally busted out laughing at 2:28.
Space sex is possible, trust me I've played mass effect
Let's be honest, if we were to attempt long terms space travel, we'd probably rotate the space craft to reproduce the sensation of gravity. Then only stop the spinning when you need to dock or land. It would fix the muscular degeneration issue and sex should feel basically the same.
It seems to me that, so far, there are three main problems with long term space dwellings; radiation, micro-asteriods and gravity.
Water is actually a pretty good radiation shield. Arrange your water tanks around the outside of the ship or station.
Micro-asteriods are pretty much untrackable and they're everywhere. All you can really do is get very good at patching holes. One thing you might do is arrange to keep the outsides of your water tanks as cold as possible while keeping the insides a little above freezing. Then, if they're holed, water flowing through the ice hole will freeze and seal itself, (hopefully.)
So far, there's only one way to simulate gravity; spin the spacecraft and use centripetal force in its place. This means that, (for instance), a Mars ship would probably be a spinning wheel with thrusters and other things that have to keep still mounted on the axle, like the Discovery from the movie "2001: A Space Odyssey."
2:30 you hear someone laughing in the background lol
That was an intense lesson.
What about the ship design that looks like a big wheel and is forever spinning? It would put out a constant force of one G and wouldn't feel any different from Earth. Wouldn't that get rid of the sex and bodily problems?
you don't need to explain how test tubes plus works every single video!
I am so addicted to this channel, please keep up the amazing work!!! :D
I really enjoy these videos, the whole channel is awesome
WE use the KISS principal for keeping the people alive.
Earth is the perfect example of how to do it. We build our ships with the same defences the earth has, we give them an artifical magnetic field, and an atmosphere to burn off collisions. (It will take much more than that for the big giants lol, but its a start how to shield a ship.)
Would being in zero gravity effect the development of a toddler?
One thing I'm sure would happen is they would be very, VERY frail. Astronauts returning to earth from the space station have to go through physical training because all that time in zero gravity makes their bodies weaker.
Think about it- every day that you stand up and move around, your body is resisting gravity's pull on you. We're so used to it- walking around, lifting things, using our muscles- but once you're in zero-g and your body is no longer resisting against much of anything, you lose muscle mass and tendon strength fast. Exercise is hard when things don't weigh anything c:
So the toddler would spend its early years with no exercise at all. They're already weak, but with no way to gain their strength, I'm not sure they would even be able to move when they return... I wonder how long they could survive?
It's unfortunate that man has yet not built a test centrifuge in space.
Fucking probably come on man
I was thinking about artificial gravity. Centrifugal force could give you something like gravity for your body. But I think it would be quite big. It is worth the try anyway, because it could solve or at least ease the problem.
the short answer is yes....circulatory problems, muscle atrophy, optic nerve swelling....etc, etc.
Maybe u could use small pieces of Velcro places in special spots around the inside of the suite... The solve the random itch problem....
Once you put things in space, there is still gravity. That's why satellites revolve about the Earth as opposed to just travel in a straight trajectory away from our planet. However, there is no 'ground' or 'floor' that is pushing you 'upwards' like there is when you are on Earth's surface, so your body doesn't give you the sensation of being under the influence of gravity.
Falling free by Lois McMaster Bujold; is great work fiction that covers the use human genetics, to make the human body more compatible for living and working in a low gravity environment. It also covers the dark and emotional side of human genetics
Very interesting talk, you brought up a lot of topics I've never even considered before. I've been fascinated with space since I was about 7yrs old, and our solar system was my choice of project. Ever since then I've always loved Sci Fi (especially the hard fi side) movies and video games. I'm currently playing a great game/space sim. called Elite Dangerous, which is set in a fairly accurate recreation of our solar system. It has 400 billion stars, with the vast majority of those stars having their own fully working star systems, that you can explore. The game allows you to pick a trade, be that Explorer, Miner, Bounty hunter, Trader etc. It even has landable planets that you can drive a buggy round, and all the planets have true orbits, so true day/night cycles etc. I would recommend Elite Dangerous to any gamer with a love of Sci Fi/space exploration.
No one has ever been outside of the pull of gravity, not even astronauts. Remember, the international space station isn't floating in space, it's falling, non stop, it's because of its speed that allows it to remain in space.
yes no one has been out side of gravity but one who is falling with out end (orbiting earth) would be able to experience 0g thus the same effect as no gravity
Now this is just my uneducated opinion. With weightlessness being such a huge issue in space and it's effect on the human body; I think the biggest thing keeping us from making any trips further than the moon is that we need to figure out a practical way to apply artificial gravity. Most likely through centrifugal force. This would likely negate many of the problems we currently run into with space travel.
i love this series
if you at some ship design they have a ring that spine. the ring is to simulate gravity by producing a force outwards(i forgotten the name of the force it somehow).
Nasa is so old school. It shouldn't be so difficult. I should start my own space company.
Phenomenal presentation! Thank you.
I had not thought about the medical effects of space on the human body until I watched the Expanse and it was mentioned in one of the episodes about the effects of non gravity on cuts etc. Then I read a bit more and all of a sudden Im reading about the effects on eyesight the effects on teeth and
radiation and tardigrades..space can be very dangerous the the human body. Im rather hoping that the
advances in technology and esp after singularity,unless Skynet has taken over, we will have solved
some of these problems and can go trotting about space.

With the title of this video, I thought u were going to mention how one's blood would literally boil in a vacuum...concern for stratosphere jumpers as well
You know, I would think that being out in space and not having your body fluids distribute evenly would do something to your hormones to where you wouldn't feel too much of a need for "Sex" or "Masturbation" because in order for you to feel one or the other your hormones would have to be active for that to happen, so even if your mind is saying, "Yes" your body might be saying, "No!!!"
Trace, can you please tell me where you get all these shirts? I need them.
I would assume artificial gravity would eliminate most of the issues the body has with space travel. Obviously we'd have to perfect artificial gravity first but I'm confident we'll get there.
already there just pointless to build it when we have to find a better way to travel first.
Step 1: artificial gravity
Step 2: self sustaining fuel
Step 3: all the space fucking u want
Why aren't we using magnets as radiation protection in space?
I bet even an average sized electro-magnet could protect the craft and personnel from radiation to a degree.
+Jack Hughes Good question. It's probably consumes a lot of energy and it won't deflect all materials, but only ionised radiation and metals. And you can shield the spacecraft anyway with known materials to block most radiation. Still I'd like to know if it's really feasable an EM shield.
Weight, don't tell me. I think I've got the answer.
From the thumbnail (a body floating in space with no EVA suit) and the title, I expected something else from this video. Any chance you might get to do what I expected? What happens to the human body in the vacuum of space without an EVA suit?
If we know a magnetic field is produced by an iron ball rotating through a material, can't we just build a miniaturized version to go on a space ship? If we can figure out how to build a micro nuclear reactor for probes, I'd think we can figure this out.
In theory we could but the point is we can't get a magnetic field strong enough (yet) to stop the cosmic rays
and once we do the field would mess with the power system being that it also uses magnetim to operate
3:12 I read somewhere that astronauts have a Velcro strip in helmets to scratch their itching noses.
If you haven't heard already, people have started a fundraiser to make a adult film in space
Just based on the answers given here, I don't think conception would be possible. Trace said that the new blood vessels that your body was creating before you head up to space will disappear within a few days correct. So how is a fetus supposed to develop blood vessels in zero gravity if a full grown human can't?
Maybe test tube babies would be a more likely possibly. Keeping a fetus in a pressurized "goo" chamber would be the most viable option. But then you'll run into several issues for the child after it's "born". Would it stay in a pressurized area for the rest of its life while the adults that went up originally stay on zero g to repair the ship? Or (disregarding radiation) could we survive in the atrophied state of our bodies long term? How would this affect our life spans? Would we be breeding the first race of humans to permanently live off of Earth? I would imagine the trip back down would kill them since their bodies would be atrophied beyond imagination.
if food substances is directly exposed in space what happens immediately?
Sex in space is difficult, you need gravitation (or something like it) or artificial insemination (which may not work), and space is not good for human development, bones tend to be very brittle.
The title is misleading, it says "How The Vacuum Of Space DestroysThe Human Body." It should say "How Space Destroys The Human Body." I wanted to see a video that talked about what would happen to a person if they went space walking without a suit.
I love this show! And you're so pleasant to listen to, great work!!
Keep making these awesome videos please!
Greetings from belgium
It would have been nice if the video actually answered the 'question' posed in this video's title!
i dont know how far our robotics industries have come but what if they made metal hands? if so many injuries happen to the hands, place the hands further in the suit and attach robotic hands that extend out.
their must be some engineers that could install a component allowing for near complete manipulation of fingers(at least to the point of tool use.) plus the fingers wouldnt have to be nearly as thick and irritating.
im not an engineer, nor are any ideas on youtube ever used... but its a reasonable opinion; if hands are the most injured body part, find a way to optimize it.
just use centripetal force (With the RCS)to create artificial gravity and then you would be fine just don't look out of the windows while doing that or else you'll get dizzy
thanks for the video, and the laughs =)
I don't think sex in space would be that problematic, and not a problem at all in low gravity, like on Mars. I am much more worried what the lack of gravity would do to the developing featus though.
Long term survival in space, as you mention is often shown in Sci-Fi, is possible with even today's technology. The issue is more of the cost. Building a massive station with rotating core to simulate gravity and then all the zero gravity issue are no really much of a factor. Given our current technology though the cost of moving that much material into space would likely bankrupt a country.
Most Sci-Fi gets around the issue with things like artificial gravity generators. Though this is done for the convenience of filming more than trying to create a realistic future, as filming a whole movie in weightlessness would be extremely difficult and costly. And in cases of novel's people are so familiar with motion in gravity that it is easier to just having people walking around, especially if some form of combat is going to happen and needs to be described. All around though it's just easier to pretend their is a source of gravity on the ship for terms of story telling since that's what people are use to experiencing in their everyday lives.
Could you recreate earth's gravity inside a spaceship?
The mirror is really for fighting aliens with lasers
How are space and time connected?
The only way to do it is to build a tiny earth and make it our vessel through space! We need to build a Death Star!
You got it wrong, there is gravity in space, what I think you meant is that you feel weightless, or are falling around the earth :D
did you go to space and do readings or did you read a blog?
space is the final frontier, what we know is like when cave men learned to go fishing or diving at the beach. its gonna be awhile until we build a boat that sinks off the coast in a storm
All of the problems you've outlined here are solved with artificial gravity. An O'Neill cylinder would provide sufficient gravity to not only accommodate human body makeup, but would also allow us to grow plants for food/oxygen in space.
extra large, immanence and unbelievable.
Dude who spent a year in space returned to earth slightly taller and younger.
Do suction cups work in the vacuum of space?
no
The title is somewhat misleading,I thought it would be more like the video on what to your body does when you die. Still a good video though.
I really enjoy these 😊
We're pretty much done with space travel. May get to Mars, possibly, but that's it. Better work on using probes to establish whether there's life elsewhere in the solar system and telescopes to see any signs of life elsewhere. Do it before economic decline or collapse makes it impossible forever.
My Question: who and how did they invented space suit before they even reach space?
May be u dont know that we can achieve speed of light but by the teleportation technique can help us to measure the space or to reach remote point.😉
I did NOT intend to watch this, but damn, that was super interesting! :D
Is there any legitamacy to making artificial gravity space stations like in "Interstellar" an 2001 A Space Oddyssey"?
Does space destroys our body? NO TIME DOES.
You didn't say how the MAG works for people with vulvas.
I think they consider it 10,000 dollars per pound, as they say your weight in gold so to speak, from what I remember?
Can you do a video about Nestle please?
Sex in space isn't a big issue (IVF can solve the issue), the big one is how _pregnancy_ works up there. And who wants to be the first to try _that_?
Matthew Marden actually delivering a baby in space sounds like you need a lot of straps, and belts, and people to make sure that the baby doesn't float off into the iss.
Scorpia Flueman
If it even managed to form and settle, the human form did develop in gravity and might not without.
Where did water come from?
If humans have created plants that glow, I'm sure we can make space-ficcient plants.
For the itch I heard a long time ago that they put a piece of Velcro on the inside of the helmet so they could rub their nose or whatever on it. Not sure if that's true because I can't remember the source.
I wonder if they could make artificial gravity someday.....
SuperKitt KattGirl they already can but is useless for the experiences that they make
SuperKitt KattGirl Google Nautilus-x.
SuperKitt KattGirl Rotation can create gravity.
+SuperKitt KattGirl Google an O'Neill Cylinder.

When we leave our natural habitat, we suffer. Man was created to live on land. Anything else is to fish for our death.
It will get to a point that the human body will adapt to space over long period of time but the downside will be that they want be able to return to Earth weak bones to bone loss and muscle loss and to renter the atmosphere and the gravity of earth would be too much the weak bones would be crushed kind of a paradox.
Spacesuits: They're too clumsy, and especially limit manual dexterity. EVA, by now, should be done by remotely operated vehicles. If a brain surgeon can operate with robotic hands, then why can't an astronaut perform maintenance with a virtual robot self taking all the risks? Of course, a different kind of suit is needed for traipsing around Mars or the Moon; perhaps something hard, like a lightweight version of the Newtsuit.
Chokin' that zero-G chicken. Lmfao
Is it possible to produce artificial gravity, and if so, how?
it is possible to create artificial gravity through:
acceleration - basically your always speeding up to created a force to pull you away from where your going, and the moment you stop speeding up you will have no gravity again (even if your traveling at a high speed)
.
centrifugal force - similar to how you can put an item in a bag then spin the bag fast enough so the item doesn't fall out. (this would create artificial gravity in two directions)
Rotation crates centripetal force which pushes outward causing an artificial gravity.
0.00001 (point zero zero zero zero one) sievert. How is that a mili sievert? Mili is always a thousandth of something. So a mili sievert is 0.001 sievert.
if we get 0.00001 sievert every day (as you say in the video), I really don't wanna get a mili sievert every day because that would be 100 times more powerful
love this guy! so smart and informative
Hey did he mention the diapers? Maybe they have a tube inserted in the nether regions to suck out the waste matter. So if they go to mars then the meat sacks turn into tofu?
Have they ever sent a dead body into outer space? That's the vid I was looking for
$10,000 per pound to send something to orbit... fail on opening line, priceless
is there anything space related that used to be science fiction but it is now a reality?
Van Allen belt magnetic field extends beyond the atmosphere.
can't you just push your self up and down from the roof and the floor with your arm then land on your leg and the force from your push goes to your legs, would that work?
would that count as gravity but for a short short time
+Robotickiller12 that would not work as you wiegh nothing in space. pushing your self like that would exert no energy at all. they do have work out machines in space but it's too complicated to describe
Leave only brain and spine and replace rest with mechanical parts. Turn your body in to space suit. Live forever + don't have any problems with space travel.
Just an idea. :p
The brain cant function without organs
Not Hating Just Stating Artificial organs. Basically all we need is one nano-tech organ that emulates them all. Trick brain in to thinking that everything is in its place. Generate all the chemicals etc.
Technological singularity demands something like that anyway. Another possibility is that we upload our consciousness on to super computer and then basically have avatar like robot bodies that can survive in space with no suit.
Actually I am a bit saddened by your reply. You see one problem and looks like you are ready to give up as if it is totally impossible. Do you realize how much opportunities you could miss with this kind of mindset?
Ask Shia if you don't believe me. Yes You Can! Stop giving up!
So nobody is able to explain the drowning n a spacesuit when u in a "0gravity" simulation; I meant space.
I'm asking for a friend
What to they do when they have to poop?
How does pooping even work without the aid of gravity?
Mrepifany There is a video of someone showing how it's done on the ISS, they use tubes to basicly "suck" it out. It seems very inconvenient
1:22 I'm confused... Where's the water coming from ?
some experimental space suits use water to lower radiation and as he stated before you do have a water based cooling system inside the suit
ya know how you were talkig about the gloves that try to keep from injuring your hands well why not try to make a led based glove to prevent the gamma and x-rays from injuring your hands
What? Is the video about the construction of a space suit!?
good channel
Hey Trace, why is your vision blurry when you look under water? #dnewsworthy?
why not put the lcd on the wrist
+Anthony Cupero Because hearts & lungs aren't in the wrist?
My question is... Is space a 'real' vacuum?
no but it is so close to it that there is justification to say it is
Skeet Skeet Ninja That's what i though.
It's weird that something as important as procreation has never been tested, i wonder if they ever tested it with animals.
When I first saw Trace, I thought, damn, what an idiot.
But then, I warmed up to him and now, I like him.
But I think the reason I thought he was an idiot, was his hairstyle.
Still can't make myself like it.
