comment Where does the extra kinetic energy come from in a gravitational slingshot?
The answer seems too long and not well structured to me (like a wall of text). Also, while it contains the key point - the answer to the subject of the question: Where does the energy come from? - It comes from the planet, it is not highlighted, it is hidden in the middle of the answer.

comment Why wet is dark?
This explanation cannot be possibly true for the sand or soil - no fibers to bend on it.

comment Why wet is dark?
The answer sounds plausible, however there is one thing which is still unclear to me: why when the wet surfaces freezes it turns bright again (often even brighter than before)? Refraction index of ice is more or less the same as for water. Perhaps the the ice not filling the space in between the grains as liquid water did?

comment Why does the air flow faster over the top of an airfoil?
As the accepted answer (and the wikipedia animation) shows, it flows even faster than equal-time condition would suggest.

comment Is apparent horizon curvature lesser due to refraction of light in the atmosphere?
I understand your reply as: refraction makes Earth to appear 15 % larger (cf. mintaka.sdsu.edu/GF/explain/atmos_refr/dip.html), and the apparent curvature is affected accordingly. Can you confirm this is what you meant? That would make sense to me.
