GozoGozo's True or False game deliberately includes several very widespread myths. Here are some of the most persistent ones, and why they're false.

1. "The Great Wall of China is visible from space with the naked eye"

This is probably the most repeated geographical myth in the world. In reality, the Wall is too narrow to be distinguished with the naked eye from Earth orbit, unlike wider infrastructure such as certain highways or urban areas. Several astronauts, including Chinese ones, have publicly confirmed this after their missions.

2. "Goldfish have a three-second memory"

This myth is so popular it's become a common expression to mock forgetfulness. Yet behavioral studies have shown that goldfish can retain information for several months, including recognizing shapes or rhythms associated with food.

3. "Bats are blind"

The saying "blind as a bat" is unfair. In reality, most species see perfectly well — they use echolocation in addition to their sight, especially useful in total darkness, but not because they're blind.

4. "Ostriches bury their heads in the sand"

This myth likely comes from confusion with a real behavior: ostriches do lower their heads to the ground to turn their eggs in the nest, which can create the illusion of burying it. Faced with real danger, their reaction is to run (they can reach 70 km/h) or lie flat on the ground to stay hidden.

5. "The Sahara is the largest desert in the world"

This one often surprises: a desert is defined by its lack of precipitation, not its heat. Under this scientific definition, Antarctica is actually the largest desert in the world — a desert of ice, but a desert nonetheless, far larger than the Sahara.

What makes these myths so persistent is that they've been repeated since childhood, often without ever being questioned. That's exactly the point of the True or False mode: to force a small pause before validating what you think you know.
