Metaphysical books about other worlds and how humankind survives on them?

Specifically, books with worlds that are conceptually so unique and different from our own that it leaves you thinking about it for days afterwards? And you get to see how the world shapes society.

Some examples of mine include:

The Inverted World Folding Beijing (novella, but still interesting) The Long Earth Nightfall (either the book or the novella) Dark Matter Virtual Mode

Also - I forget which book this is specifically but I love the concept of a story that takes place on a tidally locked planet. And lastly - honestly the planet next to the black hole in Interstellar blew my mind and I’d love to read a book that expands on a similar concept.
