While scientists admit that they really don't know about two important factors in the development of galaxies in the universe, namely dark matter and dark energy, evolution is left behind a much easier to inspect historical crime scene.

When we look beyond our own galaxy we are still surprised by what we find. Galaxies too light to be held together, galaxies accelerating away from each other.
