waykiwayki (Mark Knight) deletes important comment thread to hide his ignorance
Dear waykiwayki (Mark Knight),
Fact check = You FAIL
For once again deleting comments that you deem as unfavorable (see print screens below). That shows you are a hypocrite and afraid of an honest challenge to your flat Earth positions.
You never addressed:
a) finding no curvature does not prove that the Earth is flat - even a flat Earth has curvature
b) finding no curvature does not prove that the Earth is flat - because you are ASSUMING there are only 2 alternatives for the shape of the Earth (flat or globe).
You never addressed how high one really needs to go in order to see curvature:
With regard to curvature not easily seen at the elevation of a high altitude balloon (say 130,000 feet), the presenter is correct. Just do the math yourself and you will see...
At a height of 35,000 feet above the Earth's surface you can see a curvature of 3.3 degrees.
At a height of 100,000 feet above the Earth's surface you can see a curvature of 5.6 degrees
At a height of 200,000 feet above the Earth's surface you can see a curvature of 7.9 degrees
At a height of 300,000 feet above the Earth's surface you can see a curvature of 9.7 degrees
So even at 300,000 feet you need a wide panoramic view (180 degrees) so see curvature.
You never addressed:
The fact that even a flat Earth has curvature, and can be seen at some high altitude.
You stated:
"One can see 200M high mountains in Africa from Marbella beach on a clear day.....85 miles..........not possible on a spinning ball."
Correct answer is:
If you are referencing Marbella, Spain, which is 1,476 feet above sea level, for a person with eyes 6-feet above the ground, at a distance of 85 miles, any mountain would need to be at least 955.7 feet tall (291 meters) in order to be seen.
Your answer of 200 meters is incorrect by 31% for a globe. But that is acceptable.
However, for a flat Earth as long as there is no line of sight obstruction, you should be able to see all the way to the edge, and you are not able to do that.
With regard to the math question:
So what is the curvature drop at 103.257 - miles distance, and how high does a mountain need to be in order to be visible from that distance?
Your answer was:
"well over 1km.....from memory it's over 2.5km......but my days of going with globeheads is pretty much over amigo - it's not a maths issue - it's an IQ issue. Show me one photo of earth from space?"
Which is fairly accurate:
For any mathematical sphere that has a diameter of 7,918-miles (same as the Earth), for a person with eyes 6-feet above the ground, any mountain at 103.257 - miles distance would need to be at least 6,708 feet tall in order to be seen.
6,707 feet = 2.04 km
The curvature drop at 103.257-miles is (1.35 miles, or 7,111 feet).
However, your assertion that it's not a math question but an IQ question is wrong. It's strictly about the math.
Math is math, and where you learned it does not matter.
Summary:
So you fail for not being honest with visitors to your channel.
After this exchange Mark Knight banned Michael Chranston and others from future posting on his channel.

Additional delete on August 25, 2017, when we presented instruction for an easy experiment that anyone can do, to find out for themselves what the shape of the Earth really is.
An easy experiment that you can do - that proves the Earth is a round rotating globe
