Here’s the highly abbreviated version of how humans discovered that the Earth is round. So, how did philosophers, explorers and scientists like Aristotle, Biruni and Magellan figure it out hundreds of years ago? The short answer is astronomy, mathematics and exploration. Well, for one, there are thousands of photos from space that show the Earth as a globe, but those have only been around for half-century. But how can us scientific fledglings really prove it? Thanks to scientists and philosophers from the past, we’ve got exacting science that proves the fact. In fact, we’ve known this for thousands of years.
