Sounds right up my neck of the universe. I love that swirling drone space
music. It's also an interesting title and theme for the music.
In a previous life I studied clusters of galaxies. Coma is one of the
richness known but is atypical. It's a bit like a city but most congregations
of galaxies are in poor clusters and groups like towns and villages.
Carrying on the analogy, the populations and vistas are different too. The
smaller country clusters have more beautiful and inspiring spiral galaxies,
whereas the likes of Coma city are dominated by elliptical galaxies, the
largest of which gobble up small companions.
The brilliant Fritz Zwicky discovered dark matter as we would call it now
by observing that the motions of Coma's member galaxies implied much
more mass in the cluster than could be seen.
