Quick question:
A person in southern South America and southern Australia are both looking south one night. "South" on your map for them is two very different directions. Yet both looking "south" they can see the same stars. How does that work out?
Edit: To be specific they are looking at the constellation the Southern Cross. At any time in night that is going to be straight South in direction in the Southern Hemisphere yet according to your map they would be looking in all sorts of different directions.
I'd like to point out to any people debating me, that their compatriots went as far as to say there is no sky. Yeah. After that, I'm not sure I have to defend anything, because anything I say is a more reasonable assertion.
But I will anyway, because you deserve to know THE TRUTH. :dramatic:
The simple answer? Because this world we live in isn't fully real. In a round Earth, the SAME problem exists (I had to use Brazil to get a Lat/Long on both because one is also a country the other is not).
Let's look at Brazil in the capital, since it's in South America. 15°47′S 47°52′W (take note of that West hemisphere) is roughly 9,687 miles from Australia's capital at 35°18′29″S 149°07′28″E . It's basically the other side of the world.
Yet, a round Earth, unlike a flat Earth, also has basically a hill angling perception even further. In other words, in a flat Earth, I could claim the dome or Firmament was somehow funneling my perception so that I could see southern constellations but not northern (even though if it were just a matter of distance perception, this would be pretty difficult to rationalize, like I say, fake). But with a round Earth, we not only have to explain away basically a screen (much like one of those backgrounds they put in movies for car scenes) but have to explain why two people standing around a hill that slopes away are going to at all see the same sights.
I think I can see Orion year-round despite what anyone in a lab coat says, so that's just not so. So the simple answer is you shouldn't be able to see the same constellations in the sky based solely on being it the southern hemisphere. But you can. More importantly, you more easily could just by looking up since there are no major perspective issues, while ummm....
Orbit problems.
