http://youtu.be/er_T-G2XVvA Skyquakes are mysterious booming sounds that seem to come from the sky, and no one knows exactly what causes them. These loud booms can be so powerful that they shake buildings and scare people, but they leave no signs of an explosion or earthquake. People have reported hearing skyquakes all over the world—in places like the U.S., Japan, and even Italy. Some scientists think the sounds might come from meteors entering the atmosphere or underwater earthquakes sending shockwaves through the air. Others suggest they could be caused by atmospheric changes or even secret military tests. Whatever the cause, these eerie booms are unpredictable, so if you hear one, don’t panic—just know you're part of a worldwide mystery! Animation is created by Bright Side. ---------...

http://youtu.be/KwFs_aS_3jQ Phoenix, Arizona, is smack in the middle of the desert, yet over 5 million people call it home! Why? It’s all about clever planning and modern tech.

The way we measure time, like seconds, minutes, and hours, is based on how Earth moves around the sun, but that’s just a human-made system. Some physicists argue that in the grand scheme of the universe, past, present, and future all exist at the same time, and what we experience as "now" is just our perspective. This idea comes from theories like Einstein’s relativity, where time can stretch or shrink depending on speed or gravity. Without humans to track it, "time" might not even exist in the way we understand it—it’s more like a big, flexible thing. It's super weird to think about, but it makes you wond...
