putting fingers in holes
You are currently reading a thread in /sci/ - Science & Math
Me and my friends argued after watching one of the alien movie where the alien get its head emptied in space through a very small opening in the space station.
now we both agreed that since the difference in pressure is 1 atmosphere between the inside and the outside of the space station, and that the hole is very small, it couldn't actually empty the guy and was more or less harmless.
The actual argument was about wether sticking your finger in the plug the hole was dangerous or not. sure, it's almost a perfect vacuum outside and your finger would swell up, but wouldn't the blood keep flowing because the rest of your body is safe, , and the worst case scenario would be that while swelling up your finger would get stuck in the hole and need to be cut ?
TL;DR : if you stick your finger in a gap between a space station and space, would you actually have long lasting problems , a fucked up finger or nothing at all ?
There would just be some suction. Your finger would be fine.

You could compare this to Delta P diving accidents. The pressures there far exceed 1 bar and yet the divers are just held in place and not shredded up or something.
You're working against pretty low forces here so I think you'd be able to just pull the finger out.
Brings me back to grandads old fingerbox

Man, when was the last time I played with a fingerbox? Pic related, was the one I used when I was a kid.
the one variable here - we dont know the physical composition of the alien baby
human fingers are designed to be sturdy - reinforced with bone, plenty of structural tissue, and covered in a dense layer of elastic protein to reduce abrasive damage
an alien baby would probably be more insectile than mammalian, with a tough protein coat over a hydrostatic interior. but, as a newborn, it probably hasnt been exposed to atmosphere and its outer skin hasnt hardened yet - hence why it appears yellowish rather than the traditional black. some parts of it will be stiff in order to facilitate movement, but it doesnt have the rigidity of a fully grown being
think of it this way: instead of a finger, imagine putting a stretchy, water-filled balloon against a hole against vacuum

You can make more low pressure using your mouth sucking on dick than a hole out into space. This is because the air pressure is only 1atm going out to 0atm. That's not much at all. It isn't like a compressed bottle of liquid propane or your garage air compressor tank.
You get a big hickey and the longer you stay there the worse it will get until you start bleeding out through your skin. That will take quite a while though. Like hours and hours.

Delta P accidents are vastly different since it involves pressure far beyond 1atm. So yeah, a small hole out into space wouldn't be a problem. In fact, you may save everyone by sticking your finger into it until it can be properly patched.

Could be all gelatin-like, fur sure. I think its main problem is the acidic blood making the hole even larger.
