- Relativistic Physics: Objects near light speed show time dilation, blue-shift glow, and velocity-dependent effects
- Tidal Forces: Visualize gravitational stress and Roche limit warnings for bodies at risk of breakup
- 3D Lighting: Realistic shadows, specular highlights, and day/night hemisphere illumination
- Atmospheric Effects: Stellar coronas, planetary halos, and sunrise/sunset scattering
- Custom Bodies: Tap-to-place mode with drag repositioning and color controls
