🧵 WHY THE EARTH ISN’T FLAT — AND WHAT TOILETS IN AUSTRALIA ACTUALLY PROVE
One of the most popular “gotcha” arguments flat-earth believers love to bring up is this:
“If the Earth is round and spinning, why does water flush differently in Australia than in the United States?”
Ironically… that argument does the exact opposite of what they think it does.
Let’s break it down — slowly, clearly, and without NASA CGI or government talking points.
Just physics.
⸻
🚽 The toilet myth (first, the truth)
Here’s the honest part most people don’t know:
👉 Toilets themselves do NOT prove anything
They’re engineered systems.
The shape of the bowl, jet direction, and plumbing design determine how water spins.
So no — your average Home Depot toilet isn’t a scientific instrument.
BUT…
When water is allowed to drain naturally, slowly, without external force — like in large bodies of water or carefully controlled experiments — the direction of rotation DOES change depending on hemisphere.
And that’s where things get uncomfortable for flat-earth theory.
⸻
🌪️ Enter the Coriolis Effect (real science, not theory)
The Earth rotates once every 24 hours.
That rotation causes moving fluids — air and water — to curve over long distances.
• In the Northern Hemisphere, large systems rotate counterclockwise
• In the Southern Hemisphere, they rotate clockwise
This is why:
• Hurricanes spin opposite directions
• Ocean currents curve differently
• Atmospheric circulation flips below the equator
If Earth were flat and stationary, this wouldn’t happen.
There would be no hemispheres.
There would be no consistent directional reversal.
There would be no mathematical model that works worldwide.
But there is — and it does.
⸻
🌍 Why Australia matters
Australia is in the Southern Hemisphere.
That means:
• The planet is rotating under moving water in the opposite orientation compared to the U.S.
• Gravity pulls water toward Earth’s center
• Rotation subtly influences how that water moves over distance and time
This isn’t opinion.
This is why navigation, aviation, satellites, and weather prediction actually work.
Flat-earth models cannot explain this without inventing new forces that magically stop working at the equator.
⸻
📐 Flat Earth’s biggest problem isn’t toilets — it’s consistency
Here’s the real issue flat-earth theory can’t escape:
👉 It has no working global model.
No flat map:
• Explains time zones accurately
• Explains satellite triangulation
• Explains GPS drift correction
• Explains southern star rotation
• Explains Coriolis-based artillery adjustments
• Explains why flights don’t take the routes flat maps predict
A theory that only works in YouTube comments isn’t a theory — it’s a vibe.
⸻
🧠 Why the myth survives
Flat-earth ideas persist because:
• People distrust institutions (understandable)
• NASA becomes an easy villain
• “Hidden truth” feels empowering
• Simple explanations feel comforting
But skepticism without rigor becomes fantasy.
Question authority — yes.
Ignore physics — no.
⸻
🧪 Real experiments anyone can verify
You don’t need NASA.
You can verify Earth’s curvature by:
• Watching ships disappear hull-first
• Observing different constellations by latitude
• Measuring shadow angles at different locations (Eratosthenes did this 2,000 years ago)
• Tracking flight times and routes
• Observing weather systems across hemispheres
Reality is stubborn.
⸻
🌐 Final thought
The Earth isn’t round because the government said so.
It’s round because:
• Math works
• Physics works
• Navigation works
• Engineering works
• And reality keeps lining up no matter who’s in charge
Toilets don’t prove the Earth is flat.
They accidentally point to something much bigger:
👉 We live on a rotating sphere, and the universe doesn’t care about internet theories.
