Your arms would be resisting the constant air pressure. A column of air 1 square inch in cross-section would have a weight of about 14.7 lb or about 65.4 N.

So you have almost 15 lbs of air pushing your arm down per inch, even if your tiny arms are only 2 feet long and 3 inches wide, thats 540 lbs of air pressure.



So if I put on a sombrero with an area of ~6 sqr feet I will be crushed by this column of air?

That's exactly what he's saying.

your language is so puzzling i don't understand what you're even asking for. perhaps if i understood what you're even asking for i could answer. but as you just keep mixing your own unproven views in with unknown to me situations i can't even respond.

you just keep saying things like "2d side view" and "horizon is always less than 90 degrees" and " the horizon is just 360 x your stupid idea of perspective"

none of those things mean anything to me as none are correctly using technical terms. im sitting at a computer this very instant working on a 3 dimensional drafting software in which i just drew a MASSIVE sphere. then i zoomed in tilted my view and slowly rose. whoa, would u look at that, the horizon of what i can see on the sphere appears flat. whoa.

you can't acknowledge this because it puts a hole in your theory that not even buzzwords can argue. which is why rather than addressing my facts you're trying to deflect by claiming i don't understand perspective. Lucky for me i dont have to mentally conceptualize it, i can literally build a 3d model right in front of myself, if i had any vid capture software i'd be happy to make you a youtube video but i dont sadly.


Maybe the reason is that your not doing it correct, you wouldn't tilt your view - you would rotate the sphere 90° so your view is completely parallel to the subjects view of that point where he sees the horizon and place your own eyes right next to the "stick man".

I wish i had a video camera and a globe, but i look forward to your drawing in the meantime.

This is not the way air pressure works, it is pushing down of each point so its force is not cumulative but it is consistently their and providing equal force on each point, you just dont see it.

and air pressure is only part of the reason , you must consider the density of the object as well as the density it exists in. Density is not just mass x volume - Density is also the vibration intensity within a
volume in relation to the density of the surrounding medium and the changes in magnetism, electricity and temperature.

But if you dont understand it - just go with the Gravity thing, that's why it was invented.

Must be some superior Mexican engineering to prevent sombreros from collapsing under all that weight.

Don't have a ball and smart phone?

i don't think you understand what's going on at all. i'm not looking at the model through some outside view, i didn't draw a stick man.

i drew a sphere the size of the earth, picked a point on it at random, and that became my view. then i can just punch in numbers of where i want myself to be at and move around. i can change my elevation which increases my view of the horizon. essentially i'm doing exactly what any person can do to collect raw observable data but with the ability to raise in elevation at the click of a button and take actual measurements of what i can see.

Well if your tilting your view - you're not being true to the observers perspective - unless you think your God.

I'm pretty sure your doing it wrong.

tilting my view = looking around

do you have a neck cast on that prevents you from tilting your view IRL? i can assume a 1st person perspective.

sounds like your trying to figure out why the horizon is actually curved in your model and you're trying to figure out how to make it look flat. :rofl:

No, you won't get crushed because of perspective. You would only get crushed on a 2d world, but you have to consider the z-axis. Thanks to perspective, air pressure only affects people's arms, not sombreros.
