Slow light is a dramatic reduction in the group velocity of light, not the phase velocity. Slow light effects are not due to abnormally large refractive indices, as will be explained below. The simplest picture of light given by classical physics is of a wave or disturbance in the electromagnetic field.
If you travelled a year at 95% the speed of light; you'd age one year, and people on Earth would age 3.2 years! But if you were going 50% the speed of light it would only be 1.15 years. The effect ...

OpenRelativity is a toolkit designed for use with the proprietary Unity game engine. It was developed by MIT Game Lab during the development of A Slower Speed of Light. The toolkit allows for the accurate simulation of a 3D environment when light is slowed down. [7] It is hosted on GitHub and has been published under the permissive MIT license. [2]
In the following, the notation of Mansouri–Sexl is used. [2] They chose the coefficients a, b, d, e of the following transformation between reference frames: = + = = = where T, X, Y, Z are the Cartesian coordinates measured in a postulated preferred frame (in which the speed of light c is isotropic), and t, x, y, z are the coordinates measured in a frame moving in the +X direction (with the ...
However, those experiments cannot directly establish the isotropy of the one-way speed of light since it has been shown that slow clock-transport, the laws of motion, and the way inertial reference frames are defined already involve the assumption of isotropic one-way speeds and thus, are equally conventional. [4]
The newly released fast neutrons, moving at roughly 10% of the speed of light, must be slowed down or "moderated", typically to speeds of a few kilometres per second, if they are to be likely to cause further fission in neighbouring 235 U nuclei and hence continue the chain reaction. This speed occurs at temperatures in the few hundred Celsius ...
