If your Earth curves then, given that you people argue for a curve on clear water level to any rational person, then you also have to suggest there is a hump in the centre of the lake in the diagram I made.
And if you had any sense of integrity you would note that the hump would be a mere 3 mm, and thus in no way visible on that diagram.
The centre would be all of 3 mm higher than the start and end.
But that is for a level surface, not a frozen lake where the elevation could easily vary by far more than 3 mm.
Because, according to you people your Earth supposedly curves and if that is so then your water/ice should be curving up to the centre from both positions from each end of the markers and string line.
No, from the centre it would be curving down.
Curving up implies it goes to a peak, not a round, continuous curve.
But even then, it isn't actually getting higher or lower. It is level.
And, if the 201 metre string line did sag it would go in your favour
There is no IF, the simple fact is that it will sag, and unless you have amazing material properties, that sag will be more than the drop due to the curvature of Earth.
This shows you haven't even attempted this experiment, as if you did, you would conclude Earth is round.
It would not show Earth is not round.
But you admitting that it goes in our favour shows your diagram is BS.
Ohhh and by the way, the 201 metres is 1/8th of a mile.
Which means the drop will be 1/8th of an inch. i.e. 8*(1/8)^2.
The drop you are trying to look for is tiny, well below the experimental uncertainty.
But with the experimental setup you have, you aren't looking at the centre for an increase in height.
Instead you are looking at 1/4 and 3/4. That means you are down to 0.8 mm (roughly 1/32nd of an inch). Nothing like the half inch you claim, and it is in the wrong direction to what you claim.
So yet again you appear to just be pulling numbers out of your ass.
10 out of 10 for desperation.
You do seem rather desperate, but that is normal.
