“What food the stars eat, if they are animals:" 1d58 worldbuilding prompts from Adelard of Bath

Adelard of Bath lived in the twelfth century, studied Arabic science, and wrote down what he considered to be prize-winning scientific questions and his own best stab at them. These also make, incidentally, great worldbuilding prompts - they are, after all, something an intelligent person in a medieval milieu could look at and imagine different answers to, hence something where the completely bonkers metaphysics you just made up might produce something very similar to the taverns-and-sword-fights social reality that we all know and love to pretend at. Some of these are just fucking great ("what food the stars eat, if they are animals") some are most interesting for their look at how assumptions differ ("why women, if they are more frigid than men, are more wanton in desire") and some are rather small fry ("why those [animals] which ruminate lie down first on their hind legs and last on their forelegs.") Regardless, lest I impose my own assumptions about what is interesting too much, here is the full list, or at least the fullest version I could find:

1. Why plants are produced without the sowing of seed.
2. How some plants are called hot, since all are more of the earth than of fire.
3. How different plants grow in the same region.
4. Why they are not produced from water, air, or even from fire, as they are from the earth.
5. Why, when a plant is grafted, the fruit is that of the grafted part, not the trunk.
6. Why certain beasts chew the cud, and certain others not at all.
7. Why those which ruminate lie down first on their hind legs and last on their forelegs.
8. Why all animals which drink do not make water.
9. Why certain animals have a stomach, and others do not.
10. Why certain of them see more sharply by night than by day.
11. Whether beasts have souls.
12. Why men are not born with horns or other weapons.
13. Why those who have good intelligence are lacking in memory or vice versa.
14. Why the seats of imagination, reason, and memory are found in the brain.
    
15. Why the nose is located above the mouth.
16. Why men get bald in front.
17. Why we hear echoes.
18. How, as the voice comes to the ear, it may penetrate any obstacle.
19. What opinions should be held concerning vision.
20. Whether the visible spirit is substance or accident.
21. Why, as one can see from the darkness into the light, one cannot similarly see from the light into darkness.

26. Why the fingers were made unequal.
27. Why the palm is concave.
28. Why men cannot walk when they are born, as animals do.
29. Why men are nourished more by milk.
30. Why women, if they are more frigid than men, are more wanton in desire.
31. Why men universally die.
32. Why the living are afraid of dead bodies.
33. How or why the globe of the earth is held up in the middle of the air.

43. Why water does not go out of a full vessel open in the lower part, unless an opening is made above.
44. Whence the winds arise.
45. Whence the first movement of air proceeds.
46. Whether, if one atom is set in motion, all are set in motion, since whatever is moved moves something.
47. Why the wind does not move around the earth to the upper regions.
48. Where or whence such great impetus comes to it.
49. Where thunder comes from.
50. Where lighting comes from.
51. Why lightning does not come forth from all thunder.
52. By what power lightning penetrates stones and masses of metal.
53. Why, when we see the fire, we do not hear the crash, either at once or forever.
54. Why the planets and especially the sun do not keep their courses through the middle of the aplanon [outermost and immovable sphere of heaven] without revolution.
