Quantum tunneling is like when a ball rolls toward a wall, but instead of stopping, it just passes through the wall. It's like magic! Imagine you're trying to get out of your room, and there’s a door that’s closed, but somehow, you just appear on the other side without touching it. That’s what quantum tunneling is: tiny particles passing through barriers without needing to go all the way around them.
Examples
- A ball rolls toward a wall, but it just passes through the wall instead of bouncing back.
- A person walks into a wall, but they just walk straight through it.
