RequirementsĪ Slower Speed of Light has been tested on computers with the configurations listed below. Intended for game developers, educators, and anyone interested in physics, OpenRelativity can help people create, test, and share experiments to explore the effects of special relativity. A Slower Speed of Light combines accessible gameplay and a fantasy setting with theoretical and computational physics research to deliver an engaging and pedagogically rich experience.ĭownload our PowerPoint presentation about the relativistic effects in the game: PPT PPTX OpenRelativityĪ Slower Speed of Light was created using OpenRelativity, an open-source toolkit for the Unity game development environment. Players can choose to share their mastery and experience of the game through Twitter. These effects, rendered in realtime 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) and the runtime effect (the ability to see objects as they were in the past, due to the travel time of light). Visual effects of special relativity gradually become apparent to the player, increasing the challenge of gameplay.

Custom-built, open-source relativistic graphics code allows the speed of light in the game to approach the player’s own maximum walking speed. A Slower Speed of Light is a first-person game prototype in which players navigate a 3D space while picking up orbs that reduce the speed of light in increments.
