Curved Space Models
Purpose
Three crocheted cloth models in CMB-inspired colors represent universes with positive, negative, and zero spatial curvature. Students handle the models to build intuition for non-Euclidean geometry and connect curvature to cosmological observations.
Figure 1:
The three models represent flat (zero curvature), hyperbolic (negative curvature), and spherical (positive curvature) geometries, corresponding to possible large-scale structures of the universe.
