We are confusing two things, impact strength and strength with respect
to uniform force. For resistance to uneven force the flat surface is
weaker. But for resistance to uniform force an infinitely large flat
surface should be strong. The force of gravity is constant and always
perpendicular to the surface, and there is no weakest point. There
is no center to sag and collapse.
Look at a surf board. They are very light and strong, and the skin is
quite thin. With the foam interior they are rather like a watermelon.

No, but I have 15 years of melon planet experience. Mostly
Cannonballs, a few cantelopes and an experimental gourd project.
Hen's eggs are 28th century.

I'm inclined to believe it, but then why does the ocean get colder as
one descends, while earth grows hotter?
