Modern day Flat Earth theorists still quote this experiment.
This practice included putting a pen at a collection elevation at either point of a channel around 6 kilometers lengthy. If the Planet is actually rounded, after that one pen ought to seem less than the various other when seen simultaneously with a telescope since the furthest pen will have actually dropped away along with the curvature of the Planet. However it was actually stated that the pens coincide elevation, recommending the Planet is actually really level. Modern Level Planet theorists still estimate this practice. Bad news for the ozone layer The issue is actually this does not consider the optical impact of the sky over the stepping in sprinkle, which flexes or even "refracts" the illumination as it journeys coming from the pen towards the telescope as well as creates it appear like they coincide elevation. The service is actually towards utilize several pens along the size of the channel which, when noted, all of seem at various elevations. Possibly one of the abs...
