The astronauts can throw up if they live in space



Hanging in space can make quite strange things to the human body, which is badly adapted to life without gravity. It can create a lot of health problems, keeping clean is a big problem, and making a wee is majorly difficult.

But is it true that a snap hat claims you can not burp?

This is the question a Twitter user sent to the former International Space Station (ISS) Commander Chris Hadfield late last week, and received a surprising answer: that's true, quite.

You can not burp in space – at least not like you do on earth.

"You can not burp in space because the air, food and liquids in the stomach are all floating together like clumsy bubbles" Hadfield replied to Twitter.

"If you bore, you throw up your mouth. Guess where was the trapped air going?"

Air can of course travel from the stomach and out through the mouth into space. But the problem is the lack of gravity. Here on earth, when you have gas captured in your stomach, it rises to the top because it's easier than the food and stomach dinner there.

In space, where there is no gravity, the gas does not rise to the top. It stays mixed with all the other things in the stomach – like the below video, an ISS experiment that involved putting a roaring tablet in colored water.

So, if the gas wants to get out of the mouth, it will bring other things. There is a kind of cross between a burp and a coil.

"When a burps in space, it's often a" wet burp "which means some liquid is expelled," said NASA engineer Robert Frost at Quora in 2016. "It's typically like acid reflux."

And in 2011, Charles Bourland, a consultant for the NASA Food Technology Commercial Space Center, noted that "if you live in space, it's usually wet because the liquid and gas do not differ in the stomach they do on earth."

This rather unpleasant experience has also been called a "bomit", which should give you an idea of ​​exactly how terrible it is. Imagine it happens in a space color.

There are additional problems. You do not necessarily want all the gas that goes out at the other end either. The space is a small, closed environment and can therefore be quite smelly.

In the 1960s, scientists conducted experiments to determine which spacecraft would produce at least speed, because – wait for it – flammable butt gas was thought to be a danger in a pressure cabin.

Obviously, beans and other high-blood foods such as cabbage and breasts were removed from the space flight menu, although green beans and broccoli are now included.

And there is actually air circulation on the ISS to keep astronauts from stifling on their own CO2 exhale, so the movements are moving away quickly.

If you finally go to space it was a driving astronaut who found a way to belch without bomiting. According to the book What's in space? by Ariel Waldman, NASA astronaut and physicist Jim Newman, who spent 43 days in space, developed what he called "push and burp".

"He found that by pushing a wall he could create a force instead of gravity that held food in his stomach and gave him a short chance of expelling gas without consistency," Waldman wrote.

The astronauts are really brilliant people.
