I just joined this forum and I can tell after just 2 to 3 days that most people here are just sick talking, unscientificly and absolutly not differentiated. All natural phenomena can be explained on round spinning and a flat earth. The experiments which are supposed to prove the earths rotation are a joke. The only way you can explain a spherical earth is to use gravitational force which is not understood yet. No one knows what it is. You only know what it does. I heard of experiments with something like a water filled telescope to analyse to light that falls in better to make calculations on the relative movement of the earth compaired to the stars. Maybe someone here knows about it. All evidence you can bring up from the earth face can never entirely prove its shape. So basicly as long as there is no space institute that provides the world with some better moving picture footage of a spinning globe in its full pride like NASA did, no one can tell. That little Clip on the NASA from 30 years ago is a joke, like much else they put out. There is a idiom we use here,, who lies ones, you dont believe in".
No. They can't.
There are various phenomenon which make perfect sense and are completely explained on a spinning round Earth, which make no sense at all on a flat Earth, stationary.
For example, the Coriolis effect (and things like Foucault's pendulum), make complete sense on a round spinning Earth, with movement over large distances resulting in an apparent curve, or an apparent rotation of the pendulum.
You have the stars as well, with them appearing to rotate around celestial poles, with stars in the north rotating around a northern one and stars in the south rotating around a southern one, and these are 180 degrees apart, regardless of where you are.
You have the sun, rising due east and setting due west for everywhere on Earth on the equinox, and providing 12 hours of daylight. This requires the sun to be very far away, yet it also goes directly over head the equator. The only way for that to work is for the equator and the sun to be in the same plane on the equinox, with the surface of Earth being perpendicular to that plane. Then there is the issue of the southern summer, where the sun rises from the south east, while on the FE model it remains to the north.
You have things setting behind the horizon rather than just disappearing off into the distance.
Even at 90 degrees south, Polaris should still be significantly above the horizon on a flat Earth, yet it isn't.
And associated with that lack of falling, on a flat Earth with close objects, their brightness should change dramatically, but it doesn't, indicating they need to be much much further away, so their apparent angle wouldn't change on a flat Earth.
And we have distances, where the distance between any 2 lines of longitudes decrease as you get further away from the equator, once again indicating Earth is round.
So no, only by completely discarding reality can all natural phenomena be explained on a flat Earth.
We don't completely understand any force, as we don't know the origin of things like charge.
Gravity is as well known as electromagnetism and the like. We know it exists, we just don't know everything about it, but like you said, we do know what it does, and it indicates Earth should be round, and that is just to explain its origin. It doesn't matter if we know its origin or not, we have enough evidence to indicate it is round.
Yes, Earth's surface does indicate Earth's shape, quite conclusively, with things disappearing behind the horizon and distances matching a globe.
As for the experiment, it failed to take into consideration the effect of light entering a dense medium which moves. Air isn't a significant problem due to its low density and refractive index of effectively 1, but water is much denser with a significantly greater refractive index, which means you do need to consider its movement.
So that experiment failed.
The experiment that worked was comparing the apparent position of a star at different times of the year. Unlike parallax, this effects all starts (in approximately the same location) the same.
This showed that Earth was moving, and changed its motion, or the stars were somehow moving around in small circles for no reason at all.
Why do you need a video of moving Earth?
How about a time lapse series of photos of a moving Earth?
NASA has very little (if any) reason to provide a video of Earth spinning, but they did from the ISS, you just can't see a lot of it.
What is the point? People like you will just deny it and claim it is fake.
If you want to see Earth spin, use EPIC, a camera on DSCOVR located at the Earth sun L1, which can observe Earth rotating by comparing the pictures taken at different times.
