Well the point is that he did not have anything to say in response to the 500 ft contention, and it is a pretty bit contention!
As for your uncles place, this does not have much to do with this video. The reason you see more when you go up is simply because you have a greater perspective of the flat earth. The point of the video I posted is to show something that is physically impossible according to the mathematics of the globe earth. It completely undermines it.
The same is illustrated in this video
Well, if this video illustrates the same thing... we have a BIG problem. Now, If I honestly have to go by what is seen, the water and other scenery looks like it's curved in the video when he's using the binocular/telescope/zooming device (whatever it's called!) to view the tower. It seems to me like one is looking up hill. The next problem is that at the end of the video he admits it could just be refraction. There can't be a definitive answer/result when there is still an impedement, and that being the refraction.
http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/refr.htmlAs one who suffers not having 20/20 vision, I can tell you from first hand knowledge that the wearing of some glasses can make the ground immediately in front of you appear to protrude as though it were a hill, creating an illusion. So, while refraction is still a possibility - especially since he is utilising more then one lense - this material is not good enough for me, so I reject it as insufficient of accuracy and certainty.
