Pondering other worlds, whether those be the distant worlds in our own universe, or the worlds we can enter through the stories of others.
...
Speaking of which, here are some worlds/stories that I like, in no particular pattern or order (though this is probably in need of some updating):
The Cosmere
Avatar: The Last Airbender
The Legend of Zelda
The Xenoblade Chronicles series
Ender's Game, Speaker for the Dead, and adjacent books
Project Hail Mary
The Remembrance of Earth's Past
Dune
Interstellar
Arrival
Inception
Tenet
Princess Mononoke
Castle in the Sky
Fullmetal Alchemist
Star Wars
...And probably a bunch of others I'm forgetting. This list is not comprehensive.
I can ice skate now! It only took me three separate stake youth activities separated by a year each!
And I feel slighted, because my eleven year old sister was able to do it within five seconds of stepping on the ice. Because she knows how to roller skate.
