Earth is not flat

"Water being claimed to just "find it's level" is a vague and unscientific way of expressing the physics of liquids. Water actually conforms to the forces acting on it, this is an undeniable fact." If the water is at rest, as agreed upon, a body of water's surface will always be found flat. This is impossible if the earth is a ball. All bodies of water should have a measurable degree of curvature. "Just put water in any container and it will easily conform to the shape. " We're not talking about the bottom of water. We're talking about it's surface. I agree that water takes the shape of it's container, and that the surface will be flat, as pro stated in round 2. "if you pour it into a wine glass for example, it does not become flat until you stop pouring it and eventually the top becomes flat." -youngastronomer This is a non-sequitor. Saying that water conforms to its container and seeks a flat (level) surface does not equal "So it's easy for water to sit on a giant sphere with trillions of tonnes of mass" . This would require evidence that a body of water will conform to the the exterior of it's container, which has never been observed, and is unheard of. http://www.ericdubay.com... "what force causes water to simply find it's level I should ask my opponent? So for short, water does not simply "find it's level", it easily and naturally conforms to the forces acting on it." Air pressure? Barometric pressure? Either way it's level and this burden of yours is unmet and just gains a few tonnes. "My opponent says adhesive force is not gravity, no it's a simulation of gravity. Earth has enough gravity to hold the water on Earth, it also pulls to the center and not downwards, hence people in Australia don't feel upside down." Yes, it's also a simulation of gravity and glue, we're looking for evidence here. You have a burden here, and a simulation of gravity does not meet this burden. I'm well aware of what the theory states. "To see the whole ball shaped Earth, a satellite would have to travel about 900,000 miles as shown in the website showing pictures of Earth, all different due to the rotation. https://epic.gsfc.nasa.gov...... Before my opponent vaguely claims that they are CGI (which they are not), these are true photographs, notice I said they are photographs not computer graphics. I hope my opponent understands that those are photographs." I hope my opponent realizes that an unverifiable image on a computer proves nothing. NASA can claim it is a photograph all they want, they also claim that were on a spinning ball too. There isn't conclusive evidence for either statement. Since we have agreed that a body of water's surface will be flat, the evidence suggests that this is not an actual photograph. Along with one of the alleged satellite's flagship "photographs" many anomalies. http://thecoincidencetheorist.com... "It's a common claim that the horizon remains at eye level but it is only an assertion, how do you determine that the horizon rises to eye level? As you rise to a higher elevation, the horizon gets further and further away, with simple geometry (horizon dip angle), the viewing angle increases very slowly. 100 feet = 0.17 degrees 1000 feet = 0.56 degrees 10000 feet = 1.7 degrees 40000 feet = 3.5 degrees" Where is the math on this? How did you come up with these numbers? We cannot assume this as truth until it is mathematically shown. Then, what about 100,000+ feet?
