In their non-Euclidean geometry the part is always greater than the whole.

The history of non-Euclidean geometry has been aptly divided by Felix Klein into three very distinct periods.

Some years before, during the second half of the XIX century, mathematicians saw the birth of non-Euclidean Geometries.
Higher-Order Theories of Gravitation
We then extend the classical ring model to this case and show that its natural framework is the non-Euclidean hyperbolic geometry.

General relativity extended to non-Riemannian space-time geometry
Given that we have found that a ﬁnite temperature characterizes the quantum geometry with non-zero mass, it would be desirable to continue to the Euclidean theory to implement the ﬁnite temperature partition function as a path integral in Euclidean quantum gravity.
Newtonian gravity in loop quantum gravity
However, in the non-Euclidean geometry one succeeds to agree properties of different fundamental quantities not always.
Monistic conception of geometry
