Reply to comment by dickbutt_md in Have you ever thought about what it sounds on jupiter by Western_Home6746

There is a sentence in that article that says “While some theorize that the core is a hot molten ball of liquid, other research indicates that it could be a solid rock 14 to 18 times the mass of the Earth” referring to the core

Would “solid rock” not mean a solid surface in this context?

Over which is an ocean of hypercompressed hydrogen at essentially the same density as the rock below.

The only transition is one of composition (mumble: and both seismic speeds) rather than density - which we seen in the terrestrial oceans.

So if it’s as dense as rock can you walk on it or is that not how it works?

We can walk on things because they're rigid solids.

But I doubt that there's a nicely defined discontinuity between the metallic hydrogen ocean and some rock.

The surface of a gas giant is defined separately from the core, as the article says: "...there is no solid ground, the surface of Jupiter is defined as the point where the atmospheric pressure is equal to that of Earth."
