Simple logic is what I'm using.
You might think you are, but to any sane person you are just repeatedly throwing logic out the window.
There is nothing level about what's in that diagram.
Really?
Because you were claiming the black lines you added as the level sight from the boat and a level sight from the lighthouse.
They would be a level sight from the boat
Thanks for admitting you are just being extremely dishonest.
This shows you KNOW that on a RE, level is not the same direction everywhere. Instead it is based upon location on Earth.
That means a level line, which is level everywhere along it on the RE WILL CURVE!
That isn't difficult to understand.
So why do you need to continually pretend to not understand?
And no need to dishonestly pretend you are getting confused over level in your fantasy, vs level in reality/the RE, as you were clearly trying to describe level for the RE.
And the same kind of reasoning applies to plumb lines.
Tilt is tilt. It is not level and would increasingly build over distance.
Your globe is absolutely nonsensical.
And as your previous admission has shown, this is just more dishonesty from you.
You know the globe makes sense.
You know that level tilts as you move around the globe.
This means 2 level objects in different locations will have that level tilted w.r.t. each other.
Likewise, it means any 2 plumb lines in different locations will be tilted w.r.t. each other.
There is no contradiction or problem for the globe.
Again, my simple diagram shows that is the case for anyone honest enough to actually think about it.
The tilt discussed regarding the towers is purely due to the curvature of Earth making the 2 plumb lines tilt w.r.t. each other.
It seems to make sense for anyone, except those with an irrational hatred against it, who decide to repeatedly lie to pretend it doesn't make sense, even though they cannot show any fault with it.
The RE not being the FE, and not following the incorrect claims of the FE does not mean it doesn't make sense.
For a RE it is quite clear what level and plumb mean, and the simple fact is that their orientation depends upon your location.
8 inches per mile squared tells you all you need to know about whether it's hardly noticeable.
Yes. A mile is 63 360 inches.
So for 1 mile, that drop is 8 parts in 63360, or 0.01%, practically nothing.
For a shorter distance like you suggested before, 1/32 of a mile, then that is 1980 inches for the distance and 1/128 inches.
That is 0.0004 %, even less, and practically nothing.
So yes, as a measurable drop, it is hardly noticeable.
If you would prefer it as an angle, then for 1 mile, you have 8 parts in 63360 which equates to an angle of 26 arc seconds, again, hardly noticeable.
So perhaps you should go away and have a word with yourself.
