Blowing my mind that Gas Giants are just big ole balloons
It’s an inside out balloon! Gravity holds the atmosphere in, not a cloth sheet
And I have a hard time believing that there isn't some solid or liquid (or maybe some other exotic state of matter, due to the heat and pressure) inner core way down in there, even if it's relatively tiny compared to the size of the planet.
Even if it was entirely made of gas when it formed, surely some materials would have fallen in over the eons that could stay solid/liquid at the pressure/temperature of a gas giant's core?
