Here’s 200...
Thanks.
1/2 https://www.youtube.com/watch?v=Xg0FfxHPGXs They are amateurs and they've shown the curvature in their video.
3 You've never seen droplets of water on an apple The water isn't flat. Or a water barometer? Or water ball in a zero-g airplane?
4&5 Gravity is pulling towards the center of the mass of the Earth.
6 Ships and the horizon.
7 if the project is large enough or need to be very precise, yes you have to calculate the curvature of the Earth. It was factored in during the construction of the Golden Gate Bridge.
8 If you know you elevation along the route, it's not complicated to dig 26 feet below sea level.
9 That book doesn't even exist.
10/11/12 The line goes along the curvature of the Earth.
13 With the lamp at the summit of Desierto (2390 feet) you can see it in Ibiza at an elevation of 1046 feet, which is easily achievable considering the highest point in Ibiza is 1558.
14 Pretty much the same thing, 3 peaks are high enough Foel Cwmcerwyn, Cerrig Lladron, Foel Feddau.
15 Gravity, air density, and auto-pilot.
It was fun, albeit repetitive on certain points. From your point of view, what was convincing in that video?
I don’t have time to reply to your Gish Gallop; of course if you have a decent argument you could elaborate so that anyone knew what you were talking about rather than just asserting a bunch of sentence fragments as if they are actual arguments.
When I look at that list, which because it is in bad faith I will never even fully read, I immediately see lame, low-hanging fruit that has already been and still is easily shot out of the saddle. For example right at the top of the list; number 3: water droplets are curved due to surface tension. Water surfaces in a slim container like a beaker have a meniscus (concave surface) due to surface tension. This is basic science.
Bodies of water are always flat. That’s why it’s called water level.
If you actually want to address any of these arguments specifically and in an organized, reasonable fashion, instead of trying to set a hundred small fires that I don’t give enough of a shit to reply to, feel free to focus one good argument.
Then give me one good argument instead of a video with 200 shitty.
The physics of water isn’t to “find and maintain its level. For starters, that is a rather vague description: what determines the level that it comes to and how does it find it? In reality, water, and liquids in general are shaped by gravity and other forces to the shape which takes the lowest amount of energy. The levels in the barometer are different because the trapped air in the closed section is at a higher pressure than the atmosphere to which the air in the neck is exposed. While there would be less energy from gravity if both levels were the same, it would take more energy to push back against the higher pressure air and the total energy of the water would increase.
In fact, if you take water into a zero-g environment (whether by parabolic flight or going to space) and squirt it into the air, it will form a sphere. The water doesn’t flatten out and “find its level” because the shape that has the lowest energy due to the interactions of the water molecules is a sphere. This is also why rain falls in drops and dew forms in beads.
Since the gravity of Earth pulls everything towards its center, the gravitational potential energy is equal along the surface of (approximately) a sphere centered at the Earth’s center of mass, with a sphere of a small radius having a lower energy that one with a larger radius. So to have the lowest energy, water would try to reach the smallest possible radius, so assuming that gravity is equal all around the Earth the surface of the water would come to the same distance from the center of the Earth.
Since you and the guy in the video did not include any sources or experiments to show that the surface of water is actually flat, I cannot really say a whole lot more, except that the tilt would not affect the surface of the water, neither would the wobble, really, since it takes so long, and the speed of the Earth travelling through space also would not change it at all, so yeah… not really sure why he mentioned those.
