Re: 3 Experiments You Can Do At Home that PROVE THE EARTH IS FLAT
THE ANCIENT GREEKS knew the Earth was spherical. We've known the Earth was spherical since about several hundred years before Jesus lived. Why?
1.) When the sun is behind the Earth and the moon in front of the Earth, Earth makes a curved shadow on the moon, no matter what side of the Earth the moon is facing. If the Earth were flat, then it would make no shadow on the moon when the moon was above the horizon, much less a noticeably curved one. In other words, the moon would not have phases. It would not appear to be different shapes at different times.
2.) You can see different stars from different places on Earth, even when these observations are made at the exact same time. If the Earth were flat, you would see the same stars no matter where you were on Earth.
3.) Ships appear to sink as they sail farther and farther away from the observer. Why? Is it because all ships do, in fact, sink the farther they sail? Of course not. This would be alarming. No, it's because the Earth is curved, so the farther an object is away from you, the farther down it appears to be, since the Earth curves downward away from you. This is what is meant by "horizon." At some point, even with superhuman vision (you can try this using a telescope, if you want) you reach a point where you can't see farther along the Earth, simply because light does not bend around the curvature of the Earth, so you can only see things that are linearly in front of your eyes and your range of vision. If the Earth were flat, ships would not appear to sink as they got farther and farther away from you. They would appear to get smaller, but they would not appear to sink. There would also be no point at which it is impossible to see further along the Earth. The experiment here would be to use a high-powered telescope to observe an expanse where there are no mountains or anything blocking your field of vision. If you did this, you'd be able to see a point past which nothing can be seen, even though things at that point aren't simply so small that you can't see them. This can also be observed simply by studying photos of Earth taken from space. There comes a point when you can't see anything farther than the horizon, not because things become so small you can't detect them with your eyes, but because the Earth curves out of your field of vision.
