Question

We cannot see the entire earth at the same time. Why?​

Answer 1

Because we don't live in space. Therefore,from space we can see the whole earth.

Answer 2

Explanation:

Therefore, you would need a bare minimum of three GPS satellites in order to "see" the entire globe at once. In reality, the earth is not a perfect sphere, mountains can get in the way, and the atmosphere itself bends light, so that four GPS satellites would be needed to "see" the whole earth at once.
