PASSENGER GUIDE
WARNING: Read This Guide Before Boarding the Redshift.
The environment aboard a hyperspace craft is quite safe as long as you are careful. The management reminds you that the speed of light on board this craft is ten meters per second, or about 30 million times slower than what you are used to. This means you will frequently encounter relativistic effects and optical illusions.
NEVER TAMPER WITH YOUR LIFEBELT OR ATTEMPT TO UNFASTEN IT. THE FIELD IT GENERATES ALLOWS YOUR NEURAL TRANSMISSIONS TO OPERATE AT NORMAL SPEEDS AND IT IS ABSOLUTELY ESSENTIAL TO YOUR HEALTH.
1. Use only the ship's master clock displays. Do not rely on your personal timepiece; it will accurately record your personal subjective time, but it will never agree with any other timepieces until you reset it when you leave the ship.
2. Remember that everything you see and hear is at least slightly in the past, due to the time it takes sound and light to travel. The closest things to you are the most current.
3. Trust what your hands tell you rather than believing your eyes. Bending light can make you think a convex floor is concave. Colors may shift and shapes may distort.
4. Go slow. Limit your speed to a fast walk until you are familiar with the environment. Please heed the traffic rules. By running fast, it is possible to exceed the speed of sound, which is only 6.7 meters per second.
5. Never assume anything.
6. Have a nice trip.
