Scul you are making this too complex. This is a lot simpler. First of all the earth cannot be rectangle. Its either sphere or flat circle. Any other shape leaves no room for our current navigation. Only sphere or flat circle can make east west navigation around the earth possible. Although space travel has not been proven, circumnavigation of the earth has, so the earth cannot be anything but sphere or flat circle. I think its flat circle. I respect your theories although I still do not get it. It seems like you are mixing a lot of things together. Angels, Anunaki Atlanteans Gods. Its not that complex man. There either is space or not space. Either flat circle or spherical.
Unfortunately the truth is a lot harder to understand then Sphere vs Circle because reality is neither are nor can be correct because if Earth was a Circle then it would appear as an Oval from outer-space due to the way light was hitting it. If Earth was a sphere you wouldn't see it slant upward to an average of 133 degrees nor would you see the hulls of ships fade before the mast as due to the sheer size of the Earth it would appear almost completely flat to our perception but that is quite obviously not the case.
I don't know if I told you about the Telescopes but if you go out to see and watch a ship fade from the Hull to the Mast you can then use a telescope and the ship will "straighten" out to your line of sight. This is because the hull of the ship disappears from view faster then the mast because the mast has greater illumination then the hull. A lighthouse can be seen from a distance of typically 12-16 miles before fading but with a high powered telescope can be viewed from 400 miles away or more. Granted even if Earth was a Globe it would only dip 1 Degree every 81 miles which even over 400 miles would only be 5 degrees of viewing distance shift downwards to an average man that would translate to about a 162 feet drop which the Average ship is about 175-200 feet tall and the average ship can only see around 1.2 miles before small objects fade.
20 feet square object
Feet From Viewer / Viewing Percentile
10 feet / 90%
20 feet / 45%
30 feet / 30%
40 feet / 22.5%
80 feet / 11.25%
160 feet / 6.125%
320 feet / 3.0625%
640 feet / 1.56125%
1280 feet / 3 Degrees
2560 feet / 1 Degree
5280 feet / .78 Degrees
6761 feet / .5 Degrees
Less then .5 degrees is impossible to pick up from Light Deflection alone for greater distances to be seen you must either A: Have a high powered telescope or B: Be looking at an illuminated target.
150 Feet Tall Lighthouse for example would be in Vertical distance
150 feet away / 45%
300 feet away / 22.5%
600 feet away / 5.625%
2400 feet away / 1.4%
4800 feet away / 2 degrees
9600 feet away / 1 Degree
19600 feet away / .7 Degrees
27740 feet away / .5 Degrees / Fade Distance
So about 5.2 Miles the Lighthouse should fade due to optical distance yet the light illuminated from within gives the lighthouse 3 times the penetration distance as light always travels in 3 directions and increases it's optical footprint 3 times therefore the 5.2 mile lighthouse becomes and 15.6 Mile lighthouse.
However if you use a 50 degree magnification telescope you are going to get increased distances.
27740 feet away / 50.5 Degrees
55480 Feet away / 25.25 Degrees
110960 Feet away / 12.125 Degrees
443840 Feet Away / 3.03 Degrees
1775360 Feet Away /.75 Degrees
2690780 Feet Away / .5 Degrees.
509 Miles = 1527 Miles of Viewing distance, however telescope magnification always looses optical range due to subsurface scattering therefore your eyes can see objects at .5 degrees yet a telescope only picks up objects that are 2 degrees or greater. Thus 1527 miles is cut down to 381 Miles of viewing optical range.
