What's Next

You have implemented the foundational equations of cosmology. Here are natural next steps:

  • General Relativity — The Friedmann equations are solutions to Einstein's field equations. GR gives the geometric foundation for everything in this course.
  • Particle Physics — Big Bang nucleosynthesis, the matter-antimatter asymmetry, and the nature of dark matter are all particle physics questions.
  • Observational Cosmology — The Planck satellite, SDSS galaxy surveys, and gravitational wave detectors are testing these equations with exquisite precision.
