    Iā€™ve heard a theory that thereā€™s solid metallic hydrogen at the core from the absolutely immense pressure, but it hasnā€™t been confirmed.

      Jupiter would have certainly had countless rocky, icy, and any other category of asteroid fall into it over the last several billions of years, so itā€™s not all hydrogen.

      And Iā€™m not sure if solid is the right word. Itā€™s denser than solids weā€™re used to, but itā€™s not necessarily making any bonds between nearby atoms, so they might flow to some degree.

      Though even if is solid at some point, it wonā€™t necessarily be a sudden change from gas to solid or even gas to liquid to solid. The pressure is so high it might be more of a gradient than a surface like weā€™re used to here.

        Hereā€™s what I was taking about. The idea is under the right temps and pressures youā€™d get a lattice of single hydrogen atoms instead of hydrogen atom pairs. It could potentially be meta stable after being produced, but thatā€™s still to be determined.
