## What is Galaxy Formation?

Galaxy Formation is a multi-platform educational app depicting how dark matter particles in the universe clump together over billions of years to form things like stars, planets and galaxies. The app does this with a lite, real-time simulation of thousands of n-body particles that are attracted by gravitational forces that form galaxies when combined.

## Key features

- Real-time n-body particle simulation
- Gravitational force interaction
- Formation of stars, planets, and galaxies
- Multi-platform educational tool
- Visualizes cosmic evolution
