Taming The Infinite/ Chapter 15/ Rubber Sheet Geometry.
We seem to be growing to greater levels of geometrical shapes, very inconceivable to be honest in that it gets harder and harder to understand, reasonably this is so because we have not the capacity to perceive anything beyond the third dimension, not even the fourth being it time. These new shapes seem to inevitable be surpassing these human limitations of perception, and therefore things get harder to conceive and of course to explain. Theories such as Hawkings and his imaginary space requires the considerations of these new kinds of geometry, a more "flexible" geometry that is. In short, it has given us the ability to invent and innovate, new worlds i.e. theories of space.
