Anyone would say that there is enough evidence that the Earth is spherical. However, and against all logic, there are more people who assert that our planet is flat. If you ever encounter one of them, you can use this argument. If you do not convince her, there is nothing to do.(Evidence That Dismantles Theory of the “Flat Earth” )
How could it be that, at the same moment, different stars can be seen in the sky of Madrid and in the sky of Buenos Aires?
The explanation for that is precisely that the Earth is spherical. The stars visible in the sky are not the same because the perspective of the observer varies. If the Earth were flat, we would always see the same stars, no matter if we were in the northern or southern hemisphere. Okay, but maybe your interlocutor is reluctant to believe this because he has never been anywhere else on the globe, and even less has he done so by going out at night to look at the stars. In that case we have one last card to play. The rotation of the stars.(Evidence That Dismantles Theory of the “Flat Earth” )
The video above is a timelapse taken for hours from the Mojave Desert. What is seen in the sky forming a kind of stelae are the stars when moving. The rotation of these stars rotates clockwise in the southern hemisphere, and vice versa in the northern hemisphere. The reason is that it is not the stars that rotate, but the point of view of the spectator, which is on a sphere that rotates on itself.(Evidence That Dismantles Theory of the “Flat Earth” )
No terraplanist theory is able to explain this from the perspective of a dome on the supposed Earth disk unless they resort to sorcery or extraterrestrials by projecting holograms. If they do and we just have to make a discreet mutis by the forum and leave them with their theories. They have chosen not to take into consideration anything that might make them change their minds.
