The cosmos' hidden scaffolding

Computer simulations show the weblike pattern that matter follows in our universe.
RELATED TOPICS: COSMOLOGY
Filaments-of-dark-matter
In September’s article “Astronomers reveal the universe’s hidden structure,” author Steve Nadis described the scaffolding of invisible material — called dark matter — that forms the filamentary structure of the cosmos. Normal matter — like stars and gas — makes up only about 15 percent of the universe’s mass; this material follows the weblike distribution of dark matter.
