| 説明 | Illustration of Olbers' Paradox. As you look further into the forest, the tree trunks will have a smaller angular size, but you will see more of them in the your field of view, so these two effects exactly balance to fill your field of view with tree trunks with no gaps to see out beyond the forest (which is either infinite in extent, or at least "large enough" that you can't see its extent).
