🧪 N-Body Galaxy Formation with Dark Matter Halo

Explore the complex process of galaxy formation through our N-body simulation, where you can directly manipulate gravitational forces acting on a simulated collection of stars and dark matter. Observe how these interactions shape galactic structures over billions of years, mirroring real astronomical phenomena. The dark matter slider now strengthens gravitational binding between bodies in real time, showing how an unseen mass halo holds a galaxy together.
