Spotlight on Original Technology – Radiation Band Testers
Two universes, two radiation bands. If you need to know who belongs where, you’d better do some testing.
In order to “sour the milk”, the energy signatures are changed to a different background radiation band. It is revealed that the band for our prime universe is twenty-one centimeters. This comes from a very real concept known as the Hydrogen Line.
In Parallels, Worf steps through several quantum realities (e. g. several universes), but eventually a quantum signature is matched and he can be returned to his correct universe. I have taken the ideas and combined them.
Here, There and Everywhere
If we are a twenty-one centimeter background radiation band universe, then surely there must be a twenty, a twenty-two, and so on. For my fanfiction, the twenty centimeter band universe is the mirror. The twenty-two, as is revealed by Eleanor Daniels in Where the Wind Comes Sweepin’ Down the Plain, is a place where, on Earth, the dinosaurs never died out. Hence a mirror-type situation could not develop there.
Radiation bands are inherited, and a cross-bred child will split the difference.
Hence the children of Doug and Lili and Doug and Melissa have a twenty and one-half centimeter band, reflecting his twenty and the women’s twenty-one centimeter bands. Per Eleanor, until crossovers became more common, a radiation band of anything below twenty-one was a sure sign that someone was one of Doug’s descendants.
Calafans, who can easily shuttle back and forth, and who have origins that are readily determined by the color of their skin (silver for here, copper for the mirror), are not tested, as there is no need.
Testing is accomplished in a few ways. During Temper, on the mirror side of things, the testers are table-top devices with wands. Eleanor is in possession of one (she is a docent at the Temporal Museum, with a specialty in the Terran Empire) and she demonstrates its use during Where the Wind Comes Sweeping Down the Plain. The image shown is actually a bar code scanner. Imagine it plugged into some sort of a tabletop device, possibly something appearing to be a lot like a personal computer or the like.
For our side of the pond, the scanner is a pendant worn around the neck, but devoid of any charm or decoration. The pendant is worn and then placed against a person, much like the mirror universe’s wand, so that a determination can be made as to which universe is the origination point for a particular person. The image at right is actually a UV tester. Imagine it attached to a longer cord and worn around the neck, although with the shorter cord it could conceivably be worn around the wrist.
While the eventual future of these testers is as a curio, their history is far from pleasant for, during the war between the universes in Temper, anyone with the wrong band, on either side of the pond, is often shot on sight, with no questions asked. This shameful heritage is meant to drive home more of the horror of the Mirror Universe.
