6 Scientific Evidences That Ruined Long-Held Beliefs🔬🤯

We’ve long accepted that Earth isn’t the center of the universe, but here’s a mind-blowing twist: our universe might not be unique either. Modern physics suggests we could be part of a multiverse—an infinite collection of universes with different physical laws. That makes us not just a tiny dot in space, but a tiny dot in a potentially infinite cosmic sea. Existential crisis, anyone?

The idea of sleepwalkers acting out their dreams has been a staple of pop culture for ages. But science says otherwise. Sleepwalking happens during the deep, non-REM stages of sleep—when you’re not dreaming. It’s caused by a disconnect between your motor control (which is active) and your consciousness (which is out cold). So if someone’s wandering the halls at 3 a.m., they’re not chasing dream dragons—they’re just stuck in a weird sleep state. 

We’ve all heard the joke about goldfish having a 3-second memory, but it’s totally false. Studies show goldfish can retain information for months and even learn patterns. They’ve been trained to recognize people, navigate mazes, and even associate certain signals with feeding time. In short, they’re not as forgetful as us after a long day at work. 

You’ve probably heard that lightning never strikes the same spot twice, but that's far from true. Lightning strikes can, and often do, hit the same location repeatedly, especially if it’s a tall structure like a skyscraper or a tree. The idea of it being a rare occurrence likely stems from the belief that lightning has a "random" pattern, but in reality, it's all about the right conditions.
