Has-been scientists with spandex. These are washed up university lecturers who like to impress young girls and boys with how cool they are, while promoting an untestable hypothesis like it’s real science.
Kepler's Laws are the weakest point of the theoretical foundation of popular science (SciPop). The weakness is that Kepler's laws are derived empirically, but they're applied theoretically.
Gravity was created on the second day. A gravitational singularity was created in the midst of the deep. At that time the universe became spherical. This is why space is curved.
The traditional battle lines of science vs. faith is a false dichotomy. Popular science (SciPop) can’t be the opposite of faith because SciPop requires faith.
When Einstein said that "space is curved" he was stating the fact that it's spherical with Earth at the center. Then he went off the deep end trying to prove that it wasn't, but he knew the obvious truth.
