Did someone travel around the world and end up in the same spot?

Did you really just ask this question?

no there's a lot of reasons but the one i like the most is that scientists discovered that when the Earth cast it's shadow onto the moon, the shadow was round
-
The Earth's shadow falls on the Moon occasionally and its always a segment of a circle. The only shape that casts a shadow like that is a sphere.
-
The earth isn't round. The earth is flat. Now excuse me while i go argue with Galileo about the sun and stars revolving around the earth.
-
Well yeah probably happen too ahaha but math proved it, physics proves it.
-
Satellites, airplanes, space shuttles, science and technology tells us this.
-
Because all fluids make a perfect sphere when in a vaccume and the when they cool,dry etc the have kept there shape.
-
They realized if you keep going, you can't fall off. And we can see it from space. Just saying.
-
Yes. I did.
-
Because I made it out of playdo
