Einstein protocol

Einstein protocol is a standard used for precisely measuring the distance between two objects in space. The Einstein protocol of finding the distance between two points is sending light from point a to point b and then immediately sending a signal, using light, from point b to point a. The calculations done with this data uses the formula $D = c {{t_3 - t_1} \over 2}$.

The protocol

Because there are many factors in measuring the distance of space a protocol was set up to determine order of importance when measuring a distance, using light, from a to b and back.

Footnotes

Because space is not linear we can attribute one factor to the curvature of space and time when light is sent from one area to the next.
