If you’re curious about how the entire equation is developed, you can check it out on this site here. This calculation uses a fairly precise measurement for the earth’s radius and will give you very accurate numbers. That means 1.22459 (a number we derive from knowing the radius of the earth and using the Pythagorean Theorem) times the square root (√) of your eye height (h). #Flat earther perfect horizon full#The full method of achieving this formula is needlessly complicated but know that, when using the proper radius of the Earth, you can get a simple formula for determining distance to horizon. For our calculation we’re going to use 3,958.8 miles. ![]() The one piece of information you need going into this is the radius of the Earth itself. The calculation will therefore be different for a person standing on the deck of a fishing trawler compared to someone sitting in a kayak. Not all of us stand the same, right? And you’ll be using the height of your eyes as a guide, since that’s the point you’re measuring from. Well, the first thing you need to know is where you’re standing. ![]() So, how do we determine the distance from where we’re standing to the horizon? If you have an app on your phone or even an old almanac it may not be so hard. It’s a little mind bending when you think about it. The water you’re looking at is actually curving into the distance with the shape of the Earth. And though it looks like a flat run from you to the edge of the planet, you know that’s not true. You’re looking out from your boat across the water to the horizon line. Consider what you’re trying to figure out, after all. Not necessarily complicated, but not intuitive either. Flat Earth Debunked.Calculating the distance to the horizon takes a bit of clever math. Flat Earth Water Level Test #2 – Jon McIntyre – YouTube.Flat Earth Water Level Test – Jon McIntyre – YouTube.It is not that much different from 0°, or ‘horizon is at the eye-level’. If the distance to the ‘edge of the world’ is 5000 km, then the dip of the horizon from the altitude of 2 km is 0.023°. So, we created this diagram to illustrate what would happen in the flat model. ![]() But some of them -presumably after reading this piece- claims that the dip of the horizon also happens in the flat-Earth model. “The horizon always rises to eye-level” is claimed by most flat-Earthers. The surface of the water is level, or equipotential, but not perfectly flat. Conversely, as we approach sea level, the dip approaches zero.įlat-Earthers often use water level as ‘proof’ that the surface of the water is flat. If we are at a sufficient altitude, we should be able to observe that the horizon -the line separating the sky and the ground- lies below the eye-level.Īs we climb higher, the larger is the dip. Looking at the surface of water formed in two vessels, we can aim at the horizon and determine the projected eye-level. Despite their insistence to use a water level to ‘prove’ water is flat, the same device can be used to demonstrate the dip of the horizon, proving the water surface has curvature, and consistent with the spherical Earth model.Ī water level exploits the fact that water always finds its level. The angle becomes larger as we go higher.įlat-Earthers often claim that “the horizon always rises to eye-level”, and thus ‘proving’ the flat Earth claim. The angle between the eye-level and the horizon is the dip of the horizon. As the Earth is spherical, the horizon is below the eye-level (or the astronomical horizon). ![]()
