Why We Haven't Met Our Cosmic Neighbors

The universe is a big place. Really big. And it's been around for a long time. So, it's not a stretch to think that life exists somewhere out there. But if aliens are real, why haven't we heard from them? A scientist from NASA has an idea. He thinks it's not because they're hiding or using some fancy tech we don't know about. It's simpler than that. They might just be like us, stuck on their own planet, following the same rules of physics. So, why haven't they called? Well, space is huge. Radio signals get weaker the further they travel. By the time a message from an alien civilization reaches us, it's probably just noise. And even if they wanted to visit, it would take forever. Our fastest spacecraft, Voyager 1, is zooming along at 38, 000 miles per hour. But even at that speed, it would take 75, 000 years to reach the nearest star. The Milky Way is 100, 000 light-years across. That's a lot of space. Even if an advanced civilization colonized a million star systems, it would barely make a dent in the galaxy. So, we're not alone. But we're also not exactly next-door neighbors. The universe is so vast that we might as well be. It's a lonely thought, but it's also a reminder of how special our little corner of the cosmos is.
