Hi to All,
concerning the universe extension is it possible to assume that the
maximum distance between two points in the Universe is
3.14*13.7billion light years?

The Universe did not expand from a point outward in a spherical
fashion. This is fallacious thinking and has nothing to do with Big
Bang theory.

Also, the expansion of space is not constrained by light speed.
Therefore the Universe can be much larger in extent than its age, and
galaxies have relative separation velocities that exceed the speed of
light.
