Why Moonlight appears tilted
For the sake of simplicity, let us assume that the Moon is in 'half moon phase'. It is during the day, about 12 p.m. You go outside and notice that the Sun and the Moon are in the sky at the same time today. The Sun is directly above you. You look to your left and you notice the Moon in the sky. You see that the light on the Moon is tilted. This is because of the 'Law of Perspective' as shown above.
Many people have come to the conclusion that the Moon 'magically' generates it's own light because it's light reflected is not perpendicular to the Sun. This is simply not the case. What has really happened is that the 'Law of Perspective' simply has changed our view of the Moon, and made it's lit part appear tilted.
You see? Many people think that the law of perspective only exists on ground level, but it exists above us in the sky also.
In our second example, it is 12 noon again, and this time you walk outside and notice that the moon is far over to the right. Here's what it would look like:
In our third example, it is 5 p.m, and this time you walk outside and notice that the moon is directly in front of you.
Because it is directly in front, it's sunlight reflection is straight up and down. (Verticle)
Notice that there are 12 spaces in the 'arch'. These spaces represent the 12 hours of daylight.
The line in the middle represents where the 11'th hour meets the 12'th hour, or '12 noon'.
Although it is not presently '12 noon' in the diagram above, you can calculate what time it is by counting how many spaces from the Moon to the Sun, which in this example is '5 spaces', which calculates to '5 p.m.'
This is because the Moon, in this diagram, is located in the '12 noon spot'.
(The spot where 12 noon happens in your area.)
And also, the Sun is the 'master time keeper', which always marks out where '12 noon' presently is.
So, in this diagram, 12 noon on the Earth is presently 5 hours ahead of where this 'Silhouette man' is standing.
In our fourth example, it is 3 A.M , and this time you walk outside and notice that the moonlight is upside down. It may seem absurd, but this is very common.
And although the chart I made is '2 dimensional', it still can be used, although in a manner you may have to get accustomed to*. (Read below)
** The 'Law of perspective' causes the view in front of us to diminish....
The diagram above looks misleading, but is the only way I can draw it.
