The December sky is dense with constellations--the Great Bear, the Little Dipper with its North Star, Cassiopeia, Orion, Gemini--whose figures in Greek, Arabic, Norse, and Native myths walk the sparkling Spirit Path above our heads.

Where are they all going, and we with them? To the black hole at the center of our galaxy, through a forest of Dark Matter, to a quantum physics oblivion; to Bethlehem?
