About the Author
I love science as much as art, logic as deeply as emotion.
I write the softest human stories beneath the hardest sci-fi.
May words bridge us to kindred spirits across the world.

Take the solar system as an example.
The rotation of the Sun distorts the spacetime of the solar system, leaving behind traces in the cosmos that resemble folds and creases.
The planets travel along their respective folds, which are their orbits—and in this motion, they possess both revolution and rotation.
Why, then, does the Sun rotate?
The answer lies in an even grander structure of spacetime: the Milky Way.
It is the rotation of the entire Milky Way that distorts the spacetime of the galaxy.
Every subsystem within its domain is affected without exception, and the rotation of the Sun arises precisely from this.
