​if Popper knew what a 4D ​hypersphere was (and he almost certainly didn't)
he would say the existence of such a thing was a untestable hypothesis and
the simplest explanation that fit the observable facts is the Earth is at
the center of a regular old 3D sphere with a 13.8 billion light year radius
and no fancy stuff is required. I would disagree.
