Do you have evidence to support your claim?
What would you accept as evidence?
Evidence would be a good start...
Maybe something beyond an anecdote.
Do you ever make a meaningful post?
You were explicitly asked "What would you accept as evidence?" and you give the non-sensual answer "Evidence would be a good start..."
Any photograph that has evidence against the flat earth is deemed fake of "Photoshopped", so what is acceptable?
One a clear night (not like tonight) I can see the Southern Cross from near my back door and I certainly cannot see Polaris.
Of course I could give
Another thing is certain, that from and within the equator the north pole star, and the constellations Ursa Major, Ursa Minor, and many others, can be seen from every meridian simultaneously;
So these stars can be viewed from the Northern Hemisphere, though not all from "every meridian simultaneously" as claimed.
Then
But if the earth is a globe, Sigma Octantis a south pole star, and the Southern Cross a southern circumpolar constellation, they would all be visible at the same time from every longitude on the same latitude, as is the case with the northern pole star and the northern circumpolar constellations. Such, however, is strangely not the case; Sir James Clarke Ross did not see it until he was 8° south of the equator, and in longitude 30° W.
MM. Von Spix and Karl Von Martius, in their account of -their scientific travels in Brazil, in 1817-1820, relate that "on the 15th of June, in latitude 14° S, we beheld, for the first time, that glorious constellation of the southern heavens, the Cross, which is to navigators a token of peace, and, according to its position, indicates the hours of the night. We had long wished for this constellation as a guide to the other hemisphere; we therefore felt inexpressible pleasure when we perceived it in the resplendent firmament."
The great traveller Humboldt says:--
"We saw distinctly, for the first time, the cross of the south, on the nights of the 4th and 5th of July, in the 16th degree of latitude. It was strongly inclined, and appeared from time to time between the clouds. . . . The pleasure felt on discovering the Southern Cross was warmly shared in by such of the crew as had lived in the colonies."
Now, I do not agree with some of Rowbotham's conclusions here, but he quite correctly asserts at least that there are stars visible in the northern hemisphere that are not visible in the southern hemisphere and vice versa.
Of these, there is only one, Polaris, the North Star that is not visible anywhere in the southern hemisphere
and only one, Sigma Octantis, the South Star that is not visible anywhere in the northern hemisphere.
