So, I came to a discovery on a trip in the car. I saw a jet flying pretty far away from me (one of the planes that makes the cloud trails), and the cloud trail was going, from my point of view, straight down.

Now, in order for this to work, either:
(a) It's falling from an extremely high altitude, and at a relatively slow rate.
(b) It's curving around the apparent curvature of the Earth (i.e. proving a piece of the Round Earth Model).
(c) It's some sort of optical trick that our eyes play on us, or the always relevant
(d) I messed up somehow in my observation, and I'm really not correct in any of my assumptions.

Also, this could be relevant for clouds. If you see clouds on the horizon, does that mean that over on the horizon, it's extremely foggy? And when the sun is on the horizon, are the people over there being fried by intensive heat?

Any thoughts?

lol. that's like the old trick where you take your fingers and pretend to squish someone's head because your fingers look like they're on someone's head.

Um...No it's not. The head-squish trick is due to depth perception, and distances, not the apparently dome-like surface of the sky...They're actually not alike at all...

so you mean to tell me that perceiving the sun to be on the brink of the earth and perceiving my fingers to be squishing someone are different?

explain yourself!

It's option c. Suppose you were standing on the surface of an infinite plane, and a large object were travelling at constant height above the plane, but the object's shadow, which we assume to be directly below the object, were moving directly away from you. Now we can use trigonometry to find the angle above the plane at which the object appears: it will be tan(a/d), where a is the altitude, and d the distance to the object's shadow. Since the altitude is constant, and d is increasing, a/d will be decreasing, so the angle will also decrease. If you are good at visualizing this sort of thing, you can see that the angle will be decreasing without resorting to taking tangents. In other words the object will appear to be lower down, when in fact it's at constant height, but further away. So this observation of yours is just as easily explained by a flat earth as by a round one.

seems very logical to me ...

but when i read this i was wondering if anytime in the future (i hope not so early) the ice wall is melted by the sun? could this be possible end of everything, the armageddon?
I would feel safer if someone could disprove this to me ...

That's been thought of before.  The ice wall melts at the same rate that the RE Antarctica melts, and I'm fairly sure it's not melting at an amazing pace.  Besides, the ice is landlocked anyway, so even if it melted, there is a mountain range it sits on that sill holds the water in the boundaries of the worlddisc.

Well, that obviously puts you above most other Round Earthers, then.
