Can you elaborate?
Or is this a pun about wave particle collapse;)
“Planar geometry is sometimes called flat or Euclidean geometry. The geometry on a sphere is an example of a spherical or elliptic geometry. Another kind of non-Euclidean geometry is hyperbolic geometry. Spherical and hyperbolic geometries do not satisfy the parallel postulate.” https://math.hmc.edu/funfacts/spherical-geometry/
