WebHence the flatness ‘problem’. Many attempts have been made to explain the flatness problem, and modern theories now include the idea of inflation which predicts the observed flatness of the Universe. However, not all scientists have accepted inflation, and the matter remains a subject of much debate and research.

This page explains how to do this, as well as the advantages and …
WebJan 21, 2024 · If you add these together you get 0.3965. Your result for flatness is 0.3973. It appears your results match with less than a micron of difference between the two. That difference can be accounted for based on Calypso calculating flatness at the edges of the plane and not only where your points are taken. WebFlatness is often described as being “the 2D version of straightness”. A straightness requirement applies to a 1D (linear) surface trace or axis in 3D space, whereas a flatness requirement applies to a 2D (planar) surface in 3D space.
