Lack of curvature proof experiments - Lasers etc

Another proof is the more precise measurement of the curvature, (or rather lack of) the earth. Many have been done using flags (Bedford level experiment ) and now in the modern day with lasers. Feel free to start threads on this topic here also.

PART 1

Is a video showing how lasers proof the flat earth. There is some mild male immodesty when the video is embedded, so I wont do that.
The second part of the video is here



PART 2


Note: The goal of this experiment was NOT to proof the flat earth as you will see in the video. But it proved it anyway.







It is important to note the objection of refraction which can be given to this and the bedford level experiment especially.
This objection is absurd when one reflects on it. The claim is that the light bends perfectly around the curve of the earth. The response is that while this could happen, the image is blurred, and in the case of a mirage is inverted. To have a clear, right way up vision of the object is not possible.


Two excellent videos showing what superior mirages and refraction ACTUALLY look like are below

Another video of a laser test.

Unforunatly, this one is done at night time and there is no way for the viewer to verify where the person is.

WARNING, there is a heavy promotion of protestantism at the end of the video.
