Light is slow here
In this park, the speed of light is 5 kilometers per hour — a brisk walk. Just like in the real world, the speed of light is not attainable, only approachable asymptotically. The more you speed up, the more relativistic effects will become apparent: length contraction, time dilation, Terrell rotation, etc. The Doppler effect of light also becomes apparent, with objects in front of you blueshifted, objects behind you redshifted, and transverse Doppler effects visible on objects in motion.
