What is "jigglings"

Usage examples of "jigglings".

Random jigglings triggered a collapse of the dustcloud, with everything heading for roughly, but not exactly, the same central point.

All it takes to start such a collapse is a concentration of matter some­where, whose gravity then pulls more matter towards it: random jigglings will produce such a concentration if you wait long enough.

A fresh pie was moving jerkily through the air toward the window, and its hesitations and jigglings corresponded exactly to the old man's gestures.
