In a world where the shape of our planet has been long settled, there are still those who cling to flat Earth theory. This is why you will come across those who want nothing but to continuously debunk flat Earth, even if only jokingly.
The Selfie That Settled Flat Earth Theory
An adventurous soul decided to take matters to new heights, quite literally. Scaling Mount Everest, the world’s highest peak, was the chosen battleground to debunk the Flat Earth notion. And what weapon did this modern-day explorer use? A selfie.1
After reaching the peak, the triumphant climber snapped a photo and posted it on Reddit, cheekily captioning it, “Checkmate flat Earth society.” The response was a mix of humor and validation for the spherical Earth theory. Those of the flat Earth theory can claim the photo was taken with a fish-eye lens, sure. But here are a few more reasons why the Earth is round:
The Case for a Spherical Earth
Lunar Eclipses: Aristotle’s Observation
Aristotle’s keen eye noticed the round shadow cast on the moon during lunar eclipses. This consistent oval shadow across various eclipses solidified the idea that the Earth wasn’t only round but spherical—beyond doubt, not flat.2
Ship Horizon Effect: The Vessels at Sea
One might observe ships seemingly emerging from the sea on the horizon, but this isn’t a magic trick. It’s the curvature of the Earth at work. The gradual emergence of ships aligns with the planet’s curvature, not a flat surface.
Star Observations: Changing Constellations
Astronomical observations by Aristotle after returning from Egypt revealed that certain stars were visible in Egypt and Cyprus but not in northerly regions. This change in visible constellations based on location suggested a spherical Earth. Flat Earth theory currently cannot explain this.
Shadows and Sticks: The Wandering Shadows
By observing shadows produced by sticks in different locations, Eratosthenes concluded that the Earth couldn’t be flat. The variance in shadows reaffirmed a curved Earth, not a level plane.
Height Perspective: The Higher You Go, the Farther You See
Ascending to greater heights offers an extended view. This phenomenon doesn’t occur due to obstructions on the ground but is a direct result of the Earth’s curvature, reinforcing the spherical shape. If flat Earth theory were true, you would be able to see a far greater view (if there were no obstructions) without needing to climb somewhere high.
Airplane Observations: Circumnavigating without Falling
Traveling long distances by air, planes remain aloft without ever tumbling off the Earth’s edge. Their ability to circle the globe without incident aligns with a spherical planet.
Observations of Other Planets: Celestial Consistency
The characteristics of other planets, including their spherical shape, align with what we observe on Earth. If diverse celestial bodies share this trait, it’s logical to presume our planet does too.
Time Zones: A World of Differences
Time zones with distinct differences in daylight confirm a round Earth. The existence of time variations points to a globe where sunlight and darkness differ across regions simultaneously.
Gravity: Pulling Toward the Center
Gravity, attracting objects toward the center of mass, is consistent with a spherical Earth. Objects fall directly downward, not sideways, further confirming our planet’s shape.
Space Images: A Consistent Spherical Image
Decades of space exploration have provided consistent images of the Earth as round. From satellites to the International Space Station, these visual records reinforce the spherical nature of our planet.
Why the Flat Earth Theory Doesn’t Hold Up
The Earth isn’t flat—multiple, centuries-spanning proofs affirm its roundness. These varied observations and experiments, spanning cultures and scientific methodologies, offer a robust case for our planet’s spherical nature. While the selfie from Everest might offer some comic relief, it’s these steadfast, time-tested observations that truly confirm our planet’s spherical nature.
So, next time someone argues for flat Earth theory, remember the countless observations, experiments, and space images that tell a very different story. The Earth? Round as ever.
