Hello, I am a 3rd year physics student, and I'm here to put and end to this discussion...
The reason why earth looks round from up in the sky is as follows. I'm sure you all have seen that when you put a pencil halfway in a glass of water, it appears to be broken. This is because water is denser than air and light rays bend when the density of the medium changes. This is known as the Snell Law.
Have you ever seen on airplanes' info channels the outside temperature? It goes all the way down to a few degrees, because atmosphere gets colder as you ascend. Cold air is denser than hot air - this is actually why hot air balloons fly! So, when you are looking down from a plane to the surface of the earth, you're looking through the atmosphere that gets warmer (and therefore less dense) as you descend. This causes light rays from the earth to bend and makes the surface look curved - just like the pencil in the water getting broken. It's not a sharp break as in the pencil example but a smooth curve, because the temperature and so the density changes gradually, not suddenly.
This notion is very entertaining, but you haven't explained some important things:
-how severe is the refraction of light through air within reasonable temperature perimeters?
-what of high pressure/low pressure currents in the air? If what you say is true, and air refracts light so severely, then we should be able to see high pressure/low pressure currents clearly distort the horizon. Yet we don't.
This was one of the things that fooled our ancestors into believing earth is round. The so called "fact" really shook the religious world because it was against what was believed so far. Then, when the scientists realized they were wrong, they just decided to play along with the whole scam because if they revealed their mistake, religion would get back its power and they would lose the eternal battle. Please, think about it, it's all out there, it's the biggest scam on earth's history!
Utterly rediculous.
1) Religion already has alot of power.
2) Such a scam can never be maintained. Science is self-correcting. All scientific knowledge is constantly being tested and retested. If a hypothesis or a theory does not stand up to scrutiny now, or later, it will be discarded for a new one that fits better. The flat geocentric earth is one such hypothesis that was discarded in light of overwhelming evidence.
what makes you think that you're in any way better than a FISH? The similarity is even more obvious with you...
I didnt say it's exactly like them, I said its similar to that... Just google spherical abberation and you'll see.
Dont confront me without knowing any science! Gosh!
If we saw only how our eyes picked up light, everything would be upside-down and in individual "pictures". The brain compensates for the spherical abberation our eyes feed us. The brain is also capable of meshing together the individual signal transmissions from our nerve cells, so that we see everything in movement rather than in single "pictures".
