gravitational waves

Gravitational waves are ripples in space-time caused by the movement of massive objects, like stars and black holes. Basically, when these objects move, they create waves, just like when you throw a pebble into a pond, it creates ripples in the water. The difference is that gravitational waves move at the speed of light. Here’s an analogy to help you understand: Imagine that you are in a giant trampoline. If you jump in the middle, you’ll create a wave that spreads out to the edges. That’s what happens when a massive object moves around in space, and it creates a gravitational wave. Fun Fact: Gravitational waves are so small that it took scientists 100 years to find them!
