Mercury and Venus are closer to the Sun compared to the Earth. The best condition to observe these planets is during some time after sunset or before sunrise. In some cases, they are even visible in the day.
Many flat-Earthers think that it should be impossible to observe Mercury & Venus as they are closer to the Sun. They are wrong.

Turning Torso is a 190 m (623 ft) high building in Malmö, Sweden. It is situated near the strait of Øresund. At the other side of the strait lies the city of Copenhagen, Denmark, only 15 km (9 miles) away from Malmö. Turning Torso has a distinctive segmented shape that is easy to recognize from far. And more importantly for our purposes, the segmented form is making it easy to judge its height from far.

The Apollo missions were real and humans have actually visited the Moon. If someone fell victim to the flat-Earth conspiracy, then it would imply that they also fell victim to the Apollo moon landing conspiracy. They are wrong.
Someone usually fell for the moon landing conspiracy theory because of provocation and confirmation bias, and also because of their ignorance of the Apollo mission profile itself.
The following is a very brief description of the Apollo mission profile, numbered according to the numbers in the illustration.

Cognitive dissonance is the mental discomfort experienced by a person who simultaneously holds two or more contradictory beliefs.
Cognitive dissonance often happens with devoted flat-Earthers when they are confronted with facts and evidence showing that the Earth is spherical. Continue reading “Cognitive Dissonance”
The Earth is a sphere, a three-dimensional shape. But most of the time, we work with two-dimensional media, including paper, computer displays, televisions, phone screens, whiteboards, etc. To represent the Earth on a two-dimensional medium, it is necessary to transform the curved shape of the Earth’s surface into a planar form using one of the many map projections.
All map projections necessarily introduce distortion into the results. Some flat-Earthers think that distortions are ‘evidence’ of failure of modern science to explain the world. They are wrong.

The directions of up and down are determined from the direction of the Earth’s gravitational acceleration. Up is in the opposite direction, and down is in the same direction as the Earth’s gravitational acceleration.
Flat-Earthers are often seen making fun of this fact. They show us ‘upside down’ pictures taken in the southern hemisphere. They are wrong. To anyone in the southern hemisphere, down is in the same direction as the Earth ‘s gravitational acceleration, the same as anyone in the northern hemisphere.

In a talk show, Neil deGrasse Tyson explained the figure of the Earth. He told the audience that the Earth is practically round, but it is a little farther from the center near the equator compared to the poles. And that in the southern parts, it is a bit farther from the center than in its northern regions. To illustrate the fact, Neil used the analogy ‘pear-shaped.’
Flat-Earthers really love to ridicule the ‘pear-shaped’ analogy. But they are mistaken. If they watch the entire unaltered video, they will find Neil explained the fact very clearly.

If Earth’s gravity pulls everything towards the Earth, then how can satellites stay up there and are not falling towards the Earth?
The answer is that satellites orbit the Earth. They have the correct velocity with respect to Earth’s position and gravitational pull.

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 parts are experiencing the peak 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.

We can’t directly observe and subjectively perceive the curvature of the Earth from a position close to the surface. And this matches the expectations in the spherical Earth model.
Flat-Earthers often take the fact we can see the curvature by standing on a beach as ‘evidence’ the curvature doesn’t exist. They are, once again, wrong.
