Sunrise/Sunsets.. mm..

Hi.. Thanks for your welcome.. so there are another physicists from South America here, who are they?

I've read that text about sunrise and sunset and I found it foolish. The sun, in general, would appear high above the horizon, just basic trigonometry guys. That explanation would work only if the earth were much bigger, or the sun much closer ..

According to your map

Case 4:  You use Eratosthenes experiment to prove a round earth, when in fact this experiment  requires the assumption of a round earth.  When you correctly assume the Earth is flat, the same experiment demonstrates the true distance to the sun.

Actually the stars provide a good reason to think that the earth might be round.  The stars seem to be rotating around us as if they were attached to a giant celestial sphere rotating around us.  Just trace out their paths all night, and they make perfect circular arcs across the sky with the north star at its pole.  In addition, as every navigator knows, the north star appears to raise one degree for every 69 miles traveled northward.  This suggests that the earth must be a sphere.

This observation is quite related to mine expressed in the thread I started. If the polar star were in some place above the flat earth it would be just above the north pole. Therefore, as you go south the star would reduce its altitude but not at a constant "angular velocity", its altitude would be arctan(h/d) where h is its elevation above north pole and d is the your distance from north pole. As you go further south the polar star would reduce its astronomical altitude at a lower rate. We do not see that, it appears to reduce its altitude one degree for every 69 miles traveled in a very precise way... 

Like Evangelists you believe that science is out to destroy you and the world, but it is simply the pursuit of logically based facts.

Can you please explain to me what studies you have participated in to give you sufficient qualifications to come out and claim that the earth is flat and deny the simple facts. Like Evangelists you believe that science is out to destroy you and the world, but it is simply the pursuit of logically based facts. Where are your facts, where's the hard evidence to back up your claim, all i see is misenturpreted pictures and gassey unfulfilled explanations followed up by more than inadequite diagrams.

The sun path explanation can be found here: http://www.sacred-texts.com/earth/za/za27.htm

Note that the motion of the sun does not in itself have anything to do with the shape of the Earth.  Some have believed it to pass under the flat earth.

According to your map, south celestial pole canīt be the center of any gear just because observers in Australia, South Africa and South America would place it at entirely different directions. Where the fuck are the stars of the southern celestial hemisphere? The directions pointing towards any southern star (considering simultaneous observations at different parts of the world) would not converge to any point.. Are they illusions? 

I can't imagine how do you explain paralax, precession, nutation ... OMG! too much for a single post and this is just the beginning..

You now have to build an entirely new science...

Cheers

So, if the sun is much closer than 3000 miles, how do you explain the Eratosthenes experiment?.. I thought that you would say something related to atmospheric refraction and all that jazz..

If we are supposing the earth to be flat, why are we questioning it?

Once again...If the sun were much closer than 3000 miles (this is the only way to make sunsets and sunrises possible in FE theory) the Eratosthenes experiment would remain unexplained..

Once again Tom.. That page says that the sun is approximately 2000 miles above. That's not close enough
