Good questions
Cosmology
On some days, the sun and moon are visible at the same time, so does this mean the other side of the globe has no moon that night?
Why do we still have an atmosphere while our atmosphere (high pressure) has been leaking into space (zero pressure) for millions of years?
How does this interaction between atmosphere and space not cause a permanent wind on the earth which direction is opposite to the direction of rotation? Put differently, if there was no sun or moon, why would you not be able to determine the direction of rotation of the earth?
