Answering a post that is less than 3 months old is frowned upon now?I thought that archeology was your game.
You seem to be stalking me.Am I going to need a restraining order?
Am I still banned?
Nope
The extra angle in a triangle drawn on a sphere is well know in geodetic surveying as the Spherical Excess, but is simply not the thing any ordinary person can do!Do you understand the concept of scaling an experiment?You do realize that if this is done on a small scale, you can not make a triangle, whether the Earth is round or flat, right? If you don't believe me, go to a park, walk 100 meters, turn 90 degrees, etc. and you will not have made a triangle.What is there to disprove? You posed a hypothesis. If the Earth is round, your hypothesis will be correct.It has been done, but on a smaller scale, but the logic is the same on the earth (If perfectly round).
Go ahead. Perform your experiment.
I propose to you (Flat Earthers) to disprove it. Explain why I couldn't scale it up and/or explain why my experiment was false or what ever your idea may be.
In reality, this is just a thought experiment. If the Earth is round, then this is what you would expect to happen. This does not mean that it has ever happened. Yes, you can do it on a beach ball or something, but who cares? It has never been performed on the Earth. Frankly, I don't see what this has to do with the Earth, or why you think we are so ignorant about geometry that we would try to mathematically or otherwise try to disprove this.
Say the size of a large sphere is 20,000 units and it spins at 1,000 units per hour.
To scale that experiment down, let's say 1/10 scale, the smaller (scale) sphere would be 2,000 units and the spin would be 100 units per hour.
From the original post the distance traveled would also scale down proportionately to 1,000 units.
This is the way scale works. All parameters are treated to the same scale factor. Your example above is not equivalent to scale modeling.
The excess angle is simply:see a long winded article in https://en.wikipedia.org/wiki/Spherical_trigonometry.720° x (area of the triangle)/(surface area of the sphere)So the triangle with 10,000 km sides is just one eigth the total area of the sphere, so the excess is 90°.
"On the Earth the excess of an equilateral triangle with sides 21.3 km (and area 393 km2) is approximately 1 arc second." same article.No, unless are surveying very large areas, forget this as a practical test!
Just to conclude, TayIrving on April 28, 2015, 09:03:15 PM says, "but who cares? It has never been performed on the Earth" is simply not correct. It is just a standard part of Geodetic Surveying, just look up http://civilengineersforum.com/geodetic-surveying/.
Rephrasing the original question a bit:My friend is flying this route later this week. I'll get her to take some photos of "the wall" for you.
When using the FET, why would an aircraft, flying fom Buenas Aires to Sydney, fly away from Sydney, i.e. fly approximate in the direction of Antarctica? Why don't these flight always end up crashing in the big wall at the 'edges' around the flat earth?
Regarding flight time, it's only about 14hrs or so so this puts doubts to the FE theory, or at least the map!!
