I was reading the question asked here in regards the Alexander Gerst's patching of a small (5mm) hole with his thumb temporarily. This got me wondering, if his thumb was only fine because the majority of it was part of the ISS atmosphere, at what point would it not be okay to do this?
Two main scenarios come to mind that have me intrigued:
Ignoring that the hull is likely too thick to support either of these scenarios...
If the hole were the size of his finger-tip and he plugged it such that the entirety of his finger-tip was through the hole, would the results be different? Would his finger tip sustain more damage?
What about simply sticking your thumb through a hole that was created for a thumb to be stuck through it, with a perfect seal between the interior and the exterior of the ISS?
Alternatively, more simply put, where would the damage stop? At the hull interior?
Is the thickness of the hull the only thing that saved him from damage-- the fact that he wasn't actually "outside" of the ISS "atmosphere" at any point?
Looking for the limitations in this question. What would happen over the course of:
- 5 minutes?
- 1 hour?
- 10 days?
- As much time as it needed to fuse you to the hull?
- Where would it stop, would it?
