Why you need to ask me this is absolutely beyond me...it really is.
Have you ever used a spirit level to level anything up?
You said you only needed the tube.
Now you are saying you need a spirit level as well.
But surely you know that if you want to use a spirit level you should be using a flat base, not an easily deformable tube.
Again, why not take the simpler option of a water level?
That way no external cross hair is needed.
Most of what we're told is based on anything but, fact.
You mean most of what YOU tell us is not based upon fact.
What mainstream science tells us is typically fairly accurate and factual.
So....as for me having no clue. In your mind you're right, from your perspective, because you do not follow anything other than the global given, so I understand you being trapped in that.
Stop just repeating the same lies.
We don't just accept what we are told. We also accept evidence, the kind of evidence you dismiss as fake or cheating or just outright ignore because it shows you are wrong.
We also have logic on our side, unlike you who just ignores any logical argument that shows you are wrong.
What is clearly observed is that the horizon is not the convergence point.
Then you stick to that. Anyone can prove it is.
You mean like all those photos that clearly show it isn't?
Anyone who honestly examines the evidence or gathers it themselves (at least if high enough) can clearly see that the horizon is NOT the convergence point.
It's not about me having to prove anything or you denying it.
I'm not the one in denial.
I'm not the one repeatedly denying reality just because it shows I am wrong.
That is you.
Anytime evidence is presented which shows you are wrong you just dismiss it or ignore it and continue to repeat the same lies.
You don't have to prove anything. No one can force you to prove anything.
What it is about now is how your blatant lies are directly contradicted by plentiful evidence and logical reasoning and how you have no response except dismissal or ignoring it.
You are unable to show a single thing wrong with this evidence.
It is also about your extreme dishonesty, where you claim that you would admit if you were shown to be wrong, but then show just how much of a lie that is when you claim you will refuse to accept anything about the horizon if you don't already believe it.
The experiment is easy to do and it not only shows the convergence point
Yes, the experiment is quite easy, and there are many ways to do it.
And it conclusively shows the horizon is NOT the convergence point.
Yet rather than accept that fact, you just keep on repeating the same lies.
it also shows Earth absolutely 100%, cannot be a globe we supposedly walk upon due to this convergence point
How?
The horizon is not the convergence point so it shows nothing of the like. The experiment is 100% consistent with the RE and quite firmly refutes the FE.
If you wish to claim otherwise with even a shred of integrity you need to actually deal with the evidence which shows that the horizon is not the convergence point. Otherwise, every time you repeat this same lie you are just showing everyone how dishonest you are, how you do not give a damn about the truth at all and are quite happy to repeatedly lie to people to pretend your delusion model is correct.
Grow up. Start dealing with all the issues raised.
Now again, care to address the issues:
Why haven't you explained how GPS can work with instantaneous light?
Why haven't you pointed out a single problem with my argument for the RE having a horizon which would be basically indistinguishable from "eye level" when you are close to Earth? Why do you instead repeat the same lie that a RE wouldn't have a horizon?
Why don't you explain why the horizon is clearly observed to be below eye-level from a high mountain?
Why don't you explain just how the "flat" water magically manages to obscure an object that is above it?
Why don't you explain how your alleged flat water works on your alleged bowl Earth to produce the oceans, rather than as in my example image where it completely floods the lower regions while leaving the top dry?
Why don't you show that you can fit anything to anything, by fitting a triangle to those 9 points?
Why don't you provide evidence of your allegedly flat water rather than just repeatedly asserting that water is magically flat?
If you want one which is not based upon evidence at all and instead based upon cold hard math and logic, then deal with the existence and location of the horizon on a RE, including how it is basically at eye level when you are close to the surface.
You are yet to provide any rational objection to the following line of logical reasoning that shows beyond any sane doubt that YOU ARE WRONG!
1 - Looking down you see ground/sea, i.e. EARTH.
2 - Looking up you see sky.
3 - That means if you started out looking down and slowly raised your head, your would see some kind of transition between ground/sea and sky.
4 - Assuming there isn't anything getting in your way, this transition would be a line; below this line you would see ground/sea and above this line you would see sky.
5 - This is just like if you look at a basketball. You can see a line, "below" this line you see the ball, "above" this line you see the surroundings.
6 - This line would be the horizon for a round earth. So now the question becomes where is this line?
7 - Simple trig shows that the relationship between this angle, as measured from level, the radius of the ball, and your distance/height from the surface is:
cos(a)=r/(r+h).
8 - Doing the math for a RE when you are 2 km above it shows the horizon would only be 2.7 arc minutes below level, i.e. imperceptibly different from level, and entirely consistent with what is observed.
9 - Thus your claim for why you think Earth is flat is pure garbage.
Yet rather than admit you are wrong, you just completely ignore it and just bring up the same refuted lie later.
If you can't even point out a problem with that line of reasoning or admit you are wrong, then it is quite clear that you have no intention of ever admitting you are wrong on something like this.
Then once you manage to do the impossible with that, you can do the same with your outright lie that you can fit anything to anything, by either admitting you are wrong with that claim or by fitting a triangle to those 9 data points (and point out what is wrong with my argument as to why that is impossible).
Then you can explain how you manage to have a flat water level on your magical bowl Earth that actually matches the observed oceans rather than flooding some areas of land entirely and leaving regions of oceans completely dry.
Try to actually address the issues rather than just ignoring them or strawmanning them or just repeating the same lies.
