But we have many times.  Michelson-Morley, Michelson-Gale, Sagnac, Airy, Hubble's red shift showing we occupy pretty much dead center in the universe, the Cosmic Microwave Background on three occasions (which produced 'the Axis of Evil' also showing we occupy the center of the universe).  These tests have been repeated numerous times all with the same result - no movement of the earth.  The bible also happens to state this. 

What's really amazing is how 'science' got around the MM experiments - the machine had to be physically shrinking (yep) at just the exact rate to make it show the earth wasn't moving.  Amazing indeed.  Einstein popped out Relativity and the rest is history.

I do think God is predictable though and if the planets appear as spheres then earth should appear as a sphere.

The video I posted in #23 and #55 shows how math shows that the earth curves.  Please view it and let me know your thoughts. 

False dichotomy.  The Ptolemaic/geocentric model of the solar system, does not exclude the possibility of flat land.

The Almagest ([color=var(--color-progressive,#36c)]/ˈælmədʒɛst/[/iurl][/font][/size][/color] [color=var(--color-progressive,#36c)]AL-mə-jest[/color]) is a 2nd-century [color=var(--color-progressive,#36c)]mathematical[/color] and [color=var(--color-progressive,#36c)]astronomical[/color] treatise on the apparent motions of the [color=var(--color-progressive,#36c)]stars[/color] and [color=var(--color-progressive,#36c)]planetary[/color] paths, written by [color=var(--color-progressive,#36c)]Claudius Ptolemy[/color] (c. AD 100 – c. 170) in [color=var(--color-progressive,#36c)]Koine Greek[/color].^{[color=var(--color-progressive,#36c)][1][/iurl][/font][/size][/color]} One of the most influential scientific texts in history, it canonized a [color=var(--color-progressive,#36c)]geocentric model[/color] of the [color=var(--color-progressive,#36c)]Universe[/color] that was accepted for more than 1,200 years from its origin in Hellenistic [color=var(--color-progressive,#36c)]Alexandria[/color], in the medieval [color=var(--color-progressive,#36c)]Byzantine[/color] and [color=var(--color-progressive,#36c)]Islamic[/color] worlds, and in Western Europe through the [color=var(--color-progressive,#36c)]Middle Ages[/color] and early [color=var(--color-progressive,#36c)]Renaissance[/color] until [color=var(--color-progressive,#36c)]Copernicus[/color].

Book I contains an outline of [color=var(--color-progressive,#36c)]Aristotle[/color]'s cosmology: on the spherical form of the heavens, with the spherical Earth lying motionless as the center, with the [color=var(--color-progressive,#36c)]fixed stars[/color] and the various [color=var(--color-progressive,#36c)]planets[/color] revolving around the Earth.

I watched that when it was posted in #23.  What I find interesting about all of this is that there is actually enough for both sides to go on.  One can say 'the math proves it' but then flat earthers have record breaking line-of-site tests, laser tests over 25 miles of open water, engineering and government works all using a flat based system, etc. 

Another thing I was wondering about was a biblical firmament and then some guy posted a video of him reading from a 1956 US Encyclopedia saying the Firmament was detected in Antarctica around 13,000 feet.  Pretty strange world out there.

Cecco was burned at the stake for his globe earth cosmology

Having published a commentary on the Sphere of [color=var(--color-progressive,#36c)]John de Sacrobosco[/color], in which he propounded audacious theories concerning the employment and agency of demons, he got into difficulties with the clerical party, and was condemned in 1324 to certain fasts and prayers, and to the payment of a fine of seventy crowns. To elude this sentence he went to [color=var(--color-progressive,#36c)]Florence[/color], where he was attached to the household of 
Carlo de Calabria. His pseudo-science and plain speaking had made him many enemies; he had attacked the Commedia of Dante, and the Canzone d'amore of [color=var(--color-progressive,#36c)]Guido Cavalcanti[/color].^{[color=var(--color-progressive,#36c)][1][/iurl][/font][/size][/color]} The physician [color=var(--color-progressive,#36c)]Dino del Garbo[/color] was indefatigable in pursuit of him; and the old accusation of impiety being renewed, Cecco was again tried and sentenced for relapse into heresy. He was burned at Florence the day after the sentence, in his seventieth year.

Show me the science that supports that.  If the land was flat and presents like a pizza, what is the diameter of Earth?
