-
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.

-
