Among competing hypotheses, the one with the fewest assumptions should be selected. - William of Ockham (c. 1287–1347)
"And therefore as it is possible, that in the remote regions of the fixed stars, or perhaps far beyond them, there may be some body absolutely at rest; but impossible to know..." Sir Isaac Newton speculating about the firmament.
We can deduce that the firmament, a rigid sphere of crystal on the edge of space which has been detected by the Voyager and New Horizons space missions, shines as brightly as the sun by comparing two passages.
When we change our assumption from Heliocentric to Geocentrospheric it has an effect on the distance to stellar objects. This is because of the way that stellar parallax works.
Relative motion is a difficult concept to teach most people. They're convinced that the success of space missions and the ability to land a space craft on a comet proves heliocentricity.
The best illustration of how we can switch back and forth between different frames of reference, such as heliocentric and Geocentrospheric, is an interactive guide to the flight path of the Voyagers.
Bible study is our meat and potatoes at Matty's Paradigm, it's what we do. Daily Bible reading is also really important and many of our insights have come from simply following a routine.
We can convert heliocentric planetary mass values to Geocentrospheric using Matty's Constant, 9.87^-12, for the conversion of fantasy into reality.
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.
Newton's bold guess was that gravity is a property of mass. However, the proportional relationship between mass and gravity only measures the observed effect of gravity, it doesn't reveal its cause.
