What say you all? You can keep on down-voting validated truth, but...



flat earth models are a lot simpler to work with during modelling and simulation efforts, especially during initial debug, but in the end if you want more accurate results you'd use a WGS84 or better model of the Earth which models it as a rotating oblate spheroid. The one linked paper I actually read also says it regards the vehicle as a point mass and that it moves through a nonturbulent atmosphere with zero lateral forces. It obviously isn't meant to represent reality...

I say this because I've done a lot of modelling/simulation work for various vehicle trajectories and during the debug phase you will usually start with a non-rotating flat earth just because the math is easier to verify

a crossroads can be used to summon a demon or devil in order to make a deal. This legend can be seen in many stories. For example, the 1587 Historia von D. Johann Fausten, describes the character Faust inscribing magic circles at a crossroads in order to summon the devil.

(1000m? whoa.) Tough question -- you covered all the routine factors -- then above and beyond. I don't have a clear answer for that East-West anomaly other than possible magnetic interference. (Might you be over-adjusting subconsciously for some unknown reason?)


My bullets are amagnetic. If I could adjust subconsciously and still shoot sub .2 MOA @ 1000m I would be a god.

Because I never really think about a flat earth I had never put them together until reading this thread but the spherical spinning earth explains Coriolis with high precision and accuracy.

Coriolis effect just doesn't exist at all. Snipers don't adjust for it. Water does not go down drains in a different direction in the northern and southern hemispheres, it's a fake meme it depends entirely on the original flow of the water and shape of the basin, you can make it flow different directions at your house. The bouncing a laser off the moon was done in the early 60s before the Apollo missions. These thing are reinforced in pop culture but they are not true, so why do it? They used to teach in America in the 80s and 90s that most of Europe thought the earth was flat in Columbus's day, and Columbus sailed specifically to prove it was round. But now they say that's nonsense and everyone knew it was round since the Greeks. The Greek notion comes from one guy Aritosthanes who did an experiment that is pragmatically impossible at the time measuring light in a well at two distant locations at the exact same time, and it assumes the sun's rays are parallel when not only can you look at the sun behind clouds and see they're not parallel but it's an observable scientific fact in all fields that sunlight converges and diverges, shadows bend. The radar argument gets brought up, see it has a limited distance because earth is round! But radar is a radio wave and can go across the ocean



When a round earth theory is shown faulty they just move on to another attack. The truth is there is no proof and it's mostly group dynamics. People will literally deny reality if the group thinks they'll be called crazy/stupid. This is exploited and they teach this from a young age.

Literally every single round earth notion can be disproven, is unproveable, or shown to be an absolute lie like NASA Photoshop. However flat earth can be proven by you yourself. You can do the geometry for how curved it should be or use this website

earthcurvature.com

Round earth is based on the assumption that earth is vast the vastness provides a de facto flat earth. But the math doesn't work. It should be noticeably round. Our modern optical devices have surpassed the idea.

For example at 50 lateral miles the earth should curve over 1600 feet downward. Get a camera, something you know is 50 miles away on a plane or the ocean and see it. Not curved. Period.

Are you gonna be honest with yourself or be scared of being belittled?

So this prompted me to go down a YouTube rabbit hole and I found this video. The way this guy presents his info made me laugh pretty good.

care to comment on this?

Saildrone is first to circumnavigate Antarctica, in search for carbon dioxide

quote:

On August 3, 2019, an unmanned Saildrone 1020 completed a 13,670-mile journey around Antarctica in search of carbon dioxide. It was world’s first autonomous circumnavigation of Antarctica.


or is this just fake government propaganda?

Sure. Put things down on your flat floor to represent continents. You can walk in a circle around them.

Put a big blanket circle around your continents. Walk inside this big circle.

Do shadows from spheres always cast circular shadows?

I typed a long post. You ignored 95% of it and moved on to another attack like I said you would in the post.

THE frickING EARTH IS NOT CURVED. YOU CAN SEE THIS YOURSELF.

How does not stop you right there and say holy shite. You have nothing to say about that? Everything you know is a lie. Go fricking see. Then you can look at other lies

Are you positing that it’s not because I can’t see curvature from using my own eyes?

Bull fricking shite. Coriolis affects every shot but is normally only compensated for out past 400m. Every good long-range shooter absolute knows this and has seen it. Every ballistics computer takes this into account. It varies by latitude and that has to be taken into account just like the direction of the shot in terms of cardinal directions and whether you are in the northern or southern hemisphere.

It is odd that the ballistics math just happens to line up exactly with the spinning round earth model.

YES. You think it's so big you shouldn't be able to see it. You have not actually done that math and tried to see it. Do the math and see well past where it should be curved thousands of feet down.

It's simple geometry. We know distances. The distance of the "equator" tells us how curved a spheroid should be over any distance. It turns out if you do the math it's a lot more curved than your common conception of it. It should curve over 60 feet every 10 lateral miles! That's ridiculous! You can see the ground and the water, everything further than that on a plane or the ocean, when so much SHOULD be obscured past the curve.
