Show HN: What if the speed of light was 5 km/h?
20 days ago
- The simulation sets the speed of light to 5 km/h, making relativistic effects noticeable at walking pace.
- As you accelerate, you approach the speed of light asymptotically but can never reach it.
- Observed effects include length contraction, time dilation, and Terrell rotation.
- The Doppler effect is visible: objects ahead appear blueshifted, behind redshifted, and moving objects show transverse Doppler shifts.
- Controls: use W/A/S/D or arrows to accelerate, mouse to look, space to stop, and keys L/G/C/B toggle effects, R resets.
