The supermassive black hole known as Sagittarius A Star gives the spiral shape to our galaxy and keeps it together. Gravity is the force ensuring that “what goes into a black hole, stays in the black hole.”

All around us, gravity works in hidden ways. Gravity on a small scale keeps everything securely stuck to the surface of Planet Earth.

Except in my flying dreams. But I digress.

In writing, punctuation serves the same function as gravity, keeping paragraphs and sentences from flying apart, shaping prose. The physics that constrain the chaos of words and word clusters are the laws of grammar and punctuation. They are the quantum mechanics of writing.

What is spoken must be easily distinguished from the ordinary narrative. Therefore, punctuation is for the reader’s benefit. While we can take some liberties with grammar and dialect when writing conversations, following the established rules of punctuation is essential.
