When we talk about how big the universe is, we’re not just talking in kilometers or light-years. we’re talking about something almost beyond human comprehension. Our Earth, which feels huge to us, is just a speck beside the Sun, which itself is one star among billions in our galaxy. The Milky Way stretches about 100,000 light-years across, and that’s just one galaxy out of at least 2 trillion in the observable universe. What’s more insane? The universe is still expanding, faster than light, meaning some parts will forever be out of our reach. So how big is the universe? We still don’t… and maybe never will, truly know how big the universe is.
