The best way to write about emptiness

The world is full of empty space, and it’s often hard to describe. The world is generally empty, so we need better ways to describe it. Try arguing for the best way to write about absolutely nothing. Argue for words, statements, and writing styles that get the idea across best. Write about how to get emptiness across professionally vs. casually. Writing about emptiness simply vs. describing ever aspect.
(this is still a pretty rough idea)
