The supposed calculation of curvature is 8 inches per mile squared but we never observe it anywhere

Nor does water curve

you said that you believe that lasers naturally curve, and specifically that they curve upwards over water, do you have any reason to believe in either of these points?

You can observe lasers curve upwards due to refraction

It must be leveled too

aside from atmospheric conditions that may occur sometimes, do you believe that lasers curve naturally?

If there’s no refraction then they do not curve

There’s been tests conducted by lasers where refraction does not happen

yes, in vaccum

not that you would know

so lets only talk about all the tests where refraction doesnt happen (because lasers dont curve in general, otherwise laser tests would be useless)

Dr John D has done some

on a flat earth the laser would go straight on ~~forever~~ very far with equal distance to the surface, while on a curved earth the laser would be closest to the surface in the middle of its path, do you agree?

No

why not?

Lasers have a limit

Lmao

They do not go forever
It would be cool tho if they did

That doesn't debunk @....'s claim at all

It wasn’t supposed to debunk is claim

If the earth is curved the laser would curve downwards yes
But we never observe it

Nor we observe or measure curvature

Here’s a laser bending up https://imgur.com/ZGxzT55

you realize that you have just some very poor quality video, because 99.99% of videos about lasers show them going straight, right?

Still proves my point
Quality does not matter

and why would a laser curve downwards on a globe earth?

I just told you
Scroll up

it proves the point that you are cherry picking the worst possible video and ignoring 99.99% of the evidence that disagrees with you

Not cherry picking bud

And prove 99.99% of laser tests over water have straight lasers

last time i asked you the question abut why lasers curve downwards you gave a statement about lasers going over the curvature (which doesnt normally happen)

prove it to yourself: google "laser video" and you will just see straight lasers

Show me 99.99% of laser tests over water are straight

im not gonna google for you and post the results here

Literally any test other than the ones you find inside of your flat earth social bubble will tell you

Most of the google results are YouTube video

thats fine

@.... burden of proof is on you
