September 12th

Circumferential Shortening

The earth is violently broken, The earth is split open, The earth is shaken exceedingly. The earth shall reel to and fro like a drunkard, And shall totter like a hut; Its transgression shall be heavy upon it, And it will fall, and not rise again.

(Isaiah 24:19-20) NKJV

It appears from the amount of subduction and upthrust around the world that the Earth’s circumference has changed. It’s an arcane phenomenon called circumferential shortening.

On September 9th we saw that seismic waves give us a way to investigate the internal structure of the Earth, and that they confirm the presence of a great gulf of open space between the mantle and the core which Jesus spoke of in Luke 16:26.

On September 10th we considered the possibility that geological features such as Monument Valley, Utah, and Pilot Mountain, North Carolina, are remnants of the pillars of the Earth. We also gave an approximation of the radius of the Earth on the third day and the thickness of the mantle.

We all have the same evidence. Our choice of paradigm determines what we think it’s evidence of.

Matty’s Razor

We (that’s me and the Holy spirit) have to know the end from the beginning and the beginning from the end. We know that the crust of the Earth is made of tectonic plates. We also know that at some time in the past these plates moved so much, so fast, that the collision caused mountain ranges, like the Himalayas, and deep ocean trenches to form.

Circumferential shortening is a change in the circumference of the Earth, evident from tectonic plates, deep ocean trenches and up thrust mountain ranges. Caused by Radial Shrinkage.

– Circumferential Shortening, definition

In the early days of Geology people would do arcane things like measure the amount of crustal material that was overlain, subducted or upthrust into mountain ranges and conclude that there’s too much of it. Why’s there so much extra crustal material to account for? This is known as circumferential shortening and it used to vex Geologists of yesteryear. Some proposed radial shrinkage, that the radius of the Earth must have shrunk, but no one was ever able to satisfactorily explain why the Earth underwent radial shrinkage and the issue faded out of view.

This is not something that you hear much about these days but Geologists of old used to wring their hands over calculations of circumferential shortening and how to account for it. In Matty’s Paradigm circumferential shortening is accounted for by radial shrinkage. We can make some calculations of how much circumferential shortening there was if we know the volume of the Earth’s mantle. Using the information from seismic waves, and our hypothesis about the pillars of the Earth, we have a simple calculation to deduce what the Earth’s radius was at the end of the third day of creation.

Calculating Circumferential Shortening using 2πr

RadiusSymbol2xπr= (km)
Radius of 3rd Day Earthtr23.14 x 7,65348,085
Radius of Present Day Earthpr23.14 x 6,37140,030
– Change in Earth’s circumference is approx. 8,055 km

At the tectonic breakup of Pangaea the Earth underwent radial shrinkage and circumferential shortening. Earth lost 1,282 km of radius and 8,055 km of circumference.

  1. Call upon the name of Jesus Christ,
    • believe in your heart that God raised him from the dead,
  2. confess your sin.
