I can draw a model of the earth and the moon which explains (and predicts) full moons, no moon, the moon visible during the day, and lunar eclipses. I challenge you to do the same
Dr. Samuel Birley Rowbotham could mathematically and accurately predict lunar eclipses and its phases. Consult
Chapter 11 of Earth Not a Globe and scroll to the bottom.
All of Astronomy is based on the assumption of the Earth as a Globe. How do you think Astronomers got the Astronomical Unit? I'll tell you:
Each astronomer throughout history make accurate measurements in relation to the distance of the Earth and Sun by using triangulation between two distant points on Earth, observing the Sun and measuring the angles in relation to the sea-level of the Earth. An astronomer could either triangulate the Sun's distance from the Earth to 93 million miles
or 3,000 miles. It entirely depends on whether the earth appears as flat or round in the author's triangulation equations.
It is impossible to judge a celestial distance by looking at a distant Sun through a telescope alone. The triangulation equations require two different observers who are separated far enough away so that the angles of the Sun and Venus are slightly different. It is necessary in triangulation to require two known points in space. Look at how GPS works.
For example,
this link shows us how modern Round Earth science calculated the distance between the Earth and Sun using the transit of Venus. You will immediately notice that the equations are highly dependent on the assumption of a Round Earth.
If we take those same triangulation equations and use them under the assumption of a Flat Earth and do away with the compensation extrapolation for the curvature of the Earth, assuming a flat surface, the final equation for the distance between the Earth and Sun becomes
rT = (PT / PV)2/3 (1 - eT cos ET) / (1 - eV cos Ev)
When we plug in the numbers from that link, the figure 'rT', the distance between the Earth and Sun, is equated out to an approximation close to 3,000 miles.
Finally, the angular size of the sun is 0.5°. Using this fact with a distance to the sun of 3000 miles, gives the sun's diameter: 32 miles.
Do you see now how the entire cosmos is drastically affected by an assumption?
No, I wouldn't. I value piece of mind over monetary gains. If you think money buys happiness you are a fool.
If you blindly and dogmatically follow the opinions and beliefs of others, then you are the fool. Sorry to say.
