You are definately the one spitting bullshit...
"Empty space is a shape"...
"The earth is flat but has no edge"
"Gravity doesn't exist"...
Give me a break. Definitely you... And I'll tell you one thing... The only reason I'm here responding is for entertainment.
As soon as you get boring I'm done and i'll stop responding to you, because I'm not putting in real work to refute bullshit.
So can I ask you just straight up... Do you have a way to measure the levelness of a laser beam to an accuracy greater than 1/1,000th of a degree?
Cause I'll accept your experiment as valid if you can, but then you must also accept it as valid when it measures a drop.
You most certainly did not explain it...
And it most certainly does matter... If you can't guarantee the levelness of the laser any measurements you take on the other side are invalid.
And I swear to god... if you respond with "nuhh, uhh I did explain it" and you don't link to your previous comment, you're getting blocked, cause your entertainment value is out the door when the annoyance factor reaches a certain level.
My point is were onto like the 3rd or 4th proof that the earth is a sphere.
If you get that laser perfectly level, I will accept your experiment and it will prove me right.
Show me what instrument they used to gauge the levelness of the line then.
Water is not a level.... Much less an open body of water with wind and waves.
Give me fucking break. That's even more retarded than thinking the earth is flat.
No, it's not within the margin of error at all.
Let's do the math...
https://www.calculator.net/triangle-calculator.html?vc=&vx=2&vy=&va=90&vz=126720&vb=&angleunits=d&x=Calculate
Angle A = 90 degrees (the target standing vertically)
Side B = 2 inches (a desirable margin of error)
Side C = 126720 inches (2 mile distance)
Result: Angle B = 0.00090429. (the angle of the laser on the 1st bank)
That means for roughly every 1/1,000th of a degree that laser is off, the dot on the other end will be 2 inches higher or 2 inches lower.
That's a range of 4 inches. That's an acceptable tolerance.
But the most accurate construction levels I could find boast an accuracy of 0.029 degrees. https://vinatools.de/70-nivo-spirit-levels/
So assume you use that tool and it tells you that the laser is level...
But really it's 0.029 degrees off from true level....
Now lets plug that info into the triangle calculator, and see what our margin of error becomes at a distance of 2 miles.
https://www.calculator.net/triangle-calculator.html?vc=&vx=&vy=&va=90&vz=126720&vb=0.029&angleunits=d&x=Calculate
Angle A = 90 degrees (target standing vertically)
Side C = 126720 inches (2 miles)
Angle B = 0.029 (the margin for error when using a construction level)
Result: Side B = 64.13876 inches (the margin of error you will get)
That means if the laser is off by just 0.029 degrees it will be 64 inches higher or 64 inches lower than your desired target.
That is a range of 128 inches that you can expect to be off in either direction when using a construction grade leveler.
And while you are at it... Go ahead and tell me why my long distance version of the exact same experiment DOESN'T work.
Even though you don't need to hold the laser perfectly level in my version and just need to verify the light is visible at any point.
That ought to be entertaining.
It's literally the exact same as your experiment except it's far enough away that you don't have to care or measure the exact angle of the laser, only whether or not it's visible.
You make the target a camera lens instead of piece of cardboard.
No ultra accurate leveling device is needed... Just repeated moving flashes in a general direction that can be done by hand. And you either see the flashes from across the lake, or you don't.
At a distance of 200 miles on a curved earth the light would not be visible... But on a flat earth you should still be able to see the flashes even if only briefly...
Record even one flash from that distance and you win...
