thats all indirect evidence, direct measrements have been performed and the measurements tell us its flat,

No they havent

I can directly measure the horizon drop with altitude

no you cant

Lol

You don't understand math so your response is expected

i havent seen any math coming from you

lmao

I can use a theodolite to measure angles, easy

Refraction typically bends light down

aww ur gonna get a theodolite the in the view things will get smaller how does the theodolite account for things getting smaller in the distance

@Shabam I accept your measurement of your angles. Please prove lasers curve down in air.

it doesnt

@jeremy it can measure their angular size

Or angle between objects

so the theodolite knows things get smalelr in the distance ?

perspective

It's not a person it's just a tool

so the theodolite cant account for things getting smaller in the distance

Sure it can

how

Zoom

It can measure angular size if you want

But I don't need it to do thay

oh ok

I just need it measure angle of horizon below horizontal

The air temperature is always going to decrease with elevation, although by varying in rate. Light will always bend towards the more refractive medium.

Cold air has a higher refractive index than warm air

Wrong, typical refraction is downwards

@Shabam Please show me a laser curving down in air.

typical, ignores direct measurements bases his proof on indirect measurements and helio cult religion

sheeple u my best friend

could it be the theodolite is measuring an illusion ?

The theodolite is measuring an angle of light

the light curves up

or everything that happens at the horizon is a fact and is exactly how we see it ?
