Hank answers a SciShow viewer's most pressing question about what happens if the human body gets exposed to space. Would your head really explode?

what an amazing way to go out.
the earth under your feet, everything that has ever been, so tiny.
15s later you enter eternal slumber, entering wherever your subconscious brings you.
if you think theres a heaven and hell and you think you deserve hell, you'll burn there.
if you imagine playing games forever, there you'll be. nobody to shout at you for playing too long n=and friends telling you to get a life.
What will if you get a cut in your blood is being exposed to the vacuum of space because if an astronaut was exposed to space is probably because the spacecraft crashed and they may have a cut on their body
How stupid this video is, they tested an astronaut suit in a vacuum less than the moon and it leaked and the astronaut said he could feel his saliva start to boil on his tongue and he passed out............not to mention an object in space does not need air to transfer the temperature to the object the object itself would conduct the radiation of the sun or the freezing temperature of space, this was easily demonstrated by shining a light at a thermometer in a vacuum, the thermometer itself was all the matter that was needed to conduct the heat
What a load of crap!!! If course your blood would boil. Hi watch videos on YouTube where people put their have into a chamber and start a vacuum inside. Heck, just take a vacuum cleaner and put it on your neck or stomach. And after a few seconds you can see your blood bring sucked out through your skin. iE..a big hickey. That's the blood in your body boiling and coming to the surface because there is no pressure holding it in. Or in these cases being sucked out. Boiling doesn't "technically" mean actually boil like how water boils on a stove. Boiling is when the little bubble in your blood start to get stimulated to being sucked out and separated from your actual liquid plasma (blood)
I know that this is kinda off topic but how far exactly can the human eye see i mean we can see the moon and the sun and stars and there extremely far away is it just because there bright and if that's true couldn't we see like an Infinite amount as long as it's something super bright
We can only see light that is reaching our eyes. The further something is away the darker it seems to be. So you're right, we can only see stars because they are so bright. But we can't see into infinity. Light travels at lightspeed as we know. So the light of a star that is 4 lightyears away travels 4 years to Earth. But the universe is only about 14 billion years old. So light from stars that are more than 14 billion lightyears away didn't have enough time to reach earth yet. So the distance the eye can see is limited by the big bang itself
So there you have it, all you annoying people saying that the “Leia poppins” scene in the last Jedi didn’t make since. You don’t explode or implode, but you will die shortly. You can survive 15 seconds before blacking out and she used those 15 seconds to get back to the ship before blacking out. So shut up.
SPACE THRUST DEBUNKED!!! Look :) If you are standing in a vacuum chamber, you will NOT move until you stretch out your arm against a wall. If you blow very very hard since your body is very dense, you will move because the AIR is stopping AGAINST the WALL. It creates something, a barrier against something, a physical object material you can push against. NOW! What happens if you REMOVE the WALL??? Thrust in the vacuum of space is a HOAX it is FAKE, do NOT THRUST NASA!!!
In the vacuum of space, there are no gravity and negative pressure. No way for thrust to form. A bullet works cuz there are two hard parts, gas and liquid does not fit in this category. The bullet works cuz the two hard parts HOLDS together. A thrust in the vacuum of space will work if you can physically screw the air/gas that is coming out of the rocket to the chassis of the rocket, something that we can not do. Thrust does not work in space. It has EVERY thing to say witch material is used. Recoil can ONLY happen when there are two hard material parts connected. When the exhaust leaves the rocket THEN it still hangs in a sucking vacuum and it's no logen CONNECTED to the rocket. No thrust can be created. If the rocket was spitting out something of HARD material that is connected physically to the rocket, then the push could have been made (like a minigun propulsion system). You can not glue exhaust to the rocket, there for the thrust won't work. The vacuum of space is PULLING the rocket in all directions. On the surface of the earth it is positive pressure that is pushing everything IN. So the rocket can travel and thrust in positive pressure where Newton's 3 law WORKS, but FAILS in the sucking vacuum of space.
If you stand on a skateboard and throw a bowling ball forward, that force will push you and the skateboard back. It's not because the bowling ball is hitting a wall or air. This is how thrust works in space too. The act of pushing something out one end, causes the other end to move away. Your example of something blowing air very hard out their mouth would work the same way, wall or no wall.
there is no vacuum of space.two opposing pressure systems can not exist side by side without a solid barrier in between.It would be like having a can of spray paint in your hand,and taking away the metal can,leaving just the paint and expecting it to just magically be there.something called equalibrium proves there is no vacuum.you been lied to kiddies...nasa is a big phony.stop buying into it here on youtube and sounding like lost sheep,saying things like.."duh,thats fascinating"
So you mean that they would not explode, neither freeze in the space since it is vacuum without air? Then why do the astronauts need a heavy and expensive space suit with many layers? It should then be enough if they had an oxygen tank with a mouthpiece and sweatpants. I can smell the rat. The explanations in the video don't stick together with what has been told in earlier years. And I'm very skeptical to the Moon landing. And if the radiation, heat, and cold was not a problem in the space, then why did the Moon modules had a layer of foil paper, around some parts of the module if it was not for protection? Protection for what?
Attention!!! sci show although there is no medium for heat conduction but a process known as heat radiation states that any body above Absolute Temperature (0K) radiate heat in the form of electromagnetic waves that is heat is radiated out of the body without any medium
No so sure about "you wouldn't be able to resist the pull of the vacuum". Basically it's a 1 atmosphere depressurization, so about the same as to go back to the surface from a 10m deep dive with air at 2 atm in your lungs. Certainly uncomfortable but it seems possible... Anyway, the most scientifically accurate exposure to vacuum in scifi is probably in 2001 : A Space Odyssey filmed in 1968 ...
There actually is no pull. There only is pressure in physics...so why do you think it would pull the air out of the lungs if there is no outer pressure? If you exhale there of course isn't much to inhale then but there is no reason the force of your diaphragm wouldn't keep that in. If you hold your breath there is actually no other hole it can escape through since all the others are connected through your nasal cavity.
Our body, lungs and everything can endure pressures on earth from 5 psi up to 308 psi (evidently, not theoretically), so why do you think 5 less psi would change anything?
Your obviously an idiot. All of the fluids in our body remain fluids because of the air pressure. If there is no air pressure than all of the fluids will start to boil. That includes water in the interstitial spaces of the cells in our skin and then our blood. Moron.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
