Did you know that our universe can "ring" like a bell? When massive events, like galaxy collisions or black hole mergers, happen, they send out ripples of gravitational waves, kind of like cosmic vibrations! These waves travel through space, making the universe hum in a way that’s completely mesmerizing. And that's just one cool space fact! For example, did you know a day on Venus is longer than its year? Or that there might be more stars in the universe than grains of sand on Earth? Space is full of amazing and mind-boggling wonders!
