## Resource

Way, way back in the day, the entire universe was crammed into a space smaller than a baseball. It's like the ultimate cosmic game of squeeze-in. Then, the universe decided to throw the ultimate expansion party. It started stretching and growing, getting bigger and bigger. Galaxies formed, stars ignited, and planets, like our very own Earth, came into existence. So, next time you're watching a baseball game, just think, the universe was once small enough to fit right in your hand. Learn more about your ad choices. Visit megaphone.fm/adchoices
