10 STRANGEST THINGS IN SPACE (You Won’t Believe #1…)

[00:00:08][crying] >> All [clears throat] right, let's start with the most important scientific question of our time.

[00:00:14]What happens if you fart in a space suit?

[00:00:17]Sounds like a joke, but this is a real engineering problem that NASA actually thinks about. The suit is completely sealed, no ventilation to the outside.

[00:00:27]There's an air filtration system, but it won't save you from the smell. You're doing a space walk for 6 to 8 hours.

[00:00:34]That whole time, just you and yourself, literally. That's why astronauts follow a strict diet before any space walk. No beans, no cabbage, no carbonated drinks.

[00:00:47]That's not a joke. It's an actual item in the mission prep manual. Welcome to the channel. Today, 10 of the strangest things that happened to humans in space.

[00:00:57]If that first one got you, hit subscribe. It only gets weirder, and more terrifying from here. Let's go.

[00:01:06]What if you die on the ISS?

[00:01:17]NASA has no official protocol for an astronaut dying in orbit. None. No document, no procedure.

[00:01:26]The official answer?

[00:01:28]We'll figure it out.

[00:01:30]Unofficially, the body would probably be sealed in a space suit and strapped somewhere out of the way.

[00:01:36]Now imagine, you're on the ISS. 1 month until you go home. Your crewmate just died. You wake up, have breakfast, run scientific experiments, go to sleep next to a body every day for a month.

[00:01:55]>> [sighs] >> Astronauts don't talk about this publicly, but they definitely think about it. What if you explode a bomb in open space?

[00:02:11]No sound at all. There's an explosion, flash of light, radiation, debris flying in every direction, but no shock wave because there's nothing for the wave to travel through. Vacuum. Sound is the vibration of air. No air, no sound.

[00:02:27]That's it. Now the really interesting part. This isn't theory. The US and USSR actually detonated nuclear bombs in space in the 1960s.

[00:02:38]One American test, called Starfish Prime, created an artificial aurora borealis visible from Hawaii. People walked outside and stared at the sky with no idea what was happening. The blast also knocked out several satellites, including the world's first commercial communication satellite.

[00:02:57]After that, everyone sat down and signed a treaty banning nuclear tests in space.

[00:03:02]Good call. What if you pee in open space?

[00:03:08]It instantly boils and evaporates. Not from heat because there's no pressure.

[00:03:13]At zero pressure, liquids boil at any temperature, instantly. You'd get a cloud of steam around you. Probably looks beautiful, not very [snorts] practical though. Now here's a bonus, a real story. Early Soviet space suits weren't designed for long missions, no bathroom at all. Cosmonauts literally went inside the suit. Yuri Gagarin, the first human in space, asked the bus driver to stop on the way to the launch pad so he could pee on the rear wheel.

[00:03:38]That became a tradition. Every Russian cosmonaut before a Soyuz launch pees on the wheel of the same bus in honor of Gagarin. Some traditions are timeless.

[00:03:47]What if you throw up in zero gravity?

[00:03:55]About 70% of astronauts experience vomiting in their first days in orbit.

[00:04:00]70%.

[00:04:02]The brain gets conflicting signals. Eyes say one thing, inner ear says another.

[00:04:07]Result? Nausea. In zero gravity, vomit doesn't fall down. It flies forward right in front of your face. It forms floating balls which you have to catch with a cloth before they hit the equipment. The first American to experience this was John Glenn, a legend of space exploration, a hero catching floating vomit with a napkin.

[00:04:34]Apparently, the worst part isn't the smell. It's watching the balls slowly drift toward you and having nowhere to go. Zero gravity is beautiful. What if you fall asleep drifting in open space?

[00:04:48]>> [music] >> You wouldn't freeze immediately. Vacuum is a bad conductor of heat. Your body loses it slowly. First, you'd lose consciousness from oxygen deprivation in about 15 minutes. Then silence. And then, your body would drift forever.

[00:05:08]>> [music] >> In a vacuum, there's no friction, no resistance, nothing to slow you down or stop you. Billions of years from now, [music] you'd either get pulled into a star or flung by gravity beyond the edge of the galaxy. You'd become an intergalactic object, one of the very few man-made things outside the Milky Way.

[00:05:30]>> [music] >> Sounds like a bad ending. But, on the other hand, you'd go where no human has ever been. What if you sneeze inside your helmet?

[00:05:43]You can't scratch your nose, can't wipe your face, your hands won't fit inside.

[00:05:48]The helmet is sealed. You sneezed.

[00:05:50]Everything that came out is now on the inside of your visor, right in front of your eyes, and you can do absolutely nothing about it. NASA solved this with elegant engineering. Inside the helmet, at nose level, there's a small foam pad.

[00:06:05]Want to scratch your nose? You rub your face against it like a cat on the corner of a couch. This is a real design feature of the space suit. NASA engineers worked on it for years, years, so an astronaut could scratch their nose. Science is serious business. What if you play guitar in open space?

[00:06:28]The strings would vibrate, your fingers would work, the body of the guitar would resonate. You wouldn't hear a single note. Sound is the vibration of air. In a vacuum, there's no air. The instrument works, no music. But here's the thing, if you press the guitar against your helmet, sound would travel through the solid material straight into your skull bones. You'd hear something, muffled, strange, nothing like music, but something. That's roughly how deaf people experience music when they press their hand against a speaker. There's actually a guitar on the ISS. Astronauts bring it up. They play inside the station. Chris Hadfield recorded a cover of David Bowie right on the ISS. It went viral worldwide. Space loves music. It just can't hear it from the outside.

[00:07:17]What if you pour water in open space?

[00:07:25]It instantly boils. Not from heat because there's no pressure. Pressure is what keeps liquid liquid. Remove the pressure and water boils at any temperature, instantly. You'd get a cloud of steam and tiny ice crystals at the same time. Some of it evaporates, some freezes. It looks incredible. NASA filmed experiments like this. Look them up. Absolutely worth it. Now the scary part. The same thing would happen to the blood inside your body without a suit.

[00:07:54]Your blood would boil. But your skin holds pressure long enough. You'd die from oxygen deprivation before that happened. Space makes sure you go quickly. What if you light a candle in zero gravity?

[00:08:08]There will be fire, just not the kind you're used to. On Earth, flame is elongated because hot air is lighter than cold air and rises upward. The flame stretches toward up. In zero gravity, there is no up. Hot air spreads equally in every direction. The flame becomes a perfect blue sphere.

[00:08:26]Beautiful and slightly unsettling. NASA actually ran these experiments and discovered something important. A spherical flame burns far more efficiently and cleanly than regular fire. Less soot, more complete combustion. This is now being studied to develop better engines and fuel combustion systems here on Earth. A candle in space and new technology for all of humanity. That's how science works.
