Granted. The definition of a mile is now 1/60th of the distance travelled by light in an hour.
This is already the case, as matter travels through time and space at the speed of light. The speed of light is the only speed, the only variable is how much of that speed is used in space or time.
1.) I wish the speed of light were 60 MPH.
2.) I wish nothing could travel slower than light.
3.) I wish for the genie’s freedom.
