Anyway, in the 6th century BC he reasoned that if the moon was round then the Earth must be too. But not this guy, Pythagoras, who you might know as the guy who invented Pythagoras' Theorem. Yeah, that was pretty much what most people thought for a long time. ONE: Sure, sure, sure and what happens when you reach the edge? Do you just fall off? I still think it makes sense for it to be flat. Now, today we know the Earth is round because of, well duh, technology and like we've been to space so we can see it and go "yeah it's round". You see when objects like planets spin and spin and spin, things on the outer edge have to move faster than things on the inside to keep up and that causes a sort of bulge along the equator. You know not exactly a sphere but close enough so that everyone thinks it is. ONE: I think Earth should be an irregularly shaped ellipsoid. Technically the Earth and other planets are more of an. The same thing is happening to all the other planets in our solar system, which is why they're also round, well kinda. All of us and all the stuff the Earth's made of are being pulled towards the centre of the planet with equal force. Which is why people on the other side of the planet don't fall off. The force of Earth's gravity pulls equally from all sides. You know that force that attracts everything to everything else. The real reason why the Earth is round is a lot less science-fiction and a lot more science-faction or scientific. They're straight to the point.Īnd that my dear BTN viewers is not the reason why the Earth is round. But once we've decided on the shape of Earth you can put as many pyramids on it as you like. ONE: For the last time we're not going with a pyramid. TWO: What about a pyramid? Then we can hide treasures inside it. ONE: I don't know, I still think a cube is the right shape. Somewhere a long time ago, like more than 4.5 billion years, a committee was meeting to decide the shape of our planet. EVIE: Hey BTN it's Evie and I'm wondering why is the world round? Also, big fan, love you guys.
