Discounting mountains, valleys, and other gross surface features, is there any place on Earth from which the Moon is not visible at all?
Asked by:

Answer
Just as the Sun is visible for 6 months out of every 12 at any point on the surface of the
Earth, the moon can be seen from any point on Earth's surface at some time. The Moon is
only 'invisible' to Earth in its 'New' phase when its lighted side faces away from
us.

'In a way science is a key to the gates of heaven, and the same key opens the gates of hell, and we do not have any instructions as to which is which gate.
Shall we throw away the key and never have a way to enter the gates of heaven? Or shall we struggle with the problem of which is the best way to use the key?'
