A rippled by a locally smooth surface such as water with waves will. By placing it over a curved surface, we can see it producing the same result. Sun glitter is a bright, sparkling light formed when sunlight reflects from water waves. The reflection of rippling water can be easily simulated using a sheet of wrinkled aluminum foil. Pictures of Earth taken from the Himawari-8 satellite, for example, look similar to the characteristic of the reflection on their simulation. Their simulation was more suitable to describe how sunglint -the reflection of the Sun on the smooth ocean surface- appears from space. Their mistake was placing the observer too far from the surface, making far too large of a curvature to represent spherical Earth, and using an even, smooth surface. It can easily occur on a curved surface and does not prove a specific shape of Earth.įlat-Earthers like to devise a “simulation” to show that a curved surface does not form the shape of reflection similar to what we observe during sunset and incorrectly concluded Earth is not a sphere. In reality, the shape of the reflection is the result of the rippling water surface. As a result, a viewer in the right position will see many small images of the sun, formed by portions of waves oriented correctly to reflect the sun’s light to the viewer.įlat-Earthers use the long shape of the sun’s reflection on a water surface to “prove” Earth is flat. A rippled by a locally smooth surface such as water with waves will reflect the sun at different angles at each point on the surface of the waves. Sun glitter is a bright, sparkling light formed when sunlight reflects from water waves.
