300 Foxes and a Donkey's Jawbone
We talk about the firmament as a sphere of rigid crystal on the edge of space. Popular science's (SciPop) second cousin astronomy exists for the express purpose of making it seem as if the presence of a firmament is impossible.
The Bible is God's Word. The Bible describes creation. According to the Bible a firmament was created in the midst of the deep to separate waters above from waters below. It's the beginning of a doctrine of gravity.
The windows of heaven are described in scripture as physical structures which may be opened or closed. This is possible because the firmament is a sphere of rigid crystal on the edge of space.
Nearly 4 billion miles from Earth, NASA's New Horizons spacecraft has detected evidence of a glowing wall of hydrogen at the edge of the solar system.
Outer darkness is only referred to three times in scripture, but by using context we can establish what and where it is. The easiest thing to take for context is the gnashing of teeth, which occurs nine times in the Bible.
As it speeds away from the Sun, the New Horizons mission may be approaching a “wall.”
Understanding relative motion is the power to comprehend that heliocentric and Geocentrospheric models coexist. The Geocentrospheric model is empirical. The heliocentric model is theoretical.
SciPop (the atheist human origins narrative) is an inductive rationalization of the premise that the universe doesn't require a divine origin. All evidence of the supernatural has to be rationalized as something else.
The Voyager spacecraft have been on their missions since 1977 and have flown far past the orbits of the planets in our solar system. They took a solar system family portrait and found the firmament.
