Sunrise and Sunset refers to the time of the day when the light of the Sun rises from or sets into the horizon. The Round Earth model describes sunset as a rotating spherical earth that obscures the Sun. The Flat Earth model describes sunset as the light of the Sun setting into the Flat Earth.
In accord with what we see, a rotating spherical Earth which obscures the Sun is not seen. We cannot see, feel, or detect it. We do not see the horizon rising upwards into the Sun, or have any direct experience for that position. The most direct description of what we observe is that the light of the Sun is setting into a Flat Earth.
Thus established that the most direct and natural interpretation is that the light of the Sun is moving and setting, mechanisms which describe how and why this occurs may be found below.
- Electromagnetic Acceleration describes the rising and setting of the Sun, as well as several other phenomena
- The Setting of the Sun as a Perspective Effect describes the traditional interpretation of sunsets as originally described by Samuel Rowbotham
- Magnification of the Sun at Sunset describes why the Sun does not shrink as it recedes
- The Equinox page describes why the Sun rises and sets from a generally Eastward and Westward direction
