– How do gas giants not have a surface? Where do asteroids and comets go when they get sucked in? What’s at the center of a gas giant?

Question

This has always baffled me. I can’t really understand how they could just not have a surface no matter how far down you go. Obviously gravity has to pull the gasses together into some more dense form eventually… right?
