Generally, the cloak also diffuses or masks the electromagnetic signatures of the object so that you ship knows the general but not precise location. However, the anomaly effect still clearly shows up on the sensor reading but the science officer rarely thinks to aim at the center of it.

# Cryogenics is depicted simply as lowering the person's body temperature to freezing temperature. People in cryostasis simply look like people sleeping in an empty refrigerated tube. [[note]]In reality, preparations for cryo-suspension include such things as removing the blood and replacing it with an anti-freeze sailine solution. Also, the body (as well as internal organs) must be submerged in a glycerine-like solution that prevents the water in the rest of your cells from crystallizing. This same solution must be pumped into all of the body cavities to ensure cell coverage and equalize pressure inside and outside the body. All of these things ensure eventual revival to be a tedious, involved, multistep process, not simply opening the tube to awaken the sleeper. It also ensures that cryonic suspension for humans will remain legal only for those declared clinically dead.[[/note]]
# The modern Gregorian calendar is the default mode of navigation in time travel.
# Constellations are used as reference points in space, even by aliens visiting Earth who might say that they are from a planet in the Lynx Constellation, despite the fact that they don't see any of the same constellation star patterns from their native star system.
