Whether the rubber is stronger than metal or not is
not the issue, based on your description on the sea floor, both inside
volumes of balloon and can, are crushed.
to manage an empty pocket under the water, thus to
keep the water out of that space, you either need air pressure or mechanical
strengh to resist to the water pressure.
so how your design fits in between?

you have it right..

Hey EM,
Scary
because you are operating from a particular design perspective, but not the
only one.To demonstrate this, here's a question:
When is rubber
stronger than metal? Answer:
At the bottom of the ocean. Take a rubber
balloon and a soda can to the bottom of the sea and the balloon (though
smaller) is intact, yet the can is flattened. Why? Obviously because the
balloon was elastic and was able to shrink under the pressure. What I have
designed provides mechanical elasticity, not that the hull actually changes
shape, just how the pressure differential is interpreted. In theory, a paper
bag could withstand the pressures of the deep seas utilizing this process.
anyways, thanks for inquiring,
