The topic of tide come up frequently in the flat-Earth community. Let’s examine some of the ‘issues’ they brought up about tides in Q&A format.
Some flat-Earthers consider crepuscular rays as evidence that the Sun is not far. In their mind, the Sun is only about ±5000 km circling above us. In reality, the actual distance of the Sun is ±150 million km.
Practically every illustration showing the Sun, Earth, and Moon is drawn not to scale. The reason is that the sizes of celestial bodies are far too small compared to the distances between them.
Flat-Earthers sometimes use this fact to point out the alleged “failure of modern science” to describe celestial bodies, or even “a mean to deceive us all.” However, the real reason is just that it is practically impossible to create a model of the solar system in the actual scale, using static images, that still effectively describes the objects it is trying to explain.
Midnight Sun is a phenomenon where the Sun remains visible at midnight. This phenomenon occurs in the summer months north of Arctic Circle, and south of the Antarctic Circle.
The apparent motion of the Sun in both polar regions is different. In the north polar region, the Sun moves from left to right. On the other hand, in Antarctica, the Sun moves from right to left. There is no explanation other than that Earth is a sphere.
We know for granted that during an equinox, the Sun rises from the east and sets in the west. Such facts are undisputed and have been verified through centuries of observation.
The flat-Earth model, however, is unable to accommodate this simple fact. And thus, it is not hard to conclude that the flat-Earth model does not represent reality.
Having the total height of about 830m, Burj Khalifa is the tallest building in the world. It is so tall that we can observe the sunset at the base of the building, then rush to the upper floors and watch the same sunset again for the second time on the same day.
This phenomenon can only happen if the Earth is a sphere. On a higher position, we will observe the sunset later than when we are closer to the ground.
