Have we ever sent anything into the atmosphere of the gas giants?

[GKDAIR]

I've often heard there's no solid ground in the gas giants, but do we know this for a fact or are we just guessing based off the math?

The Galileo spacecraft released a probe that parachuted into Jupiter. It was destroyed by pressure long before it hit the "ground", if a "ground" even exists.

It is unfair to call the math a "guess".

Wait, what?

Wait, what?

Something you didn't understand?

My understanding is that as you progress downwards through the atmosphere, under the increasing pressure, the atmosphere (mainly Hydrogen), gradually tends to become liquefied and eventually take takes the form of a solid metallic hydrogen. Beneath that, and probably mixed with it to an extent is probably a rocky core. Jupiter is continually receiving hits from meteoritic debris, rocky and metallic. This presumably, plunges down, slowing in velocity as it encounters the increasing viscosity of the atmosphere, and ends up on the surface of, and mixed with the solid hydrogen.
