This GeoGebra applet demonstrates a 3D universe model. By utilizing commands such as Point, Sphere, and PointIn, it constructs a 3D geometric structure containing multiple spatial points and spherical surfaces. The model can be used to illustrate geometric relationships in 3D space, the distribution of celestial positions, or the relative positions of points and spheres in solid geometry, helping
