* No central point: Unlike planets orbiting a star, there's no single, massive object at the center of the universe that galaxies revolve around. The universe is expanding, and galaxies are moving away from each other.
* Gravitational influence: Galaxies are held together by their own gravity, and they are influenced by the gravity of other galaxies in their vicinity. However, this influence doesn't create a neat, orbiting pattern.
* Large-scale structures: Galaxies are clustered in groups, clusters, and superclusters. These structures are shaped by gravity, and galaxies move within them in a complex, interconnected dance.
Think of it like this: Imagine a giant, expanding balloon with galaxies painted on its surface. As the balloon inflates, the galaxies move apart, but they also clump together in regions where the balloon's surface is stretched more tightly.
So, while galaxies don't orbit a central point, they are constantly in motion, influenced by the gravity of their neighbors and the overall expansion of the universe.
