So...expect 15 seconds of mind-numbing scariness. Got it.
I'd rather explode.
Except you would have a good chance of survival with little permanent damage if rescued within 90 seconds.
your skinn is flexible enough to handle that explosion
Mine numbing scariness and pain... BUT for the duration you get to see the beauty of space first-hand without a window.
Rusty Shackleford you won’t recognize anything your head WILL burst
ok
ok.
This is really weird....
Random Gaming Channel ok.
DNews Wait, why did Laci Quit? I'm just asking. I noticed videos before goodbye to Laci, She hasn't been around a lot.
Random Gaming Channel sexual harassment
woow they tortured chimps and dogs just to see how long they would survive? That is horrible.
*****
Its for the security of astronauts.
We don't really need to go to space, that is just curiosity.
Would you volunteer? or would you rather have people tested against their will? or would you test on animals? I know which i would prefer.
Dictor Clef how many people have gone into space and how many people have died from Ebola, i would go for the biggest group...
pinda kaas
It was before ebola.
How I want to die:
Inside a glass pod that is launched into a black hole.
I can enjoy the beauty of the universe, and be the first person to experience a blackhole.
i would completly freak out because i know im going to die...
Wouldn't be a long death? I mean, as you get closer and closer time would also stretch. Also you would have to reach a blackhole first, which may force you to start traveling quite sooner than when you expect to die.
To bad time would stop for you before you enter it. Meaning you won't get to experience it because all your cognitive abilities obviously freeze along with time.
I'm a potato?! that explains so much o.o
Steve Strangelove Hey, whatever happens as long as it isn't insanely painful, dying via blackhole is a worthwhile death....
And if those "what if a black hole has a universe inside it?" theories are true, then I'd also be the first person (from earth) to travel between universes.
I like how you say its not as bad as hollywood films depict and then go on to describe how every molecule in your body will swell up or boil into a gas.
Darn. Don't you hate it when your best friend pushes you into a space vacuum?
Shawn Faris Someone will do that as a prank in 50 years & put it on SpaceTube.
+s4ujcd Naw, there will be laws involving that
+s4ujcd SpaceTube sounds like the new porn site in the future....
+gaeger m i could see it now "hot alien near you"
Erick Hernandez what i can see is lots of alien tentacle porn. lots and lots of it.
Watch the expanse, one of the main characters did a suit less ship to ship vacuum transfer that took about 15-20 seconds. A hyper oxygenated injection was taken about mid way but the effects on the body were clearly displayed.
At the beginning I was like "Holy shit what fucking sick mind would do this to over a hundred dogs like that guy must have no chill whatsoever"
Then I heard that they were okay and I was like "He still got no chill"
Lol
+Dr Scrubbington ⟨InfinityV0rtex⟩ loll same
let's see if Matt Damon agrees
+Hopey Olguin I'm assuming you're referring to The Martian.. Well, that was on Mars, not in space. It's different.
***** You shut the fuck up. On Mars there's a ton of variables that makes it difference from space. For one, there's an atmosphere, so the subzero temperatures would likely kill you.
+GamePhysics he's talking about interstellar
martin h How do you know?
+turkanator123 SPOILER!! welp, that's one DVD I don't have to get anymore...
I was waiting for that Star Lord cameo!! haha
"So next time you're pushed into the vacuum of space..."
*dies
Dude I don't know if you're ever going to read this but that was perfectly explained with a lot of information in a short amount of time and a little bit of laughter. Thanks for uploading
I just wanted to know if what Chris Evans and the other guy did in the film Sunshine (2007) when they wrapped themselves with thermal insulation sheets and jumped off that abandoned space station to their station without bursting out was possible or not, and it seems yes..
StarLord and Spike Spiegal I'm lookin at you 2.
StarLord isn't fully human though-
Or DID he? Important questions!
Creatively -unsynced LET'S GO TO THE FILM
***** we will never know if he shit his pants ;) I though it was pretty realistic over all, also the timing seems to be quite scientifically correct
***** But they didn't in the movie. I think she passed out round about after 10 or 15 secs and he wasn't out without his mask much longer than that, so I think it was quite accurate.
How cool is this? Don't hold your breath, you'd poop your pants, get a terrible sunburn, pass out from lack of oxygen in 15 seconds, and if rescued within three minutes you'd probably survive. WAY less gruesome than I thought!
Oh, yeah, and it'd be intensely uncomfortable.
a science video with not only fascinating information, but the sources to back up the claims! thank you!
I agree with a lot of comments here... why dont we use death row inmates...
1. They would be contributing to humanity
2. We dont need to waste anymore tax money on these scumbags
3. Save the innocent dogs and monkeys
4. Get a lot more accurate data pertaining to effect on humans
I totally agree as well, but people will react so crazily. Different ethnicities will be like "Stop doing that to our society! It looks like we are protesting about this."
Slojanko Mastery You think it makes us more "human" by hurting innocent animals than violent criminals... Hmmm.... Interesting...
Slojanko Mastery I guess we can agree that we both have very different definition of what HUMANE is... for me at least, an honest loyal loving dog's life is more valuable than a violent inconsiderate monster calling himself a human.
Slojanko Mastery Bro, Nazi's killed innocent people, not criminals. Also, my point was not towards all people in jail. Its only those on death row. The convicted criminal lost the right when they committed the heinous crime.
I'm sorry to say this but I believe, a terrorist who kills innocent beings don't deserve to live and have "human rights".
+Abhishek Viswanatham
You are about as qualified to judge another human being, as a passed out chimpanzee in space is qualified to judge whether or not he is suffering from ebullism.
I feel sorry for all the poor animals humans experiment on.
Let humans experiment on you then.
Samething
I do too, but it's important for science and medical research. However, i do wish that they would take more ethical measures into handling the animals.
rain bow That is true and I do not like when they try makeup and stuff on animals. However for medicine and science yeah I will allow it.
rain bow They are probably handeled WAY better than the animals you eat next time you go to kfc or mc donalds
I like how Trace D explains things..!! He's awesome!
I have wanted to know this for so long. Thanks Trace
Holy cow humans are fragile.!
Hi Clark Kent!
Hi Bat Droid
Clark Kent you get fragile too when exposed to kriptonite so we all have weaknesses ones more than others.
TheMETALICA40 WHAT!? CLARK KENT IS SUPERMAN... I NEED TO TELL THE WORLD!!!
Bat Droid
that might not be good idea!!!
Here an interesting question
What would happen if you went into space without a spacesuit but you still had an O2 tank and a mask that wouldn't fly off your face from the pressure of the tank
Would you still die or would you just float around in extreme pain until the O2 runs out
+mewantbrains Eventually you would die from the trauma. Your skin can't regenerate itself fast enough, for one thing.
+mewantbrains I don't think you can breathe it in because there is no pressure in space.
+mewantbrains All your body fluids will boil.
Your blood won't boil
Scishow explained that
And in my example you can breathe
You have an O2 tank and a mask that won't immediately fly off your face
You wouldn't explode you dumbass
Your connective tissue is a lot stronger than you think
Excellent video, Trace; humorous and enlightening
hahaha, I always love how much enthusiasm Trace has xD
I wouldn't want to get sucked in by a planet.....
Thank god for earth's gravity pulling shit together.
What an amazing video this time! It was really interesting and I totally believed that you would explode if you were thrown out into empty space. I learned a lot today =D
This was a super interesting video!! More science-y videos like these; the videos just commenting on surveys are pretty dull
Would they need to have you in the pressure chamber for a few hours than the usual time? like when you come up to from a dive too quickly
well I think if you were sucked into the vacuum of space you already had the effects of depressurization. so it would pretty pointless to acclimate you again. the damage is already done.
So what if you went in space in scuba gear
Mustang Q Depends on what type of Scuba gear. If, for example, you're talking about an atmospheric diving suit, you would survive in space without any of the symptoms mentioned in the video for as long as your oxygen lasts and then you would asphyxiate. If you're talking merely about a breathing apparatus with an O2 tank, I have no clue....
+Bla Blablovski
yes and that s why astronauts uses scuba gear to go in space...
You wouldn't be protected because of the light material and your face must be completely covered
Damn, I love these kind of videos!
Great video. Great scientific story it answered one of my questions about space. Thanx
I wish I could fly naked in space for about 10 seconds.
😂😂😂
LOL
Have fun with shitting yourself at -270°C lol
Lol... You would have a scatological belt orbiting you
Humans have such strange fetishes!
Would it help if I had my towel with me?
Yea
That was awesome piece of information guys)) thx alot
this host guy is great. love his style.
My mom kept gasping behind me lol
maybe she was in space
atombot89 AHHAHHHAHAHHAHAH
so you die after 15 secound or 3 minutes? I didnt get that.
You pass out after 15 seconds due to lack of oxygen.
As for dying? Well... I don't think he mentioned exactly how long it would take but I would say maybe around 15 minutes?
But hey! You're passed out while the process is happening so don't worry about it. :)
It is that you passout in 15 secounds and die in 3 minutes
ImNotGenerous not like 3 minutes because your not breathing? i dont know anyone that has survived 15 min without breathing...
You lose consciousness after 15 seconds, and are likely dead after 3 or so minutes, though plenty of people have been clinically dead for more than three minutes and been resuscitated with no or minimal long term side effects. So pretty much just like drowning only more painful.
3 minutes you pass out at 15
Lol. I loved the way he said, "would your eyes pop out" 0:06
So Trace's been handling DNews single handed recently! good job man, I'm grateful for that :)
If you went into space with nothing but an O2 tank and regulator, and a pair of goggles, could you survive in space and be aware of what's going on?
Nope ur blood will boil
Morris Andersen so bring a pack of ice
Marius Stankevicius dude it wouldn't boil because of heat
Ah damn you scienc
William Oreos no it wouldn't
So constipated people should go out into space?
Lol it would be very painful though
It's really interesting to see the personality contrast between test tube trace and dnews trace....complete 180....
Wow thanks it's really helpful
I don't want to be an astronaut anymore...
Same lol
I'm dead....😂😂😭😭
rest in peace then
Why is there a spider?
implying you can get through van allen belt to begin with
C0pyPasta the van allen belt is not something like an "impenetrable wall"... or some shit... it's nothing you can touch. It doesn't stop you at all. Getting past it would be easy as shit. The difficulty would be withstanding the radiation. Tho, it's not really that difficult. Spacecrafts are well shielded against the radiation and the radiation isn't equally dangerous everywhere. There's some spots in the belt that are really thin, making the exposure of radiation really short term. Also, you don't even have to go past the van allen belt to be in space... Space starts waaaay earlier. You'd have to get past the van allen belt to reach the stuff like the moon or mars, but space starts earlier. the iss is orbiting the earth on low earth orbit, far away from the van allen belt. The ISS orbits earth at a distance of around 250 km, while the van ellen belt starts at 1000 km away from earth. think before you write retarded nonsense.
Imagine if people started doing this as entertainment: just jumping into space to experience the beauty of space and then being saved.
awesome video dude
I heard if you hold your breath in space your lung explodes. Is that true?
I'd have to say yes because like he said with the alveoli, the gases will get ripped directly from your lungs, even if it means tearing through your lungs into your bloodstream. That's why he said, if you notice you're going into a vacuum, make sure to exhale.
I'm sure it would. I'm scuba certified and one of the important things you learn is that you never hold your breath while diving. The reason is because if you start to swim up, the decrease in water pressure can cause the air to expand in your lungs. In some cases this expansion can cause death.
Spaaaaaaccce! (o)
This set is so much better than the current one
i don't understand why there are negative comments. his skill for speaking and explaining is very good. he wouldn't care about stupid opinions here though. i study English through watching this channel with fun. thank you for your excellent works!!
Why use animals for these experiments? They should use humans? And no I wouldn't volunteer. They should use people on death row. And don't tell me this is.inhuman. Using innocent animals is.
+Orlando Cruz well some humans helmets accidentally came loose while there were in a vacuum so that how they know what would happen for sure
+Erick Hernandez I know that in the name of science sacrificing innocent animals have led scientists to lots of good things like cures to horrible diseases. But as an animal lover it's hard to accept. I feel wrong for eating meat and struggle with it every time. I just wished we didn't have to kill animals or use them.
+Orlando Cruz I care about animals too but sometimes for you to protect other animals some of them need to be tested or sacrifice for the greater good because if they weren't we will never understand there illnesses or how they function, this is the sad part of life if for other too live, cruel things must be done for some of them
+Orlando Cruz oh yeah I know some people have trouble eating animals I don;t have that kindness like you
say your loved one is in their death row would you send them for these experiments?
Experiments on animals. Just sick
someone had to do it in those days we had no idea what could happen
better then testing on humans
WAAAAHHH SCIENTISTS R SO BAD, LETS GO BACK A HUNDRED YEARS WHERE PITTING ANIMALS AGAINST EACH OTHER WAS COOL, OR 2 THOUSAND AND MAKE LIONS FIGHT HUMANS. WAAAH IT WAS SO MUCH BETTER THEN!
Fucking jackass.
Because out there in nature those animals have a happy life with sunshine and rainbows and they never kill or brutally assault and rape each other noooooo, animal life in the wild is just like we imagine it from our children drawing books. /sarcasm
So
I bet going into space wearing a sealed helmet, shorts and a butplug will be a common thing in the future for those thrill seekers that nowadays do wingsuit flying and such.
If you really were in space, and someone in a space-suit did rescue you by, giving you some of their suit's air, you would still be unable to inhale. Air enters our lungs because the expansion of our thoracic cavity creates a difference in atmospheric pressure. The pressure in your body becomes less when you inhale and air is sucked into your lungs. So unless your rescuer, pumped the air from their suit into your mouth, he/she would experience trouble getting you to breath in.
twistedyogert
Or you know cpr, he could blow air into your lungs that way. ez pz
This is animal cruelty! Like if you agree that humans shouldn't put dogs and chimps in vacuum chambers.
lol
They are breakfast in China
+Yo Mama savage..
You should make more videos that are 5+ minutes long. I'd even watch for 10!
Though you've got to admit, watching Tim Robbins head explode in Mission To Mars was kind of awesome.
I love Trace!
Now I want to feel what's it's like to be in a vacuum.
No you don't.
a vacuum is nothing like the vacuum of space
Here's something I shouldn't mind you going into more detail of. Explosive decompression like explained 8:00 into this video. Or the movie DeepStar Six. Details like what happens to the body, what it must feel like and are you dead before you explode or what?
Cheddar is my favorite one, from all the types listed on his shirt.
I love Trace.
Fascinating. I assumed being exposed to the vacuum of space pretty much meant instant death. It's neat to consider there's a chance to survive after exposure.
Realy good information!!!!
I think this has to be the funniest D news episode so far :-)
Finally. I hated clearing this misconception for so many people.
This guy should prove empirically every assertion in this video.
I really enjoyed this.
Are there videos of animals? I looked for EXPERIMENTAL ANIMAL DECOMPRESSIONS TO A NEAR-VACUUM ENVIRONMENT and video but found you.
Wait, I read some paper that actually claimed that your blood would not boil, as the pressure of blood would prevent. Your veins would swell up, sure, but not to a point that the blood pressure would drop to levels where it can boil, assuming a temperature of 37 °C. Btw. it is degrees celsius, not just 37 Celsius, but 37 *degrees* Celsius.
Well, that was fun. Thanks!)
Quick/dumb question. If I managed to grab a breathing apparatus before being pushed out. Will using it to breathe help me last a little longer out there? Or is the speed of which the oxygen leaves my body too fast to hold anything in? Thanks.
Trace is so funny, I really like him on D-news
Not to worry, Trace. I'd totally be your Star Lord. Super interesting video!
Hi, great show.
I wonder if you were to escape the ISS equipped with a spacesuit, is it possible to get to earth alive, only using your spacesuit and the propulsion you get from kicking away from the ISS?
You would burn upon re-entering Earth's atmosphere
this was so interesting i feel like my life has been enriched
this was uploaded a day before my birthday
Hey trace you know how we see the curvature of the earth by the horizon. Would the horizon be further on bigger planets for example Venus, or if we could stand on it, Jupiter?
I like Trace. He can make even dying in space funny. And interesting of course.
This should be the new in-flight/ take off movie for astronauts. Just add a "the exits can be found here, here and here" and your good to go.
Just have/be in a working spacesuit. Or some real or imagined (but possible) way to breathe/function properly in space.
I'd like to see that information about the dogs at 0:55 is there a link
Question, is it possible to put air into a vacuous canister with out a lid? Like one air molecule at a time until it’s filled to the brim? That’s way there’s not pressure to expel it into space?
This was one of your more enjoyable episodes, but I can't tell if it is actually just elaborate native advertising for the movie you referenced. Do you get paid to mention 'Starlord"?
imagine getting launched into space,die, then 100's of years later other life forms bring you back to life with thier tech and remember everything .
Cohaagen's death in Total Recall is one of the most disturbing scenes I have ever seen in a movie (along with the cut spider nest scene in the original King Kong). Thank God that wouldn't actually happen.
Space is just to mind blowing 😦
Imagine if in the future people jumped into space with space suits on and then got rescues for fun like BASE jumping and stuff
awesome i guess things can adapt and evolve.. to live in such an atmosphere!...
This knowledge makes me slightly less terrified of being spaced.
Wouldn't smooth muscle tone be maintained by the autonomic nervous system? Thus negating the vasodialation in low pressure?
THIS WAS SO INFORMATIVE!!!!! KNOWLEDGE YAY!!!
Best video ever!
This guy is great!
Thank you for giving me anxiety nightmares, DNews. :/
"Dad, I'm in space!"
*"I'm proud of you son!"*
"Dad are you space?"
*"Yes, now we are a family again."*
How much time would you have before your heart stop ?
Well, that was a pleasant thought.
