Wait please; you've jumped from
expansion to
mass accretion. I'm still studying expansion. Excuse my pace- I'm trying to work at the same time.
From your links (the ones I could open), and other sources on this wonderful internet, I get
heating as the dominant mechanism for expansion, most likely
tidal heating, or
radiogenic heating, or a combination of both. This seems acceptable to me.
3. Are you ok with this?
I also find that from the interaction, distribution and physical properties of craters and groves, that Ganymede expansion was a) relatively small and b) a long time in the past. This also seems acceptable to me.
4. Are you ok with this?
Lastly, my Q1 again:
1. Is there a difference (amongst scientists) between
peer-reviewed and
mainstream thought?
Thanks
