The Mass of the Universe

Our next question comes from Tim from Virginia. He was curious why all of the moons that I've ever heard of are rocky and there are no gas moons that exist or do they? Why and why not? That's the fundamental human question. Are you especially thirsty today? You want to drink a whole moon? You know put your straw up to it and just like shh. inhale a moon eat a moon drink a moon.
