I'm not 100% sure of this, but I think this subject is not off-context. Then it should "fit" in Flat Earth General.Ok, you all know that it is uncomfortable to express your opinions about earth's shape in our current society, where round earth is considered an absolute and unquestionable truth. I have did it in school, and that didn't went so well. I'm in the first year of the High School, and here we are taught obviously that the world is round, this is a recurrent theme in Geography and Physics. But I will speak specifically about my discussions with my Physics teacher on earth's shape. You know, we have to frequently "swallow" the idea that the earth is round and orbits the sun, as well that the sun is a star, space travel is possible, NASA doesn't lie etc. Some weeks ago, I was listening to these things told by my teacher and then I raised my hand and said: "Teacher, I know a group, a kind of organization, which believes that the earth is flat, and NASA fakes its images.". He answered: "Really? They're ignorant. It was proved that the earth is round. I can think about the possibility of geocentric models, maybe. But a flat earth is impossible."
If you are an FET believer, reply with your best arguments and I will attempt to refute them. If I cannot refute them, I will be forced to accept FET.
Well it certainly contradicts most FErs model of the solar system."The first successful measurement of c was made by Olaus Roemer in 1676. He noticed that, depending on the Earth–Sun–Jupiter geometry, there could be a difference of up to 1000 seconds between the predicted times of the eclipses of Jupiter's moons, and the actual times that these eclipses were observed. He correctly surmised that this is due to the varying length of time it takes for light to travel from Jupiter to Earth as the distance between these two planets varies. He obtained a value of c equivalent to 214,000 km/s, which was very approximate because planetary distances were not accurately known at that time."
