So I wanna know from flat earthers, how do you still hold on to your idea, after last year's space live video stream from the launch

How is flat Earth still a thing after the live video stream from spacep

That's exactly what they were looking for, and they got it.

Thx

If earth is flat how do we have the ISS in orbit

You can see it yourself with a telescope

Typical

@Citizen Z I like when. Flat earther go I to this territory, saying g things like math is the reality

@TiredGiant we can help them

Hey I was talking to him.

That's rude

I do

Bummer

K,. What is it you're looking for

Which link

Ok I have it

Here it is

Why do shadow angles at different latitudes follow a linear pattern, rather than a nonlinear arctan function?

Well ya but I'm not talking about that

I'm talking about shadow angles taken at the same time of day, at different latitudes

Like local noon, in the equinox

The pattern of shadows angle vs distance from the equator, if you plot that data

Hehe nice bot feature

What do you guys think of the photos from 100 miles up, from the 1940s?

😛😛

No the ones from v2 rockets, looking at the earth

Pretty clear right

@Deleted User what's that spirit level calibrated to?

How do you know it's straight within a millionth of an inch

@Citizen Z did you check out that eratosthenes data

@Citizen Z but measurements are from today

Eratosthenes.eu

@Citizen Z doesn't matter your personal opinion of the ppl. It's still measurements that eliminate the possibility of a flat earth

You can do these yourself with friends

There's good reason to

What rule did he break

@Jatsko @Dawn @Deleted User the vendee globe sailing race goes west to east around the south pole and they have to turn right to stay on course

that wouldn't happen on a flat earth

gsus this is child abuse

@Deleted User if i have a helium balloon in a car, when i accelerate, it moves forwards

does this mean the earth is accelerating upwards, making teh balloon go upwards?

why doesn't it go sideways

relative density exists in that direction too

what if we modify only the pressure gradient in the water, and don't change densities at all

@Deleted User in the balloon car example

neither density changed, but the balloon started accelerating faster than the car

how could that be

how, it's the same amount of air, in the same volume

and density is mass/volume

Does the pressure of the air also change in this case?

so it could all be due to pressure and not density

need an experiment with a proper IV

right now you don't have one to support your case

according to the KMT of gases

so this experiment suggests the pressure gradient exists in our atmosphere due to acceleration

ya but temperature gradients don't cause a pressure gradient, in a contained volume of gas

no sorry that would violate the 2nd law of thermo

freezing air is not a temperature GRADIENT

ya but those gas molecules are not prevented from mixing with all other molecules in the volume

yes that's true

but that's not the same as a temperature gradient

take a vessel of air

heat the whole thing

pressure goes up

heat just the bottom, pressure goes up evenly throughout it, just not as much as if you heat the whole thing

no that wouldn't happen, b/c the gas molecules are free to mix and equalize pressure

you can't have a pressure difference without a barrier between them

same argument you make about earth's atmosphere

back tot the topic

tell me why you think you can get a pressure gradient, in one container of gas

please describe waht you're saying

i didn't say you did

i said atmosphere

which is teh gas we live in

what do you call the gas volume we live in

ok taht's not a scientifci term

you'll have to write your own science book if you wanna use that

i'm using the accepted terms

no don't change topics

we're talking still about pressure gradients

you said a temperature gradient creates a pressure gradient

in what situation

let's see the experiment to back up your claim

ok

where's the pressure gradient

lol

no it's the 2-phase refridgeration cycle

joule thompson effect, maybe

but that's just isenthalpic expansion of a gas

nice

ok where's the temperature and pressure gradient

ok cool, that's not what's happening in the refridgerator

b/c that effect is for isenthalpic expansion

you took out the expansion valve/

why
