“The large bodied objects in space are attracted to each other and will merge together in order to be as stable as possible. “Things in nature like to be as stable and decrease surface area as much as possible,” Shaub said When planets are formed gravity pull the matter into which the planet is made. The myth of Columbus’ supposed flat earth theory is tempting: It casts the explorer’s intrepid journey in an even more daring light. In a simple way to put it, gravity truly is what causes the Earth to be round. “Think of a ball of clay, if we want to decrease surface area, we will mold it/form it into a small ball,” Shaub said. Emily Shaub shares even more information about the science behind the true shape of the Earth. Now we may not having much photo evidence but if you ever look at the moon during a solar eclipse, you can see the Earth’s round shadow. Studies from not only NASA, but also experiments form the ancient Greeks, prove that the Earth is very much a sphere. Geodesy provides accurate measurements that show Earth is round.” But how can we find the real answer? Using science.Īccording to NASA, “Scientists use geodesy, which is the science of measuring Earth’s shape, gravity and rotation. If it is in fact as round as a basketball or is it as flat as your math homework? Now there are many arguments on how people think the earth is flat and vis versa for if it’s round. But one heated debate is if the Earth is flat. How a piece of paper is a rectangle, but a stack of papers is a rectangular prism. We have been learning the difference between 2D and 3D shapes for all our lives.
