when you're in a bus and it's driving along a highway you can get up and walk around comfortably

same goes for planes

even though they're moving pretty fast you don't feel the motion

cuz you're moving along with them

just thought of something

if you wanna test the fog theory

you could go nearish a mountain and look where it should be

even if its obscured by fog it should still block out stars behind it

unless it somehow also becomes transparent

@He Cute
1: the earth only accelerates relative to the sun as it falls closer and wraps around. when you're in freefall inside a plane you don't feel any acceleration, you just float, despite your acceleration towards the earth.

2: of course they don't block light, that's why distant stars can be seen on the horizon. the test would be to see if a mountain, a physical object in the way, would block out the light from those stars, or if instead the mountain is below the horizon and can't block that light.

well you could do a control

look next to the mountain

see if you can see stars there

where there's nothing obscuring it

also i didn't mention relativity, i just meant that objects moving relative to another object can still move parallel to one another

so?

maybe you see no stars either way

that's still a result

why would i have an image like that on hand

hiya

i was just proposing an experiment

i didnt claim anything

i proposed a method by which you could test which claim is correct

i'm not saying the air doesn't obscure light at all

i'm saying that might not be the reason why you don't see far away objects

also im legit curious of this

what purpose would a secretive world-controlling organization have for making people believe the earth is round?

also

when you look at the horizon you don't see it fading out

you see a flat line

a sharp line

why does it look like a sharp line when there's not much fog?

people are fairly inactive in the chats in this server huh

your point stands but smoke is actually a little denser than air at room temperature

it floats cuz when it gets created it's very hot

and since its a gas its density goes down

yea true

its opacity is largely cuz it has a lot of solid particles in it

this is pretty far off topic tho

helo

i mean it does

the atmosphere is fairly flat

stuff that's directly above you has relatively little air blocking its path

whereas stuff close to the horizon has a lot

hence why the sky is lighter close to the horizon

it's pretty damn bright

it's a lot easier to look at when it's that low

when the moon is low on the horizon it often looks orange

cause a lot of the light closer to blue is being cut out by the air

you'd still be able to say, see a strong floodlight pointed at you if you had a telescope though

if someone wanted to test that

like does it appear below the horizon when it's far away?

yea

well imo its cuz the horizon is the point where the earth's curvature blocks your view of distant objects like boats

though obv ppl on here would disagree

from your perspective at least

pretty much?

the earth's surface would start to get in the way and obscure it from the bottom up

so it'd appear to go down

ive commonly seen explanations that use like

lensing from the air

like a mirage

ive also seen some that just flat out say it doesnt happen but those ones are kinda dumb

though the mirage theory doesnt make sense

air above the ocean is typically less dense due to warm water vapor evaporating from the water heating it up

and if that's the case the boat should appear above the horizon

the air would need to be colder close to the ocean for the boat to appear to sink

well if you believe the earth is flat you probably also believe things about the moon

what are you

why do you keep repeating yourself like that

though i'd like to know why we wouldn't exist if it was a globe

yea that's a good point

how would it be impossible?

you ever seen chlorine gas?

how it sinks down to the bottom of a container?

it does that cause it's denser than air

and air just so happens to be denser than a vacuum

they actually can

you just need acceleration

yea

or if you wanna go really into it a curvature in spacetime but that's not really relevant right now

after a while the air from the fan will become equal in pressure to its surroundings

but as long as it's being accelerated it can have a pressure differential

i'm guessing the idea that it'd break the second law of thermodynamics is that it ought to spread out to reach a lower energy state

though that kinda

doesn't work unless you're ignoring gravity

or have some reason to believe gravity isn't real

over small scales yes, atmospheric pressure will force air into areas of lower pressure. but on a large scale the force of gravity can overcome the force of atmospheric pressure and create compression

of course you're gonna get large numbers, you're approaching zero

as you get a stronger vacuum you're just pulling out smaller and smaller amounts of air

it has a pretty negligible effect at that point

even with a complete vacuum the strongest force you could ever get is 1 atmosphere of pressure

because the pressure comes from the air outside

not from the vacuum inside

how does that relate to this at all?

why do you think that is though?

why do you think water flows to the lowest point?

in a vacuum there's very little air to transfer heat

so while the temperature may be very high the actual energy contained within that area will be low

uh
