Do you agree or disagree with the following statement: given a model like this: https://files.catbox.moe/9y3dhw.png

And the explanation given in that video, it is possible to create a map of the Earth which shows every point on the Earth where the sun is visible above the horizon, and every point on Earth where the sun is not visible above the horizon

I am not sure what you mean as clearly the sun is not visible from everywhere.

Think of it like any light, it‘s transmission distance is limited.

There are bigger worries in original video.

I am not sure what you mean

I mean that the video proposes a model. Do you agree or disagree that we can use the model to make predictions?

For example, the model proposes that due to refraction, the sun cannot be seen from a certain distance away. We should be able to measure that distance predict where on Earth the sun would be visible, given some position. Basically, it'll be a circle with the sun at its center, like this: https://files.catbox.moe/jju3j4.png

This is not a "gotcha" question. It's totally okay if it takes several tries to get the radius of the circle correct. The ultimate point is, the model proposed in that video is still different than the globe-earth model, and therefore we should be able to conduct an experiment that tests those differences.

But this all depends on your answer: do you agree or disagree that we can use the model to make predictions?
