The Slow Lane: Why We Need More Relativistic Reality Checks The latest brainchild from developer Dmitry Brant is a simulation called Relativity Park, where the speed of light has been slowed to 5 km/h (3.
11 miles per hour). This setting allows us to experience firsthand the visual and temporal distortions predicted by Einstein's general relativity.
While this may seem like a frivolous exercise in physics fantasy, it's actually a valuable tool for understanding one of the most profound concepts in modern science.
