In the past, people believed that the Earth was flat until someone proved that it was wrong. Now people believe that this earth is flat, despite all the evidence that it is completely wrong... Over the past 50 years, there have been numerous photographs of Earth from satellites, proving that the earth is shaped like a BRIDGE. Yet people still do not believe, even some people try to fly in the air with homemade rockets to prove the opposite. This is a daunting trend, the Internet users lack knowledge may be. Easily fooled, kids will probably have a misconception about the planet they are living in. If the Earth is a plane, the two stakes will have the same or nearly identical shadows, as they will all have a vertical angle. with the ground. Because the two balls of the two different piles, inferred two piles towards the sun in two different angles, we can conclude that the Earth is spherical. Or you can pick up the phone, call the person on the other side of the Earth to see if they are day or night. Unlike you, this Earth can't be flat. There are many ways to prove that the Earth can't be flat, but sadly until now we still have to prove that the Earth is spherical.
