It is probable that both Jupiter and Saturn have cores of solid metallic hydrogen.?

I think it's false as it is liquid, not solid, correct?

    Metallic hydrogen exists, there have been a few lab experiments to try and create metastable metallic hydrogen however they couldn't get the metallic hydrogen to remain stable.

    Wiki Quote: " It may be possible to produce substantial quantities of metallic hydrogen for practical purposes.[citation needed] The existence has been theorized[citation needed] of a form called "Metastable Metallic Hydrogen", (abbreviated MSMH) which would not immediately revert to ordinary hydrogen upon the release of pressure.

    In addition, MSMH would make an efficient fuel itself and also a clean one, with only water as an end product. (if burned in pure oxygen). Nine times as dense as standard hydrogen, it would give off considerable energy when reverting to standard hydrogen. Burned more quickly, it could be a propellant with up to five times the efficiency of liquid H2/O2, the current Space Shuttle fuel. Unfortunately, the above-mentioned Lawrence Livermore experiments produced metallic hydrogen too briefly to determine whether or not metastability is possible. "

    It's very probable that there's a LAYER of metallic hydrogen around the liquid and solid iron cores of both Jupiter and Saturn. If there is enough pressure in the core of the Earth to make very hot iron/nickel/sulfur solid, then there is certainly enough pressure on Jupiter, which has 80,000 times the mass of the Earth, to make a layer BOTH liquid and metallic hydrogen. Since all of the planets and some of the dwarf planets underwent chemical differentiation so that atoms with higher atomic wights and specific gravities settle to form the cores of planets with enough mass to be spherical, it makes no sense AT ALL for a massive planet with a strong magnetic field that can only be created by iron, to have a core of an element with the least atomic weight on the periodic table.

    No it wouldn't be solid
