Galacticus is not a super hero; it’s a super model used to determine the formation and evolution of the galaxies. Developed by Andrew Benson, the George Ellery Hale Distinguished Scholar in Theoretical Astrophysics, it is one of the most advanced models of galaxy formation available.
Rather than building his model around observational data, Benson’s Galacticus relies on known laws of physics and the so-called N-body problem, which predicts the motions of celestial bodies that interact gravitationally in groups. Galacticus’ now an open- source model produces results as stunning 3-D videos.
Some 80% of the matter in the universe cannot be seen. This unseen
