Future Space
For most of human history, the question “how many planets are there?” seemed like a no-brainer. Look up at the sky, and you could spot five bright dots, each moving against the backdrop of fixed stars. Mercury, Venus, Mars, Jupiter, and Saturn—those were the planets. Simple, right? But that simplicity wasn’t because ancient civilizations had figured everything out. It was more like they’d walked into a dark room, found a flashlight, and decided the small circle of light it illuminated was the entire universe. What they didn’t know—what they couldn’t know—was that their flashlight was just skimming the surface of something far bigger and more complex.
