Off course the world is a disc - I don't feel I'm on a ball. Hello, nice people from around this beautiful flat disc called earth! I know the hipe of this subject has diminished but since I've got in contact with this movement not a long time ago I'm kinda addicted to it. Not sure why but I find rather interesting, not the 'theory' itself but the fact that so many people invest their time and reputation as sane people to embrace something that improbable and inconsistent. We could measure the diameter of Earth's crust more than two thousand years ago in ancient Greece. Aristophanes, I think that was his name, used only two sticks and some math to get to the conclusion we live in a ball 40000 kilometres wide. Fast forward a lot of time, past the space exploration, the moon landing, the GPS system and many other realizations and all of the sudden arises from the depth of internet an army determined to refute the conspiracy that hides the real shape of the Earth. A few days ago I've watched a documentary on Netflix about them - they're so entertaining! throughout the vídeo I could feel at least a little bit empathetic toward them, they might only be somewhat needy and perhaps need something to feel brighter than everybody else at least once in their life. The holes in the theory are really big, and I've learned a lot of physics from the material that refutes their assertions, like the movement of the planets on the sky, the law of perspective, lenses of cameras, etc. I would like to highlight 2 moments in that documentary. The flat-earthers came up with two very clever tests - one that uses a super expensive and sensible laser gyroscopic that should be able to detect the earth spin and another one consisting in three aligned posts with holes at the same hight, those holes, therefore, should disprove the curvature while a light beam was cast through those three holes. Their reaction to the results is priceless. Are many rabbit holes in youtube where you can get a glimpse of very strange conspiracies, like the moon would be a hologram, it's a fake object, plains are disguised demons, the sky is fake, dinosaurs had never existed and many others. If you're like me grab a popcorn bucket and delight yourself with ingenious people revealing the secrets of the world from their couch. Next entry I will talk about what worries me in that way of reasoning and the effect we can already see taken place in my nation. Flat-earthers has conquered the power in Brazil and that's when it stops being funny.
