Ancient civilizations such as the Greeks, Egyptians, and Chinese initially believed the Earth was flat. The Greeks were among the first to propose a spherical Earth, with Pythagoras and later Aristotle providing observational evidence. Despite overwhelming scientific proof, flat Earth theories persist even today. A 2018 YouGov poll found that 2% of Americans firmly believe the Earth is flat, with another 5% expressing doubts about its roundness.
But why do these ideas persist in the 21st century? Psychological studies suggest that flat Earth beliefs stem from distrust in authorities, confirmation bias, and the appeal of contrarian viewpoints. Social media platforms like YouTube and TikTok have played a significant role in spreading these ideas, with algorithms often promoting conspiracy-related content.
Jeran Campanella, a vocal advocate of the flat Earth theory, spent $37,000 (₹31.4 lakhs) traveling from California to Antarctica in an attempt to prove his point. Campanella believed Antarctica was an "ice wall" that circled the edge of the Earth and that the Sun's behavior there contradicted mainstream scientific understanding.
Surprisingly, even celebrities like Kyrie Irving and B.o.B have expressed support for flat Earth theories, fueling further public interest. Irving later apologized, admitting he had been drawn into conspiracy videos online.
However, Campanella's journey yielded unexpected results. While in Antarctica, he witnessed the 'Midnight Sun' – a phenomenon in which the Sun remains visible for 24 hours, an occurrence only possible on a spherical Earth. This experience forced him to reconsider his stance, though many in the flat Earth community dismissed his findings as fabricated or manipulated by external forces.
The flat Earth theory relies heavily on misconceptions and misinterpretations of simple physics and perspective. Flat Earthers argue that NASA's images are digitally altered and that the curvature of the Earth is not visible to the naked eye. However, scientific demonstrations dating back to Eratosthenes' shadow experiment in 240 BCE have consistently proven Earth's curvature.
Scientific evidence supporting a round Earth is abundant:
- As ships sail over the horizon, their hulls disappear first, while the mast remains visible.
- During lunar eclipses, the Earth casts a round shadow on the Moon.
- Time zones exist because the Earth is a sphere, rotating and exposing different parts to sunlight.
- The Coriolis effect causes weather patterns to rotate differently in the northern and southern hemispheres.
- GPS satellites orbit the Earth, relying on its curvature to function accurately.
Despite these facts, flat Earth conventions continue to attract hundreds of attendees annually, highlighting the persistent appeal of alternative theories. The Flat Earth International Conference, for example, draws enthusiasts from around the world, sharing ideas and "evidence" to challenge mainstream science.
Ultimately, the flat Earth theory serves as a reminder of the importance of scientific literacy and critical thinking. While it may seem amusing or harmless, the rise of such beliefs reflects broader issues related to misinformation and the erosion of trust in scientific institutions.
What’s your take on the flat Earth debate? Can you think of more ways to prove Earth is round or flat?
