Topic: Galaxies Like Grains of Sand in New Herschel Image

Astronomers using the European Space Agency's Herschel telescope have discovered that the brightest galaxies tend to be in the busiest parts of the Universe. This crucial piece of information will enable theorists to fix up their theories of galaxy formation.

What an awesome picture.  Every point of light is an individual galaxy containing billions of stars.  My questiion is:  "why is the Universe so prolific?"  Most of us are dumbstruck with  the galaxy in which we live.

There's a lot of "stuff" in that picture

And that's only the baryonic stuff we can actually see.  80% of matter is invisible and cannot be detected by telescopes of any type.
