Stars in the Southern Sky: Evidence That the Earth is a Rotating Sphere

Featured Video Play Icon

If we look south in any location in the southern hemisphere, we will see the same set of stars. The stars are seen rotating around the south celestial pole, in the Octans constellation, near the star Sigma Octantis.

This phenomenon can never be explained in the flat-Earth model. Looking at the so-called ‘flat-Earth map’, we should see another set of stars on a different location in the southern hemisphere. The reason is that the flat-Earth model is a false representation of the Earth.

Antipodal Flight: Shanghai–Buenos Aires

Shanghai, China and Buenos Aires, Argentina are a near antipodal pair. Both are located at the diametrically opposite points to each other on Earth’s surface. Therefore, we can fly from Buenos Aires in any direction and arrive in Shanghai after traveling a roughly similar distance, regardless of the course taken.

Any flight between an antipodal pair has a similar duration even though the different flights have different directions. This fact is only consistent with spherical Earth and cannot possibly be explained if Earth is flat.

Perth–Johannesburg Flight Route

Some flat-Earthers noticed some flights from Perth to Johannesburg have a flight change in Dubai. They use the fact to ‘prove’ a flat Earth. In reality, there are non-stop flights of the same route that are impossible to explain if the Earth is flat.

With a flight change in Dubai, the flight takes more than twice as long, as Dubai is nowhere near the non-stop flight path. In fact, Perth–Dubai is a longer hop than the direct Johannesburg–Perth route. These are consistent only with a spherical Earth and can never be explained if the Earth is flat.

Polaris Altitude from Multiple Locations on Earth

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.

The Direction of the Qibla Proves Earth is a Sphere

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

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.

Sun Path

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 Failure of Flat-Earth Model to Explain Emergency Landings That Occur More to the South

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.

The Southern Hemisphere: Where Many Flat-Earth Claims Fall Apart

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.

Day and Night Areas on a Flat Earth

Featured Video Play Icon

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.

The December Solstice, When the Sun Illuminates an Impossible Area in the Flat-Earth Model

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.

The Cities of Punta Arenas, Dunedin, and Murmansk During the December Solstice

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.

The Length of Daytime and Nights in the Flat Earth Model

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.

The Sydney-Santiago Flight Route: An Impossible Route on the Flat-Earth Model

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.

Polar Circumnavigation

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.

Non-Stop Long-Haul Flight Routes in the Southern Hemisphere

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.
