👉 A non-shrinking, or non-rotating, set of points in space is a geometric concept that represents an idealized state where all points are fixed and do not move. In other words, it's a configuration where no point can be moved to another position without changing the total distance between them. Non-shrinking sets have many applications in mathematics, physics, and computer science. For example, they are fundamental in understanding the behavior of the universe's largest known structure, the black
