If Earth were shrunk to the size of a grain of sand, the Sun would be a basketball, and the nearest star, Proxima Centauri, would be 6,500 km (4,000 miles) away. 🌌
Space is overwhelmingly... empty. If you were a sand grain in New York, the next closest star wouldn't be down the street—it would be across the ocean in London! Scale is humbling. Thoughts? 👇
