spherical Earth

The understanding and integration of the spacetime geometry constitutes an intellectual challenge for humanity comparable to that at the time which led to the spherical geometry of the Earth, with all the paradoxes that it entails for common sense:

-There will be places where it rains upwards

-Going away in one direction and without deviating, we will arrive back from the other side

-Where does the water of the seas from the bottom flow to?

-There will be beings who have their feet on the head (antipodal)

-Where remains the supernatural world?

Currently, these paradoxes seem to us almost childish, because we received a continuous instruction on the geometric model of the globe, but without using a model it would be a much more complex task (a sphere, for example, can be described by formulas of spherical trigonometry, but that would not be useful to understand, for example, the seasons of the year, the different climates, the voyages of the discoverers, etc.

Similarly, we hope that some day the issues and paradoxes of spacetime geometry, highly relevant to understanding the present world, will be seen as something very easy, using a geometric approach. These pages are intended to contribute in that way.
