Okay...
The heretics did the job for me:
http://www.ethicalatheist.com/docs/flat_earth_myth_ch5.htmlhttps://en.wikipedia.org/wiki/Flat_Earth#Early_Christian_ChurchNotice that when for example Saint Augustine and others regard the idea of antipode being ridiculous you have to conclude that he believed in a flat Earth or a spherical Earth but in a completely different way than modern belief, that means regarded gravity as ridiculous idea (it is). Read St Augustine below for a understanding of the spherical earth idea that some had.
St. Augustine
“As to the fable that there are Antipodes, that is to say, men on the opposite side of the earth, where the sun rises when it sets on us, men who walk with their feet opposite ours, there is no reason for believing it. Those who affirm it do not claim to possess any actual information; they merely conjecture that, since the earth is suspended within the concavity of the heavens, and there is as much room on the one side of it as on the other, therefore the part which is beneath cannot be void of human inhabitants. They fail to notice that, even should it be believed or demonstrated that the world is round or spherical in form, it does not follow that the part of the earth opposite to us is not completely covered with water, or that any conjectured dry land there should be inhabited by men. For Scripture, which confirms the truth of its historical statements by the accomplishment of its prophecies, teaches not falsehood; and it is too absurd to say that some men might have set sail from this side and, traversing the immense expanse of ocean, have propagated there a race of human beings descended from that one first man.
St Boniface
"As for the perverse and sinful doctrine which he (Virgil) against God and his own soul has uttered—if it shall be clearly established that he professes belief in another world and other men existing beneath the earth, or in (another) sun and moon there, thou art to hold a council, deprive him of his sacerdotal rank, and expel him from the Church."
Saint Basil (implying that he saw contradictions to the presented Ball earth of the Greeks that is ours now)
“Moses, is silent as to shapes; he has not said that the earth is a hundred and eighty thousand furlongs in circuмference; he has not measured into what extent of air its shadow projects itself whilst the sun revolves around it, nor stated how this shadow, casting itself upon the moon, produces eclipses. He has passed over in silence, as useless, all that is unimportant for us. Shall I then prefer foolish wisdom to the oracles of the Holy Spirit? Shall I not rather exalt Him who, not wishing to fill our minds with these vanities, has regulated all the economy of Scripture in view of the edification and the making perfect of our souls?”
St. John Chrysostom (cited by Kosmas)
“Where are those who say that the heaven is in motion? Where are those who think it is spherical? For both these opinions are here swept away.”
Anyways if you people are claiming to be scientific show me the proofs.
As I said the only possible way is electromagnetism.
The moment physics and mathematics are detached from engineering and geometry this is the only possible result.
