[Physics] Would a submarine float in the atmosphere of Jupiter


Would a submarine float in the atmosphere of Jupiter, or would it get crushed?

Best Answer

As the comments above indicate, factors like density, pressure and temperature are important for a Jupiter submariner. Of course nobody yet has the exact details of Jupiter's interior structure, but there's a diagram in this LASP page[WebCite archived version] that indicates the following: At the intersection of Jupiter's liquid hydrogen/metallic hydrogen layer, the density is about $1\text{ g}/\text{cm}^3$, which would permit the submarine to float. However, the temperature there is $\sim5000\text{ K}$, and the pressure is $\sim2 \times 10^6\text{ bar}$, so it can't be done with normal equipment.
