A phenomenon is hereby noted in that particular bodies with a small gravitational pull (<= ~3.49 kg.) exhibit a greatly elevated Sleep Field. Those within the reach of this field (that is, within the Sleepschild Radius) will also fall asleep, while small, faster-moving bodies outside the Radius remain largely unaffected. Once a large body within the Sleepschild Radius goes dormant, the radius can be observed to expand almost exponentially, from the normal 0.75–1.5 meters to several tens of meters, sometimes claiming all orbiting bodies within a local system, although some researchers theorize that larger bodies outside the Radius will cause other, smaller, faster-moving bodies to go dormant before they go dormant themselves. Of further interest is the so called Alpaca Blanket Theory, which greatly increases the effects of the Sleep Field within a 3 m2 area.
