What are quantum fluctuations?

Imagine you're playing with a bouncy ball on a trampoline, sometimes it jumps really high, and sometimes just a little bit. Quantum fluctuations are like those little bits of extra energy that pop up now and then in the universe.

Think of space as a giant trampoline. Normally, things sit still on it, but every once in a while, the trampoline gets a tiny jiggle, that’s quantum fluctuations. These little jiggles aren’t random; they're like invisible bounces happening all around us, even when nothing is there to see.

These tiny energy bursts are super important because they help explain how the universe works on a very small scale. Scientists use them to understand things like particles and forces, just like you might use your trampoline to figure out why some balls bounce higher than others. It's all about those little, invisible jiggles that happen everywhere, even in the quietest parts of space!
