The universe is expanding — but expanding does not mean falling. This video explains a common confusion about space, gravity, and direction. We often imagine the universe like an object inside a larger space. Physics says something very different. The universe is not inside space. The universe is space. Falling requires an external force and a defined “down” direction. On a universal scale, neither exists. Gravity works locally — Earth, the Sun, the galaxy — not globally across the entire univer

What if the universe isn’t just expanding — but slowly twisting too? 🌀 A new study suggests the entire universe may be rotating so gradually it takes 500 billion years to complete a single turn. We’d never feel it — but this subtle cosmic spin could help explain the Hubble tension, the long‑standing mystery over why different measurements disagree on how fast the universe is expanding. If true, this faint rotation could gently bias expansion measurements, bringing them back into harmony. It’s a

🌌 Did you know the universe is still expanding—and faster than ever? 🚀 But here’s the mind-bending question that keeps scientists awake at night: what lies at the edge of it all? There’s no “wall” or “end” to bump into. Instead, space itself is stretching, carrying galaxies farther apart. The “edge” isn’t like the edge of a table—it’s more like the surface of an inflating balloon, with no true boundary. But beyond that? 🤯 Nobody knows. Some theories suggest infinite space, others hint at para
