Get your flat earth out of here. Please study more geometry. This happens because HS do not take seriously their mathematics.
What does any of this have to do with a flat earth? The
Parallax effect is the apparent change in relative positions of objects when the observer moves. This change is more readily apparent the closer the objects are to the observer.
I’m sure a geometric model exists that describes this but a firm grasp of the numbers aren’t strictly necessary to understand this. Take a thumb and put it in front of your face, turn your head. Parallax. Move your thumb as far away from yourself as you can and do the same. Parallax, but less discernable. Look at that mountain and those clouds out in the distance and take two steps to the left. I’m sure there was some kind of parallax effect, but i’d be very surprised if you could tell me what.
(Actually let’s circle back to me being called a flat earther for some reason. If you take a look at a sunset on the horizon, then climb a ladder, you can actually see the sunset again. This is why the ramadan fast is observed at different times on the upper floors of skyscrapers like the Burj Khalifa on than the ground. Parallax, and also proof the earth’s surface is curved.)
So the answer to the rhetorical question i asked in the previous post is “well we do observe that, actually. at least now that we’ve got these really good telescopes”
Galileo had roughly two arguments to support heliocentrism, which he used not just to describe how he thought how the natural world worked, but also, following from that, how one should interpret the parts of the bible that contradicted that worldview: one was the theory of the tides, which was just flat out wrong. Wrong enough that it could be disproved by his peers. The other was that stellar parallax was real, but actually the stars are reeaaally further away, by orders of magnitude, than anyone had previously considered plausible, but also waaaaay bigger and waaaaaay brighter to the same extent, so it’s hard to measure parallax of the stars from the yearly movements of the earth; but just trust me bro.
Those arguments were published in a book in which he wrote a stand-in for the pope, supporting geocentrism, named simplicio.
It turns out that second argument was right, but again, evidence in his favor didn’t show up for 200 years, and his other argument was, not to put too fine a point on it, shit. So while I’m not saying the church was right to call an inquisition, would anyone really be surprised?
Anyway Pope John Paul II said sorry to Galileo, all it took was the better part of 400 years.
