We hardly ignore it, we just read it correctly, unlike you.

Collins et al. (1999) agree that the formation of the grooved terrain on Ganymede was likely the result of post-formation "global expansion".

Did you actually read the stuff you link to? The expansion phase was during a limited period when Ganymede was in its differentiation period, i.e. the creation of a metal core, a rocky mantle and an ice/water outer layer.

Clearly, they are talking about an epoch long long ago, no growing Earth theory for Ganymede.

Yes, and that is still going on, but the stretching does not come from a growing inside, it comes from tidal workings on the icy layer. For example, the cycloidal marks on Europa are now well explained by tidal flexing. This is the same process.

This is such a stupid comment, I can hardly believe you link to it. A growing Earth page, not really mainstream peer reviewed, but anywhooooo. Naturally, during the creation of the solar system the planets "grew" in that they obtained more mass through inelastic collisions in the primordial cloud. This is NOT expansion.

Dunno, where zou got the quote from Bland & Adam, but the next link has exactly NOTHING to do with an expanding Ganymede, but again with a the time of differrentiation. Naturally, there can be a time that the inner part expands because of extreme heating, which I guess would occur during differntiation.
You really need to come up with more convincing evidence that the Earth and the planets are expanding.
