If they don’t have a solid core, where do they create their gravity to hold all the gasses into a planet shape? I’ve never understood this.
In: Physics
Things don’t need to be “solid” in order to have mass, and mass is what generates gravity.
Further, the gas giants actually *do* have solid cores (sort of; it kind of depends on what you mean by “solid”) in that their cores are really really strange forms of hydrogen.
