No flat earther (at least not me) is dismissing your work. It is very interesting and I credit you for it.
The problem is that it does not prove or disprove the flat earth.
.
What I am proposing here is nothing new. There are plenty of observers for many centuries now who have been doing these things, and their observations are instructive, that is, if one bothers to pay attention.
.
The scientific method properly followed allows the observer to confirm or deny a hypothesis based on empirical evidence. It cannot define whether something will always be the case in the future -- such as dropping a rock and observing that it falls to the ground even 100 times, does not prove that the rock will ALWAYS fall to the ground in the future; it does, however, support the hypothesis that something must be pulling the rock to the ground.
.
I am suggesting that anyone who wants to learn more about the movement of the sun and moon in the sky above, and is also interested to learn what our observations from earth can tell us about the relative distance from earth to the moon compared to earth to the sun, can find out the truth about these things by watching and measuring the angle between the sun and moon during the key phases of the moon: its first and last quarter.
.
Today is shown on your calendar as the day of the last quarter moon, April 19th, 2017. However, most calendars do not bother to mention the precise TIME of the day when the last quarter actually was at 100%. A very convenient reference for that time is the Old Farmer's Almanac, for those living in the continental United States and Canada. (The website does not process locations for other places like Europe or South America.)
.
Going to the Old Farmer's Almanac website, I found that the last quarter moon took full development at 3:00 am today in my time zone, and another page of the same site has the moon rise at 1:59 am. Therefore, by looking at the moon this morning at 3:00 am (it was low in the eastern sky) I was able to see the moon at its 100% last quarter time. This was interesting for a reason I had not expected to see, which is the fact that the angle of the dividing line between light side and dark side of the moon was not what I had expected to see. This kind of thing often happens while testing a hypothesis -- you observe something surprising, just by reason of your critical attention being paid to something that you simply did not take the time to notice in the past.
.
At 3:00 am I could see the moon all right, but I could not yet see the sun, so I could not measure the angle between the two bodies. I had to wait until 8:00 am (5 hours later) before the sun cleared the mountains near me, and at that time I measured an angle of 91 degrees. That was another surprise, because I had expected a lower figure. Later, at 10:00 I used a different method which I thought would be more accurate, and found the angle to be 89 degrees. Note: this was taken 7 hours AFTER the official quarter moon time in the Almanac. Since the moon's location in the sky is gradually getting closer to the sun this week, it makes sense that the angle would be smaller later in the day, but a difference of 3 degrees seems excessive. So my first measurement was probably questionable. I know this is not very scientific, but I'm using crude devices and there might be that much error in them. In any case I am very certain that the angle was not 80 degrees or 100. It was much closer to 90.
.
Two weeks ago when I measured the first quarter, I found the angle to be larger than 90 degrees by as much as 3 degrees. Still this is close to 90 and definitely larger than 80 and less than 100.
.
Therefore we are collecting readings that are very close to 90 degrees. I was hoping to have other readers mention what they have found, but no one has posted what the angle is they measured between the sun and the moon.
.
Once someone else posts then we can go on to the next phase. But not having any participation makes it kind of pointless to proceed.
