we can safely assume that isn't glass though

for the fact that glass shatters

Where is the link for that source

hold on

I think I still have that tab open

page 2, section 4

Of what?

the pdf I linked to with the quote above

Your moving the goal post and it's driving me nuts

which goal post have I moved?

I had to prove their was no non linear deformation of the light

Now I have to prove that under static stress

If the deformation was enough to cause a sigficant and acknowledgable deformation to the light you would have died flying the airplane

I wouldn't say that was moving the goal posts tbh. there's the issue of the shape of the windows but additionally there's the stresses involved with the changes of internal air pressure to compensate for the changes to the external air pressure. it's not moving goal posts so much as the fact that there's other factors which need to be included

The other factors are negligible

And are therefore ignored

the document cited mentions the stresses as well as the myriad materials selected for the inclusion within the aircraft. but you do need to show proof of this neglibility

If they weren't negligible they would've included them in this beautiful source of you

Yours

as well as the proof to your claim that it doesn't cause distortion

I told you a simple experiment you could peform

That is proof

it has been said by others, possibly yourself, that curvature has been witnessed through aircraft windows, so, we need to establish whether that's as a result of these windows or as a result of actual earth curvature

your simple experiment uses the wrong materials and that wouldn't be very scientific

I was debating laws of optics

sure, but in any case, you haven't substantiated that

nor have you disproved that the curvature witnessed isn't the result of these windows

The light going through the window experiences a linear deformation

so you keep saying

without substantiating

You know what a linear transformation deformation is right?

Right?

Just send all flat earthers to space to prove it once and for all

it's where light passes through, it's transformed then deformed and presumably should result in lack of distortion

@positivity globe believers are the ones that believe space is real! send them all up there to prove the globe

Exactly

Therefore

No distortion

Means the earth is curved

well, so you claim! but again, you haven't backed up any of your claims! we've been over this countless times, I made claims, found documents, cited them, linked them and resulted in backing up some of my claims as well as providing other points which need to be considered, none of which you even mentioned or included within any of the explanations you provided, none of which substantiated. so sure, you make the claimm of linear transformation deformation, but you haven't backed that up, nor have you been able to prove that the air pressure change, and change in shape to the window doesn't cause distortion through the window. This is just one of many points that can be debated about flat earth, but I know this isn't a spinning ball we're all on.. This one small piece we're debating is just that: small! I know we're not on a spinning ball, so, with that in mind, any claims to curvature through an aircraft window, is not proof of earth curve, but proof of distortiion
