## The Field Value for Acceleration due to Gravity, g

In popular science (SciPop) the mass of the Earth is calculated by knowing: its radius, the gravitational constant big G, little g, the field value for acceleration due to gravity.

## Planetary Mass Values

Here's the table of planetary mass values in the Geocentrospheric cosmological model.

## Matty’s Constant

We can convert heliocentric planetary mass values to Geocentrospheric using Matty's Constant, 9.87^-12, for the conversion of fantasy into reality.

## 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 Mass of the Earth

The mass of the Earth has never been directly measured. It's calculated using the radius of the Earth, the value of g we get from a ball drop experiment (acceleration due to gravity), and the gravitational constant, G.

## Circumferential Shortening

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.

## Earth Internal Region Zone Volume Values

We have developed a 3D spherical hollow Earth model (SHEM). If the Earth has experienced radial shrinkage and it's diameter decreased, we can so some simple calculations to figure out what the original radius was.
