I'm an amateur astronomer. It turns out that there are a lot of things that you can see with a decent telescope. I have a few questions for the flat-earthers here on this forum.
One of these things is the ISS. When it was brought down in 2001, you could also see the MIR space station catching fire. There are also plenty of meteorites falling out of the sky that are visible with the naked eye. If the Earth is under a "celestial dome," then where do these things come from? How are the (visible) space stations remaining in orbit?
We can use parallax to determine how far away celestial bodies are. The way this works is we compare the angular location of a particular body at one point in time to its angular location at a different point in time. The difference in angular location may be used to determine the distance of that body. This works well for close bodies (less than a few tens of light years). If the scientific model is wrong, then God must have really taken his time in fabricating a model of the heavens.
The FE contention is that there are huge radio towers broadcasting signals, and that there are no satellites. By my estimation, in order to provide a range of coverage similar to a satellite in low Earth orbit (124-1240 miles) on a flat surface, one would need a radio tower fifty miles tall. Where are these radio towers? Does anyone have any pictures?
If the world is flat, then there is no horizon (or if there is, it's further away than eleven miles). With a powerful enough telescope, it should be possible to see across any adequately flat surface of the Earth--such as a large body of water, or an ocean. In fact, it should be possible to see the lights of Chicago from Michigan. Has anybody tried this?
Assume the sun is, in fact, 33 miles in diameter. The average power flux at Earth's surface is approximately 340 W/m^2. Multiply this power by the Earth's surface area of 486954715 miles^2 (according to your estimations of diameter, and assuming a flat Earth) and one has, as a result, a total power interception of about 428 PW (10^15 W). This solar spotlight would therefore have to emit power at a flux of 428 PW / ((33 mi/2)^2 Pi) at an intensity of about 193 MW / m^2. According to the E=mc^2 relation, this spotlight would have to annihilate a total of 1.2 kilotonnes of matter per year, the equivalent of a Heroshima nuclear detonation every five minutes. Can you provide a scientific explanation for this phenomenon?
If the reason shadows on the surface of the moon are visible is because of reflected light from the Earth, then why is the moon still visible at night? If it's visible during the night because of light reflected from the daytime side, then why is it invisible during a solar eclipse?
According to the scientific model, the Earth's shadow is responsible for the various phases of the moon. If this is not the case, then how can one account for the existence of profile shadows of terrestrial mountain ranges on the moon's surface?
Can you provide a specific reason, something that can cause all of the countries of the world to unify covertly in spite of war, for fabricating the existence of a round Earth?
