Now I see what you meant earlier...
Those panels in the detailed picture, they are supposed to be the heat resistant shield, the shield, right. That would have been the more correct answer.
It looks really resistant, doesn't it...
Makes me wonder, how could we, humans, have been so stupid all that time, as to believe their crap!?

I can answer one of your questions.
Theory of gravity. The theory of gravity is a theory, that's all it is. 😉
Assuming this planet is a sphere, it seems as if stuff is pulled towards the core. Which is why big bodies of water are curved.
Density is a good one. It's a word I can comprehend. 😁
It's dense here. Higher densities are much less dense. It's all too solid here.
Free energy works with photons and magnetism.
Electro-static would be lightning I guess. Lightning bolts, those are big doses of electro-static force.

Reality seems to be getting less dense lately.
