We all know light travels very fast. But what if it traveled at human walking pace? A new game from the MIT Game Lab, called A Slower Speed of Light, shows just what would happen if light decelerated to this speed.
The game itself is fairly simple: collect 100 orbs. For each orb you pick up, though, light slows incrementally, and the visual effects of special relativity gradually become apparent. These effects, rendered in real time to vertex accuracy, include:
- the Doppler effect (red- and blue-shifting of visible light and the shifting of infrared and ultraviolet light into the visible spectrum)
- the searchlight effect (increased brightness in the direction of travel)
- time dilation (differences in the perceived passage of time from the player and the outside world)
- Lorentz transformation (warping of space at near-light speeds)
- the runtime effect (the ability to see objects as they were in the past, due to the travel time of light)
