Flat earth gets downvoted like no other. This is literally the mother of all conspiracies. Mix of Deepstate troll farms and heavily indoctrinated Normies who can't see through the lies. That is all.
FE or Globe Earth is Hegelian Dialectic to distract people from the idea that the Earth is Hollow and Growing. Pick a side, but don't fly too close to the flame. TPTB divide and conquer. Truth is always stranger than fiction.
It's definitely flat as in level at the ocean
It's not flat, what you are seeing is a Earth larger than what they say. Look into the two theories and run the math. That is why we can see ships zoomed in which shouldn't be visible because of the "curvature". I know only a handful of theories that get ignored out right, and Hollow/Growing Earth are one of them. For example, another one would be the Venetian/Black Nobility. Rothschilds on the front page of /r/con, but, if you talk about House of Aldobrandini, an ancientHouse they had to wait a few hundred years to marry into... You get crickets.
Anywhoo, happy rabbit hole falling....
Well poisoning level flat earth. Laser pointer tests 22 miles no curve.
Lets say it were even US nautical miles. It gives about 40 km. Let's assume you are neither lying nor trolling (but I suspect you are rather troll than so big idiot): the difference would be about 36 cm (~14,18 inch !)
As I am engineer with a degree I know something about lasers. You probably wouldn't afford to buy high coherence laser which would be coherent enough on the distance of 40 km to measure such thing ! And you didn't bought it - you just said "laser pointer" ! Laser pointers are at best coherent over 100m, maybe few hundred meters at mximum - so much less than on mile ! Not to mention keeping laser pointer in hand (fuck - even if it would be laser level which are useful in building buildings not scientific measurements) wouldn't allow to even get ideal horizontal position to measure anything. More than 1 km and that "laser beam" would be like flash-light (still maybe dangerous) rather,so forget exact results. Your "measurement" was completely shitty.
And my answer is rather not for you,because you are stubborn idiot or troll.
