Disproving the Flat Earth Theory

What is the Flat Earth Theory?

• Belief that the Earth is a disk
• 150 foot tall wall is on the outer rim
• All missions to space are fake

Reasons why the Earth is round

• The moon
• Ships and the Horizon
• The change is constellations
• Shadows and Sticks
• Seeing farther from higher
• Ride a plane
• The existence of timezones
• The Center of Gravity
• Images from space

The Moon

• Lunar Eclipse: the Earth is directly between the sun and the moon
• Shadow is round

Ships and Horizon

• Ships look like they are coming from under water
• Materialize

Constellations

• Further away from equator the stars you know change
• Aristotle first noticed this when he took a trip to Egypt

Shadows and Sticks

• Principle for Shadow Clocks
• Shadows move as time passes
• Used to discover the circumference of the Earth

Seeing Farther from higher

• If the Earth was flat you wouldn't see farther from higher
• Usually related to Earthly objects being in the way

The existence of timezones

• If Earth was flat we would see the sun all the time
• One side of the planet is day while the other is not
• The only way this could happen is if the world is round

Center of Gravity

• Gravity will always pull towards the center of objects
• No matter where you stand on sphere you have the same amount under you
• On flat plane gravity is in the center
