You have to laugh when someone states that light bends up and then draws a diagram of light bending down and then up LOL.. Self contradiction to mold and ideological construct around unintelligent manipulation of information. Especially when I can actually prove this theory of his incorrect via use of mirrors, or simply by calling Japan and asking them where the damn sun is in the sky.. According to Flat Earther's the Sun would set at the same time across the globe, and it shouldn't be dark outside in Japan while it's a bight sunny day in Minnesota. Do you people really fail at critical thinking skills so badly that you actually follow nonsensical religious like garbage like FET?.. And sorry, photons don't all bend and travel all in the same directions, anyone with a mirror can see why this is. It's like the people here have no concept of light refraction. Yes we can bend light with the application of enough gravitational force, or by reflection.. However, you know someone has lost this argument when they start making nonsensical garbage up like "salt can effect the lens" in a dishonest effort to deflect from the argument. This site sounds more like a creationist website than anything else..
