It's called mount Meru

Otherwise known as the cosmic mountain

Your getting closer to interesting answers

I already knew all of this

Here let me show you the parallels between mount Meru and the depiction of the world you just gave

hold on

i cant find anything to do with or proving flat earth under "Mt Meru" or "Cosmic Mtn"

I'll send it to you in a dm

there is 7 measurements done in 2 countries

Surface tests for convexity using a laser transit

im reading

Okay I explained that

You will find that to be universal imagery

Along with a symbol of a plus sign

Representing the sides and center

It's in all cultures

The same story told over and over

Even modern history repeats it

It also turns out to be the symbol for Atlantis

(I wasn't joking when I said I was the world's greatest detective)

You should also know that evil cults practice a darker version of the same belief

They place the symbolism everywhere. Masons at work

Part of a larger evil cult

That puppet and munipulate the world

earth is flat

The laser used by FECORE was never demonstrated to run parallel to the water's surface, across the entire target span.

In slide 13 they state:
"the laser beam was adjusted parallel to the water surface using the horizontal line and visible city light on the opposite shore as reference."

This alone invalidates all of FECORE's math and conclusions, because their laser beam was not parallel to the lakes water line.

---------------Every laser test past the primary horizon (2.85 meter laser height reaches the horizon at distance 6-km) has to contend with light bending, beam expansion and distortion from multiple effects, such as:

turbulence (rising and falling air currents, and the offshore breeze that all sailors know about)
thermal layer ducting
thermal boundary layers
thermal blooming
evaporation duct height
atmospheric looming, sinking, towering & stooping
inferior mirage, superior mirage, and Fata Morgana

-----------Snell's law of refraction is not valid for atmospheric calculations

------Basically, this experiment suggests that diffraction is real and doesn't show whether the earth surface curves or not.

@indio007 this "experiment" is CR4P

ninjamaster's rebuttal is pretty solid

@indio007

@NinjaMaster I didn’t just give you evidence earlier, I gave undeniable proof.

I don’t think you know what proof requires. Ball earth doesn’t have any.

@Derek Nelson does a light bulb emit light or suck darkness
