We really shouldn’t need more proof that the Earth is round, but here we are.

Recently, an astronaut posted a video from space that practically puts an end to the ‘flat Earth’ theory once and for all.

The idea that the Earth is round is far from new. We've known about it for thousands of years. Despite the misleading 2D maps and tales about Christopher Columbus, the concept of a spherical Earth has been around since the time of the ancient Greeks.

In fact, Greek philosopher Pythagoras proposed the idea long before his death in 495 B.C.

However, the myth that the Earth is flat, like a tabletop, has persisted through the centuries.

While it’s true that misconceptions about the planet's shape were more prevalent a few hundred years ago, the idea of a flat Earth still lingers in certain circles, even in today's information-rich age.

Astronauts, who’ve witnessed the Earth’s round shape from space multiple times, must find the flat Earth theory particularly amusing.

Still not convinced? Take a look at this video from an astronaut that’s been circulating on social media. It clearly shows the Earth’s curvature. The video was shared on the TikTok account spacemanedu, a well-known source of space footage.

In the video, an astronaut waves at the camera before flipping it to reveal Earth in all its spherical glory.

The caption reads, "Someone said Earth was flat."

For those still unsure, NASA regularly shares photos and videos from space, showing Earth as seen from the International Space Station. You can find these on NASA’s social media accounts, including their Instagram dedicated to Earth.

So why do some people still insist the Earth is flat?

In the past, ancient civilizations might have believed the Earth was flat because they lacked the tools to prove otherwise. But with all the evidence today, why does the flat Earth theory still hold weight?

The roots of this modern belief can be traced back to the 19th century and inventor Samuel Rowbotham. He proposed his 'zetetic astronomy' theory, claiming that the Earth was a flat disc centered around the North Pole.

Other flat Earth advocates, such as William Carpenter, later echoed his ideas.

So how should you deal with someone who believes the Earth is flat?

Should you ignore them, or bombard them with a mountain of evidence? It's not always that straightforward. Paul M. Sutter, an astrophysicist at SUNY, wrote an article for Space.com where he suggested that the modern flat Earth belief reflects a deeper distrust in science and scientists.

He explained, “By claiming the Earth is flat, people are expressing a deep distrust of scientists and science itself.”

So if you find yourself in a conversation with a flat Earth believer, skip the facts and evidence. Instead, try focusing on how to build trust.
