* The Sun doesn't "go" anywhere in the traditional sense. It's a star, and stars are massive balls of gas that generate their own light and heat. They stay in one place relative to their local space.
* The Sun does move in relation to other things. For example:
* Our solar system orbits the center of the Milky Way Galaxy. This is a very slow journey, taking about 225 million years to complete one orbit.
* The Milky Way Galaxy itself is also moving through space.
So, while the Sun doesn't move quickly in a straight line across the universe, it is constantly in motion relative to other objects in space.
