Umm idk if you guys realize this but Earth is really big

really? how big? what is the diameter?

So it’d be hard to capture the entire Earth in one photo

12,000 km

how was that diameter determined?

Placing 2 wells 800 km away from each other

When the Sun rises, it’s light reaches the well at an angle of 7.2 degrees

and what assumptions must go into the calculation?

A sphere is 180 degrees so

180 degrees? a sphere?

so 90degrees is a half sphere?

and...are you saying that one assumption that goes into the calculation is that earth is a sphere?

360 sorry

lol

oh. so one assumption that goes into the calculation is that Earth is a sphere?

and the sun?

what assumptions about the sun?

Do you understand geometry?

can you please answer the question first?

One one well was illuminated at a time, once a year while the Sun was directly over head

but you agree that one assumption is that Earth is a sphere, correct?

On a flat Earth you’d expect both wells 800 km away to be lit up at the same time but it was not

yes or no?

It’s not an assumption, the angle of incidence showed that Earth was a sphere

that is not true

and you know it

what assumptions must be made regarding the sun?

do you know?

7.2 degrees is about 1/50th the arc of an entire circle

So 800 km had to be 1/50th that of Earth

what assumptions must be made regarding the sun for this calculation?

Multiplying by 50 gives 40,000 km which is circumference not diameter, but from there it’s easy to determine

you aren't going to answer are you? 🙂

I'll help you

Let me finish first lmao

oh great

Questions can be saved until the end 🙂

So

Since it was determine that an angle of incidence in 1/50th the arc of a circle, simply dividing the circumference by pi (40,000 / 3.14) = 12,738

Pretty close to the actual number

what do you mean close to the actual number? that's what we are trying to measure. where did the "actual number" come from?
