The angle (or altitude) to Polaris approximately corresponds to the latitude of the observer. This fact is observed on every location on Earth where Polaris is visible.
By tracing the path to Polaris from multiple locations on the flat Earth model, the lines will not point to a consistent position of Polaris. The reason is that the Earth is a sphere and the flat Earth model does not represent reality.

Muslims perform their prayers by facing the Qibla —or the direction to the Kaaba in Mecca, Saudi Arabia. The direction of the Qibla is traditionally determined from the direction to the Sun when the Sun is directly overhead the Kaaba. If during the time the Sun is visible, it will indicate the direction of the Qibla.
If the results of the observation are drawn on the so-called ‘flat-Earth map’, the Qibla will not consistently point to the Kaaba. Only the calculation using the spherical Earth model will give us consistent results that conform to centuries of observation, from various locations on Earth. The reason is that the Earth is a sphere.

Crossing the continent of Antarctica is a feat that has been achieved multiple times. And it is only possible if Earth is a sphere. If Earth were flat, the expeditions would have to travel impossibly far, all the way to the other side of Earth.
Flat-Earthers claim that no such expedition has been attempted before. They are wrong. Crossing Antarctica has been done numerous times by multiple independent parties and using different methods.

In the Northern hemisphere, the Sun appears to move to the right. In the Southern hemisphere, it appears to move to the left. During sunrise and sunset, the path of the Sun forms an angle that roughly corresponds to the latitude of the observer. This phenomenon occurs because observers on the different locations on Earth’s surface is not standing on the same plane.
The path of the Sun observed from many different locations on Earth’s surface is evidence of spherical Earth. This observation cannot possibly occur on a flat Earth.

The perpetrators of flat-Earth often take emergency landings as ‘proof’ of a flat Earth. They would point out that the diversion airports used for such emergency landings are somehow consistent with the flat-Earth map.
It is not a coincidence that all the cases of emergency landing they pointed out occurred far in the north. At the locations closer to the north pole, the distortion of the azimuthal-equidistant map (claimed by flat-Earthers as the ‘flat-Earth map’) diminishes. It would seemingly appear as if the ‘flat-Earth map’ can explain the choice of the diversion airports. In many other locations, though, the flat-Earth map would fail to explain it.

Flat-Earth is a concept initially intended for the potential victims in the northern hemisphere. At a glance, some of the claims are seemingly in line with reality in the northern hemisphere, but they would fall apart when verified and tested in the southern hemisphere.
90% of all humans live in the northern hemisphere. It made sense for the creators of the flat-Earth notion to invent their ‘facts’ with the northern population in mind.

At any given time, there is an equal area of the Earth that is experiencing daytime, and that is having a night time. The reason is that the sun is very far, and it would illuminate a hemisphere of the Earth, and leave the other dark.
If we plot which areas of the Earth that are getting sunlight on an azimuthal equidistant map centered on the north pole, the sun would appear to illuminate a somewhat elliptical area during the northern hemisphere summer, and a lopsided Bat-Signal shaped area during the winter. During the equinox, the sun would appear to illuminate a half-circle area.

If we look south in any location in the southern hemisphere, we are going to see the same set of stars. The stars are seen rotating around the south celestial pole, in the Octans constellation, nearby the star Sigma Octantis.
This phenomenon is unexplainable in the flat-Earth model. Looking at the so-called ‘flat-Earth map’, we should see the different set of stars on the different location in the southern hemisphere. The reason is that the so-called ‘flat-Earth map’ does not represent the real Earth.

When a sniper shoots a long-range target, if he is in the northern hemisphere, the bullet is deflected to the right. Conversely, if he is in the southern hemisphere, the bullet is deflected to the left.
The phenomenon occurs because the Earth is spherical and rotating.

Diurnal motion is the apparent daily motion of stars around the two celestial poles due to Earth’s rotation. The stars move in a peculiar way that can only be explained in the spherical Earth model.
All the differences of diurnal motion that occur in the different latitudes on can never be explained in a flat Earth.

The December solstice occurs between the 20th and 22nd in December, which is when the Sun reaches its most southerly excursion. Around this time, the northern hemisphere experiences winter, and conversely, the southern hemisphere experiences summer.
If we try to plot the areas that are having daytime and nighttime on the so-called ‘flat-Earth map,’ the Sun would appear to illuminate an impossible area, similar to Batman’s bat-signal. This fact tells us that the ‘flat-Earth map’ does not conform to reality.
Continue reading “The December Solstice, When the Sun Illuminates an Impossible Area in the Flat-Earth Model”
During the December solstice, on December 21, the Sun reaches its southernmost point. During this time, the northern parts of the Earth are experiencing the peak of winter, and conversely, the southern regions are experiencing the height of summer.
Most flat-Earth denominations picture the sun shining like a spotlight, and they can’t explain what is happening in the southern parts of the Earth during the December solstice.

Long before GPS, navigators used a device called ‘sextant’ to determine the angle of a celestial body. From that data, the latitude of their current location can be determined.
This can only happen if the Earth is spherical.

The majority of the flat Earth models place the Arctic Ocean in the middle of the flat Earth, and Antarctica at the edge of it. The Sun is pictured floating and moving in a circle above it. The Sun’s area of light is limited to a circular area below it, like a spotlight.
A problem: a simple observation of day and night cycles in a different area of the world cannot be explained in this flat Earth model.

A cyclone or hurricane rotates in a different direction depending on which hemisphere it occurs. A cyclone rotates counterclockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere.
The phenomenon happens because of the Coriolis effect, which in turn occurs because the Earth is spherical and rotating.

We can use the duration of a flight route to roughly determine the distance between two locations. Then, we can use this to determine which model better represents reality: the flat-Earth model or the spherical Earth model.
In the flat-Earth Model, the distances between two locations become more unreasonable as we go further south. To illustrate this fact, we can use the flight route of Sydney-Santiago to help us with the calculations. This flight route is one of the most southernly flight routes.

Flat-Earthers think there hasn’t been anyone who has circumnavigated the Earth by traversing both the north pole and south pole in the process. All we have are explorers who have circumnavigated the Earth to the east or west, parallel to the equator; explorers like James Cook or Ferdinand Magellan. They don’t really have the choice, because if polar circumnavigation is possible, then the flat-Earth assumption falls flat.
But, like a lot of assumption in the flat-Earth community, it is simply not true. There are in fact many people who have done a polar circumnavigation, and the information can be easily found on the Internet.

There are many non-stop long-haul flight routes between two locations in the southern hemisphere, all without crossing the northern hemisphere. These routes can only exist if Earth is a sphere.
Some flat-Earthers claim there is no non-stop long-haul flights between two locations in the southern hemisphere. Flights need to make a stop in a location in the northern hemisphere because the distance will be too far and such flight will traverse the northern hemisphere, or more accurately, the center of the Earth according to their model. They are wrong. There are many such flight routes.

In the northern hemisphere, if we look at the sky to the north, we can observe stars rotate counter-clockwise around a point. This axis of rotation is not visible from observers in the southern hemisphere.
On the other hand, in the southern hemisphere, if we look at the sky to the south, we can observe stars rotate in the opposite direction. Conversely, this axis of rotation is not visible from observers in the northern hemisphere.
This motion of the stars cannot possibly happen in a flat-Earth. The motion of the stars is a proof that the Earth is round and rotates around its axis.

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.
