Let me ask you guys a question. At one point in time, do you think most people would have agreed that through scientific studies one could prove the earth was flat?
No. Because that is not the way science is done. You try to show ideas to be
false. Not "prove" them. In science, "prove" is verbal shorthand for "I have shown to be false every alternative explanation we can think of."
At the time people thought the earth was flat they did not have a concept of "science" as we have it now. The theory that the earth was flat was developed based on
induction or conclusions from observations. These were very limited observations: standing on a flat plain, having the horizon
look flat on the ocean, having the sun and moon appear to go overhead from one side of the earth to the other.
However, once formulated, the theory did lend itself to what science does: making deductions.
For instance, you would deduce that, if the earth really were flat, that ships disappearing over the horizon would disappear all at once; that the shadow of the earth on the moon would have a straight line, that shadows at two different places where it was noon at the same time would have the same angle, etc.
Those deductions got tested. The Babylonians were an inland people and not sailors, so they missed the fact that ships dissappear hull first, with the top of the mast disappearing last. But they were troubled by lunar eclipses where the earth's shadow was a curve.
Erasthones showed that the earth was not flat about 500 BC with the shadows experiment. After that, the only people who thought the earth was flat were those that were ignorant of the data or who insisted on a literal reading of the Bible. And there were many of the latter. Enough that in 500 AD a book called
Christian Topography was published that advocated a flat earth based solely on the Bible. They didn't want to accept Erasthone's experiment and the other data.
That attitude sound familiar? Read your earlier posts.
