Corollary III – Gravity of Earth

Where were you when I laid the foundation of the earth?
Tell me, if you have understanding.
Who determined its measurements—surely you know!
Or who stretched the line upon it?
On what were its bases sunk,
or who laid its cornerstone,
when the morning stars sang together
and all the sons of God shouted for joy?

(Job 38:4-7) ESV

Gravity is measured by dropping things. If we accurately time how quickly an object falls to the ground we can get a measure of its acceleration due to gravity. This is denoted by the symbol g.

This gives us a way to measure and compare the strength of gravity in different places. The strength of gravity on Earth is variable but only one thing has any effect on it:

Gravity decreases with altitude as one rises above the Earth’s surface because of a greater distance from the Earth’s center.

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

Matty’s Razor

The Newton/Einstein popular science paradigm is based on the idea that mass is the cause of gravity. In this model every particle in the Earth is contributing to its gravitational pull which we measure as g. We’re proposing that gravity is actually a field emitted from a singularity at the center of the Earth which imparts attractive force to all particles within the field. This is still measured as g. The empirical observations are the same. Variation in g is based on distance from the center of the Earth.

The difference is profound but it’s a simple matter of resolving the practical application of math with our frame of reference.

1. Earth is the center of gravity of the observable universe:
• this is an empirical observation,
• it’s congruent with all practical applications of math.
2. Earth is a minuscule speck of gravity in a universe which has no center:
• this is theoretical (imaginary),
• it’s incongruent with the practical application of math.

In case you were wondering, today’s image is of Sir Isaac Newton’s apple tree.
