What's Next

You have implemented the core equations of special relativity. Here are natural next steps:

  • General Relativity — Curved spacetime, the Einstein field equations, black holes, and gravitational waves.
  • Quantum Field Theory — Combining special relativity with quantum mechanics gives the Standard Model.
  • Particle Physics — Every calculation at the LHC uses relativistic kinematics and the energy-momentum relation you built.
  • Electrodynamics — Maxwell's equations are automatically Lorentz-covariant; special relativity is hidden in classical EM.
