If one wanted to have a wall between vacuum and .15 Oxygen atm (or 1

1. With "1 thin metal wall", you get some stretching of metal then
puncture with no sealing. Or is this wrong?

No stretching, it's too fast an event, you just get vapourisation of the
metal, and a hole/crater punched, depending on the size.

2. With "super-stretchable film" might one get long tube of stretched
film then puncture, so somehow the tube seals itself either by being
flatly pressed against remaining air by pressure or due to
self-adhesion?? I know its hard to get stretching due to super-speed
of meteor but possible at all??

No.
Basically, you can't get stretching unless the incoming impulse is several
times less than the speed f sound in the material.

3. With film that doesn't stretch but is "multi-layer" film or metal
walls lying next to dozens of other layers, if one allowed layers to
shift might not the layers post-strike shift to seal and avoid complete
path to space??? Layers shouldn't stretch, which would block any
shifting. I know hard to imagine layers of material any of which could
be pressure wall, but maybe imagine metal tubes inside each other slide
on top of each other while heated so later contract and pressurize
(this idea is getting complicated...)

And sounds heavy.

4. Is there some goop that could be put in between layers or maybe put
in "goop-bags" like bubblewrap that any meteor would go through and
thus immediately apply to any puncture, thus sealing it (so don't try
to fight meteor with this wall, use thin wall and then patch
afterward). Of course goop-bags would block transparent walls.

You then have to figure out something that won't leak out of the hole too.
5. Finally, how about using "floating goo-balls" that would be sucked
to hole to space and plug the leak, maybe in splat-ball shells to keep
goo-balls from sticking??? Use many floaters or a few big rubber
balls, to minimize time?


This will complicate ventilation - you don't want the balls going into
filters, ...
You need to insulate the hull.
If you don't, you get severe condensation on the inside of the hull,
and stuff growing in that moisture, which is bad for several reasons.
You need this insulation on the outside anyway, so it's not that big
a stretch to add some debris barrier layers.

Any sort of floating system means also that you can't bolt anything to
walls.
