Gravitational Effects Concept

Demonstrations in Gravitational Effects

Three crocheted fabric models in variegated blue and green yarn: a flat disk (zero curvature), a ruffled hyperbolic surface (negative curvature), and a dome-shaped spherical cap (positive curvature)

Curved Space Models

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 …

Euler's Disk: The Sound of Colliding Neutron Stars

A spinning Euler's disk produces a rising-pitch "chirp" as friction dissipates its energy — strikingly similar to the gravitational wave signal from merging neutron stars. Students hear how energy loss …
