** Arthur Clarke's "The Wall of Darkness" (short story)

Description of life in a strange alternate universe where a single sun shines on a single planet of sentient beings, & where time behaves in a weird way. I didn't find it unreadable, but the core technical concept of the story escaped me.

Fact sheet.
