P A N

i'm gonna do an update of where we are. I'll list the questions and their answers.

1st question: How far away is the horizon?
Answer: 2nd question: Can a situation or experiment be cited as evidence that an enclosed system of gases can exist within a vacuous surrounding without a barrier or seal?
Answer: "Gravity"

personally, i'm not happy with the answer on the second one. gravity cannot be proven to exist. it is accepted as fact, which is very different from being fact. the reason we need gravity is so we don't fall off the ball. to a flat earther, this translates to "we need an imaginary force to describe the utterly anomalous ball-earth characteristics such as curved water and a gas existing next to a vacuum." obviously, i asked this question to say this. there is no other example of gasses existing next to vacuums that we can test. we rely on the space program for this knowledge.

i guess the third question is ready, then.

the atmosphere is said to work like a lens in terms of how sunlight passes through it. how is light supposed to behave when it enters through the convex side of a lens and exits the concave side?
