**Script for YouTube Video** [Opening shot: quick flashes of Earth from space, zoom into a brain.] "Did you know your brain can generate enough electricity to power a light bulb? 💡 It’s like your head is a mini power plant, cranking out energy every moment!" [Cut to animation of brain neurons firing like lightning.] "Every time you think, move, or feel, billions of neurons fire signals — producing up to 20 watts of electricity! That's enough energy to light up a tiny bulb, illuminating your thoughts and actions!" [Transition to a galaxy spinning.] "And speaking of power — the Sun is losing an astonishing 4 million tons of mass every second just to keep shining bright in our sky! ☀️ Can you imagine what that looks like?" [Cut to a black hole sucking in matter.] "But nothing beats a black hole. Picture this: a sugar-cube-sized piece of one could weigh more than Mount Everest! ⛰️ It’s mind-boggling how such small things can have such immense weight!" [Zoom in on an hourglass.] "And time? It’s not as constant as you think! Astronauts on the ISS actually age a tiny bit slower than we do down here, thanks to Einstein's wonderful theory of relativity! ⏱️ Better pack your bags for space!" [Final scene: A montage of humans, tech, and stars.] "Your brain, the stars, time itself — the universe is weirder and more amazing than we ever imagined. 🤯 Each curious fact opens the door to even more wonders waiting to be discovered!" [Call to action on screen.] "Mind blown? Hit like and follow for more incredible insights into the universe! 📢"
