When asteroids approach the Earth they're at perigeon. You've heard of perihelion, we need a new word. We're going to coin a word to express the concept of perihelion, but proximity to the Earth (geo), not the sun.

Elliptical vs. Cardioid
We need to know that some concepts are paradigm-dependent. This means that they only apply after accepting the premise of a paradigm. We've been discussing elliptical planetary orbits, that's a heliocentric concept.
The Distance to the Firmament
The distance to the firmament (heaven), from the center of the Earth, is approx. 1,736,441 light years. But we (that's me and the Holy spirit) would appreciate it if someone would check our math.
The ISS isn’t Zero-G
If Earth is the center of gravity of the observable universe, then the observable universe is in the gravitational field of Earth. The strength of the field is inversely proportional to the square of the distance from Earth.
A Pavement of Sapphire Stone
You may be uncomfortable with the idea that God uses a section of the firmament as a movable platform like a giant cosmic surfboard. We get it, this is a deep end and we went off it. It's what we do.
Riding the Heavens
God and the heavenly host may visit the Earth on a section of the firmament, described in Exodus 24:10 as a paved work of sapphire stone. This gives us a Biblical basis for the Silver Surfer.
Foundations of Sapphires
The firmament was originally composed of many more layers than it is now. One layer in the midst transformed into something like obsidian, completely black, and melted causing the inner layers to separate.
The Brightness of the Firmament
The creation of gravity and formation of the firmament was to establish a place, heaven, where God would dwell in perpetual light because the firmament is bright like the sun, as we see from Daniel.
The Waters Above
The firmament, third heaven, originally had a portion of the deep covering its outer surface. At the time of Noah's flood the windows of heaven opened and the water poured through and flooded the Earth.
The Three Heavens
Given that the apostle Paul specifically refers to something called the third heaven it's not a stretch to conclude that there must also be a first and a second heaven. We need to know what they are.
