As we can see, the light from behind the glass is bent downwards as it passes through the thick medium of the water. While this is an extreme example, it shows that light is malleable, able to bend and conform based on existing conditions. When the light of the sun moves from the vacuum of space into the atmosphere of the earth all light rays except for rays which are vertical are gradually compelled downwards into the surface of the earth. The refractive index of air is a bit less than water, and so the effect will me more gradual, taking place over tens of thousands of miles instead of abruptly like the above image.
Pointing out my clone's contradictions is like doing the same thing to the bible, it's too damn easy.
There is no contradiction. Flat Earth Theory holds that the sun is a sphere which emits light in all directions. Due to Snell's Law the light of the sun is constrained to a large spotlight upon the earth.
Are you aware that refraction in air is hugely different from refraction in water? If you're not, then I suggest you read about breakings indeces. Furthermore, light hardly changes angle when entering Earth's atmosphere. You can calculate it if you want.
Here I'll do it for you:
The breakings index (n) of going from a vacuum to air is 1.00029. (that of water is about 1.330 - 1.341)
sin i/sin r = n
With i being the angle of the incident ray, and r being the angle of the refracted ray.
Say a ray of light enters at an angle of 20 degrees. Let's insert the number:
sin 20/sin r = 1.00029
sin r = 1,00029 * sin 20
sin r = 0.3421193292...
r = 20.00604776...
That's a 0.00604776 degrees of refraction... Hardly diverts a ray of light over 3000 miles by a whole centimeter.
