Light.

Light is at the center of the galaxy.

Stars and planets revolve around the Light.

There is no center to the Universe.

The universal center is everywhere.

So we only have the model of the galaxy.

And, as with the Solar System, Light is at the center.

This symbolizes the Reality that God is at the center of everything.

And God is everywhere.

The Light shines and is not diminished.

When stars die new stars are born.

This is the eternal cycle of Life. 

And if gravity is Love then everything is bound by Love.

For God is Love.

And Love leads us to the Light.
