This is pretty cool!  I hope more people, especially Flat Earthers, will watch this...

Indeed.  I appreciate the time that the user took to explain his maths.

It does not have to be that complicated. 

I appreciate the geometry but there is an easier way to convey the same arguments.  All you have to do is take a straight-edge ruler to a desk globe model of the earth and look for contradictions to real world observation.  You can do it in a dark room with a torch-light if you want to create a dramatic effect.
