Great pictures dyno!
I'm getting my camera repaired and I should have pictures of my experiment shortly as well.
It seems that these pictures do provide evidence that the earth is round. Would FE'ers agree with this? The only other explanation is the EA for FEers, which was just invented a few weeks ago.
Now how do we show whether it is the EA or the earth's convexity which causes this effect? What experiment can we do to tell the difference?
